Fenwal 01-018002-000 Thermoswitch

The Fenwal 01-018002-000 Thermoswitch is a high-precision, industrial temperature controller designed for mission-critical thermal regulation. This direct replacement for 01-018000-000 utilizes a differential expansion design where the high-expansion 300-series stainless steel outer shell reacts immediately to temperature shifts, moving the internal contact assembly. Engineered for high-temperature applications ranging from -100°F to 600°F, this 0.625-inch diameter thermoswitch features open-on-rise logic, breaking the circuit when the set point is reached. The coupling head construction and brass head ensure secure mechanical integration in hydraulic laminating presses, hot stamp printers, and deep-fat fryers. Unlike electronic sensors, this Fenwal thermostat operates without external power, providing vibration-resistant performance and sub-degree sensitivity. With 8-inch wire leads and a rugged 120V rating, it is a field-proven HVACR component for contractors requiring repeatable accuracy in harsh environments including textile platens and paint drying equipment.

Key Benefits for Technicians:

• Wide Operating Envelope: Capable of managing thermal cycles between -100°F and 600°F with minimal drift.
• Fast Thermal Response: The 300 stainless steel shell acts as the sensing element for fast-acting temperature control.
• Mechanical Reliability: Inherently vibration-resistant design ensures the set point remains stable in industrial machinery.
• Versatile Mounting: Features a coupling head type for easy installation into pressurized or threaded ports.
• Simplified Wiring: Integral 8-inch leads facilitate quick field connections to 120V control circuits.

Common Questions:

Is the Fenwal 01-018002-000 adjustable in the field?
Yes, this unit features an internal adjustment screw that allows technicians to calibrate the specific set point within the rated temperature range for precise system integration.

What is the difference between this and the 01-018000-000?
The 01-018002-000 is the current manufacturer-designated direct replacement for the discontinued 01-018000-000, maintaining the same electrical ratings and physical dimensions.

Does this switch require a separate controller?
No, the Fenwal Thermoswitch is a standalone electromechanical device that opens the circuit on temperature rise without the need for additional power or logic controllers.
