Raychem Elexant 450c Controller

Raychem part number: 1244-021970

Raychem Elexant 450c controller and sensor cable

The Raychem Elexant 450c is a next generation controller capable of controlling dual independent trace heating systems (for example pipe freeze protection and grease line maintenance). The controller has multiple integrated sensing modes (line and/or PASC ambient sensing) and remote alarm capability.

An optional separate power bank allows the Elexant 450c to be programmed before a site is connected to the main grid, allowing a contractor to program the controller whilst doing the install and not needing a return visit once the site goes live.

  • Intuitive set-up and programming of the unit with a 4.3” colour touch screen
  • Flexible temperature control of pipe freeze protection and grease line maintenance systems
  • Controls 2 independent heating circuits
  • Line sensing and/or ambient sensing
  • Proportional Ambient Sensing Control (PASC) algorithm for enhanced energy savings in ambient sensing mode
  • Alarm relay with change over contact to signal power, temperature or communication problems
  • Pipe temperature monitoring with high and low temperature alarm
  • Offsite configurable means it can be set up prior to final installation

The Elexant 450c is compatible with XL-Trace, FS-C10-2X and Frostop Black cables in non-hazardous locations.
