Delfield Refrigeration Evaporator Coils

Commercial refrigeration systems, such as display cases, cold rooms, and ice machines, require Delfield evaporator coils. Evaporator coils are a series of tubes through which refrigerant flows and helps transfer heat, keeping products at optimal temperatures. When the refrigerant evaporates, it draws heat from its surrounding environment, cooling air or products being cooled inside of the equipment. The cycle then is repeated with the cooled refrigerant circulating back to the compressor. Evaporator coils can become dirty clogged, or simply damaged over time – reducing efficiency. Signs that you may have coil issues include uneven cooling, higher energy consumption, and frost build-up. Optimal performance and staying away from equipment breakdowns demand regular and timely maintenance and replacement.

FAQs

Can I clean a Delfield evaporator coil myself?

While cleaning is possible, it's often recommended to consult a professional for deeper cleaning or coil replacement.

How often should evaporator coils be replaced?

The replacement frequency depends on usage, maintenance, and environmental factors. Regular inspections can help determine when replacement is necessary.   

What causes evaporator coils to freeze up?

Insufficient refrigerant, blocked airflow, or a faulty thermostat can lead to evaporator coil freezing.

How do I know if my evaporator coil is damaged?

Signs of damage include leaks, bent fins, or corrosion. A professional technician can assess the coil's condition.
