High reliability

The ERGAS modular commercial heat pump is equipped with multiple failure protection, alternative cycle operation, defrost mode and corrosion protection. These three features ensure reliable and efficient operation, even in demanding commercial environments.

Stable operation even at -25°C

The heat pump is equipped with the innovative EVI (Enhanced Vapour Injection) technology, which allows it to operate efficiently at extremely low temperatures. Thanks to this feature, it can operate efficiently at ambient temperatures as low as -25°C. This makes it suitable for a variety of commercial applications such as hotels, hospitals and industrial buildings where heating is required in harsh winter conditions.

DC inverter

The heat pump optimises energy consumption, resulting in significant cost savings. In addition, the quick start function ensures fast operation, reducing waiting times for hot water or space heating. This increases user comfort and improves overall efficiency.

Water temperature up to max. 75°C

Two great features: intelligent climate control to automatically set the water temperature and a higher water temperature of up to 75°C.
Smart climate curve technology allows the heat pump to automatically adjust the water temperature to the ambient conditions, optimising comfort and energy efficiency.

R290 environmentally friendly refrigerant

A notable feature of the heat pump is that it uses R290 refrigerant, which has a low global warming potential (GWP). With a GWP of only 3, it has a significantly lower impact on climate change compared to conventional refrigerants.

Extremely quiet

Multiple quiet modes allow users to control the sound emitted by heat pumps in a variety of ways. Whether it's to ensure the comfort of guests in a hotel room or to minimise disruption to the working environment, the heat pump allows you to choose the noise level that suits your individual needs.
