Heat / Coolth Recovery

In Heat Recovery mode, the unit will utilise the heat in the extracted air to warm the incoming air, via the integral high efficiency heat / coolth exchanger block, to increase the incoming external supply air to as close as possible to the desired temperature for the space or room. In Coolth Recovery mode, the unit will utilise the coolth in the extracted air to reduce the incoming air temperature via the heat / coolth exchanger block when desirable. Only when it is beneficial to do so, will the unit’s heat / coolth exchanger block bypass facility be activated.

Improved dual condensate tray

Condensate will be dealt with on both sides of the high efficiency heat /coolth exchanger block via two separate drain points which can be connected together on site and taken to a single drainage point. This twin condensate drainage arrangement prevents unit internal air leakage and the possible undesirable accumulation of condensate as can happen in other units with single drainage points.

Key Benefits

Efficient Fans & Motors

All units have a free running, high performance backward curved impeller and special three-dimensional blade geometry that provides reduced rotational tone. The EC fans within the units are the most efficient in converting electrical power input into air power, resulting in low energy consumption and significant economic benefits for the end user.

Counterflow Heat Exchanger

Thermal energy exchange is enhanced by the large surface area of the heat exchanger resulting in high efficiency rates of thermal energy recovery. All units are fitted with a 100% face and bypass damper. The bypass damper operates
dependent on temperature parameters and values set via LCD display to offer free heating mode in winter.

Lightweight & Slimline

Smallest and lightest energy recovery units available on the market. Despite their compact size, which helps to reduce building and maintenance costs, the units have a strong, solid construction with reduced environmental footprint and enhanced acoustic performance.

Integrated Demand Control

The standard control system provides effective monitoring and targeting of energy consumption with the possibility of individual room control through integration with Building Management Systems.

Casing Air Leakage Rated at: L2

Low risk of mixing filtered with non-filtered air and minimised infiltration of non-handling air inside the AHU.

Finer Particulate Filters

The F7 supply filter and M5 extract filter improve Indoor Air Quality by always providing filtered, fresh and healthy air.

Compliance

ErP 2018 ready and fully compliant with Ecodesign Directive 1253/2014.

Quiet

Peaceful performance for a comfortable indoor environment.

Schools & Offices

school ventilation

Failure to correct poor indoor air quality within an educational or working environment can lead to increased illness and absences, and reduced cognitive function. An energy recovery unit helps to maintain comfortable working temperatures by recovering thermal energy from the already warm air inside the occupied space to raise the temperature of the incoming fresh air. F7 filters are fitted in the unit to remove pollutants and provide pure, clean, fresh air that encourages concentration and productivity.

Restaurants, Hotels & Leisure Centres

healthy air

In building spaces with a high volume of guests and visitors, maintaining a comfortable and healthy indoor environment without increasing energy bills, can prove to be a challenge. The energy recovery units maintain good indoor air quality and comfortable temperature levels by efficiently transferring thermal energy from the stale air to the incoming fresh air, to effectively maintain good indoor air quality.
