KTI Ice Water Chiller Plants (CIWP)

KTI Ice Water Chiller Plants serve as the basis for cooling concrete. Since water is always used in the production of concrete, it must be cooled as deeply as possible. Likewise, KTI Ice Water Chiller Plants are used in water cooling, also called hydrocooling. Here, cold water of almost 0°C quickly extracts heat from the concrete.

Plant information

A KTI Ice Water Chiller Plants is equipped with a special ice water pool . The system consists of a water tank in which a plate or coil heat exchanger is installed. Ice can form around this heat exchanger without destroying the system by volumetric expansion due to freezing of water. The water circulates around these heat exchangers, which are slightly covered with ice. In this way the water temperature is between 0°C and 1°C. Only in this way can the low temperatures be achieved without the water freezing.

The ice water systems will be in 20-foot or 40-foot ISO containers turnkey preinstalled. This depends on the required capacity, which is available from 60 m³ to 450 m³ of ice water per day.
The most common fresh water temperatures are +20°C in temperate climates, +30°C in hot regions and +45°C in tropical areas.

Your advantages of KTI ice water plants

KTI Ice Water Chiller Plants are the most energy-efficient models on the market.
KTI Ice Water Chiller Plants produce ice water with Temperatures close to 0°C.
KTI Ice Water Chiller Plants are equipped with a separate ice water pool .
KTI Ice Water Chiller Plants cool water even with very high inlet temperatures from 45°C .
KTI Ice Water Chiller Plants come preinstalled and are taken very quickly in operation .

Greatest efficiency through multi-stage cooling

KTI Ice Water Chiller Plants are the most efficient systems on the market. By cooling the water in several stages to almost 0°C, it is possible to optimum operating points can be achieved. The components therefore run on a energy-optimized point. This not only protects the material, but in particular raises the Potential for energy savingg. This is what distinguishes KTI Ice Water Chiller Plants from commercially available equipment.

Ice storage as thermal storage

The ice water basin, which is installed in KTI ice water plants, can also be used as ice storage. Here, electrical energy can be stored in the form of thermal energy. be stored easily and inexpensively. While the electrical energy is available, ice builds up around the cooling coils. If only little electrical energy is available, the ice can be broken down and thus water can continue to be cooled.

Expert knowledge

Our ice water systems have been reliably in use since the end of the 1980s. Planning an installation for concrete cooling always starts with cooling water as close to 0 °C as possible. The ice water can then be added directly to the concrete mixer and also used for the efficient production of ice. It would not make technical and economic sense to work with hot water here and at the same time to cool at another place.
