Plate Heat Exchanger

The plate heat exchanger uses a series of corrugated metal plates assembled with NBR or EPDM gaskets to transfer heat between two fluids. The specially designed plate channels create strong turbulence as fluids pass through the heat exchanger, improving heat transfer efficiency and reducing the risk of fouling.

The high-performance plate structure provides excellent thermal performance within a compact footprint. Its detachable design also simplifies inspection, cleaning, and maintenance, and is suitable for a wide range of heating and cooling systems.

IES plate heat exchangers are assembled with a series of heat transfer plates separated by gaskets, which create independent channels for hot and cold fluids. The plate pack is compressed within a rigid frame to form parallel flow channels with alternating fluid paths. The movable back plate is secured by tightening threaded rods, keeping the plate pack under proper compression. During operation, the two fluids flow through separate channels on both sides of the heat transfer plates. Heat transfers through the thin plate surface without direct contact between the fluids for an efficient thermal exchange.

Heat Transfer Plates

Technical Advantages

IES detachable plate heat exchangers are available with multiple plate designs to meet different heat transfer requirements. The plate range includes large-angle and small-angle corrugation patterns, as well as shallow groove, deep groove, and ultra-deep groove designs. By combining different plate patterns and channel depths, the heat exchanger can be configured with narrow channels or ultra-wide channels to match different flow conditions and thermal requirements.

We offer a wide selection of plate types and groove depths to create customized plate heat exchanger configurations for different applications. The variety of plate combinations allows better matching between the heat exchanger and actual operating conditions.

A suitable plate configuration helps achieve effective heat transfer performance while reducing equipment cost. It also improves fluid velocity between plates, which helps reduce corrosion and scaling caused by low-flow areas.
