Wax Thermostatic Element Principles And How It Works

by | Apr 8, 2022 | HVAC

Wax thermostatic element is a tool that is applied in shipping, plumbing, agriculture, cooling system, sanitary, military, and so on. This tool has many types. Each type has a task from slight to heavy task. Primarily, the wax thermostatic element changes heat into mechanical energy. After that, there are some processes you need to know before you buy it for your home. It is necessary for you to know the wax thermostatic element principles. Knowing this will help you to apply the wax thermostatic element for your needs.

1. Wax Thermostatic Element Principles

As we know, the wax thermostatic element expands at high temperatures, and the increasing temperature will change into mechanical energy. The rubber and expanded shell helped this process begin. It will push the road and move under the pressure of expansion. This process will make a displacement, so the turn-off and turn-on functions will be automatically done. Although the wax thermostatic element is small in volume, it is fast in responding to the speed. 

The range temperature of the wax thermostatic element is about 30 to 300 Fahrenheit. And with the rate of expansion is about 1% to 25 %. The working principle of this tool is based on converting heat become mechanical energy through thermal expansion accurately; this process will be started when they melt.

2. The Automotive Thermostat In Engine Cooling System 

The Wax thermostatic element has an automotive thermostat in the engine cooling system. What does it mean? It means that when the temperature increases, it will make the material melt. The effect of this point is it will push the rod of the cylinder and open the valve. That is the simple explanation of the automotive thermostat.

Actually, what is the thermostat in an automotive engine? The thermostat is a liquid in the car engine which has a small device. It is located in a radiator and engine. This is about 2 inches, or we can say 5 cm. The work of the thermostat is to block the coolant flowing to the radiator until the engine becomes hotter. You need to know that no coolant flows if the engine is in cold condition. When the engine is in 200 degrees Fahrenheit or 95 degrees Celcius, the thermostat will open. If we let the engine increases the temperature, the thermostat will decrease emissions, deposits, and engine wear. 

There is a secret to the working system of the thermostat itself. Why does the thermostat lie in the small cylinder? It is because of the cylinder content of wax. This wax will become melted at 180 degrees Fahrenheit. This wax is connected to the valve, and the valve is connected to a rod. When the wax becomes melted, it spreads significantly and directly pushes the road and opens the valve. 

This working system is also used in skylights and greenhouse vents. The simple thing that makes a difference is that these devices melt the wax at lower temperatures than the automotive thermostat in the engine cooling system.

Well, you know about the wax thermostatic element principles and how it works. Now, you can imagine what you choose for your needs.

3. Patented Technology

After you have known the explanation about knowing the wax thermostatic element principles, now it is time for you to buy a wax thermostatic element. Some products are in patented technology. What does it mean? Patented technology means that every product has its accuracy and sensitivity tested. Besides, it proves its high-quality material and sensitivity, so you can easily set the temperature in your room. Make sure to check their certificates and working results.

4. The Solution In Applying Wax Thermostatic Element Principle

Sometimes we don’t know how to apply our product, wax thermostatic element. If you have difficulties with the parameter of the wax thermostatic, you could consult with some suppliers and confirm the information about the wax thermostatic element. The valuable information is working stroke, temperature range, and maximum load. Knowing these three pieces of information will help to apply the wax thermostatic element.
