SWT/C
FrymaKoruma Scraped Surface Heat Exchanger Frytherm, Type SWT/C
The compact and user-
friendly scraped-
surface heat exchanger guarantees efficient heat exchange, especially
for high-
viscosity products.
Key Advantages
- Modest space requirement due to compact design
- Drastic reduction in energy consumption
- Better heat transfer coefficient thanks to mechanical mixing
- Significant reduction in heating and cooling times
- Easy to clean and service
- Suitable for in-line CIP
- Rapid return on investment
- Controlled heat exchange
This series consists of 4machine sizes.

Functional Description
The Frytherm has several tubular product chambers, which are adjoined on both sides by similarly tubular fluid chambers.
The product which must be heated or cooled is moved through the product chambers in the axial direction. Rotating scraper
arms, which brush over the full contact surfaces of the product/fluid chambers, plunge into the product chamber. They generate
a strong turbulence in the product and continuously remove the product film that forms on the heat exchange surface. This
ensures an efficient and controlled heat exchange.
The inlet and outlet are arranged such that the product entering the Frytherm displaces all the air inside it. The mechanical
seal seals the product chambers off from the surrounding atmosphere. This ensure that the product does not absorb any air
inside the Frytherm.
Both product and media chambers are pressure proof to 4 bar (or 8 bar as an option).
