1. Application: Replacement glycol chiller for existing wine tank cooling system in the College Cellars production winery. Existing glycol distribution piping and tank controls remain in place. 2. Type: Packaged, air-cooled industrial glycol chiller for winery service. 3. Nominal Capacity: Minimum 120,000 BTU/hr (10 tons) at standard rating conditions. Minimum 96,000 BTU/hr (8 tons) at 28°F leaving glycol, 30–35% propylene glycol, and 90–95°F ambient (vendor must provide performance data at these conditions). 4. Location: Outdoor pad adjacent to cellar; unit must be weatherproof and outdoor-rated. 5. Refrigerant: R-410A or equivalent code-compliant refrigerant suitable for low-temperature glycol service. B. Operating Conditions 1. Leaving Fluid Temperature Range: Adjustable temperature range appropriate for normal winery operations, including cold-soak, fermentation temperature control, and cold stabilization (typically 20–70°F adjustable range, vendor to specify). 2. Ambient Temperature Range: Operating capability of 0°F to 100°F ambient (or wider), with no loss of rated capacity at 90–95°F.
