EXTENDED OPERATION RANGE HEATING MODE

Tlw

At low ambient + high leaving water temperature, the liquid injection prevents the compressor from getting too hot due to high discharge temperature.

New in this model is an electronic expansion valve with optimized injection quantity.

Avoid too high discharge temp by low liquid injection

HOT GAS PASS

Improved resistance at colder Tambient: hot gas pass

Hot gas pass in bottom plate to keep the temperature of the bottom plate positive. All drain holes are open so drain can get out of the unit

Additional sealing at the bottom of the heat exchanger to reduce the cooling by airflow

Before the refrigerant pipe is split up by the distributer to the hairpins, the pipe passes through the bottom of the coil.
