Heat recovery in laboratories and research
MKW 700 Laboratory heat recovery with heat exchanger
Efficient:
The compact heat recovery unit, type MKW, is a chemically resistant cross-flow heat exchanger that utilises the contaminated warm laboratory exhaust air from fume cupboards and hazardous substance cabinets to heat the incoming outside air.
The fully-fledged supply air system, including the control cabinet, integrated into the compact housing with the heat exchanger, replaces the extracted contaminated air with 100% heated fresh air. Thanks to the achieved efficiency of over 60%, a small built-in reheater is sufficient to compensate for the temperature difference.
Ready to go:
The heat exchanger with integrated supply air system is wired ready to plug in and ready for use. Once the supply and exhaust air ducts have been mechanically connected and the unit has been electrically connected to a 230V socket, the switch contact of the compact unit is controlled in parallel with the on-site exhaust fan. This is usually done via the switch-on contact of the exhaust air monitoring system. When the exhaust air monitoring system is switched on, the heat exchanger with integrated supply air system starts automatically.
Flexible:
- Exhaust/supply air heat recovery for laboratories and schools
