1.5. Brief Description of the Unit
• Casings of air handling units are made of galvanized steel sheets, which are powder painted. Mineral
wool is used for thermal insulation and sound attenuation. Unit cover panels are 45 mm thick.
• The air handling units are intended for ventilation of medium-sized and big-sized spaces (eg. shops,
offices, etc.), having operating ambient temperature and relative humidity. As standard, the unit
is designed for indoor and outdoor (with additional parts) placement. The operating temperature
range for the unit is -30 °C ... 40 °C, outdoor air temperature.
• The air handling unit is not to be used to transport solid particles, even not in areas where there is a
risk of explosive gases.
• VERSO-R is equipped with a rotary heat exc hanger, VERSO-RHP air handling units with a rotary heat
exchanger and a heat pump system, VERSO-P/PCF – with plate heat exchanger, air filters, an electric
or water heater, fans and automation control system, to ensure safe and efficient operation of the
unit.
• Before you open the door, the unit must be switched off and the fans must have been given time to
stop (up to 3 minutes).
• The unit contains heating elements that must not be touched when they are hot.
• To maintain a good indoor climate, comply with regulations and, to avoid condensation damage,
the unit must never be stopped apart from during service/maintenance or in connection with an
accident.
• If the unit is placed in spaces with high humidity, condensation might occur on the surface of the
unit when outdoor temperatures are very low.
• Under conditions, when the outdoor air temperature is low and humidity is high, risk of heat ex-
changer frosting may appear. For this reason anti-frost protection function is foreseen in the control-
ler of the Komfovent air handling units. Depending on the type of the recovery, different methods
