As a manufacturer of professional water coolers, Mistral develops high-performance, sustainable refrigeration technologies that are suitable for intensive use in businesses, local authorities or public buildings.
Among these innovations, the ice bank refrigeration system stands out for its ability to produce cold water continuously, even when in frequent use, while guaranteeing the safety and quality of the water dispensed.
A technology designed for mains-connected water coolers
This system is based on two stainless steel coils immersed in a tank of ice water:
- The first circuit, known as the cooling coil, is connected to the refrigeration compressor. It forms a layer of ice around it, which acts as a thermal reserve.
- The second circuit, the water coil, carries water from the mains supply. As it circulates through the tank, it exchanges heat efficiently with the ice bath to ensure a constant, cool temperature.
These two circuits are completely independent: there is no communication between the refrigerant and the drinking water. An integrated agitator pump limits excessive ice formation and homogenises the temperature in the tank, ensuring constant refrigeration.
Advantages for users
- High cooling capacity thanks to the ice accumulated around the refrigeration coil.
- Stable temperature even at high dispensing rates
- Complete circuit isolation: enhanced health safety, no alteration of the mains water.
- Durable materials designed for intensive use.
- Integrated system as standard in all professional mains water coolers developed by Mistral.
A sustainable manufacturing approach
At Mistral, every innovation is designed to combine performance, eco-responsibility and sustainability. The ice bank is no exception. Its design facilitates maintenance and extends the life of the equipment.
Its design and location facilitate access to internal components, allowing for quick repairs and optimal repairability.
- Simplified access to internal components for quick maintenance and optimal repairability.
- Use of natural refrigerant gases with low environmental impact (R600A or R290).
- Materials selected for their robustness and thermal inertia, guaranteeing stable performance over time.
- Total preservation of the natural properties of drinking water (no alteration of taste, odour or composition).
