Condenser Coil Maintenance:
Refrigerated containers provide extremely reliable and economical solutions for your cold storage needs. What most people don’t realize is that the condenser coil needs maintenance. However, with a little regular maintenance and care, they will provide you with years of service.
Here are a few condenser coil maintenance items and reminders to assure reliable service from your Refrigerated Container.
- Keep the condenser coil clean. With any refrigeration system, keeping the coil washed out and clean is extremely important to your unit’s operations. Dirty coils can cause many problems with the operation of the unit including premature failure of the compressor. Thus, premature failure can cost thousands of dollars to replace. Please refer to the service manual or feel free to contact us with questions on how to clean the coil.
- Repair the unit with OEM parts. Keep the unit in OEM condition and only repair with factory-replacement parts. This is strongly recommended. If the units are altered and not repaired back to OEM standards, troubleshooting the unit is very difficult. In most cases, we stock replacement parts can have parts sent to you by the next day of your order.
- Evaporator Coil Icing. Much like most walk-in freezers, from time to time the Evaporator coil will build up with ice which will eventually block the airflow and can cause premature failure of the compressor if left unchecked. This usually occurs with heavy door openings and leaving the doors open for extended periods of time. When this occurs it will be necessary to remove the product and allow the unit to thoroughly thaw and dry out by running the unit in heat mode and leaving the rear doors open. Also, we recommended the top rear cover be removed in the evaporator section and assure the drain tube is free and clear.
