The recuperative evaporator, ReVap, is a pioneering new evaporation system designed to literally vaporize evaporation costs and reduce glycol refrigeration expenses in the process. By for the first time combining the two processes of evaporating excess CO2 and refrigerating glycol, ReVap reduces the energy costs associated with both processes.

Essentially an innovative heat exchange system, ReVap uses the cooling capacity of stored liquid CO2 to chill glycol. The transfer of heat between glycol and liquid CO2 subsequently raises the temperature of CO2 to its evaporation point and the compound is expelled as a gas.

Since this simple concept relies solely on the efficient reuse of existing resources, it is estimated that ReVap offers a saving equivalent to about 43% of a brewery’s total annual production costs. And a unit typically pays for itself within 18 months.

As a self-contained system ReVap is installed quickly (within 48 hours) without the need to halt production, and its straightforward design makes it virtually maintenance free.

If you are looking to shrink energy bills - along with your impact on the environment - ReVap can help.

ReVap utilizes the energy in the cold CO2 to cool down the main brine system typically in a brewery. As the vaporized CO2 would freeze the brine if the CO2 was heat exchanged directly with the brine, a strong glycol intermediate loop is installed. After evaporation the gaseous CO2 flows through an ambient super heater and exits to the point of use at about 10-20 deg. C, depending on the ambient temperature. The amount of energy saved is approximately 85 kW per 1000 kg CO2 evaporated.

Available in standard sizes from 500 kg/hr.
