The Pedrollo TISSEL TS2-5CR 200 is a compact, high-performance automatic pressurisation system with inverter, suitable for use across residential and commercial applications. The system consists of a multistage pump coupled with an electronic inverter and external pressure sensor. The TISSEL pump maintains a constant pressure through continuous variable adjustment of the speed of the pump. The inverter protects the pump against dry-running, short-circuit and over-pressure or under-pressure. Variable speed adjustment of the pump achieves a lower overall life cycle cost through maximum energy savings and minimum pump wear.
