HEAT EXCHANGERS

EXCHANGER VT4 – VVL (water – water, horizontal)

The exchanger types labelled as VT3 – PVL and VT4 - VVL are produced for casing/insert pressure of 1.6/1.6 MPa, and maximum casing/insert working temperature 200/200°C. They provide a suitable option for central heating systems. The heating medium (i.e. steam or water) enters the exchanger’s casing. The Cu or Fe tubes are expanded or welded into two fixed tube-plates. Water flows in four directions (i.e. VV) or in two directions (i.e. PV). The exchangers have a neck for input and output of water and steam, and welded-on pieces for a thermometer, settling and venting. The exchangers are coated with primer.
