How Often Should You Schedule Maintenance for Your Ammonia Refrigeration System?
Your ammonia refrigeration system provides many advantages over traditional cooling solutions. However, like all industrial refrigeration equipment, routine care is crucial for ensuring energy-efficient, reliable performance and maintaining a safe and compliant facility. How often should you schedule maintenance for your ammonia refrigeration system? Learn best practices for ammonia refrigeration upkeep with these tips from CW Refrigeration.
Ammonia refrigeration safety and maintenance guidelines
- Daily/Weekly – perform general operational checks
- Monthly/Quarterly – clean, inspect, and test system function
- Annually/Semi-Annually – replace or rebuild components per run hours or manufacturer guidelines
- Regularly log information according to IIAR, OSHA, EPA, and local safety regulations
Cost of Neglecting Ammonia Refrigeration System Maintenance
Overlooking maintenance needs risks more than inflated energy costs. Poorly maintained systems pose risks to food, employee, and environmental safety. Keeping up with routine and preventive industrial refrigeration system maintenance ensures reliable, energy-efficient operation, fewer costly breakdowns, and a longer system lifespan. It also protects your business against downtime, product loss, regulatory fines, and liability.
