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.

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).
