Setting a new standard in Quality and Reliability
ELIMINATE WATER FROM YOUR COMPRESSED AIR SYSTEM
Untreated compressed air is the unseen killer in all compressed air applications.
Premature tool failure, product spoilage, failed instrumentation, damaged
actuators and cylinders, are only part of the long list of casualties in the battle
for increased productivity and profits.
It is all too common that compressed air is the forgotten utility in most facilities.
Without proper treatment, this vital source of work is a wet, gritty, acidic brew,
silently destroying all that it comes into contact with.
In this day and age, clean dry
compressed air is not a luxury. The
MACAIR HX Series of refrigerated
air dryers is the key component
in the ultimate solution for most
applications. The installation of
the right MACAIR HX Series dryer
will show immediate results and
effectively remove gross amounts of
water from compressed air system.
Protection that you need to ensure
the best chance of maximum
productivity, reduced downtime and
enhanced profitability.
HX400-HX625
WHERE WATER COMES FROM?
The atmospheric air entering a compressor intake contains water vapor. To
compress air for industrial use your air compressor typically compresses
approximately 7 cubic feet of ambient air to produce 1 cubic foot of compressed air
at 100 psig. The net result is seven times as much water and contaminates inside
your compressed air lines as outside. If not removed this water and contamination
will mix with hot lubricants forming an acidic substance that will cause premature
failure of your pneumatic tools and equipment, rust, scale and ultimately leaks in
your compressed air pipes.
HOW IS THE WATER REMOVED?
The goal is to lower the dew point temperature in your compressed air system. Dew
point temp is simply the temperature which water vapor changes (condenses) into
liquid water. HX Series air dryers use refrigeration to lower the temperature of the
compressed air, thereby lowering its dew point temp. As the temperature and
dew point drops, the moisture condenses into a liquid and is separated from your
compressed air and drained away. The end result is cool, clean, dry compressed
air ready to work for you and no eliminating damage to your pneumatic equipment.
BUILT FOR YEARS OF TROUBLE FREE SERVICE
MADE IN USA
The MACAIR family of refrigerated compressed air dryers are
handcrafted by dedicated skilled craftsman in the suburbs of Detroit
Michigan USA. MACAIR air dryers provide the user with an integrated
system of high quality components that together make up an air dryer
that will provide years of trouble free service. All components are
sourced from only the best North American suppliers. Years down
the road spare parts will always be readily available from MACAIR
distributors or from HVAC suppliers through out North America. It is
because of this fact and the confidence we have in our craftsman
that we back all MACAIR dryers with a 2 year parts and labor
warranty. When you purchase a MACAIR dryer you will receive the
peace of mind that comes with a high quality MADE IN AMERICA product
backed by one of the best warranty in the industry.
ENERGY EFFICIENT REFRIGERATED AIR DRYERS
HX Series dryers have an average of 2.0 psid pressure drop. Many competitive
dryers have as high as a 5.0 psid pressure drop across there heat exchangers.
High pressure drops causes your air compressor to work harder to overcome
the restriction thereby driving up the consumption and cost of electricity.
Electricity costs accounts for approximately 50% of the air dryers total cost over
the first 5 years of ownership. Every 2 psi of pressure drop across your dryer
will increase your systems electrical costs by 2%. Low pressure drop equals low
electrical costs. Example: A competitors 500 SCFM dryer that has a 5.0 psid
pressure drop will cost over $1098.00 more annually (Based on $0.10 per KW)
in electrical costs versus a MACAIR HX500 dryer with a 2.0 psig.
HX SERIES FIVE STEP DRYING PROCESS
STEP 1. PRECOOLING – Hot saturated compressed air enters the pre-cooler
section of the ADX heat exchanger module and flows thru channels were it
is precooled by out going cold air.The incoming air temperature is reduced
approximately 30F.
STEP 2. EVAPORATOR - The pre-cooled air then
enters the evaporator where it is cooled to its final
dew point.
STEP 3. SEPERATION – The mixture of cold air and
condensation flows into the separation chamber
where is scrubbed by a stainless steel mesh and
the liquid moisture is separated from the air stream.
STEP 4. DRAIN – After the moisture is separated
from the air stream it gathers in a quite zone and is
drained away by the automatic drain valve.
STEP 5. REHEATING – After the air exits the separator
and the moisture is drained away the air stream enters
the reheater where it flows through channels where it is reheated
by the incoming hot air. The outgoing air reheated to approximately
25 to 30F within the incoming air temp and then exits the ADX
heat exchanger module.
HX75-HX150
“It’s whats inside that counts”
HX series dryers are built to withstand the harshest industrial
environments using only the highest quality components and
assembled by highly skilled craftsman. Quality features built into every
HX series dryers.
ADX ALUMINUM HEAT EXCHANGER MODULE
The ADX heat exchanger module combines the air to air
air to refrigerant heat exchangers and moisture separator
all in one compact all aluminum module. Because of the
compact design and no interconnecting piping pressure
drops average 2.0 PSIG, the lowest in the industry.
HOT GAS BYPASS VALVES
Allows dryer to operate at a constant dew point from
0 to 100% load without the possibility of freeze ups.

Energy efficient drains ensure that valuable compressed air is not lost
when condensate is ejected. (optional)
ENERGY EFFICIENT HERMETIC COMPRESSOR
Tecumseh and Copeland Scroll compressors are standard features,
they are Made In The USA , are time proven and are the most widely
used, highest quality compressors available.
OVERSIZED CONDENSERS
Assures proper operation in the harshest industrial environments.
Dryers can withstand up to 140F Inlet air and 120F ambient temps.
