  • Free high-temperature engine jacket and exhaust waste recovery available (as much as 800,000 Btu/hr in the form of 230°F hot water is available per engine)
  • Ultra-high efficiencies (Integrated Part Load Value IPLV COP of 2.6), highest of any available gas chillers
  • R-134a refrigerant
  • Sturdy single-screw balanced action compressor
  • Footprint comparable to an electric chiller’s
  • Microprocessor-based controls, with Modbus compatibility and remote monitoring capability

Water-Cooled Engine-Driven Chillers

Our TECOCHILL “STx Series” and “DTx Series” product lines offer water-cooled engine-driven chillers, ranging from 150 to 400 tons of cooling capacity. Each natural gas engine drives a variable-speed single-screw rotary compressor, connected to a standard vapor compression refrigeration system utilizing environmentally-friendly HFC-134a refrigerant.

TECOCHILL’s “STx Series” models feature a single driveline (one engine) to provide up to 200 tons of capacity, whereas TECOCHILL’s “DTx Series” models use dual drivelines (two engines) to provide up to 400 tons of cooling capacity.

Water-Cooled Engine-Driven Chillers

Industry Leading Technology

All of our TECOCHILL systems use reliable time tested designs to deliver consistent cooling powered by affordable and abundant natural gas - reducing operating costs by 30-60% when compared to conventional electric cooling systems.


The most common applications for TECOCHILL chillers are facilities with significant cooling loads and ownership interested in reducing strain on their electrical infrastructure - both day-to-day and during a blackout.


Ultera Emissions Control

Ultera® -ultra-low emissions system reduces the emissions of harmful criterial pollutants (including, CO, NOx, and hydrocarbons) to near-zero fuel-cell equivalent levels - making Ultera-enhanced equipment compliant with the strictest air quality regulations in the country. The Ultera system can be selected for any of our products or purchased as a retrofit for your already existing natural-gas fueled system.
