A single-room heating appliance is a heating appliance which serves to heat the room in which it is placed or installed. Heating appliances, chimneys

Supply ventilation units serve to supply indoor spaces with filtered and possibly preheated outside air. Exhaust ventilation units serve to remove exhaust air from indoor spaces. Ventilation

Ventilation units with heat recovery serve to supply and remove air from indoor spaces while transferring the residual heat from the exhaust air to the supply air via a heat exchanger. Ventilation

In timber construction, screws are used to permanently connect timber elements to other elements or to reinforce timber elements. In this work area, you will also find threaded rods and screws for ext

Systems for treating stormwater run-off containing mineral oil serve to purify run-off from motor vehicle traffic areas to such an extent that the effluent may subsequently be infiltrated into the gro

Systems for limiting hydrocarbons in mineral oil containing wastewater with biodiesel, bio heating oil and ethanol contents are systems for treating wastewater containing up to 100% biodiesel and bio
