Commercial refrigerators such as reach-in coolers are designed to safely store food products within easy reach, and in most cases, house critical refrigeration components inside the base of the unit. Air intake grills are typically located at foot traffic level and are prone to suck in floor dirt, carpet lint, and food ingredients along with necessary air, especially in commercial establishments. In refrigeration cases, a dirty clogged condenser coil restricts airflow and makes the system work harder and longer, leading to early failure. Dirty units consume 5-20% more electricity to maintain optimal food safety temperatures.
Refrigeration condensers require regular cleaning, monthly at a minimum.
