Plate Heat Exchanger

Plate-Heat-Exchange

Plate heat exchangers are used wherever thermal energy (heat) has to be transferred from one fluid to another.

The advantage is that they can maintain the fluid temperature at a very low and stable level – depending on the temperature of the coolant.

Plate heat exchangers consist of a stack of stamped heat exchange plates which are either brazed together or bolted together in a frame with gaskets. Medium flows in the channels between the plates where the hot medium (which will be cooled) alternates with cold medium (which will be heated). The design of the plates induces the turbulent fl ow required for efficient heat transfer.

Brazed plate heat exchangers – HYDAC HEX Sxxx

The design and construction of the brazed plate heat exchangers are particularly compact and efficient. The heat transfer plates are made of stainless steel and are brazed with copper as standard. For use with aggressive media, nickel braze can also be used.
Copper brazed plate heat exchangers are pressure resistant up to 30 bar, nickel brazed up to 10 bar. Special models are however also suitable for higher pressures.

Gasketed plate heat exchangers – Hxxx-LIQUID

Gasketed plate heat exchangers are particularly suitable for large flows and high cooling capacities. The stack of heat transfer plates and gaskets is clamped together with bolts in a frame.
This means that the plate heat exchanger can also be dismantled for cleaning and maintenance. Furthermore, it is possible to add more plates at a later date to achieve a higher capacity.
For applications with seawater, the plate heat exchangers can also be supplied with titanium heat transfer plates. Various stamp designs can cater for heavily contaminated or high viscosity fluids to suit particular applications, or even if the temperature difference between the hot and cold medium is only minimal.
Safety heat exchangers with double-walled plates are used in situations where different media must be strictly isolated.
