Range

THERMANNPRO heat pumps

Heat pumps with outputs from 6 kW to 24 kW in 1-phase or 3-phase design.

Basic technology

Full DC smooth (1HZ) inverter technology - inverter heat pump

The heat pump with an inverter works with an adjustable frequency so that it does not turn off after reaching the set temperature, but only reduces the frequency and will continuously maintain the set temperature in the house with less electricity consumption.

The advantage of a heat pump with an inverter is the possibility of installation in colder regions of the Czech Republic. The inverter can automatically adjust the operating frequency when defrosting the unit, it uses high-frequency operation and thus significantly reduces the defrosting time.

In regions with a weaker electrical network or in households with a weaker circuit breaker, the inverter heat pump has another great advantage. When the switch-on command is given, e.g. from the room thermostat, the heat pump compressor starts smoothly thanks to the inverter. In this way, there is no shock load on the electrical network and domestic distribution systems.

LOW-FREQUENCY QUIET OPERATION TECHNOLOGY

An inverter heat pump is less noisy because the compressor runs at lower speeds most of the time and therefore generates less noise. When the set temperature is reached, the units automatically switch to low-frequency mode, reducing their volume to just 43 dB.

DEFROSTING: SPEED AND HIGH EFFICIENCY

The heat pump uses its own patented intelligent defrosting technology. If the frost layer coverage is greater than 85 %, it will switch to deicing mode to ensure rapid deicing.

STABLE OPERATION OF EVI TECHNOLOGY

The compressor uses EVI technology. 20% increasing the refrigerant flow on the one hand expands the operating temperature range from -25 °C to 45 °C and on the other hand realizes two-stage compression, which solves the problem of weak heating effect at very low temperatures such as -25 °C.
