Jiulong WYH 90/322 (0-90°C) Double Contact Spiral Thermostat

Jiulong WYH 90/322 Double Contact Spiral Thermostat: Reliable Control in Heating Systems

Jiulong is a manufacturer of quality control equipment for industrial and residential applications. The Jiulong WYH 90/322 Dual Contact Spiral Thermostat is an advanced spiral thermostat designed to monitor and safely manage fluid temperature in heating systems, boilers, hot water heaters, or other applications requiring temperature control.

What is a Double Contact Spiral Thermostat and How Does It Work?

A spiral thermostat (capillary) operates on the principle that a liquid or gas at the tip of a heat-sensitive probe expands and contracts with temperature. This expansion/contraction is transmitted through a tube (spiral) to a switch inside the thermostat, which then opens and closes an electrical circuit.

"Double Contact" indicates that the Spiral Thermostat has contacts that can operate at two different temperature setpoints or control two different circuits (for example, activating an alarm while simultaneously activating a pump). This is a significant advantage in terms of safety and automation.

Spiral Thermostat Main Functions:

• Temperature Control: Continuously monitors the fluid temperature and keeps it within set values.

• Automatic Control: Opens or closes a contact when the set temperature value is reached, thus controlling a heating element, pump or valve.

• Safety and Warning: Thanks to a second contact, it can trigger alarm circuits when the temperature reaches an undesirable level.

Highlights and Advantages of Jiulong WYH 90/322 Spiral Thermostat:

• Temperature Range (0-90°C): This wide range is ideal for heating systems, combi boilers or process cooling applications.

• Dual Contact: Thanks to two independent contacts, it offers the flexibility to manage both main control and a safety or warning circuit with a single device.

• Durable Structure: The body made of high-quality materials provides resistance to humid and harsh environments.

• Wide Application Area: Can be used in many areas from boiler rooms to hydraulic power units and heat exchangers.

• Easy Installation: It can be easily integrated into the installation or equipment with standard connection dimensions.

• Reliability: High-quality mechanical and electrical components ensure long-lasting and trouble-free operation.

Spiral Thermostat Usage Areas:

• Heating Boilers: Control of boiler water temperature.

• Solar Energy Systems: Controlling the temperature of water coming from solar panels.

• Boilers: Adjusting the water temperature in hot water boilers.

• Building Automation: As a temperature sensor for automatic pump and valve control.

• Industrial Processes: Monitoring and control of fluid temperature.
