Brazed Plate Heat Exchanger Integrate Separator Air Dryer GLD120 In HVAC Industry

Air dryer with integrate separator type brazed plate heat exchanger GLD120 as evaporator for refrigeration in HVAC Industry​, such as District heating and locality refrigeration, air conditioning system, ice-storage system, domestic hot water, swimming pool heating , ground souce heat pump system, high-rise buildings pressure blocking , waste heat recovery.

The air dryer with Integrate Separator type brazed plate heat exchanger, this equipment is embedded with a vapor-liquid separation filter based on the brazed plate heat exchanger. So when the air is cooled down to the dew point and gone through the filter, the moisture becomes condensed water and it’s collected by the filter and discharged from the drain. And the air becomes cold and dry out from the exchanger .

As a professional brazed plate heat exchanger supplier and manufacturer,GHE offer customers with quality and competitive BPHE products.

Brazed Plate Heat Exchanger features

The stainless steel plates are brazed together, then no need for gasket and frames.the contact points to help hold the plates together,also can take high pressure.the brazing material function is sealing the stainless steel package.GHE’s brazed heat exchangers are brazed at all contact points,to make sure best heat transfer efficiency and pressure resistance.the advance of brazed plate heat exchanger is compact size and light weight,also can take high preesure up to 4.5Mpa.GHE offers a flexible customer-made design to meet customer-specific requirements then to ensure the most cost-efficient solution for customers’ heat transfer duties.

Brazed Plate Heat Exchanger Material

The BPHE(Brazed Plate Heat Exchanger) main components are stainless steel corrugated plates and copper sheet,the stainless steel plates are brazed together by brazing material (Copper or Nickel)in Vacuum Furnace.Copper brazed heat exchanger can be sued for numerous of applications.however ,for food or application involving aggressive fluids,Nickel brazed units are recommend .

Brazed plate heat exchanger Fluid Flow principle

The basic flow principle in GHE brazed heat exchanger is parallel(except dual system BPHE)and current flow,this design make easier for installation

1) Flow principle in brazed plate heat exchanger Evaporator

In brazed plate heat exchanger,two media flow always in opposite direction,it is called current flow.the two phase refrigerant (vapor+liquid)enters the bottom left of the heat 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.

2) Flow principle in brazed plate heat exchanger Condenser

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

3) Multipass Design brazed plate heat exchanger

The heat exchanger can be designed as a multipass until according to customers’ need.different connections location and type &size.customer specific design are available request.

4) Dual system brazed heat exchanger design

What is dual system?the dual circuit means two refrigerant flows and one water flow.the design is diagonal flow design,that means the brazed plate heat exchanger can be connected with two independent refrigerant circuits.this design can make sure each refrigerant circuit is in contact with the entire water flow.the main advantage is that although when only compressor running still can maximize the water cooling performance .
