Chilling in the production of
  • Chemicals
  • Pharmaceuticals
Application and benefit
  • Storage of refrigeration capacity in ice
  • Increasing of peak cooling power with smaller refrigeration machine
  • Limiting peaks in electricity consumption
  • Advantage of using low night tariffs for electricity


The benefit of an ice storage unit is the increased cooling power for peak loads while using smaller refrigeration machines, which have to be designed for the average demand only.

The cost efficiency is based on the utilization of low night tariffs, which sometimes cost half the money, or on limiting the max electricity peaks, which reduces the basic price of electricity.

Method of operation

Storage or building ice: Evaporator panels are placed upright in a rectangular water tank. Ice is build at an evaporation temperature between -4 and -10 °C, depending on the storage time. The ice sticks to the evaporator panels. (static ice bank) For ammonia systems, a separate suction pipe at the evaporator ensures the oil return.

Cooling phase or thawing phase: On the tank floor there is a distribution system for the warmer return water to ensure a homogeneous thawing of the ice. Additionally there is a distribution system for the air agitation, which provides intensive turbulence to ensure a perfect heat transfer and low ice water temperatures. The air agitation starts up automatically when required only. A maximum of cooling power is ensured at lowest ice water temperatures due to a nearly constant ice surface up to the very end of the cooling phase.
