Thanks to this complete control, Mistral ensures highly reliable products, always in line with market requirements.
Direct expansion technology is a cooling technique that was originally created for brewers.
It is a solution to have a continuous, very healthy flow.
The distributed water does not come from stagnant water in a refrigeration tank, which eliminates the risk of bacteria proliferation. Thanks to an antimicrobial copper alloy in the form of a coil, the water remains constantly in motion, which limits stagnation and the formation of bio films. This provides some bacterial immunity. Mistral uses direct expansion technology for all of its mains water coolers to guarantee healthy water in all circumstances.
The Ice Bank Refrigeration is a system developed by Mistral allowing a significant production of cold water: the cold coil is covered with a layer of ice which increases the water’s refrigeration capacity by producing a significant cold reserve.
This system is active thanks to two coils (one in stainless steel and one in copper), one dealing with cold and the other with water. They are both immersed in a tank filled with chilled water, which guarantees a greater cold capacity. The two spiral alloys never touch each other, which prevents any communication between the refrigerant gas and the mains water. An internal agitator pump limits the risk of ice formation. Thanks to this system, Mistral guarantees fresh water all day long.
Thanks to an electric control system, the installation is 100% safe after each use thanks to the valve kept closed; no risk of micro-leakage. This Mistral innovation guarantees the security and compliance with standards of all water distribution points. The whole system is CE and ACS certified.
This technology is an ultraviolet lamp disinfection system (guaranteed mercury-free). Thanks to the radiation of the UV rays, the micro-organisms are completely eliminated, leaving a healthy and purified water, free of bacteria. The placement of a quartz crystal just before the dispensing nozzle reflects the UV rays for disinfection from the first to the last drop poured.
