Description

The air-handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract. The heat contained in the extract air is recuperated in the high-efficient plate counterflow heat exchanger to warm up supply air. The units are designed for energy efficient ventilation of cottages and flats and are compatible with round air ducts.

Unit design

Casing

Made of high-quality polymer coated steel sandwich, internally filled with 20 mm mineral wool heat- and sound-insulating layer.

Filter

Supply and exhaust airflows are purified through panel filters with filtering class G4. A replaceable filter with filtering class F7 is optionally available.

Fans

High efficient electronically commutated motors with external motor and impeller with backward curved blades. Such motors are the most state-of-the-art energy saving solution. EC motors are featured with high performance and total speed controllable range. High efficiency reaching 90% is the premium advantage of the electronically commutated motors.

Heat exchanger

Counter-flow polystyrene heat exchangers with high heat recovery efficiency. The drain pan under the heat exchanger block ensures condensate removal. In case of freezing danger determined by the temperature sensor, the supply fan is turned off for the period required for the heat exchanger defrosting. The heat exchanger is easily removed for cleaning.

Bypass

The VUT 350 & 550 VB EC units are equipped with a 100 % bypass which can be opened if there is a need to cool down the ventilated area with cool intake air.

Control and automation

The unit includes integrated automation. The heat exchanger freezing protection operates as follows: In case of freezing danger determined by the temperature sensor the supply fan is turned off to let extract air warm up the heat exchanger. After freezing danger is no longer imminent, the unit reverts to the standard operation mode.

Delivery set includes a multifunctional control panel and a 10 m long signaling cable.

Sensor control panel (A14)

The VUT 160 V EC A14, VUT 350 VB A14 and VUT 550 VB EC A14 units are equipped with A14 sensor control panel with LED indication and following functions:

  • Speed selection: Off, Low, Medium or High;
  • Manual opening and closing of the bypass damper;
  • Filter maintenance indication and resetting of the maintenance timer;
  • Fault indication.

The VUT 160 V EC A14, VUT 350 VB A14 and VUT 550 VB EC A14 units can be connected to the PC by means of USB cable. Special software gives following possibilities:

  • Software update of the unit;
  • Adjusting of the Off, Low, Medium or High speed modes from 0 to 100 % for supply and exhaust fans separately;
  • Adjustment of the humidity level and the speed activated by optional humidity sensor HV2;
  • Adjustment of the speed activated by the optional external relay;
  • Adjustment of the temperature of activation of freezing protection;
  • Adjustment of filter maintenance timer;
  • Monitoring of the maintenance timer, humidity level, external relay, and bypass;
  • Error code indication.

PU SENS 01 control panel (A11)

The VUT 160 V EC A11, VUT 350 VB A11 and VUT 550 VB EC A11 units are equipped with touchscreen LCD control panel PU SENS 01 with following functions:

  • Turning unit on/off;
  • Low-medium-high speed selection and adjustment from 0 up to 100% for supply and exhaust fans separately;
  • Manual or automatic opening/closing of the bypass for summer ventilation;
  • Timer;
  • Week scheduled;
  • Actuating external air dampers;
  • Indication, adjustment and maintaining set room or supply air temperature;
  • Control according to the optional duct humidity sensor HV1 feedback or according to the humidity sensor built-in the control panel;
  • Filter clogging control by motor hours;
  • Ventilation system shutdown at signal from the fire alarm system;
  • Cooler connection possibility.
Mounting

The units are designed for the wall mounting. Access for the unit servicing and filter maintenance on the front panel side. During mounting stage, service panel can be installed on the left or right side of the unit along the supply airflow path.
