CUPER D125 supply-exhaust heat recovery unit, 6 speeds, ERA

CUPER heat recovery unit is designed to provide forced ventilation in rooms and premises with a heat recovery technology.

The device ensures fresh air supply at a comfortable temperature in every season. Heat recovery is done with a ceramic heat exchanger which controls the temperature of the supplied air making it comfortable.

The heat exchanger gets heated or cooled during the exhaust process. Then it heats or cools down the supplied air (depending on the temperature outside). E.g. in winter, when the heat recovery unit works in an exhaust mode, exhaust air heats the ceramic heat exchanger. Then, when being turned to a supply mode, the device also heats cold fresh air up to a comfortable temperature. In summer the working process is reverse. The supplied air is already a bit cooled down when it enters the room eliminating the necessity for ventilation. So, these processes reduce expenses for heating or conditioning. CUPER also filters the air cleaning it from dust, pollen and other small particles which may cause an allergy.

Working temperatures: outdoor temperature is from -30 to +50°С indoor temperature is from +1 to +40°С

The heat recovery unit is operated by a remote control. Has 4 working modes:

• supply mode
• exhaust mode
• alternating supply-exhaust mode
• smart mode

Smart mode depends on the outdoor temperature. The cooler or warmer the air is outside (as compared to the indoor air temperature) the less intensive the exhaust process is. Supply-exhaust intensity control is done with special temperature sensors.

Also supports the automatic mode: when being activated, the device works in a supply mode and then switches to exhaust. The modes alternate in the time preset (60, 70, 80, or 90 sec).
