The GCW is the answer when neither an outdoor nor a ducted solution works. Installed in a technical room separate from the cellar, it rejects heat to water rather than air — a chilled water loop, a cooling tower, or once-through on the mains supply.

Pricing on request. Every cellar is sized from a thermal load calculation, so BartechCo quotes each unit against your project. Request a quote or contact us for specifications, lead times and installation.
