Get to know more
Our cooling media is water. The quality of water needed is determined by the specific application:
Pure water - when water with low conductivity is needed
Power electronic applications such as:
- Cooling of semiconductors in electrical devices such as HVDC, SVC, converters, drives etc.
- Cooling in metallurgic processes and other industry applications.
- Cooling where pure water without chemicals is essential, for applications such as food and medical industry.
- Cooling of magnetic coils such as generators and motors.
Tap water - when conductivity is no issue
- Room cooling
- Energy storage
Glycol/water mixture - when there is a risk for freezing
How it works
The principle of all pure-water cooling systems is fundamentally the same. There is a main loop cooling the object. Water transfers the heat to water-to-water or water-to-air heat exchangers. From the main loop a small part of the flow passes a water-processing circuit. The water is filtered mechanically. If necessary, it is also continuously purified from ions and oxygen. The conductivity of the cooling water can be maintained as low as <0.1µS/cm (at 25°C).
Our cooling systems are prefabricated and assembled in one or several units. Most of the systems include control equipment with PLC and software. The systems are tested and verified before delivery.
Installation and start up
As we deliver systems globally, we have developed design standards and control routines for efficient onsite installation and start up. Most of our customers can easily set up the systems themselves by following our manuals.
Container Cooling Solutions
As an option the systems can be delivered as a ready-to use container solution. This can be used to optimize logistics, minimize outage time and installation time.
In a regular container solution the cooling system pump unit, treatment circuit, motor starters as well as the protection and system control are mounted into an enclosure or container. Optional equipment for the container may include insulation, ventilation, lighting, heating and air conditioning.
