Plate Heat Exchangers utilize corrugated plates stacked between a fixed and a movable pressure plate. The corrugation patterns alternate for maximum operating pressures. 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.
The unique corrugation pattern pressed onto each Schmidt-Bretten thermal plate produces the highest overall heat transfer rate by assuring highly turbulent flow and excellent fluid distribution across the entire surface. With high heat transfer rates and true counter current flow, API Plate Heat Exchangers economically handle close temperature approach requirements.
API Heat Transfer's line of Schmidt-Bretten Plate Heat Exchangers incorporate superior design features to ensure long term customer satisfaction.

Brazed Plate Heat Exchangers represent the most compact, rugged and cost-effective means of transferring heat in many industrial and refrigerant applications. Built from 316 stainless steel with copper brazing materials, they provide exceptional corrosion resistance. The SB-Series features corrugated plates that produce highly turbulent flow in a true counter-current direction. This results in high efficiency and a very compact heat exchanger design. Due to the smaller size and reduced material content, they can be the most economical heat transfer choice.

Welded Plate Heat Exchangers represent the most compact, rugged and cost-effective means of transferring heat in many industrial applications. Built entirely from 316 stainless steel, they provide exceptional corrosion resistance. The exchanger features corrugated plates that produce highly turbulent flow in a true counter-current direction. The result is high efficiency in a very compact design. Due to the smaller size and reduced material content, welded plate heat exchangers can be the most economical heat transfer choice.
The standard design has all piping connections located on one end of the heat exchangers. This simplifies installation and maintenance costs. Many times, the piping alone is all that is required to adequately support the heat exchanger, thus eliminating support considerations and labor costs in packaged equipment.
API welded plate heat exchangers have narrow flow channels and reduced liquid volume needs. Due to their efficiency, they can be selected to use less coolant.
The exchanger design features plates with computer-designed corrugations in a "chevron pattern" that is alternated from plate to plate. The plates are then bonded together at their contact points. This yields a strong, unitized construction. Gaskets common to other technologies are eliminated.
The unique capabilities of the API welded plate heat exchanger makes it suitable for a wide range of applications that extend beyond refrigeration including:
API Heat Transfer Semi-Welded plates feature plates that are welded using advanced laser welding techniques. Two plates are welded together and are fitted with a VitonĀ® O-Ring and/or TeflonĀ® gasket liner. The resulting plate pack has every other plate fully serviceable, while maintaining integrity of the welded plate pair.
This is especially suitable for critical fluids and gases, such as ammonia or caustic process chemicals where fluid loss is not acceptable. In the case of ammonia refrigeration, the reduced volume results in significant savings.
