Finned Packs

GEOMETRIES
Thermokey’s concept is to satisfy any type of application. A broad array of geometries are therefore available:
- 25x21,65mm with 3/8” or 5/16” tube
- 30x25,98mm with ½” or 3/8” tube
- 50x43,3mm with ½” or 5/8” tube
- 42x36,4mm with ½” or 5/8” tube

FINS
The fins can be supplied in aluminium, copper, tinned copper, prepainted aluminium, double coated or in stainless steel AISI 304; they are provided of spacing rings, these guarantee a perfect fin spacing and contact with the expanded tubes. A special high efficiency corrugated fin is used for a higher performance if compared to normal corrugated fins; a special extra high efficiency louvered fin is also available.

TUBES
The tubes are chosen according the specific use of the heat exchanger and can be in:
- Smooth Copper or internally grooved
- Stainless steel AISI 304

FRAME
The aluminium frame (FeZn, stainless steel AISI 304 and brass are available) is built with an appropriate thickness all around the heat exchanger to assure a perfect protection of the finned pack, the copper bends and the headers.

TESTS AND QUALITY
After the coils have been welded (in inert atmosphere) they are immersed in water to undergo a pressure test with dry air.
The production and quality control specifications are very strict and follow the norm UNI EN ISO 9001:2000, this guarantees each product with its own conformity certificate that comes along with every delivered heat exchanger.
