Chromalox CWM constant wattage heating cable is a proven, reliable solution for industrial process temperature maintenance and freeze protection. CWM features a parallel heating core that produces uniform thermal output over its entire length. Using a single power point, you can easily configure and install a heat tracing system as short as several feet or as long as 780 feet right in the field. System design only requires that you match the CWM cable thermal output to the heat loss of your piping system. CWM is flexible at most ambient temperatures and can be wrapped around piping and complex fittings. It is rugged, easy to monitor and maintain temperature, and has zero inrush at start-up. With 392°F (200°C) fluoropolymer electrical insulation overjacketing, CWM has outstanding electrical and thermal properties, and is well suited for most chemically hostile environments. An extensive range of wattages and voltages are available immediately from Chromalox stock.
• Durable, non-aging fluoropolymer jacket ensures long service life and can be used in most hostile environments.
• Flexible, easy to install on most equipment and delivers long-term reliable performance.
• No Inrush current.
• Accurate temperature, reliable electric heat that can be consistently controlled and easily monitored.
• Safe and rugged.
• Parallel circuitry allows cut-to-length.
• High performance, rated to withstand up to 392°F saturated steam (190 psig) temperature (power off).
• Low profile, uses standard size thermal insulation on piping and process equipment.
UL Listed for ordinary areas.
CSA Certified for ordinary and:
• Class I, Div. 2, Groups A, B, C, D
• Class II, Div. 2, Groups F, G. Rated T3 Temperature Class2.
1. Depends on specific model.
2. Exception: Cable surface temperature shall not exceed 190°C in Class II, Div. 2, Group F; 165°C in Class II, Div. 2, Group G.
Note: The CWM cable is sold by the foot and therefore a custom order. Once the order is placed it cannot be cancelled or returned once you receive the cable. This is because the cable is cut to length here, or at Chromalox, for your order, from your requested length.
