A convection alternative for industrial spaces
CX1 ProVector is an electric convection heater for hazardous-location space-heating applications. It provides a different arrangement from a fan-forced unit heater. Review the available wall space, heat-loss requirement and classification before selecting either approach.
For equipment-area heating or a retrofit, a dimensioned photograph often helps identify practical limitations. Include the service area around the heater and nearby equipment rather than just the existing cabinet width.
Features to consider during selection
The catalog lists single- and three-phase models, a sloped-top cabinet, finned elements and optional built-in temperature control. Stainless-steel cabinet construction is available. These choices help define the installation; they are not a substitute for checking the model’s rating.
Keep the air inlet and upper discharge path unobstructed. Storage placed near a heater can interfere with heat circulation and access even when the heater itself fits the available wall space.
Thermostat choice and approval markings
The CX1 manual distinguishes approval information for units with and without a built-in thermostat. Gas-group and temperature-code suitability must therefore be checked for the selected configuration, not assumed from a general family description.
CF1 and CX1 literature should not be mixed to establish an approval. Send the project classification and the complete proposed model number, including options, to Tillman for review.
Exposure and ongoing maintenance
The owner’s manual specifies dry indoor installation and a maximum ambient of 104°F (40°C). It also excludes atmospheres corrosive to steel or aluminum. Describe the actual contaminants and exposure conditions before treating an optional material as a solution.
Plan access for cleaning and inspection as well as installation. Follow the exact manual and supplied instructions for clearances, permanent mounting and electrical work. Hazardous-location equipment should be serviced by appropriately qualified personnel.
What to send Tillman
- Calculated heating duty, design temperatures and area layout
- Class/division or zone, gas group and required temperature code
- Voltage, phase, frequency and proposed thermostat option
- Mounting dimensions, clearances and airflow obstructions
- Ambient and chemical exposure; existing model/serial labels for replacement
Common questions
Does a built-in thermostat leave every approval unchanged?
Not necessarily. The manual separates approval information by thermostat arrangement; check the exact model.
Can CX1 be installed outdoors?
The reviewed owner’s manual specifies dry indoor use. Review any different exposure with Tillman and the manufacturer.
Can I reuse the old heater’s electrical information?
Send it as reference, but verify the new model, supply and project requirements before ordering.
