STRATE AWAaerob

Pre-fabricated STRATE AWASTATION service buildings are set up directly on top of shafts (STRATE AWALIFTSCHACHT) or optionally alongside shafts on concrete foundation blocks. Pre-fabricated solutions offer the possibility of housing system components e.g. shaft cabinets, control elements, electric systems and service connection so that they are easily accessible integrating further optional system components e.g. STRATE AWAaerob ventilation systems, operating data recording and remote transmission etc. One-piece pre-fabricated concrete building, suitable for road and crane transport with four threaded attachment and transport sleeves Re-siting of the service building is possible Inside walls: exposed concrete, painted with washable dispersion paint, colour according to customer wishes Outside walls: textured render, painted in colour according to customer wishes Floor: smooth concrete floor plate with openings for shaft cover, cable duct etc.

AVUSE-1 for degassing under pressure, AVUSE-3 for degassing, high flow rate air inlet and outlet. Simple but studied design – To reach the best performances with optimized components. Ventilation area protected – From splashes and clogging thanks to a specific deflector design, ensuring a long term operation. Polymeric high-quality material. Easy maintenance – Thanks to quick removal of the clamps and drainage cock.

The BEV-G is a single-stage valve offering only the function of the first ventilation stage (coarse ventilation) provided by the two-stage valve (BEV-GF). It is not necessary to coordinate the valve to the working pressure in the first ventilation stage, since coarse ventilation is always closed under pressure. Type G (coarse ventilation): The air escapes through this valve until the medium closes it as it continues to flow. The valve remains closed under operating pressure. Ventilation of individual sections in sloped pressure lines, especially as a low pressure safety feature Quick ventilation of high points if fine ventilation is not required (short pump run times)

The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities. Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again. Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required. Installed at high points of pressure lines with low flow quantities.
