Containerized Ice Water Plants (CIWP)

Are water temperatures below +1 °C required, KTI offers Containerized Ice Water Plants (CIWP), which cool down water at an inlet temperature between +20 °C and +45 °C. KTI CIWPs are equipped with a special ice bank systems, which allow the water to circulated around a shell-and-tube evaporator or a plate evaporator.

The ice water systems have a four-stage cooling of the water. First, the water is cooled to +38 °C via a cooling tower or evaporative condenser. Subsequently, further cooling via shell-and-tube evaporators to +4 °C is performed before running through the ice bank system for chilling the water below +1 °C.

Up to a production of 345 m³ ice water per day, the plants are mounted in a 20-ft container, up to a production of 440m³ ice water in a 40-ft. container. The condensing unit is placed on the roof of the container, but can also be integrated as required into the container, which results into a very compact plug-and-play solution.

Of course, the systems can also be built with the same quality on frames for installation in buildings. This enables us to offer our customers individual solutions.

As the perfect complement to the ice water systems, KTI offers perfectly insulated water tanks that are either directly installed in the machine container (ICWT ), installed as a unit into a separate container (CCWT) or in a solid steel frame (SFWT).
