Dimpleflo Must Chillers have been used in the Australian & New Zealand wine industry since mid 1980’s. Dimpleflo Must Coolers incorporate the unique dimple profile and are revered for their efficiency, durability, cleanability and versatility – not only during vintage (grape harvest) but also as an “all round winery heat exchanger”.
Dimpleflo Grape Must Coolers are available in varying lengths from 2 metre to 12 metre and wall-mount or floor mount configurations. Mobile Must Chillers are available up to 4” 100mm cross section. A further variation of the Dimpleflo Double Pipe Heat Exchanger is the inline system. This is typically used in larger wineries to cool the crushed grapes in transit from the crushing area to main winery area for further processing.
These premium Australian designed, and manufactured must coolers can cool crushed grape flows from 2 tonnes/hr through to 150 tonnes/hr. The largest Dimpleflo Teralba have ever built was exported to the USA and chills 150 tonnes/hr of crushed grapes from 30°C to 10°C, in a single process.
Dimpleflo Must Chillers are available with the Vinpro Temperature Control System to monitor and adjust must discharge temperatures. The Vinpro system can be operated as a local or remote control depending on the model ordered.
Teralba Industries also manufacture Accu-Therm Plate heat Exchangers for heating or clear juice or finished wine.
Refrigeration is an essential component of the wine making process, as you need to be able to cool down your grape must and control the temperature of fermentation. For this purpose, we at Teralba build a wide range of highly effective heat exchanger chiller systems, from small (2”) 50mm juice heat exchangers through to (8”) 200m must chillers cooling 150 ton/hr of grape must, that are available worldwide. Dimpleflo Must Chillers are modular so they can grow with your production requirements.
Heat exchangers, such as our robust Dimpleflo Grape Must Cooler and Dimpleflo Double Tube, are devices consisting mostly of a dimpled stainless steel shell and inner tube. They’re used to chill winery must, stabilise wine temperature, heat must for colour extraction, thermovinification and more.
Dimpleflo Heat Exchangers function by having the wine, juice or crushed grapes, flow through a dimpled inner heat transfer tube while glycol flows through the shell surrounding the tube. In simple terms, if the wine or juice is warmer than the glycol being circulated through the exchanger, its heat will be transferred to the glycol, which subsequently cools the wine. The glycol will then circulate through a refrigeration chiller, where it’s cooled again so that it can be recirculated to continually absorb heat from the wine. Dimpleflo Heat Exchangers can also be designed to use direct expanded refrigerants such as ammonia.
The refrigeration chiller uses a brazed plate heat exchanger or semi-welded plate heat exchanger, with ammonia or R12A refrigerant, to cool the glycol before it flows through the jacket around the inner heat transfer tube. The cooled glycol can then repeatedly absorb heat from the wine before having its temperature lowered again by the chiller.
The maintenance needs of a winery process chiller vary from replacing gaskets to sourcing spare parts for obsolete models. This is why we offer our Teralba Heat Transfer Service. We’re happy to make both minor and major repairs, source parts, and perform heat exchanger assessments to identify potential issues.
Teralba is a proud, New South Wales-based provider of premium heat exchangers. Our Dimpleflo Must Chillers are trusted by wine producers from around the world for their efficiency, reliability, and versatility.
