A.H.U. unit with heat recovery, VUT V EC mini version

A.H.U. unit with heat recovery, VUT V EC mini version

Manufactured from aluminum-zinc compound with 20 mm thick mineral cotton layer for heat and sound insulation

Two incorporated G4 panel filters for extract and supply air filtration are applied in the unit.

The impeller with backward curved blades are powered by high-efficient electronically commutated (EC) direct current motors. As of today the ventilation systems based on heat exchangers are the most state-of-the-art and progressive solution for air exchange organization in the premises. EC motors are featured with the high efficiency and perfect control over the whole speed range. Premium efficiency (reaching 90%) is an absolute advantage of electronically commutated motors.

Heat exchanger
The cross-flow air-to-air plate heat exchanger block is manufactured from aluminum plates. Whenever heat recovery is not required the heat exchanger block can be easily replaced by a “summer” block. The unit is also equipped with the drain pan for condensate drainage as well as built-in icing protecting system. Its operating principle is based on switching the supply fan off as per the temperature sensor. Warm exhaust air heats the heat exchanger. Then the supply fan switches on and the unit continues operating under normal rated conditions.

The unit is controlled by means of external control signal 0-10 V (e.g., R-1/010 controller for ЕС-motors). Air capacity as a function of temperature level, pressure and smoke conditions and other system parameters. Should the value of the control factor get changed the EC-motor changes its speed and the fan boosts as much air volume to the ventilation system as required.

Air handling unit is mounted on the floor and suspended to the ceiling by means of a seat angle with inserted vibration-damping element or attached to a wall with brackets. The unit can be installed either in service spaces as balcony, storeroom, basement, roof space or in main premises above a suspended ceiling, in the pocket or the unit can be placed directly in the room. Mounting in any position shall provide correct condensate drainage. Access for the maintenance shall be reserved at the side of the swing-out access cover.
