Avoid Emergency Service Calls: Stop Frozen Coils

In this video

When capacity outruns the load, suction pressure and coil temperature can drop far enough to freeze the evaporator — a common cause of emergency, no-cooling service calls. By modulating capacity to the load, the APR Control keeps coil conditions in their normal range and helps prevent freeze-ups.

Key takeaways

• Excess capacity at low load can drive the coil below freezing
• Frozen coils cause no-cooling calls and raise the risk of liquid slugging
• Modulating capacity keeps coil conditions in range
• Helps prevent freeze-related emergency service
