Caloritech SS1391 120V 750W 23.5-Inch Strip Heater
The SS1391 is a 23.5-inch Caloritech strip heater rated at 750W and 120V. It has the same listed length as SS1361 but a higher power rating, so it should not be chosen as an automatic upgrade solely because the strip fits the available space. The heating assembly, electrical supply and temperature-control design must support the intended selection.
Specifications and included details
- 120V and 750W electrical rating; heat output listed at 2559 BTU/hour.
- 23.5-inch strip with an aluminized-steel sheath.
- Two offset bolt terminals at one end and 5/8 x 9/32-inch mounting slots.
- The listed maximum product temperature is 1000°F (538°C), not a guaranteed process setpoint.
Before ordering
Verify the required wattage, electrical circuit and manufacturer mounting drawing before substituting SS1391 for another 23.5-inch strip. A qualified installer should evaluate the application and external controls. Do not infer drying time, condensation prevention or a particular workpiece temperature from the power rating.
Product questions and answers
How does SS1391 compare with SS1361?
Both are listed at 23.5 inches and 120V. SS1391 is 750W, while SS1361 is 500W. Confirm that the equipment and control design require and support the selected power rating.
Does the 1000°F listing give me a regulated heating temperature?
No. It is a listed maximum temperature specification, not a control setting or a promised workpiece temperature. The application requires suitable sensing and control.
Are the slot dimensions enough to confirm that SS1391 fits?
No. The listing gives 5/8 x 9/32-inch slots, but slot positions, body clearance and terminal space must also be checked against the manufacturer drawing.
