WHAT IS IT?
Focused Heat System
A focused defrosting system for walk-in freezers.

The Problem
Ice builds up on the refrigerant distribution (spider) valves in walk-in freezers. It’s a common cause of refrigerant line failure and door damage, and it costs businesses money in repairs and lost product.
The Solution
An add-on heating system that defrosts the distribution valve, eliminating ice build-up and preventing fractures.
The Pay-Off
Used in many warehouse clubs and grocery stores across the nation, helping them operate with confidence and avoid costly repairs and lost product.
