Can also be used with contaminated air
The air supply and exhaust air flow is not mixed with this system. Hence, contaminatedprocess waste heat can also be used without problems.F7 filters are installed in the outdoor air intake, and M5 filters are installed in the exhaustair. For aerosol-polluted air, optionally, an upstream metal mesh filter in the exhaust aircan prevent contamination of the ventilation system REKU and simultaneously protectthe environment.
The decentralised Ventilation system REKU is equipped with a plastic or aluminium heat exchanger (recuperator). With this innovative heat recovery, of the air extracted from your indoor hall, up to 84% is recovered as precious energy.
Through this, post-heating of the extracted outside air is only minimally required. This protects the finite resources and your wallet.
The amortisation of the Ventilation system REKU is thus reached quickly.
The demand for air is provided via direct drive EC fans. For reheating the incoming air supply, a pumped warm water damper register or an electric heating register can be used as desired.
Draught and dust-free air distribution
The distribution of the air supply occurs via a thermally controlled diffuser unit or channel system or a textile air guidance system.
For summer operation, the ventilation system is equipped with a bypass control. In this case, the heat recovery is bypassed and ventilated unheated. An additional heating of the fresh air is thus excluded.
For air conditioning, a corresponding register can be fed with cold water or refrigerant (evaporation process). A cold water pump or a heat pump serves as the refrigerating unit. This results in a constant and pleasant hall temperature.
Adjustment of air flow
In the standard version, the system runs on two programmable levels of ventilation. Optionally, the air flow can be controlled as needed. Thus, the operating point is automatically changed according to temperature, humidity or CO2 content. Furthermore, remote control via LAN connection is possible.
The ventilation systems REKU significantly exceed the required 70% (based on the efficiency) as stipulated in the Renewable Energy Heat Act (EEWärmeG).
Decentralised installation on the roof or on the wall
The ventilation system REKU is set on the roof with a crane and bolted together within its onsite manufactured supporting structure. The ventilation system can also be installed on the side wall. On the roof, maintenance and filter replacement is easy through inspection doors.
Areas of application
The ventilation system REKU is suitable for ventilation of industrial and commercial halls, as well as for operations where constant air exchange is necessary for production-related reasons.
