The EER Max® applies the cool building exhaust air through an evaporative process using air conditioning produced pure condensate water to the refrigerant condensing cycle to improve A/C system capacities and efficiencies by as much as 50% or more. A standard EER unit takes the building exhaust air and reclaims only a maximum of 65% of the exhaust air’s energy back into the A/C system (at a 15% make-up air requirement this would result in a total system increase in capacity and efficiency of only approximately a net 10%).  The EER Max® is therefore 5 times the capacity and efficiency gain of a standard EER unit.

This is absolutely not true and is based on a lack of knowledge of legislation that protects the consumer from frivolous warranty voidances by manufacturers. The primary legislation regarding this issue is known as the “Magnuson-Moss Warranty Act.”

A product is deemed “green” when there is a carbon dioxide reducing energy savings that reduces dependence on fossil fuel.  In fact, because of the increased efficiency of the EER Max®, it reduces CO₂ production by an average of over 5 to 7 tons per year for a typical 10 ton roof top package air conditioning unit.  The 5 to 7 tons of CO₂ saved is equal to the CO₂ emission for a car that consumes 500 to 700 gallons of gas per year.

The EER Max® is engineered for a very low refrigerant friction related pressure loss and the line sizes are engineered for low friction related line loss as well, so that the benefits of the EER Max® are not offset by any friction related operational problems, even when the EER Max® is not operating while the A/C system is operating.

When a HVACR system has a high friction related pressure loss (too small a refrigerant line size for example), even though a pressure drop is seen at the liquid line port, the pressure seen by the compressor is actually higher, while reducing pressure due to better heat transfer actually results in a lower pressure at the outlet of the compressor.  Lower head pressure at the outlet of the compressor results in increased efficiency, whereas increased head pressure at the outlet of the compressor results in decreased efficiency.

City or well water can be utilized ONLY if run through a reverse osmosis water purifying system.  If utilized straight or even through any other kind of water treatment system, damage to the EER Max® can occur.

Yes, but the increase in efficiency and capacity will not be as high as with building exhaust air.

When a system produces more capacity, the run time requirement of a system decreases, resulting in the A/C system being off more of the time.

No, because the increased capacity comes with an increase in dehumidification of roughly 35% due to a unique reduction in flash gas loss in the evaporator due to the increased sub-cooling of the refrigerant. This results in an average colder evaporator coil, which in turn results in better dehumidification.

Every degree of sub-cooling results in an increase of system capacity of approximately 1¼%.  This is one of the primary reasons why water cooled (or geothermal) systems are so much more efficient than air cooled systems.

Rapid de-superheating of the refrigerant by means of water cooling results in a lower condensing head pressure and a cooler operating compressor.  Lower head pressure results in lower power consumption by the compressor, and a lower compressor operating temperature results in a longer operating life expectancy for the compressor.  This is another reason why water cooled (or geothermal) systems are so much more efficient than air cooled systems.
