DION’s TIP
Dion Rohrer
Product Development Manager
In brazed plate heat exchangers (BPHE) the #1 mode of failure is freezing. Do
not cool water below 33˚ F. In water chiller applications the low pressure cut-out
on the refrigerant side should be set no lower than 28˚ F, based on evaporator
refrigerant pressure at this temperature.
Features
• Easy to install
• Compact size means it ts easily into conned spaces, especially when
replacing a much larger shell-and tube heat exchanger
• High Performance
• High turbulence created by corrugations in the plates results in closer
approach temperatures with much smaller units
• Fully brazed construction handles high operating pressures
• Copper brazed 316L stainless heat transfer plates
• Proven and Reliable
• UL listed and ASME Section VIII available
• Every heat exchanger is tested before it leaves the plant
