Power line Dry Coolers

THERMOKEY presents a new series of liquid coolers (dry coolers) called “POWER-LINE” featuring various fin geometries in different modules using new materials and a new design. This newly born product, which is the result of Thermokey’s years of experience, is able of fully satisfying the needs of the industrial cooling sector. The combination of three factors such as fin geometry (differentiated tube diameters and special fins), proper fans and differentiated modules enable to achieve the following:

- Maximum capacity related to the heat exchanger dimensions.
- Optimized primary fluid pressure drops thanks to the use of various tube diameters within the dry cooler series.
- Possibility of an optimized product selection by using different module lengths.
- Respect of the most strict environmental norms in terms of acoustic pollution.


The declared capacities and sound pressure levels are according to the ENV1048 norm. 4 different fan diameters are used : 500, 630, 800 and 900 mm.; from 1 to 16 fans in single or double rows for capacities from 8,5 kW to 1120 kW at normal nominal conditions. In order to achieve the maximum strength of the unit, the casing is manufactured in oven-painted galvanized steel and polyurethane resins (RAL 7035). External use double speed 400/3/50 Hz fans are used to obtain 8 different sound pressure levels for each fan diameter.

A complete series of accessories are available upon request. Among these are:

- Phase cut, voltage step and inverter speed controllers.
- Standard electrical boxes and special versions on request.
- Custom made special or standard wiring-junction boxes.
- Fins in various materials (Aluminuim, Copper, Epoxy or Double Coated).
- Copper tubes or stainless steel AISI 304 tubes for special uses.
- Special fans: single phase fans with 500 and 630 mm diameters, 60Hz net frequency, various voltages and fans for high ambient temperatures.
