Thermostat Single Pole 50-300°C: Robust Manual Temperature Control with 1.5m Capillary

Precise Temperature Management for High-Heat Catering Applications

Consistent and accurate temperature control is vital for the performance, safety, and longevity of your commercial catering equipment. For appliances like fryers, ovens, and griddles, precise heat regulation ensures optimal cooking results and prevents costly damage.

This Single Pole Thermostat provides a simple yet highly effective way to manually manage temperatures across a demanding range of 50°C to 300°C. It's engineered to work seamlessly with high-heat catering and immersion-type heating elements, making it ideal for equipment where higher temperatures are required. Thanks to its generous 1.5-meter liquid-filled sensing capillary, this thermostat delivers reliable and responsive temperature detection. Easy to install and dependable, it's a fundamental component for maintaining consistent heat in your busiest kitchen environments.

Key Features & Benefits

• High Temperature Control Range: Manually adjust temperatures from 50°C to 300°C, perfectly suited for fryers, ovens, griddles, and other high-heat appliances.

• Responsive Liquid-Filled Sensing Bulb: Operates via a special liquid-filled sensing bulb connected to a 1500mm (1.5m) capillary, providing accurate and rapid temperature change detection.

• Robust Electrical Ratings: Capable of handling 250Vac and up to 16A, making it suitable for a broad range of standard catering and immersion heating elements.

• Standard Faston Tab Terminals: Features reliable faston tab terminals for straightforward and secure electrical connections.

• Simple & Effective Control: Offers a basic, intuitive method for operators to manually adjust and maintain desired temperatures.

• Durable Construction: Built to withstand the rigorous demands of commercial kitchen environments, ensuring longevity and consistent performance.

• Optional Accessories Available: Knobs and bezels are available as optional accessories, allowing for customisation and a professional finish (sold separately).

• Associated High Limit Thermostats: We also supply compatible high limit thermostats as associated accessories, offering an essential additional layer of safety (sold separately).

How a Single Pole Capillary Thermostat Works

A single pole capillary thermostat functions on the principle of thermal expansion. A liquid-filled sensing bulb, connected to the main thermostat body via a thin capillary tube, is strategically placed where temperature control is needed (e.g., within a fryer oil tank or oven cavity). As the temperature of this area fluctuates, the liquid inside the bulb expands or contracts. This change in volume creates pressure within the sealed capillary system, which is then transmitted to an internal bellows or diaphragm within the thermostat's main body.

This mechanical movement actuates a single pole electrical switch (16A, 250Vac). When the temperature reaches the pre-set point on the thermostat's dial, the switch either opens (breaking the circuit to a heating element) or closes (completing the circuit), thereby controlling the flow of power and regulating the temperature.

Important Installation & Safety Notice

Installation and wiring of this thermostat must ONLY be performed by a qualified and licensed electrician or appliance technician in strict accordance with all local electrical codes, safety regulations, and the appliance manufacturer's instructions. Always ensure the main power supply to the circuit is disconnected and locked out before any work is carried out. Improper installation can lead to electrical shock, fire, equipment damage, or void its warranty. Ensure the sensing bulb and capillary are correctly positioned to accurately reflect the temperature being controlled.

Frequently Asked Questions (FAQs)

Q1: What types of equipment is this 50-300°C thermostat best for?

A1: This thermostat is ideal for catering equipment requiring higher temperatures, such as commercial deep fat fryers, ovens, griddles, hot plates, and some types of boiling pans or immersion heaters.

Q2: What is the benefit of the 1.5-meter capillary?

A2: The long capillary allows the temperature-sensing bulb to be positioned precisely within the heat zone (e.g., in the fryer oil, oven cavity), while the main thermostat body and control shaft can be conveniently mounted on the appliance's exterior control panel for user access.

Q3: Are the knob and bezel included with the thermostat?

A3: No, the knobs and bezels are optional accessories and are sold separately. This provides flexibility for you to choose the style that best matches your equipment or to simply replace the thermostat without needing a new knob if your existing one is still functional.

Q4: Can I use this thermostat for temperatures below 50°C?

A4: This thermostat is designed and calibrated for its 50-300°C range. For lower temperature applications (e.g., 30-110°C for hot cupboards), we offer a full range of single-pole thermostats with different temperature capabilities to suit your specific needs.

Q5: Why might I need a separate "high limit thermostat"?

A5: A high limit thermostat acts as a critical safety backup. It's a non-resettable or manually resettable device that trips and cuts power if the temperature exceeds a dangerous upper limit, protecting your equipment from severe overheating and preventing potential hazards in case the primary control thermostat fails. We can supply these as associated safety accessories.
