Fenwal 01-018052-000 Thermoswitch
The Fenwal 01-018052-000 Thermoswitch is a high-precision, industrial temperature control designed for demanding HVACR and process thermal applications. This probe type temperature controller utilizes a unique strut-and-tube thermal expansion design, providing an exceptional resolution sensitivity of 0.1 degree F. Built with a 300 series stainless steel unit shell and a jumbo coupling head type, it is engineered for direct integration into electrical conduit or high-pressure environments. Operating as an open on rise switch, the internal contacts disconnect the circuit when the temperature reaches the designated set point, making it a reliable choice for high-limit protection and equipment safety shutoff. The wide-range thermal element handles temperatures from -100 degrees F to 400 degrees F, ensuring consistent switching across cryogenic and high-heat cycles. Featuring 6-inch wire leads and dual 120/240V compatibility, this mechanical thermoswitch is a rugged, software-free solution for contractors requiring fast-acting response and vibration resistance in critical thermal systems.
Key Benefits- Precise Thermal Response: The strut-and-contact assembly provides a slow make-and-break action that reacts to the smallest temperature fluctuations.
- Corrosion Resistance: 300 series stainless steel construction protects the outer shell and head from oxidation and chemical exposure.
- Simplified Integration: The jumbo coupling head allows for direct attachment to conduit for secure, professional wiring.
- Broad Operating Envelope: Capable of managing environments ranging from sub-zero refrigeration to high-heat light industrial processing.
- Durable Mechanical Design: No internal software or digital components to fail, ensuring long-term reliability in high-vibration HVACR equipment.
How do I adjust the temperature set point on this thermoswitch?
The set point is adjusted by turning the internal adjustment screw. Note that for "open on rise" units, clockwise rotation typically increases the temperature setting where the contacts will open.
Can this unit be used in liquid immersion applications?
Yes, the stainless steel shell is suitable for immersion. When installing in a tank or pipe, ensure the coupling head is properly sealed using appropriate pipe threads and sealant to maintain system pressure.
Does this switch require external power to operate?
No, this is a mechanical, non-inductive controller that operates based on thermal expansion and contraction. It does not require a separate power supply for its internal switching mechanism.
