What our Experts Think

Q&A

Q: What is the Micro Matic MMPP4301-EP used for?
A: It is a commercial air-cooled glycol draft beer power pack designed to chill and circulate glycol for long-draw beer systems in bars, restaurants, and taprooms.

Q: What is its main function?
A: It maintains consistent beer temperature over long distances by circulating glycol through trunk lines, ensuring beer stays cold from keg to tap.

Q: What cooling capacity does it have?
A: It provides approximately 2,300 BTU cooling capacity using a 1/3 HP air-cooled compressor for reliable performance in commercial setups.

Q: Does it include a glycol tank?
A: Yes, it features a glycol bath (about 4.5 gallons) that stores and cools the glycol solution for circulation through the system.

Q: How many pumps does it use?
A: This model includes one vertical circulating pump to move glycol through the draft system efficiently.

Q: What type of businesses is it best for?
A: It is ideal for high-volume bars, breweries, stadiums, and restaurants that need reliable long-distance draft beer delivery.

Q: What voltage does it require?
A: It operates on 115V single-phase power with standard commercial electrical connection.

Q: Why is a glycol system important?
A: It prevents temperature loss in long beer lines, reduces foam, and ensures consistent taste and quality at every tap.

Q: Is it suitable for small bars?
A: Not typically—this unit is designed for long-draw or large multi-tap systems, not simple short-distance bar setups.

Maintenance Tips

• Glycol level check (monthly): Keep bath filled to indicator line; top up with approved glycol mix (typically 2.5:1 water to glycol).
• Glycol change (every 12–18 months): Replace solution to prevent contamination and maintain cooling efficiency.
• Inspect for ice buildup: If freezing occurs, fully thaw and replace solution immediately.
• Clean condenser coils (every ~60 days): Removes dust buildup and prevents overheating or compressor failure.
• Ensure proper airflow: Maintain clearance around unit; blocked vents reduce cooling performance and can cause shutdowns.
• Check glycol pump operation: Listen for smooth circulation; replace pump if flow weak or inconsistent.
• Inspect insulation on trunk lines: Damaged insulation leads to temperature loss and foam issues.
• Electrical safety check: Periodically inspect wiring, thermostat function, and connections for wear.
• Monitor system temperature: Maintain stable glycol temperature (~29°F / -2°C typical setpoint range).
