Protecting Electrical and Control Cabinets from Winter Damage
Outdoor electrical and control cabinets are often the heart of industrial operations. They house sensitive components that keep pumps running, lights on, and critical systems online. When winter temperatures drop, the metal walls of these enclosures provide no insulation. Inside, cold air can condense moisture, freeze wiring, crack fittings, and even shut down equipment when it is needed most.
The Problem: Cold and Moisture Inside Metal Enclosures
Unlike climate-controlled spaces, metal control cabinets, breaker boxes, and other outdoor electrical enclosures are directly exposed to freezing temperatures. Once the metal walls drop below freezing, internal temperatures can follow quickly. The risks include:
-
Frozen wiring and terminals that can crack or fail
-
Condensation leading to corrosion or shorts
-
Damage to programmable logic controllers (PLCs), relays, and other sensitive electronics
-
Downtime and costly repairs
Insulating the enclosure helps but cannot generate heat. Without an active heating solution, you are leaving critical components exposed to the elements.
The Solution: Smart Freeze Prevention Heaters
Xtreme Heaters’ freeze protection compartment heaters are designed specifically for enclosed spaces like metal electrical cabinets, control boxes, pump enclosures, and similar applications. These are not repurposed space heaters. Each unit is purpose-built with:
-
Automatic thermostat control: Heaters turn on only when temperatures drop near freezing, maintaining safe internal temps without wasting energy.
-
Rugged construction: Designed to handle damp, dirty environments common in outdoor enclosures.
-
Compact design: Fits into tight spaces inside cabinets and electrical panels without interfering with wiring or access.
-
Ignition and moisture protection: Tested for safe use around electrical components in demanding conditions.
Where These Heaters Make the Biggest Difference
Industrial operations use our heaters anywhere vital components live inside metal enclosures exposed to freezing weather, including:
-
Outdoor electrical panels and switchgear cabinets
-
Control boxes for pumps and compressors
-
Traffic signal and communications enclosures
-
Backflow preventer enclosures and utility cabinets
Whether you manage one cabinet or a network of critical infrastructure, keeping the internal temperature stable protects equipment and prevents unplanned outages.
