Absorption Chiller powered by Natural Gas


For hot climate cooling.


  • Extremely low electricity consumption: saving up to 88% of electricity compared to a traditional electrical system, no additional energy, no modification of electrical cabin.
  • Single Phase Power.
  • Smaller Generator Requirements for applications requiring off grid power or emergency cooling.
  • Complete system flexibility and modularity to increase the Seasonal Performance Factor: multiple links available (RTCF TK, HT and LB units).
  • High reliability due to few moving parts inside the units.
  • Easy Maintenance, similar to gas fired boilers.
  • No Water Consumption. No cooling tower and related water treatment and maintenance.
  • No Use of Harmful Refrigerants that contaminate the environment.
  • Outdoor Installation. No need for indoor equipment room.


Air conditioning for residential, commercial and industrial applications, with external air temperatures up to 131°F.
