Plate heat exchangers

Areas of use and application

Thanks to their advanced channel geometry and counterflow arrangement, plate heat exchangers enable optimum heat exchange with very low temperature differences between the heat exchange media.

The design options allow cost-effective use for a wide range of media in the fields of cooling, evaporation, and condensation.

The plate heat exchangers are manufactured and tested in accordance with the Pressure Equipment Directive.

On request, acceptance testing can also be carried out by other classification societies.

If required, the plate heat exchangers can be supplied with easy-to-install thermal insulation.

Series with brazed plate pack

The gasketless compact heat exchangers combine the high efficiency of a conventionally gasketed plate heat exchanger with the high temperature and pressure resistance of welded designs. The acid-resistant stainless steel plates are joined together using a vacuum brazing process.

Copper or nickel is used as the brazing material.

The standard types consist of 10 to 200 plates.

The wide range of possible variations (number of plates, embossing, and angle) allows the performance values specified by the operator to be optimally achieved.

The unit is designed for temperatures from -160 °C to +400 °C and operating pressures up to 30 bar.

Series with bolted plate pack

The plates are made of acid-resistant stainless steel, Hastelloy, or titanium.

The one-piece pressed plates are available in sizes ranging from 0.03 m² to 3.25 m².

The plates have a “herringbone embossing” that guarantees turbulent flow and high pressure resistance.

Lateral tensioning bolts clamp the entire plate pack between the fixed frame plate and the movable pressure plate.

The gaskets are made of NBR, EPDM, or Viton. The gaskets can be designed as adhesive or replaceable gaskets.

The use of replaceable gaskets allows for cost-effective gasket replacement.

The gaskets are double-ganged around the channel openings so that a gasket defect is indicated by leakage.

Safety design

Safety heat exchangers with double plates can be used for increased safety requirements. In the event of a defect, the medium flows through the pressureless safety chamber between the double plates.
