Vents VUT 300-1 G EC is an air handling unit without a heater. To heat the air, a heat recuperator is used, which heats the supply air from the heat of the air removed from the apartment. The installation uses energy-efficient fans with EC electric motors. The power consumption of the installation is only140 Wwith fairly good performance up to300 m3/hand good fan pressure up to400 Pa.
The unit body is made of aluminum profile and sandwich panels with internal heat and sound insulation made of 25 mm thick mineral wool.
Filter
To filter the supply and exhaust air, the unit has two built-in filters with a cleaning degree G4 (exhaust) and F7 (supply).
Motor
Uses high-efficiency external rotor electronically commutated (EC) DC motors equipped with a double-suction impeller with forward-curved blades. Such motors are by far the most advanced solution in the field of energy saving. EC motors are characterized by high performance and optimal control over the entire speed range. The undoubted advantage of an electronically commutated motor is its high efficiency (up to 90%).
Fans
The Vents VUT 300-1 G EC unit is equipped with supply and exhaust centrifugal double-intake fans with forward-curved blades and a built-in protection thermostat with automatic restart. Electric motors and impellers are dynamically balanced in two planes. Rolling ball bearings of electric motors do not require maintenance; their service life is at least 40,000 hours.
Recuperator
The counter-flow recuperator is made of polystyrene plates. For operation of the unit without recuperation, a “summer” liner is provided. Under the recuperator block there is a tray for collecting and discharging condensate. The supply and exhaust unit is equipped with a built-in system for protecting the recuperator from freezing during the cold season. Its essence is that the temperature sensor turns off the supply fan and the warm exhaust air warms up the recuperator. Then the supply fan is turned on, and the entire installation operates in normal mode.
Control
VUT H EC is equipped with a speed controller A2 ( R-1/010). In this case, the installation is controlled using a 0-10 V signal.
