Acma HP 4900 Four Seasons has a high efficiency rotary compressor that produces 4.5 times the energy input. The technology is based on renewable energy from the outdoor air and recycle energy from the building's ventilation air.

There is no outdoor unit which allows energy passes through the machine and reused. This provides a proper saving of annual consumption for heating.

Heat is distributed throughout the house and re-used all the time, all year round, even on cold winter days. Acma is ideal in combination with wood stove, fireplace or wood stove as it reuses the energy again and again but always in the new fresh air. Spent air leaving the unit minus degree.
