WTP & WTPM Freeze Protection Panels
Energy Efficient
Optimized for efficiency gains across your processes.
About the Product
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.
100 and 225 amp bus ratings in Single and Three-Phase configurations. Branch circuit breakers are available in 20, 25, 30 and 40 amp single-pole and two-pole configurations with 30mA ground-fault equipment protection.
WTP – Freeze Protection Ambient Sensing Series
The WTP series controls multiple heat trace circuits via an ambient sensing external thermostat, external electronic controller or via an external snow sensors. Chromalox recommended controllers include: ChromaMelt-2R, RTAS, RTASEP, B100, E100 or the EUR-5A. The WTP may be operated in two modes; automatically with the external controller, or in manual override via the Hand/Off/Auto selector switch.
WTPM – Freeze Protection Ambient Sensing Monitor Series
The WTPM WeatherTrace with the HMI Monitoring, continually monitors the supply voltage to each individual heat trace circuit. Loss of voltage or a ground fault condition will trigger an automatic alarm condition, alerting plant personnel of critical process problems and reducing downtime. An annunciator panel then identifies the faulted zone and a Common Alarm is activated with the re-ring feature.
The WTPM panels provide group control of multiple heat trace circuits for pipe freeze protection via an ambient sensing thermostat, electronic controller or door mounted HMI. The WTPM 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 TPR with HMI.
The WTPM may be operated in two modes; automatically with the external controller or in manual override via the Hand/Off/Auto selector switch.
