Dimpled Cooling Jackets Low-pressure dimpled jackets for glycol and water are available also high-pressure flow of freon or ammonia. These systems ensure continuous, precise control of temperature. Refer to glycol flow chart for differences in channel and dimpled jackets.

Dimpled Cooling Panels/Press Dimpled Jackets Dimpled cooling panels (left) may be installed in tanks during fabrication or in storage tanks on-site at the winery. Press dimpled cooling jackets (right) are easily added to existing tanks. Both may also be added to existing inefficient temperature control systems. Comes in polished finish or standard 2B. Heat jackets may be added to the floor for immediate heat tranfer to wine as you fill. They can be placed on tanks set on stands or concrete pads. May sometimes be added to exisiting tanks in field.

Channel Jackets Tanks with channel jackets can keep wine chilled with a mixture of glycol and water circulating through channels at low pressure.
