Chromalox WTP WeatherTrace Freeze Protection Panel

The Chromalox WTP series freeze protection heat trace panels offer power distribution, ground-fault protection, individual circuit alarming, and ambient sensing control. The panels are housed in NEMA 4 enclosures for indoor/outdoor applications. NEMA 4X 304 stainless steel enclosures may be selected as an option for more harsh environments. The WTP units can be configured with 50 to 250 Amp main breaker ratings in Single and Three-Phase configurations. Branch circuit breakers are available in 15, 20, 30, 40, and 50 amp single-pole and two-pole configurations with 30mA ground-fault equipment protection.

The WTP panels provide group control of multiple heat trace circuits for pipe freeze protection via an ambient sensing external thermostat or electronic controller. The WTP can also be configured for group control of snow melting or deicing applications using our internal temperature/moisture controller. Chromalox recommended controllers include: ChromaMelt-2R, RTAS, RTBC or the TPR. The WTP may be operated in two modes; automatically with the external controller, or in manual override via the Hand/Off/Auto selector switch.
