barra per lavaggio di gallerie stradali BLT GR 01 municipaltech

The BLTGR tunnel washer spray bar is a high-pressure spray bar completely in AISI 304 stainless steel, in tube-shaped frame, especially designed in order to allow the transfer/passage/flow of water at extremely high pressures, still preserving an excellent structural mechanical resistance. The tunnel spray bars can be designed according to the customer’s specific needs and can be equipped with ball joints/junctions to close the ending parts, useful during the transport of the equipment. The opening and closing procedures can be managed by means of hydraulic cylinders or electrical actuators (12/24 V). The rotary movement of the special rotary nozzles together with the pressure given by the water pump (installed on the back module) guarantee an optimal cleaning on any kind of wall/surface.
