Piling on the pressure
December 1st 2006 Stokvis Energy Systems has added the Econpress PU131 and PU151 units, which offer 3 and 5 Bar respectively, to its range of fully automatic and selfcontained pressurisation units. The units maintain the required system pressure in a closed loop heating or chilled water system. The single-pump, chassismounted units incorporate a single-phase, 240V bronze pump, pressure switch, pressure regulating valve, a four-gallon polypropylene break tank, and a base formed of mild steel, zincplated and treated to reduce the chemical reactivity of its surface.
