The Chill-Out senses freezing temperatures within any 6-in. section along its length. The solid state sensor can replace fragile and difficult-to-install gas capillary tubes and their mechanical switches. Unlike capillary tubes, it can be installed horizontally or vertically or formed to fit any shaped system.

Sensor elements are available in a variety of styles including bendable aluminum tubing, ultra-flexible brass armor, and hinged epoxy glass strips. The electronic shut-off control can be mounted at the measuring point or within a central control box for convenient monitoring. An LED on the control box indicates a tripped condition and a manual reset button allows the operator to quickly re-instate the system.

Standard models have a 41°F setpoint with a DPDT relay. Custom models are available with any required trip point.
