Welded Heat Exchangers

WCR Welded Block Heat Exchanger

WCR Block-Welded Heat Exchanger

Pictured on the right, the WCR Block Welded Heat Exchanger is the latest innovation in welded compact heat exchangers. 

The unit consists of welded corrugated heat transfer plates of stainless steel or other appropriate material. The frame consists of four columns, top and bottom heads and four panels with connections. The totally bolted design allows quick disassembly of the steel frame for easy access to the heart for cleaning, maintenance, repair or replacement.

With no interplate gaskets, problems associated with plate heat exchangers, such as gasket compatibility, temperature and pressure, are eliminated. 

The WCR Block has three plate corrugations: chevron pattern for the most efficient heat transfer, dimple pattern for a 3mm clear gap and aflat pattern for sludge to sludge type applications. The special corrugations result in heat transfer performances similar to the gasketed PHE.

WCR Plate & Shell Heat Exchanger 

WCR Plate and Shell Heat Exchangers are designed for cost effective heat transfer performance and lowest life cycle costs.  The unique bolted version allows quick disassembly of the shell for easy access for cleaning, maintenance, repair or replacement.  The plate joint design and welding are rugged and tested for numerous cyclical conditions. Plate material, absence of gaskets and mechanical/structural design allow for use in many aggressive applications.

Plate & Shell Heat Exchangers can be configured to meet the needs of process requirements in terms of transfer units, pressure drop, design pressures and temperatures as well as piping specifications.

The WCR Plate & Shell Heat Exchanger is compact, with low weight providing an extremely small foot print.
