Gas and Process Sample Transport Systems for Analyzer Applications















Designed specifically for analyzer enclosures

O'Brien AE and ALE Series industrial heaters are designed to withstand the most damaging abuse and rugged service required in the petrochemical and other industry applications. Each unit includes a cast heater, junction box, insulating spacers and optional thermostat.

Insulating spacers and mounting feet position the heater to make the most of natural convection currents and minimize heat sinks.

Proven Quality
Based on O’Brien’s standard heater design the A series heaters have a twenty-five year history of industrial use and over 10,000 hours of testing. A series heaters have been designed to run cooler and now incorporate an automatically resetting temperature fuse to prevent premature failure when operated at elevated temperatures. Five standard wattages and thermostat set points allow a choice of twenty-five heater combinations.

Because of its small footprint and fin design the ALE series is ideal for use in small enclosures and can be mounted vertically as well as horizontally.

The AE series heaters are available up to 400 watts and 115, 208, 244 and 277 volts. Factory set thermostats are available for 50, 75, 100, 125 and 150F limits. They can also be ordered without a factory thermostat for use with your temperature control system.
