Guardian heat-traced safety stations prevent freezing in extreme cold weather conditions down to -40°F. These thermostat regulated units feature a self-limiting heat-tracing cable wrapped around internal piping that activates when the pipe temperature falls below 75°F to prevent freezing within the unit. Guardian's offering of freeze protected safety stations includes a complete selection of accessories and alarm options to meet the needs of any hazardous environment. Know your NEMA enclosure types and hazardous locations when selecting equipment.
