Heat exchanger powers are informed. In the case of your interest and after filling in the technical questionnaire, the best suitable solution will be designed for you.

The program for analysis of heat exchanger powers is available in diskette.

Mantle of heat exchangers is made of carbon steel. Standard surface treatment - base coating.

Designing and manufacturing of atypical heat exchanters and coolers which are made of the materials according to your requests and for various mediums can be offered in addition to type products.
