Description

EcoAir OHRU series of products are designed for fresh air.

But, they can SAVE ENERGY during this process.

 

HEAT RECUPERATOR

All 5 sizes of OHRU incorporate EUROVENT certified aluminum plate heat recuperators. The efficiencies vary for each size, but will be approximately within the ranges from 50% to 70%. Efficiencies may rise up to 80% for high temperature and humid applications such as swimming pools, changing rooms or similar. Recuperators are available with epoxy coating for coastal and swimming pool applications.

ELECTRIC HEATER, WATER COIL OR DIRECT EXPANSION COIL AT HEATING / COOLING (OPTION)

In order to achieve best IAQ, heating and/or cooling coils are available as per order.There are several options available including electric heater or pre-heating, water coil for heating and cooling as well newest design with integrated DX coils for cooling only or heat pump (reversible).

 

BYPASS DAMPER (OPTION)

A Bypass Damper can be fitted inside the unit in order to bypass the supply air. The damper is option with a 240 volts on/off actuator (24 volts option) for summer or winter control. Further controls are available for the damper to provide ‘free cooling’.

FANS

All fans are direct drive powered and specially selected for efficient operation. All of the fans used for the OHRU series are ideal for speed regulation and a full range of matched speed controllers are available.On all models, fans are wired to externally mounted isolators.

MOTORS

Fan motors are totally enclosed and suitable for speed control. All fans are with built in anti-vibration mountings, but in accordance with best practice, we still recommend the use of anti vibration mounts and flexible connections.

PANELS

Panels are 1 mm thickness  with internal acoustic/thermal mineral fiber insulation.The skin is made of galvanized sheet metal.

FILTERS

Standard supply and exhaust air filters are EU4 (G4) grade according to EN 779 disposable pleated panel. Manometers are available as an option. Higher efficiency filters EU5, EU6 or other are available as option also.

“PLUG AND PLAY” INSTALLATION
