Modine Greenhouse Heating
Modine’s Breakthrough
Greenhouse Heating
Solution
Greenhouse Heating Applications
 Greenhouse Heating Costs are a Key Issue to Growers
– 2nd highest cost after labor
– A matter of survival in lean years
 Greenhouse Heating is Both a Comfort & Process Issue
– Occupant health & comfort
– Crop health and yield
 Greenhouse Environments Present Challenges
– “Tight” Construction - Traps humidity & chemicals inside
• Humidity
– Molds and Fungus
– Equipment Corrosion
• Chemical Vapors
– Forms acids when combined with moisture & heat
Gas-Fired Unit Heaters
Why Gas-Fired Unit Heaters Make Sense
 Warm, Forced-Air Heat is Healthy For Plants
– Uniform heat = Uniform growth
– Absorbs moisture and mitigates mold & fungus
– Helps plants absorb CO2 more efficiently
 Vented Furnaces Remove Harmful Flue Products
– Water vapor
– Ethylene, harmful to many plants
– Carbon monoxide, causes discomfort, sickness
or death for occupants
 Individually Piped, Wired & Vented for
Redundancy
– If one unit fails, the others work overtime
– Less risk of no-heat situations
Gas-Fired Unit Heaters
Why Gas-Fired Unit Heaters Make
“Cents”
 Zone Control
– Units only run where heat is needed
• “Off” is the highest efficiency
 Re-Cycles Heat Stratifying at the Ceiling
– Heat from solar radiation
 Quick Reaction from Night Setback Temps
– Boiler systems require longer “warm-ups”
 Low Installed Cost
– Comparatively low equipment cost
• No mechanical rooms, pumps, valves, etc.

Modine Has Supported the Horticultural Industry for Decades
 Historically Designed Solutions to Meet Growers’ Changing Needs
Gravity Vented GFUH - Provide low cost reliable heat; 1960s – 1990s
• 65% efficient however
Power Vented GFUH - Provide more reliable installations as houses
became “tighter” with more efficient coverings; 1980s – 2000s
• 78% efficiency
Separated Combustion GFUH - Provide longer life expectancies in
tighter houses that also had more chemical usages; 1980s – today
• 80% efficiency
- 93% efficient, separated combustion,
condensing GFUH; provides highest efficiency and
longevity
The Next Leap Forward
Modine’s NEW Effinity93 – 93% efficient separated combustion
condensing unit heater with our exclusive Conservicore technology

Effinity93 Design Features
AL29-4C Secondary
Heat Exchanger
The Heart and Soul…
 Secondary heat exchanger made of AL29-4C
stainless steel
– Robust material designed specifically to
withstand acidic condensate (PH 4)
 Lowers the flue temperatures from 350-400
degrees F to 110-120 degrees F
Condensate Production
– Approx. 1+ gallons/hr for small units
– Approx. 2+ gallons/hr for large units
– Need to drain both unit & vent system

Effinity93 Benefits
What this means for the grower
 19% Fuel Savings Over 80% Efficient Power Vented
Units
 43% Fuel Savings Over Natural Draft Gravity Vented
Units!!!
– 65% Seasonal Efficiency Due to Open Vent Heat
Losses
 May qualify for local utility rebates & tax incentive
programs
 Improved standing with Big Box customers
 Separated combustion advantages
– Provides sufficient air to unit for combustion
– Longer lasting heat exchangers, burners & controls
– Day-to-day operation enhanced with controls with
in casing
Effinity93 Benefits
Comparatively What This Means to the
Grower
 All advantages of GFUH apply
– Warm air circulation, vented flue products,
redundancy, heat de-stratification, low
installed costs, etc.
 Direct-fired efficiencies without direct-fired
disadvantages
– Water vapor, ethylene, carbon monoxide,
required air changes
 Boiler efficiencies without boiler system
disadvantages
– High up-front costs, mechanical rooms, piping
system complexity, no redundancy, lower
water temperatures, fuel storage (biomass)
