Winterization boxes protect sensitive field instruments from extreme cold, moisture, and harsh outdoor conditions. These enclosures maintain a controlled environment around transmitters, sensors, gauges, valves, and displays so they continue to operate reliably throughout winter. Control Innovations supplies winterization boxes built for industrial sites, including locations that require hazardous‑area ratings.
A winterization box provides a heated, insulated enclosure that shields delicate instruments from freezing temperatures and weather exposure. By maintaining a stable internal temperature, the box helps prevent failures, erratic readings, and downtime in cold‑weather environments.
Key Features
Control Innovations winterization boxes typically include:
- Fiberglass, steel, or stainless‑steel enclosures
- Integral or custom‑installed insulation
- Clear inspection window for viewing instruments
- Thermostatically controlled heater
- Heater disconnect mounted below the enclosure
- 120 V or 24 VAC heater options
- Hazardous‑area‑rated heater and disconnect when required
This creates a dependable, field‑ready protection system for outdoor instruments.
Enclosure Construction
A typical winterization box may include:
- Insulation applied inside or outside the enclosure
- Optional heated blankets wrapped around the enclosure when internal heaters are not needed
- Enclosures with built‑in insulation and molded viewing windows
- Rugged construction suitable for industrial and remote locations
- Space for powering EHT (electric heat tracing) for instrument tube bundles
This ensures long‑term durability and consistent temperature control.
Installation & Integration
Winterization boxes are designed for straightforward field installation:
- Heater disconnect installed below the enclosure for safe servicing
- Internal space for power supplies, terminals, or small auxiliary components
- Mounting options for wall, pole, floor, or overhead installations
- Suitable for single instruments or multi‑device assemblies
This supports reliable operation in cold climates and demanding outdoor environments.
