Green Cryo TM, cooling processes from Pera Pellenc, winemaking equipment

Green Cryo TM

Multifunctional chiller equipment for grapes and wines.

Green CryoTM is an innovative multifunctional chiller that can treat fluids with solid parts (grapes, must, wine and lees) as well as liquids (water or glycol). With its original design, Green CryoTM can produce both cold and heat.

“The tests were carried out with fresh grapes, musts in fermentation and flash musts. We combined the cooling of the grapes arriving in the cellar with maintaining constant temperature of the tanks in alcoholic fermentation. We connected the group to the switch indicators of our alcoholic fermentation tanks. This type of equipment provides flexibility in cooling operations as in general the chiller in the cellar cannot cool grapes and liquids. For cellars needing slow to average flow, it is definitely more economical as it replaces 2 systems, which saves on operating expenses. It is small, more ecological and clever: the heat can be reused to heat the water which is always useful during vinification to reactivate the yeasts, help start malolactic fermentation or clean the cellar.”

Green Cryo TM: cleaning the winery
Cleaning the winery


Green CryoTM is a mobile multifunctional chiller comprising :
• a pressure reducing valve
• a compressor (Scroll)
• a condenser (dual air and water condenser).

The refrigerant used is pure (R134a) which absorbs heat in the evaporator (on the grapes, musts, cold water, etc.) and releases some into the condenser (in the ambient air or to produce hot water to use in the winery). The refrigerant makes the transfer.

Diagram of Green Cryo TM’s 3 concentric tubes

This evaporator is designed with 3 concentric circular tubes :
• The inner tube allows the grapes, must or wine to circulate
• The first annular space allows the circulation of the refrigerating gas
• The 2nd annular space allows the circulation of the liquids: water and glycol.

Energy is recovered by a plate heat exchanger which can heat water to obtain excellent energy performance (COP>6). Hot water is produced for the same operating costs and can be used to reactivate yeasts, heat for malolactic fermentation, wash the winery or other purposes.

Green CryoTM is an essential part of your vinification processes and treats all products in the cellar.
