HEAT EXCHANGERS

EXCHANGER VT2 - PVL (steam – water, horizontal), VVL (water – water, horizontal)

The exchanger types labelled as VT2 – PVL and VVL are produced for casing/insert pressure 1.6/1.6 MPa, and maximum casing/insert working temperature 200/200°C. The heating medium (i.e. steam or water) enters the exchanger’s casing and transmits the heat to the water being heated by means of insert consisting of U-shaped Cu/Fe tubes. For HSW production, a reverse connection is applied due to clogging by scales. The exchangers are placed on mounting foots. Each exchanger can be dismounted and the insert replaced. 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.
