Single Plate

Since the first commercially successful design was introduced by APV's founder Dr Richard Seligman in 1923, the plate heat exchanger has become one of the most versatile and cost-effective methods for the indirect heating and cooling of fluids.

The basic concept is to run fluids on either side of a thin metal plate so that heat may be transferred between the two fluids.

Product range

APV heat exchanger plates come in over 34 different corrugation patterns and 60 different sizes, so that the heat exchanger can be matched to a particular duty. The largest frame can accommodate up to 1000 plates, giving a heat transfer area of more than 3500 m2 in a single heat exchanger. The plates are typically 0.4-0.6 mm thick.

Features/benefits

• The PHE occupies far less floor space and weighs much less than a tubular exchanger for the same application.
• The smaller size means reduced capital outlay for stainless steel, titanium or other costly metals.
• The ease of disassembly and reassembly facilitates cleaning and can make downtime for this purpose minimal. Up to 97% heat recovery can be achieved.
• Low liquid hold-up avoids thermal breakdown of heat sensitive liquids.
• The turbulent flow reduces fouling and sedimentary deposits to an absolute minimum.
• Plates with different but compatible geometry can be alternated to regulate heat transfer to meet precise process demands.
• The number of plates in a frame may be increased or reduced, and plate flow patterns (i.e. thermally long or short) can be varied to meet changed process requirements.
