Sol-Tech srl Solution Technology offers two kinds of air cooler models:

  • “Power line” Dry Coolers
  • “Power J” Dry Coolers



“Power line” is a range of air coolers featuring various fin geometries, with differentiated pipe diameters and special fins, a range of different modules, appropriate fans and innovative materials and design. The combination of all these factors of the “Power line” series entails the following advantages:

  • Maximum capacity related to the cooler dimensions
  • Optimized primary fluid pressure drops thanks to the use of various tube diameters.
  • Possibility of an optimized product selection by using different module lengths.
  • Compliance with the strictest environmental standards in terms of acoustic pollution

The “Power line” Dry Coolers are thus a very innovative product capable of fully satisfying the requirements of anyone operating in the industrial cooling sector.

In this range of air coolers one can has a choice of using fans of 4 different diameters: 500, 630, 800 and 900 mm; the number varies from 1 to 16 fans, in a single or double row for capacities of between 8.5 kW and 1,120 kW at normal standard conditions(ENV 1048 standard).

Double speed external use fans are used (400V/3ph/50Hz), to achieve up to 8 sound levels for each diameter.

The casing is made of zinc coated steel, stove enamelled with polyurethane resins (RAL 7035 standard) to ensure the equipment’s utmost solidity and robustness.

On request, for this air coolers series, the following accessories are also available:

  • Phase cut, voltage step and inverter speed controllers
  • Standard electrical boxes and special versions on request
  • Fins in various materials (aluminium, copper and aluminium, pre-coated and double coated).
  • Copper tubes and, for special uses, stainless steel AISI 304 tubes or even aluminium
  • Special motors: single phase for 500 and 630 mm diameters, 60Hz net frequency, various voltages and for high ambient temperatures.



“Power J” is a series of innovative double coil air coolers capable of fully satisfying the requirements of industrial refrigeration and air-conditioning operators.

The capacities of the new Power-J series range from 76 kW to 1,585 kW at normal conditions (ENV 1048 Standard).

The extraordinary performance of these dry coolers is the result of an optimal combination of new high efficiency aluminium fins with copper tubes and newly designed fans which can develop high air flow with reduced current absorption and low sound emissions.

The Power-J series is based on a modular design with a RAL 7035 stove enamelled galvanized steel casing and can assemble up to sixteen 900 mm fans with 8 sound power levels, in a single or double row.

On request, for this air cooler series, the following customized arrangements are also available:

  • Phase cut, voltage step and inverter speed controllers
  • Standard electrical boxes and special versions on request
  • Special materials for all types of uses or installation environment.
  • Very low energy consumption electronic motors.

An innovative “adiabatic” AFS (Air Fresh System) system is also available on request: this automatic cooling system enables the cooler to keep up the same level of performance even when the environmental air temperature is higher than design conditions.
