SIGMA – GASKETED PLATE HEAT EXCHANGERS

Plate heat exchangers use corrugated plates stacked between a fixed and movable pressure plate. As virtually all of the material is used for heat transfer, plate heat exchangers can have large amounts of effective heat transfer surface in a small footprint. It is not uncommon that a plate heat exchanger will have the same thermal capacity as a shell and tube five times larger. Our plate heat exchangers incorporate superior design features to ensure long-term performance and customer satisfaction.

PERFORMANCE NOTES

• Unique corrugation pattern pressed onto each plate produces the highest overall heat transfer rate by assuring turbulent flow and excellent fluid distribution across the entire surface
• True counter current flow and high heat transfer rate allows our plate heat exchangers to economically handle close temperature approach requirements
• Highest quality gaskets precisely fit the plate grooves for positive sealing and ease of maintenance
• Superior clip-on gasket design ensures proper fit during closing of the unit
• Double sealing design prevents the possibility of mixing the two process fluids; leak detect feature ensures any leakage is to the atmosphere
• Zinc coated hardware provides long life
• All bolted construction for easier service
• Low volumetric fluid hold-up provides quicker response to heating and cooling demands, while reducing costs for more expensive process fluids
• Readily expanded for greater capacities, or totally new applications
• Available in a variety of plate sizes for industrial, HVAC, power, or food industry applications
