Fenwal 01-018002-021 Thermoswitch
The Fenwal 01-018002-021 Thermoswitch is a precision-engineered immersion temperature controller designed for rapid response and high durability in demanding industrial environments. Utilizing the differential expansion principle, the 316 stainless steel shell acts as the active sensing element, ensuring minimal thermal lag compared to standard bulb-and-capillary units. This Open on Rise switch is rated for a broad operating temperature range of -100°F to 600°F, making it suitable for high-heat applications where maintaining setpoint stability is critical. The coupling head design and 0.625" diameter housing allow for straightforward integration into existing piping systems or tanks. With its brass head construction and 8-inch wire leads, this Fenwal temperature control provides reliable electrical continuity and vibration resistance, ensuring the electrical contact assembly remains protected even under mechanical stress. For contractors requiring a snap-action thermal switch with high sensitivity and repeatable accuracy, the 01-018002-021 remains an industry standard for fluid or gas temperature regulation.
- Rapid Thermal Response: The outer sensing shell expands and contracts instantly with temperature changes, providing faster cycle times than competitors.
- Severe Service Durability: Constructed with a 316 stainless steel outer tube to resist corrosion and withstand high-pressure environments.
- Precision Calibration: Features a coupling head type adjustment for fine-tuning setpoints across a wide 700-degree Fahrenheit span.
- Compact Form Factor: The 5/8-inch diameter and integrated leads simplify installation in tight mechanical headers and HVACR manifolds.
How do I adjust the setpoint on a Fenwal coupling head Thermoswitch?
Adjustments are made by rotating the internal screw located within the coupling head. Rotating the adjustment screw changes the tension on the internal strut assembly, allowing you to calibrate the opening temperature to your specific application requirements.
Is the Fenwal 01-018002-021 suitable for direct immersion in corrosive liquids?
Yes, the 316 stainless steel shell provides excellent resistance to many industrial chemicals and fluids. However, always verify that the brass head and any sealing materials are compatible with your specific medium and local plumbing codes.
What is the maximum current rating for this thermal control?
While ratings vary by voltage, these units are typically used in pilot duty applications or to drive contactors. Always verify your specific load requirements against the primary electrical ratings to prevent contact welding or premature switch failure.
