Bare Plate Heat Exchangers
For applications requiring the transfer of heat from one system to another Stokvis have an extensive range of both Bare Plate and Frame gasketed heat exchangers (BPHE) and Compact Brazed heat exchangers (CBE) as well as a full range of fully packaged units to suit.
Gasketed Plate Heat Exchangers provide outstanding efficiency transferring heat from one liquid to another or from steam to liquid. This modular exchanger combines frames, plates and connections to form a variety of configurations. By using different types of plates, with different characteristics, the exchangers can be adapted to a wide variety of applications. The exchangers can easily be disassembled for inspection, maintenance or even expansion by adding plates.
The flow turbulence created by Plate Heat Exchangers promotes maximum heat transfer. The units also offer “U” or “K “ values 3 to 6 times higher than shell & tube exchangers.
With its high efficiency, the Plate Heat Exchanger conserves space and floor loadings far beyond what is possible with an identical duty shell & tube heat exchanger. A Plate Heat Exchanger may have a footprint that is one fifth of a shell & tube’s footprint, including service and maintenance space, making good use of tight spaces, especially important with production expansions. Lighter weight makes transportation and rigging less costly.
The heat exchanger’s velocity profile and induced turbulence causes dirty product deposits to be continually removed from the heat transfer surface during operation, thereby reducing fouling. The plate turbulence also enhances the effectiveness of water back flushing and cleaning in place (CIP) procedures with less frequent need to disassemble the exchanger.
Compact Brazed plate heat Exchangers are one of the most efficient ways to transfer heat. They are designed to provide unparalleled performance with very low life-cycle cost. Choosing brazed technology for heating or cooling projects will bring many benefits, including savings in space, energy, and maintenance. Our CBEs are extremely compact compared with other technologies. The footprint can be as little as one tenth that of a shell & tube heat exchanger.
With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature approaches.
The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance.
The compact size uses space efficiently and makes system design more flexible. Our CBEs are largely self-cleaning, thanks to highly turbulent flows. In applications with a high risk of fouling or scaling, Cleaning in Place (CIP) is easy without disassembly.
