All AAON Products feature R410a refrigerant options including packaged roof top units, air cooled chillers, evaporatively cooled chillers, condensing units, and water cooled/WSHP products.

A modulating scroll compressor that allows for unloading to 10% is applied to the lead circuit to provide incredible part load comfort, humidity control, and low energy costs.

AAON's patented design provides unprecedented energy savings, water savings, low maintenance and simplified installation.

AAON's unique design for an integrated energy recovery wheel (not a separate bolt on accessory) offers high efficiency, single point power, and compact footprint.

ABB's ACH550 VFD provides for quality modulating control of fans, pumps, and cooling towers. ABB's compact design makes retrofit of these drive very easy to accomplish on existing structures.

The IPC 11550 controller uses Hartman LOOP control methodologies on "all variable speed" to provide an annualized central plant efficiency of .50 kw/ton, the best by 20% of any other central plant control methodology.

Packaged central plants including centrifugal chillers, pumps, cooling towers and integrated controls provide for high efficiency controls and equipment and the lowest total carbon footprint of any chiller plant.

Work with our team to optimize mechanical room layouts using the latest in Solidworks 3D design software and innovative space saving equipment.

Insulated tubing on Ultrasorb dispersion units eliminates the heat rise associated with humidifiers and decreases the amount of condensate and improves system efficiency.

Since 1979, the ENVIRO-TEC brand has been an industry leader for innovative design and superior performance. Our complete line of airside products for the commercial HVAC industry includes Variable Air Volume (VAV) terminals and controls, fan coil units, and indoor air handlers.

Combines pulse technology, centrifugal separation, and mineralization to provide total treatment of condenser water and industrial heat transfer systems. Decrease water blowdown and increase cycles of concentration.

Coils of refrigerant filled tubes provide pre-cool and re-heat to an evaporator coil via natural refrigerant migration properties. No moving parts.

Passive Sensible heat transfer of exhaust and supply air streams for energy savings. No moving parts.

Remove system solids using centrifugal separation and keep heat exchange surfaces from fouling. Purge system solids with zero water loss via the SRV.

98% Efficient condensing boilers in the Hi-Delta and MVB (coming soon) copper finned tube boilers.

Inverter compressor and fan technology applied to condensing units and air handlers to provide very high efficiencies at very low total installed costs. Very quiet operation..

Provide cooling with low amounts of inducted air. Minimal fan horsepower required.

Revolution units provide dehumidification without the need for over-cooling and reheating.

Total and sensible energy recovery wheels provide 3 Angstrom dessicants and highest efficiency in the industry.

ASHRAE Innovation Award Winner in 2004. Provides the highest efficiency centrifugal on the market, inherently variable, oil free, lowest sound, low turndown, and compact.

Highest efficiency geothermal unit on the market. EER's up to 30+, R410a refrigerant, Desuperheater option, and two-stage unit option.
