Because it’s typically high-volume operations utilizing these units, any downtime can cause big service disruptions and should be avoided whenever possible.

Jeffrey M. Brightly, owner of JMB Repairs Inc., Lake Worth, Fla., gives his advice on keeping rethermalizers operating seamlessly.

• Many have self-cleaning capabilities using chemicals, tablets and/or liquids. If not, the task is manual and requires a great deal of labor.
• Cleaning schedules for rethermalizers depend on the amount of use. Typically, this involves a quick cleanout daily and good thorough cleaning weekly. The process entails wiping down all sides, pulling the equipment out if possible and making sure lint, dust and grease are removed from the vent so it can breathe properly.
