Service Box HP

Safe. Reliable. Simplified Maintenance.

Municipal digesters operate with biogas pressure higher than industrial or agricultural digesters. This allows for simpler biogas management without biogas booster blowers. The Service Box High Pressure (HP) has been specifically designed to meet the higher biogas pressure demanded at your municipal wastewater treatment plant. This Service Box is custom designed for municipal applications thanks to the corrosion resistant AISI 316 stainless steel construction, an integrated gas lock system to eliminate gas leakage during maintenance and Cl I, Div. 1 approved motors and cover plates.

With the Service Box HP, the operation of mixers is greatly simplified. Adjusting the position and the height of the mixer can be done from outside the tank, thanks to the proven winch positioning system. This allows for optimized tank mixing and confidence that your complete tank volume is utilized. General mixer maintenance can be completed on the Service Box HP platform thanks to the removable access covers on the floor and the front. All of this is possible without biogas release or draining the tank. As a result, there is minimal or no impact on the biological process. That saves money and, of course, valuable time.
