Design and Functions of Plate Heat Exchanger
The heart of a PHE is a pack of embossed plates with apertures. The plates are assembled in a 180° angle to each other, resulting in flow gaps on each side. Each plate is provided with a gasket, which securely seals the flow gaps from the atmosphere and separates the two media used in the heat exchange.

The gasketed plate pack is mounted in a rack and is compressed with tightening bolts between the fixed plate and the movable plate. To guarantee maximum heat transfer, warm and cold media are normally fed through the PHE in one-pass or multi-pass counter flow.

Connections are on the fixed plate, but can also be on the movable plate for multipass flow.

Plates Materials
Funke heat transfer plates are always produced in 1.4401 / AISI 316 as this material is generally more corrosion –resistant and more resistant to chloride damage than 1.4301/AISI 304. Depending on the design, Titanium is also available in serial production.
As an option, the following additional material may be used:
  • 1.4301/AISI 304 (cost-effective in the case of uncritical media)
  • 1.4539/AISI 904L (with high nickel content against stress corrosion cracking, good price/performance ratio in the case of media with the low acid and chloride content).
  • 1.4529/254 SMO (higher chloride and acid - resistance than 1.4401/ AISI 316)
  • Hastelloy (highly resistant against acids and chlorides, e.g. for concentrated sulphuric acid)
  • Titanium ASTM B 265
  • Titanium - Palladium (highest material quantity, suitable e.g. for chlorides at higher temperatures)
Gaskets Materials
All gaskets are installed twice in the entry and exit area, creating a safety room which is open to the outside. It prevents the two media from mixing if the gasket leaks.

Depending on the design and the type, adhesive or nonadhesive (clip-system) gasket may be used. As sealing material, we use well known and tried and tested materials such as:
  • NBR (nitrile-butadiene rubber): Universal use for aqueous and unctuous media e.g. water/ oil applications.
  • EPDM (ethylene-propylene rubber): Wide range of applications for many chemical compounds which do not contain mineral oil and grease, and for water-and steam application
  • Flororubber (viton): Extremely resistant to chemicals and organics solvents as well as sulphuric acid and vegetable oil at high temperatures.
Technical Advancement of Plate & Gasket
Gasketpalte plate Heat Exchanger
  • Very high heat transfer rates due to thermodynamically optimized design.
  • Corrugation fields with "Off-Set" embossing allow for symmetrical and asymmetrical flow gaps (1).
  • Specially embossed entry fields for an optimum distribution of media (2).
  • Gaskets fastened by "Clip-system" for easy maintenance.
  • Gaskets have a special ribbed surface, enabling more exact centering and stabilization of the entire plate pack (3).
  • Double gasket with leakage groove between two media, preventing mixing of the media (4).
  • Special plate profile at the edges, reinforcing the plate pack and ensuring high pressure resistance of the gasket during operation (5).

Advantages:

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.
