API Heat Transfer’s Schmidt® plate heat exchangers are used in district cooling, process industries, and other industrial applications for efficient heat transfer between two fluids. Plate heat exchangers use thin corrugated plates stacked between a fixed plate and a movable pressure plate. As the fluids flow across the surface area of the plates, plate heat exchangers can offer high amounts of effective heat transfer in a relatively-small footprint. It is not uncommon to find that a plate heat exchanger can have the same thermal transfer performance as a shell & tube heat exchanger design that is five times larger.
Schmidt® Design Highlights:
- Unique corrugation pattern pressed onto each plate produces a turbulent flow and excellent fluid distribution across the entire surface, thus achieving a high heat transfer rate.
- True counter current flow and high heat transfer rate allows the plate heat exchanger 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, and any leak is vented to atmosphere for ease of detection.
- 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.
- Easy to expand for greater capacities as a facility grows.
- Available in a variety of plate sizes for industrial, HVAC, power, or food industry applications.
