VariVAT is our new next generation smart snap chilling system,  delivering a low-cost effective long-term alternative to the refrigerant circuit on farm.

VariVAT, is uniquely setup to have high heat transfer performance through the evaporator on the base of bulk milk tanks. This unique step change in cooling technology, allows small to medium sized dairy farms to comply with milk cooling standards WITHOUT the added cost of an extra gasketed plate heat exchanger.   Heat recovery is an option, but is highly recommended.
