The AG Series of Air Conditioners and Desiccant Regenerators accurately control humidity and temperature of an air-stream using a liquid desiccant and external sources of 130°F and 60°F water. They are designed to condition outside air in all climates, especially those that are hot and humid, to comfort conditions (see below).
The AirGreen products run on supplies of hot (130°F) and chilled (60°F) water to handle the regeneration and cooling loads. The water flows are controlled according to the total gross cooling (enthalpy) load on the machine and have approximately 95% effectiveness.
The AirGreen system comprises an Air Conditioner and a Regenerator. Each unit receives the energy supply by chilled and hot water, similar to an AHU.

"Buy American Act"
The 60°F Revolution: With the ability to use chilled water a high as 60°F, the AirGreen unit allows, for the first time, direct use of geothermal water.
The 130°F Revolution: With the ability to use regeneration hot water as low as 130°F, the AirGreen unit enables the use of electric heat pumps for both cooling and heating in the AirGreen process. Also, for the first time, low temperature waste energy that is recovered from other processes/equipment can be utilized for additional savings.
The Net Cooling Revolution / Breakthrough: Unlike most desiccant systems, the patented AirGreen multi-stage process produces supply air at 60°F and below. This allows AirGreen units to be a direct replacement for RTUs and AHUs in many applications. In other applications AirGreen units may be added to pre-treat the outside air.

The AG 2000 is differentiated from conventional equipment because it:
Wter to Water heat pump
To obtain water supplies from VRF systems and refrigerant heat recovery
From recommended Geothermal installers to meet AirGreen's specs.
From Solar Thermal installers with mixing valve for over-temperature protection.
