The chilled water unit is a cold production solution. It will produce chilled water using air or water calories and a refrigerant. Chilled water will then flow through pipes to supply ice-water dispensers (such as convection ventilators, air treatment plants, etc.).
There are many benefits from using a chilled water unit at your events: it is less hazardous than handling refrigerants; it offers freeze protection (with glycoled water); it allows for greater control accuracy and is reversible.
Your event will be a real success with the ambient temperature you wish.
