Plate Arrangement & Construction
Brazed Heat Exchangers are specially-designed corrugated brazed plates that are used to increase the heat transfer coefficient and lower potential fouling. Standard plate arrangement forms two independent circuits running in alternate layers. The two fluids will flow in opposite directions (counter flow) to further enhance the exchange of heat. Brazed heat exchangers are bonded in a vacuum furnace and helium pressure tested to ensure leak-free performance.
WCR 2C Series - Two Compressor Technology
The 2C series has two independent refrigerant circuits, one on the left side and one on the right-front side of the unit. The fluid connections are on the reverse side for easier access and chiller design. The heat exchanger is based on the principal of having two refrigerants "interlaced" or alternating between the fluid circuits allowing full 100% refrigerant contact with the fluid side. Basically, when only one compressor operates, 100% of the fluid is being chilled (evaporator mode) or heated (condenser mode).  
Brazed Plate Heat Exchanger Advantages

High Efficiency
The embossed pattern of the heat transfer plates promotes high turbulence at low fluid velocities. The high turbulence results in very high heat transfer coefficients.
Compact Size
The WCR brazed heat exchanger can be anywhere from 50% to 80% smaller than other types of heat exchangers. It requires less floor space due to the high thermal efficiency of the stainless steel. The plates are brazed together at high temperatures, allowing the heat exchanger to be compact, leak tight, and rugged.
Close Approach Temperatures
Close-approach temperatures of 1-2°F (0.5-1.0°C) are possible because of true counter flow and high heat transfer efficiency of the plates.  This is an important factor in regeneration and heat recovery processes.
High Temperature and Pressure Ratings
Maximum working pressures from 300 psi to 650 psi, and temperature ratings of 350°F.
