Replacement Copper Brazed Heat Exchanger with Double Circuit Solution Evaporator​

Replacement Copper Brazed Plate Type Heat Exchanger with Double Circuit Solution Evaporator​

Evaporator flow principle

The channels formed between the corrugated plates and corners are arranged so that the two media flow

through alternate channels, always in opposite directions (counter current flow). The two phase refrigerant

(vapor + liquid) enters the bottom left of the exchanger with a vapor quality depending on the operating

condition of the plant. Evaporation of the liquid phase takes place inside the channels and some degrees of

superheat are always requested, which is the reason why the process is called "dry expansion". In the enclosed

evaporator picture the dark and light blue arrows show the location of the refrigerant connections. The water

(brine) to be cooled flows counter current in the opposite channel; the dark and light red arrows show the

location of the water (brine) connections.

Standard design

The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. The channel

plates are corrugated to improve heat transfer efficiency and to make them rigid.

Standard materials

Cover plates: Stainless steel AISI 316

Connections: Stainless steel AISI 316

Plates: Stainless steel AISI 316

Brazing material: Copper

Advantages of brazed plate heat exchangers in Industry and HVAC&R

The Baode Brazed plate heat exchangers (BHE) have several advantages over traditional heat exchangers in Industrial

and HVAC&R applications.

– The high heat transfer efficiency of the BHE makes it extremely compact and also easy to install in places were space

is limited.

– The unit has no gaskets and is therefore suitable in applications were temperature and/or pressure is high e.g. in district

heating.

– The Baode supply system reassures that, no matter were you are on the globe, the BHE units are available with a very

short delivery time.
