Applications
- Cooling of autoclaves, mixers, kettles, and double-jacketed tanks
- Vegetable washing
- Cooling of potable city water for food use
- Cooling of various heat exchangers
Principle
The energy required for process cooling is pre-stored in the form of ice before the temperature drop cycle begins.
- Rapid cooling thanks to the ability of stored ice to absorb a high cooling load at the start of the cycle.
- Flexible operation since ice melts on demand, matching the cooling requirements at different stages of the cycle (high at the start, low at the end).
- Continuous production of +1°C water ensured by forming ice around stainless steel tubes, eliminating the risk of ice buildup inside exchangers—a common cause of total refrigeration unit failure with traditional water coolers.
- Independence from the refrigeration unit, as return water temperature and cooling water flow rate are fully decoupled (accepts high return temperatures).
- Energy optimization: cooling production and storage can be shifted to off-peak hours to lower electricity costs or spread consumption.
- Reduced maintenance costs, approximately half that of conventional water coolers on the market.
