Commercial Refrigeration – Motak MPR-67-X

The customer reported that the unit was not maintaining proper temperature, with the internal temperature around 50°F. This posed a risk to stored products and daily business operations.

Diagnostic Findings

• ✅ Significant ice buildup on the evaporator due to warm, humid air entering the unit
• ✅ Upper lids were frequently left open
• ✅ A large opening allowed direct airflow into the refrigerated compartment

The issue was not a mechanical failure, but an operational/exploitation problem.

Actions Performed by Our Team

• ✅ Performed a partial defrost cycle to remove main ice buildup and restore airflow
• ✅ Cleared visible ice and moisture from the evaporator to reduce the risk of overheating
• ✅ Trained staff on proper defrost procedures to safely defrost the unit without damage
• ✅ Demonstrated correct operation practices: keeping lids closed, minimizing open time, monitoring temperature and cooling levels
• ✅ Developed simple daily procedures for the staff: checking temperature, visually inspecting the evaporator, reducing warm air infiltration

These measures stabilized the unit, protected the products, and allowed the business to continue operating without downtime.

Recommendations for Staff

• ✅ Always keep lids closed
• ✅ Ensure all openings into the refrigerated compartment are sealed
• ✅ Perform regular manual defrost according to instructions
• ✅ Monitor temperatures over the next 24–48 hours
• ✅ If issues recur, request additional inspection

Final Note: Thanks to quick action and a creative approach by our team, we taught the staff how to properly manage the equipment, prevented potential losses, and prepared the unit for safe operation in the future.
