Funke Plate heat exchangers
For more than three decades FUNKE has specialised in the development and manufacture of heat exchangers with up to 2000 m² heat exchanger surface for all current industrial applications and designs.
In the field of Plate Heat Exchangers FUNKE offers a sophisticated range of products able to meet almost any requirement in machine and plant engineering. 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.
Bolted Design (Plate & Flame)
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.

Design / Function
he plate heat exchanger consists of a package 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.
Plate materials - depending on application - are chromium nickel steels, chromium nickel molybdenum steels, titanium and further materials.
