We remember the contagious excitement created at our first meeting with Aron Hess and Ken Johnston at 12th and Maple Winery in Dundee, Oregon. They excitedly shared with us their vision to create the finest, most advanced, wine making facility in the state of Oregon. We are so grateful to be given the opportunity to manufacture for them a glycol chiller and heating system to match this vision.

     

The Chiller System consisted of two 50 HP Cooling Modules. Each Module was supplied with two independent 25 HP Refrigeration circuits.

     

One challenge was designing a pumping system to handle the fluctuating load. We manufactured two independent pump skids, each supplied with three stainless steel centrifugal pumps. Each pump is driven by an independent variable frequency drive that maintains a constant preset Glycol Supply pressure, only running as much pump as the current load requires.

     

One unique feature was incorporating heat reclaim exchangers. These heat exchangers enable 12th and Maple to recover 50% of the discharge refrigerant heat (heat that is normally rejected to the outside air). This supplements the glycol heating system, that is used to warm the juice for optimum fermentation control.

We appreciated the many challenges of this project, working with them to design both a cooling and heating system for their wine tanks. It is an incredible facility, we look forward to enjoying the fruits of our labor soon!!!
