Compact and wall-mounted, Stokvis’s Econopress Mini pressurisation set can deliver up to 80 l/h at a generated pressure of 2.4 bar.
The Econopress Mini pressurisation set from Stokvis Energy Systems is a compact, wall-mounted unit designed for connecting to heating or cooling installations in small commercial applications or large dwellings. These units house one or two small pressurisation pumps and associated control equipment in a white powder-coated case with a clear flush-mounted pressure gauge on the front to show the system pressure. The cabinet also houses a small make-up tank with its own filling valve assembly, a hydraulic pump capable of producing a pressure from 0.7 to 2.4 bar, pressure control switch, control circuit fuse, terminals and wiring. The self-priming piston pumps can deliver a flow of 80 l/h at a generated pressure of 2.4 bar. The make-up tank has a capacity of 4.5 litres. These sets require a single-phase supply, and lagging is not required between the system and the expansion vessels — reducing installation time and costs. All connections are easily accessible from the bottom of the unit, and the pressure setting can be adjusted by turning a knob on the pressure switch to the desired value, using the pressure gauge as a guide.
