?

Product Description

?

The spiral fin tube economizer is a newly type heat transfer equipment, consisting of spiral fin tubes to overcome the serious abrasion and short service time.Which?consisted?of ?series of spiral finned tubes, the headers of inlet and outlet, bend, frame and other auxiliaries

Structure arrangement: in line/staggered arrangement

?

Features

?

1. The equipment body can be designed into many modules to ensure the long term and stable running.

2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage.

3. Improve the heat transfer efficiency.

4. Structure arrangement: In line or?staggered arrangement.
