InvenSor HTC 18 plus

Compact solution for efficient thermal cooling at high outside temperatures

The adsorption chiller InvenSor HTC 18 plus with an integrated hydraulic unit is especially easy to install. It can be used efficiently with dry recoolers at ouside temperatures of up to 40°C and reaches its optimal capacity at driving temperatures from 85°C. For operation at lower driving temperatures, the InvenSor LTC machines are available.

Cooling capacity 18 kW

The nominal capacity of the HTC 18 plus is 18 kW. For an easy installation, all hydraulic connections are conveniently accessible on the top side of the machine. The unit is optimized for transport by pallet jack. The compact design allows for space saving set-up.

Easy operation and setting – prepared for heat pump operation

The setting of the target water temperatures in the chilled water circuit, the driving circuit return flow and the recooling circuit is easily adjustable on the multi-color, multi-lingual touch display at the front of the machine. The heat pump mode is already installed and can be activated easily.

Maintenance-free cold water production by ActiVac

ActiVac is an InvenSor development for optimizing the operating pressure in the adsorber. Pressure control, otherwise needed in sorption chillers, becomes obsolete.

Integrated Hydraulic unit

The HTC 18 plus is integrated with all basic components for thermal cooling. It includes a complete hydraulic unit with three electronically regulated high-efficiency pumps, so that all necessary water circuit pipes for heat supply, cold distribution and recooling can be connected directly to the chiller.

Free cooling function

The free cooling function allows for even more energy savings: If the outside air temperature is cold enough, it can be used directly for climatization and no driving heat is necessary to operate the chiller.
