Project Description

BL20 B3-020 B8 Danfoss condenser brazed heat exchanger for heat pump


BES brazed plate heat exchanger is used to exchange heat between two fluids. Brazed plate heat exchanger has the characteristics of high performance, compact structure and light weight. High efficient heat exchange performance reduces the amount of cooling water required for heat transfer, thus reducing the operation cost.

Production feature

– Compact Size and Easy Installation
– Less Cooling Water Required than Shell-and-Tube Heat Exchanger
– Lighter Weight than Shell and Tube Heat Exchanger
– Optimized Fouling Coefficient to Reduce the Cleaning Frequency
– Can Customize Thread as Requirement

Fluid Flow principle in Brazed plate heat exchanger

The basic flow principle in BES brazed heat exchanger is parallel (except dual system BPHE) and current flow, this design can achieve the most efficient heat transfer performance. Normally the connections are located on one side of the heat exchanger, this design make easier for installation.

Flow principle in Evaporator brazed plate heat exchanger

In Brazed plate heat exchanger, the two media flow always in opposite directions, it is called current flow. The two phases refrigerant (vapor + liquid) enters the bottom left of the exchanger with a vapor quality depending on the operating condition of the application. Evaporation of the liquid phase takes place inside the channels and some degrees of superheat are always requested.

Flow principle of Brazed plate condensers

Same components as for the evaporator. The hot gas refrigerant enters at top left of the exchanger and starts to condense on the surface of the channels until fully condensed, sub cooling also requested.

Packing Method: Wooden box or carton box
