Heat Exchanger Technology Overview
Lytron’s broad range of heat exchanger technologies combined with five decades of thermal transfer experience
enables us to offer tailored solutions for a wide range of applications. Our four types of heat exchangers
can all be customized and integrated into subassemblies.
Tube-Fin Heat Exchangers
6000 Series, OEM Coils, Aspen, and 4000 Series
Our tube-fin heat exchangers consist of copper or stainless
steel tubes expanded into copper or aluminum fin. Tube-fin
heat exchangers are cost effective and offer good heat removal
for a wide range of applications including lasers, electronics,
compressor cooling, semiconductor processing equipment, and
solder reflow ovens. Our copper tubed 6000 Series and OEM
coils, and stainless steel tubed Aspen and 4000 Series offer
compatibility with a wide range of common coolants.
Flat Tube Oil Coolers
ES Series
Standard Heat Exchangers
ES series oil coolers are designed for optimum cooling
with poor heat transfer fluids such as oil and ethylene glycol/water mixture (EGW). The aluminum flat tube fluid
channels are vacuum-brazed with aluminum fin and a frame
for a rugged and lightweight construction. They are ideal for
cooling x-ray tubes, aircraft engines, hydraulic fluid, and high
speed spindles.
Plate-Fin Heat Exchangers
Vacuum-brazed aluminum plate-fin heat exchangers are
our highest performing heat exchanger. They can be used for
air-to-air, air-to-liquid, and liquid-to-liquid cooling. All plate-fin
heat exchangers are custom designed to match your precise
performance and size requirements. Applications include
condensers, evaporators, environmental cooling systems, and
radar cooling. Their high performance/weight ratio also makes
them popular for airborne applications such as cooling gearbox
oil and transmission oil with ram air or jet fuel.
Liquid-to-Liquid Brazed Plate Heat Exchangers
Liquid-to-liquid brazed plate heat exchangers utilize stainless
steel plates brazed together in a counterflow configuration.
This offers high liquid-to-liquid cooling capacity in a compact
package. We offer both copper-brazed and nickel-brazed versions
for compatibility with a wide range of coolants. Applications
include district heating/cooling, heat recovery, and laser cooling.

Corrosive fluids
(e.g. Deionized water)
Coolant compatibility with wetted surfaces must be considered when selecting a heat exchanger technology. A
copper fluid path is compatible with water and most common coolants. A stainless steel fluid path is necessary
when using deionized water and other corrosive fluids. Aluminum offers excellent performance with ethylene glycol/water mixture (EGW), oils and other fluids, but is not compatible with untreated water. The table below
shows fluid/heat exchanger compatibility.

This chart compares the performance of different heat exchanger technologies. Performance is shown as Q/ITD,
the heat load divided by the difference in incoming temperature of the liquid and air. Units are not shown so that
technologies can be compared regardless of size.

The 6000 Series is a high performance heat exchanger with copper tubes and fin. It delivers efficient heat transfer and
maximum reliability in a compact package.
High cooling capacity in a small envelope: The 6000 Series is engineered for performance. Its high tube density
results in maximum heat transfer. The seamless copper tubes are expanded into copper fin (aluminum for the 6340)
with an extruded full collar which ensures excellent metal-to-metal contact and improves the thermal performance.
Integrated fan plate for improved performance and convenience: The 6000 Series’ integral fan plate acts
as a plenum to distribute the air flow uniformly through the core, thus maximizing performance. It also enables
easy fan installation.
Reliable, leak-free, and robust: Lytron heat exchangers are designed for reliability. Our thick-walled (0.028˝/0.7 mm)
seamless copper tubing and fluxless silver-brazed joints ensure the integrity of the fluid path. The unit is painted for
long life, even in corrosive environments. All 6000 Series heat exchangers are pressure tested to 150 psi (10.3 bar)
to guarantee reliability.
Compatible with water, ethylene glycol/water mixture (EGW), and other common coolants.
Customization Options
Custom 6000-Series style heat exchangers can be manufactured in any size
and tube configuration to match your demanding thermal requirements.
Variations in inlet/outlet position and/or fittings can be accommodated and
a selection of paints and other coatings is available. Assemblies including
fans and other components can also be supplied.
See page 92 for more custom heat exchangers.

Great value: We carefully selected the materials, tube layout, and fin for low manufacturing cost, and eliminated
some of the cosmetic features found in the 6000 Series. All these cost savings have been passed on to you!
Leak-free, reliable, and robust: Our OEM coils use the same thick (0.028˝/0.7 mm) walled copper tubing and
fluxless silver-brazed joints as our 6000 Series to ensure the integrity of the fluid circuit. Galvanized side plates
provide superior strength and are corrosion-resistant. All of our OEM coils are 100% leak tested to 150 psi (10.3 bar).
Compatible with water, ethylene glycol/water mixture (EGW), and other common coolants.
Standard Heat Exchangers
OEM coils are the ideal solution for large volume, price sensitive users who need a high quality, cost-effective part but
do not require the additional features of the 6000 Series.
Both the 6000 Series and OEM coils offer high performance and reliability. The 6000 Series uses copper fins, is
painted black for corrosion resistance, and includes a fan-plate. The OEM coil has a different tube configuration,
uses aluminum fins, and is unpainted with galvanized side plates. OEM coils are best suited for the price-sensitive,
high volume customer where the appearance is not critical, for example where the heat exchanger is hidden in
the equipment.

The Aspen stainless steel tubed heat exchanger combines low price and low pressure drop with excellent heat transfer
and superior fluid integrity.
• Our best value stainless steel tubed heat exchanger: The Aspen offers excellent value — 80-90% the performance
of competitive products at approximately half the price. We achieved this by using fewer tubes and increasing the
fin density to balance the air and liquid sides. Our single piece formed aluminum frame/fan plate further reduces
cost and weight.
• Highly reliable: Like all Lytron heat exchangers, the Aspen is designed for reliability. 316L stainless steel fluid path
with 0.02˝ (0.5 mm) wall thickness maintains deionized water and will not react with corrosive liquids. Aspen heat
exchangers are 100% leak tested to 150 psi (10.3 bar).
• Extremely clean: Our proprietary manufacturing process expands the tubes into the copper fin without the use of
oils and our liquid return design eliminates potential particle trapping sites, which can contaminate cooling fluid.
Argon-purged welded joints further ensure cleanliness.
• Low air and liquid side pressure drop: The short fluid path minimizes the liquid side pressure drop, and our tube
spacing and high performance fin reduce air side pressure drop.
Customization Options
Custom Aspen style heat exchangers can be manufactured in various sizes
and tube configurations to match your thermal and size requirements.
Variations in inlet/outlet position and/or fittings can be accommodated and
a selection of paints and other coatings is available. Assemblies including
fans and other components can also be supplied.
See page 92 for more custom heat exchangers.

• High cooling capacity in a small envelope: The 4000 series is engineered for performance. It has a high tube
density for maximum heat transfer. Heavy-walled (0.028˝/0.7 mm), seamless stainless steel tubes are expanded into
copper fin with an extruded full collar. The copper fin and the excellent metal-to-metal contact between the tube
and the fin collar further increase performance.
• Compatible with deionized water and corrosive liquids: All the wetted surfaces in the 4000 Series are 316L
stainless steel, so it is ideal for use with high purity and/or corrosive coolants such as deionized water.
• Integrated fan plate for improved performance and convenience: The 4000 Series’ integral fan plate acts as
a plenum to ensure uniform air-flow distribution through the core, thus maximizing performance. It also enables
easy fan installation.
Standard Heat Exchangers
The 4000 Series is our highest performing stainless steel tubed heat exchanger. It is ideal for applications where
deionized water or corrosive fluids are used, and a high efficiency, compact unit is required.
78
• Rugged and reliable: The argon-purged welded stainless steel frame and fan plate offer durability and strength.
4000 Series heat exchangers are 100% leak tested to 150 psi (10.3 bar).
Aspen or 4000 Series? The Aspen offers 80% the performance of the 4000 Series at approximately 50% the cost.
Where high performance in a small envelope is required, the 4000 Series is the best option. However, when a slightly
lower performance/size ratio is acceptable, the Aspen offers better value. The Aspen also has lower air and liquid side
pressure drops.

Internal view of Lytron’s
aluminum flat tube
ES Series oil coolers are engineered for high performance with poor heat transfer fluids such as oils and EGW. They
provide up to 2.5 times greater thermal performance per unit volume than competitive models.
• High performance: The ES Series uses Lytron’s unique aluminum flat tube technology, which has multiple extended
surface channels in each tube. These tubes provide maximum cooling by having a large surface area in contact with
the fluid (approximately 12 in2 (77 cm2)/linear inch of tube). Lytron’s air-side fin geometry efficiently channels air
across the fin surface to further boost heat transfer capability.
• Clean and reliable: The fluxless vacuum-brazed construction results in a clean, rugged, and highly reliable part with
excellent thermal contact and mechanical strength.
• Low pressure drop: Our flat tube fluid channels and efficient header manifold result in a very low pressure drop so
smaller, less expensive pumps can be used.
• Lightweight: The all-aluminum, vacuum-brazed construction is lightweight.
Customization Options
Oil coolers can be manufactured in different sizes and tube widths, and
with custom inlet/outlet configurations. Curved heat exchangers can be
manufactured as the flat tube can be bent without buckling or damaging
the internal channels. Assemblies including fans and other components can
also be supplied.
See page 92 for more custom heat exchangers.

Standard Heat Exchangers
Large heat transfer surface
Aluminum vacuum-brazed plate-fin heat exchangers are widely used in military, aerospace, and other
high performance applications because they offer excellent thermal transfer capacity combined with small
size and weight. They are all custom designed as every requirement is different.
• Superior performance: This heat exchanger technology, which consists of finned chambers separated by flat plates,
offers our highest thermal performance. The plates and fins create a large surface area for heat transfer, and the
fins create turbulence in the fluid to further improve performance.
• Lightweight: The all-aluminum construction offers superior performance/weight ratio.
• Completely customizable: All our plate-fin products are custom designed so that we can supply you with the
most efficient, compact, and lightweight part possible. The number of plate and fin layers, the size of the plates
and fin, the height of the fin, and the type of fin are carefully selected for optimum performance. Manifold ducting
and mounting brackets are welded in place as required, and a wide variety of paint, Milspec, and other coatings are
available. Contact Lytron to discuss your requirements.
• High reliability and cleanliness: The plates and fin are assembled in an environmentally-controlled room for
maximum reliability and cleanliness. Also, our numerically controlled vacuum brazing process and robust fixture
designs ensure complete metallurgical bonding between the fins and separator plates for ruggedness and quality.
• Custom testing/certification: Complete shock and vibration testing and agency approvals are also available.
Now Available in Titanium
Lytron has developed the technology to make titanium plate-fin heat
exchangers. These combine excellent thermal performance, high strength,
and light weight and can be used at temperatures up to 1000°F (537°C),
overcoming the temperature limitation of aluminum products. Call

brazed plate heat exchanger
• High performance in a small package: Lytron’s liquid-to-liquid heat exchangers are up to 80-90% smaller in
volume and weight than a conventional shell-and-tube design. The counterflow design utilizes stainless steel sheets
stamped with a herringbone pattern of grooves, stacked in alternating directions to form separate flow channels
for the two liquid streams. This allows 90% of the material to be used for heat transfer, making it extremely efficient.
• High reliability: The plates are brazed together at the edges and at a matrix of contact points between sheets,
ensuring that the heat exchangers are highly reliable and rugged.
• Copper- and nickel-brazed versions for compatibility with a wide range of fluids: We offer copper-brazed
units for use with water, EGW, and other common coolants. Our nickel-brazed units are appropriate for use with
deionized water, high purity, and corrosive fluids.

Selecting a Heat Exchanger
1. Cooling Liquid
In order to select the correct Lytron heat exchanger or oil cooler, you must first determine the required thermal
performance for your application. Use the example shown below:
Step 1: Application Data
Liquid type:
Required heat load (Q):
Temp. of incoming liquid (Tliquid in):
Temp. of incoming air (Tair in):
Rate of liquid flow:
Water
3,300 W (11,263 BTU/Hr)
80°C (176°F)
21°C (70°F)
2 gpm (7.6 lpm)
Step 2: Select the heat exchanger product series
Choose an aluminum, copper, or stainless steel heat exchanger based on the fluid compatibility. Aluminum tubing is
usually used with light oils, or ethylene glycol and water solutions. Copper is normally used with water. Stainless steel
is used with deionized water or corrosive fluids.
Step 3: Calculate the initial temperature difference
Subtract the temperature of the incoming air from the temperature of the incoming liquid as it enters the heat
exchanger.
ITD = Tliquid in - Tair in
= 80°C – 21°C = 59°C (or 176°F – 70°F = 106°F)
Step 4: Calculate the required performance capability (Q/ITD)
Divide the required heat load (Q) by the ITD found above in step 3.
Performance capability = Q = 3,300 W = 56 W/°C or 11,263 BTU/HR = 106 BTU/Hr°F
ITD
59°C
106°F
Step 5: Select the appropriate heat exchanger model
Refer to the thermal performance graphs for the heat exchangers selected
(Performance graphs for copper heat exchangers, stainless steel heat exchangers, and
oil coolers can be found on pages 64, 74, and 82 respectively.) Any heat exchanger
that exceeds 56 W/°C at 2 gpm (using a standard fan) would be acceptable. As shown
in the following graph, Lytron’s 6210 exceeds the required performance.
Step 6: Determine the liquid pressure drop
From the data given, we know our pump needs to supply water at 2 gpm. Using the
liquid side pressure drop chart for the 6210 curve, the point where a vertical line at
the 2 gpm point on the x-axis intersects with the 6210 curve reveals that the liquid
pressure drop through the 6210 is 8 psi (0.55 bars). The pump selected must
overcome this pressure drop to ensure a 2 gpm flow.

The vertical line on the thermal performance chart indicates the air flow rate (190 CFM for the Patriot fan) as
provided by our standard fans at 60 Hz. The intersection point of this air flow rate and the 6210 graph on the
air side pressure drop reveals that the air side pressure drop through the 6210 is 0.24 inches of water (55 pascals).

Selecting a Heat Exchanger
2. Cooling Air
In cabinet cooling applications, the air is hotter than the liquid. In this case, the ITD is the difference between
the hot air entering the heat exchanger and the cold liquid entering the heat exchanger. You may need to calculate
the temperature rise using the heat load and the temperature of the cool air entering the cabinet.
Example: Cabinet Cooling application
You are cooling a cabinet containing electronic components that generate 2400 W of heat. The air in the cabinet
must not exceed 55°C. What heat exchanger should be selected, and what is the temperature of the cool air entering
the electronics cabinet?
Step 1: Application Data
Liquid type:
Required heat load (Q):
Temp. of incoming liquid (Tliquid in):
Max. temp of air in cabinet (Tair in):
Rate of liquid flow:
Water
2,400 W (8,189 BTU/Hr)
20°C
55°C (131°F) —— This is the temperature of the hot air entering the heat exchanger
2 gpm (7.6 lpm)
Step 2: Calculate the initial temperature difference
Subtract the temperature of the incoming liquid from the temperature of the incoming air as it enters the heat
exchanger.
ITD = Tair in - Tliquid in = 55°C – 20°C = 35°C (or 131°F – 68°F = 63°F)
Step 3: Calculate the required performance capability (Q/ITD)
Divide the required heat load (Q) by the ITD found above in step 2.
Step 4: Select the appropriate heat exchanger model
Refer to the thermal performance graphs for the heat exchangers selected
(Performance graphs for copper heat exchangers, stainless steel heat exchangers and
oil coolers can be found on pages 64, 74, and 82 respectively.) Any heat exchanger
that exceeds 68.6 W/°C at 2 gpm (using a standard fan) would be acceptable. Using
water as the coolant, a copper heat exchanger is recommended. As shown in the following graph, Lytron’s 6310 exceeds the required performance, offering a Q/ITD of
approx. 96 W/°C using our Caravel fan.
Liquid and air pressure drop can be determined the same way as in the previous
example.

These graphs offer a simple graphical way
of estimating fluid temperature change if you
know your heat load and flow, without having
to do calculations. The graphs for water, air,
50/50 ethylene glycol/water and oil allow you
to calculate temperature changes for air and
liquid for all types of heat exchangers.

Step 5: Calculating the temperature of the cool air entering the cabinet
Now, to calculate the temperature of the cool air entering the cabinet, use the temperature change graph for
air (page 96). With a heat load of 2,400 W, and a flow rate of 250 CFM (the flow rate of the standard Caravel fan
recommended for use with
LPM
the 6310) we can see that the

Step 6: Calculating the outgoing water temperature
To determine the outgoing temperature of the water we use the ‘Water Flow’ chart to find that the change in temperature is approximately 5°C. Therefore the outgoing water temperature is 20°C + 5°C = 25°C.
