Plain tube heat exchangers
The hygienic, cleanable alternative to finned tube heat exchangers - with heating surface density on finned-tube level.
- Far fewer deposit points for dust, germs, soot or bacteria
- Every tube can be cleaned directly from outside with a steam lance
- Heating surface density similar to finned tube heat exchangers thanks to small tube diameters
- Modular design also for large volume flows
- Casings available in gas-tight design
Flat coil heat exchangers are plain tube heat exchangers in stainless steel, manufactured from meander-bent tubes. AWS-Technik has developed several types for different fields of application.
High heating surface density without fins
By using small tube diameters we achieve a heating surface density similar to that of finned tube heat exchangers - without their cleaning drawbacks. The modular design makes this type suitable even for large volume flows. Casings can be supplied in gas-tight design.
An economical alternative
Thanks to our efficient manufacturing technology, plain tube heat exchangers are also an economically attractive alternative to stainless steel finned tube heat exchangers.
Frequently asked questions
What is the advantage over finned tube heat exchangers?
Finned tubes offer many corners where dust, germs, soot or bacteria accumulate - after the second tube row, cleaning is almost impossible. Plain tube heat exchangers have far fewer deposit points, and every tube can be cleaned directly from outside with a steam lance if required.
Are plain tube heat exchangers suitable for large volume flows?
Yes. The modular design makes this heat exchanger type suitable even for large volume flows.
Are gas-tight designs available?
Yes, casings can be supplied in gas-tight design on request.
