Plate heat exchangers
HRS FUNKE - heat transfer plates are characterised by optimum embossing resulting in high heat transfer coefficients. This permits low-cost and optimum adaption to the respective application conditions. Our product range includes single-pass and multi-pass plate heat exchangers with heat exchange surface up to 2000 m².
In the field of Plate Heat Exchangers HRS FUNKE offers a sophisticated range of products able to meet almost any requirement in machine and plant engineering. HRS FUNKE’s special “off-set” system with asymmetrical flow gaps creates highly efficient and cost-effective apparatuses whose performance (depending on design) is up to 17 percent higher compared with conventional plate heat exchangers.
the “HRS FUNKE” brand stands for highest quality standards and customer-oriented solutions.

The plate heat exchanger consists of a pack with linked up embossed plates with passage openings. Every second plate is staggered by 180°, creating a flow gap at any given time. All plates are provided with tied up or glued gaskets, which completely seal the various flow gaps from the outside and separate the media involved in heat exchange.
The plate package is mounted in a rack and is pressed between fixed plate and pressure plate by means of clamping bolts. During service life the gaskets of a plate heat exchanger are subject to a normal fatigue process and therefore the plate package can be retightened several times - dependent on conditions of use - until "PP"-min. is reached.
Connections of media involved in heat exchange are on the fixed plate, in case of multi-pass flow also on the pressure plate (see basic scheme below).
Special materials:
Plate materials - depending on application - are chromium nickel steels, chromium nickel molybdenum steels, titanium and further materials.
Gasket materials are: NBR, EPDM, Viton, silicone and special materials

Advantages of Plate Heat Exchangers (PHE)
- Low investment, operation and maintenance costs.
- Highly efficient heat transfer (K- values on average 3-5 times higher than in case of bare-tube heat exchangers).
- Asymmetrical flow gap available for the most costeffective solution.
- Use of smallest temperature difference <= 1°C
- Up to 75% less space required.
- Self-cleaning effect due to highly turbulent flow behaviour
- Future additional capacity is possible by fitting extra heat transfer plates
- Double gasket with leak groove gives high safety with regards to media mixing.
- Easy to open/clean
- Low operating weight/ low liquid content.
