Ruffneck RGE regular-duty electric unit heaters

Where RGE fits

RGE is a fan-forced electric unit heater for regular-duty space heating. The catalog lists facilities such as warehouses, factories and mechanical rooms. Electric elements provide the heat; a steam or hot-water piping system is not required.

Start with the room’s heating requirement and available electrical service. A replacement request should include the existing nameplate and the reason for replacement, especially if the space use, ventilation or electrical supply has changed.

Construction and airflow

The catalog describes tubular elements, adjustable discharge louvers, an epoxy-painted steel cabinet and a motor outside the element bundle. RGE is intended for horizontal airflow. A ceiling bracket is standard; wall brackets depend on the selected heater size.

Air distribution deserves attention alongside output. Include the proposed mounting height, nearby obstructions and the area requiring heat so the placement can be reviewed with the heater selection.

Controls and electrical details

Contactor and thermostat packages are ordering choices. Give Tillman the voltage, phase, frequency and desired control arrangement rather than relying on the model number alone.

The current catalog identifies 120 V standard controls for 15 kW and larger units at 480/600 V. The linked March 2022 manual predates that catalog change. Confirm the supplied wiring diagram and actual unit before selecting replacement controls.

Location limits and the RGE/RGX choice

The owner’s manual limits RGE to indoor use and prohibits hazardous atmospheres, wet or humid environments, and corrosive atmospheres. Its maximum operating ambient is 104°F (40°C). An industrial building alone does not establish suitability.

RGE is the regular-duty family; RGX is the heavy-duty family and supports horizontal or vertical airflow. Neither family should be treated as explosion-proof. Send the site classification and exposure details when the location is uncertain.
