The Problem – Dirty & Clogged Condenser Coils
Refrigeration systems are designed to safely store food products within easy reach, and in most cases, house critical refrigeration components inside the base of the unit. These components, including the air intake grill, located at foot traffic level are prone to suck in ground dirt, carpet lint and food ingredients along with necessary fresh air. In refrigeration cases, a dirty clogged condenser coil restricts airflow and makes the system work harder and longer, leading to early failure. In addition, the dirty unit consumes 5-20% more electricity to maintain optimal food safety temperatures.
Food service equipment can be energy intensive and neglect can be costly. Refrigeration condensers require regular cleaning, monthly at a minimum. Depending on the food service environment, cleaning routines can range from blowing contaminants off the coils with compressed air, brushing surface areas clean to messy chemical cleanings — procedures that can result in undesired airborne debris polluting the surrounding area.
The Solution – PreVent Air Intake Filters
The most logical and cost effective solution would be to keep the dirt and grime out of the unit after it’s been thoroughly cleaned and serviced.
Save time and money by installing an external washable electrostatic air intake filter to new or existing reach-in-coolers, ice makers, freezers, and refrigerated display cases. Permatron’s PreVent Model R air intake filter features a steel frame with a patented magnetic design. These air intake filters can be custom sized to stick to the outside of metal air intake louvers, making them accessible from the outside with no need to dismantle the case for frequent coil cleaning. Staff can easily see dust build up on the surface of the air filter, which can be rinsed or vacuumed off and reinstalled in minutes.
