InvenSor LTC 09

The InvenSor LTC 09 is the optimal solution for efficient heat-driven cooling at lower temperatures.

Depending on the application, this equipment reaches its full efficiency at temperatures as low as approximately 65°C, a level at which other thermal chillers typically only offer very limited performance or cannot yet function. It is therefore particularly suitable for being operated with CHP units, district heating networks and thermal solar installations in temperate climates. The InvenSor LTC 09 is suitable for outside temperatures of up to approximately 35°C. For higher temperatures, we recommend the InvenSor HTC range.




Simple installation and commissioning

The slim construction facilitates transport in buildings. The housing is optimised for transport using lift trucks and transport dollies. To simplify hydraulic connection even after the machine has been set up, all the connections are located on the back of the machine at the top offering good access.

Parallel connection possible

Higher cooling capacities can be easily achieved by connecting a number of modules in parallel. Owing to the automatic optimisation of the operating point, the efficiency of the machine typically increases in the event of part load operation.

Can be used as a heat pump

Operation as a heat pump has already been prepared and can be activated on the equipment. As in cooling mode, drive energy also has to be available on the hot side. Geothermal or solar heat can be connected on the cooling side. The desired low-temperature heat consumer is connected to the re-cooling circuit. This gives rise to efficiencies of up to approximately 150% relative to the thermal energy employed.
