Key Features
- Correct 230V Rating — Matched to the electrical specification of the CB-12 control box, ensuring safe and proper operation at the designed voltage.
- Genuine OEM Component — Sourced directly from Multiquip, this is the same heater installed at the factory — no substitutions or compromises.
- Direct-Fit for CB-12 Control Boxes — Engineered to install into CB-12 enclosures without modification, maintaining the integrity of the control box assembly.
- Protects Internal Components — Keeps the control box interior above condensation-forming temperatures, helping prevent moisture-related damage to sensitive electrical components.
- Electrical Safety Compliance — A correctly rated, OEM-specified heater element ensures the control box operates within its designed thermal and electrical parameters, reducing the risk of faults or component damage.
A control box heater is a low-wattage heating element installed inside an electrical enclosure to prevent condensation from forming on sensitive components such as contactors, relays, and circuit boards. In pump control applications, moisture infiltration is a leading cause of electrical failure — the heater maintains the internal temperature of the CB-12 box just above the dew point, keeping surfaces dry even in humid or cold jobsite conditions. When this heater fails or is missing, condensation can accumulate inside the enclosure, leading to corrosion, short circuits, and premature failure of the control box.
