The exchanger types labelled as VT4 – VVS are produced for casing/insert pressure 1.6/1.6 MPa, and maximum casing/insert working temperature 200/200°C.
The heating medium enters the exchanger’s casing or insert, and transmits the heat by means of straight Cu or Fe tubes that are expanded into two fixed tube-plates. The exchangers have a neck for input and output of water, and welded-on pieces for a thermometer, settling and venting. The exchangers are coated with primer.
Besides the standard products listed in our catalogue, special models can be supplied as well.
