Does your home or property suffer from condensation, mildew, or black mould? Do some rooms, especially bedrooms, smell musty or damp? As homes become increasingly airtight, controlled ventilation is needed to provide a healthy safe and energy efficient living space. A highly efficient fan combined with a hexagonal cell recuperative heat exchanger provides ventilation with highly efficient heat recovery. Up to 97% of the energy used to heat your room can be recovered using the Kers unit.

The unit has built in humidity control to remove the conditions for black mould growth. The built in ambient noise reduction reduces street noise in urban situations. Kers units provide ventilation without the need to open windows giving the added benefit of increased security. Kers units can be networked to provide a whole house ventilation solution with minimal disruption during installation.

Ventilation is the key to condensation problems. Unfortunately, just leaving a window open doesn’t allow enough ventilation into your home. Our Ventilation Systems will provide solutions to condensation, mildew, and poor air quality problems in both new and existing properties. KERS Ventilations systems are designed for both private houses and apartments or flats where homeowners experience the many symptoms of poor ventilation.

The innovative design of the KERS Evo ventilator has hexagonal cells, with increased exchange surface and better thermal efficiency: up to 97% heat recovery. The KERS Evo heat recovery unit can be installed almost anywhere. It is sufficient to make
a hole in the outside wall with a diameter of 160mm for KERS Evo 50 and 100mm for KERS Evo 25 and bring the 230v power supply to the unit.

KERS Evo 25 is ideal for controlled mechanical ventilation for rooms up to about 10 square meters for each device, KERS Evo 50 for rooms up to about 20 square meters. For larger rooms, simply mount multiple devices per room.

The device extracts exhaust air from the room for 65 seconds, the airflow goes through the ceramic core, and it heats it up. The ceramic core stores the heat for the next phase: The fan changes direction and the fresh air coming from outside goes through the same ceramic core. The core heats up the air with the previously stored energy. The result: fresh air coming from outside, at almost same indoor temperature. The same process works in summer too, so KERS saves energy all-year around. KERS needs less electrical power than a LED light bulb. KERS is a high-efficiency heat recovery device, specifically designed to be installed as a room-by-room heat recovery ventilation system.

KERS boasts a highly efficient ceramic recovery core that enables it to attain a heat recovery efficiency up to 97%. When KERS is installed in each room, it will improve the overall energy performance of the building and its energy class. The flow rate is up to 50 m3/h, that means that KERS can change the air quickly and silently, but without any energy waste. In winter the ventilation of KERS keeps humidity in check and thus prevents or solves the problem of mold formation in the corners of the rooms.

KERS EVO has two on-board buttons to turn the unit on and off and comes complete with remote control. KERS Evo doesn’t require unsightly wall switches or regulators, or the associated wiring. Numerous functions available: free cooling, ventilation only, ventilation with recovery, activation based on humidity, night mode. KERS does not require any switchboard or control box to be placed in the wall, dispensing with the related masonry and wiring work.
