IntelliTrace Control Panels

Chromalox® IntelliTrace™ microprocessor-based panels offer comprehensive control, monitoring,
and power management for demanding industrial heat trace applications. Available in ambient or
line-sensing models for both ordinary and Class I, Division 2 areas, the modular design scales from
6 to 72 loops with a 40A capacity and 100–600 Vac service.

Advanced features include a 10-inch touch-screen, PID or manual SCR control, soft-start, and
sensor mapping. The system provides extensive data logging and alarms for temperature, current,
and ground fault leakage. Housed in NEMA 4 or 4X enclosures with UL/cUL approvals, these panels
simplify configuration while minimizing costs by allowing users to select only required features.

WeatherTrace Control Panels

Chromalox WeatherTrace™ (FPAS/FPLS) panels provide reliable control for industrial freeze
protection and snow melting. Available in ambient or line-sensing models, they feature NEMA 4
enclosures, thermal magnetic breakers with 30 mA ground fault protection, and manual override switches.

For enhanced reliability, the Sentinal Monitoring (FPASM/FPLSM) versions continually track supply
voltage and ground fault conditions, triggering detailed alarms for specific faulted zones. All models are
UL/cUL approved and offer customizable options like stainless steel enclosures, main disconnects, and
pressurization systems for specialized environments.

Digital Heat Trace Controller, 1 and 2 Circuit

The Chromalox® IntelliTrace™ ITC1/ITC2 is a compact, microprocessor-based controller for single or
dual-circuit heat trace management. Designed for both ordinary and Class I, Division 2 hazardous locations,
it supports various cable types for freeze protection and process temperature control. The unit features
a high-resolution color TFT display, capacitive touch switches, and dedicated LED indicators for real-time
status monitoring.
