Chromalox Heat Trace Controls

Product Description

The Chromalox Heat Trace Controls are designed in control panel or touch-screen format, these units perform single or multiple zone temperature operation. They are PLC based and pre-wired to support 8, 12, 24, 48, and 96+ circuits. These panels provide an accurate and dependable control system for environmental management. Offering enhanced productivity while lowering operational cost, all panels are assembled and wired in a NEMA rated enclosure and ready for installation. They are also easy to program and suitable for Class I, Division 2 environments. All panels are UL and CSA approved as well as tested to work in hazardous locations. Chromalox offers best in class digital thermostats, industrial controls, and accessories designed for the most demanding heat trace applications.
