A glycol power pack is the heart of a long-draw draft beer system — it chills a propylene-glycol and water bath and circulates it through lines bundled alongside the beer lines, holding every pour at serving temperature from the keg cooler to the faucet, no matter how far the run. Propylene glycol is a non-toxic, food-grade antifreeze, and it never touches the beer.

The Micro Matic Pro-Line MMPP4307 is the top of the Pro-Line range — 11,500 BTU of cooling and a 1-1/2 HP compressor built for ultra long-draw systems, multi-tower bars, breweries, and stadium concourses. A large, well-insulated glycol bath lets the compressor cycle less often, extending compressor life and cutting service calls.

Specifications

• Cooling capacity: 11,500 BTU
• Compressor: 1-1/2 HP
• Cooling agent: food-grade propylene glycol
• Configurations: 2-, 3-, or 4-pump; air-cooled, water-cooled, or remote condensing (choose your configuration above)
• Reach: ultra long-draw runs up to ~825 ft depending on configuration

Features

• Sight glass — check glycol bath level without removing the lid.
• Digital thermostat — accurate, easy-to-read glycol temperature display.
• Rotary vane pumps — industry-standard, ultra-reliable, and easily serviced; multiple independent glycol loops.
• Thermally efficient bath — large capacity with expanded-foam insulation, so the unit runs less and saves energy.
• Lift-off deck lid — fully assembled upper deck for easy serviceability.
• Smart Draft™ — temperature monitoring that flags issues with the power pack or walk-in cooler in real time.

Sizing & setup

As a rule of thumb, plan for roughly 3/4 HP per 100 ft of insulated trunk-line run, adding headroom for high tap counts or hot mechanical rooms. With 11,500 BTU and up to four independent pumps, the MMPP4307 drives the longest, highest-tap-count systems. Fill the bath at a 40% glycol / 60% distilled-water ratio — distilled water keeps impurities out of the thin-plate heat exchanger. Need help sizing a multi-pump system?

Warranty: 18-month parts and 1-year labor from date of sale, plus an additional 3-1/2 years on the compressor.
