Bimetal Thermostat

A: Bimetal Thermostats use two different kinds of metal to regulate the temperature setting. When one of the metals expands more quickly than the other, it creates a round arc, like a rainbow. As the temperature changes, the metals continue to react differently, operating the thermostat.

A: Common temperature ranges are from 20 to 300 ° C. They are current sensitive or insensitive depending on models. Models with current sensitive bimetal or heated by a resistance, are used in energy regulators.

A: A common application of a bimetallic strip is in thermostats, which control the temperature in a room or a device. When the room temperature changes, it causes the bimetallic strip in the thermostat to bend. This bending action can be used to actuate a switch that controls the heating or cooling system.

A: Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contact us for further information.

A: A bimetallic strip is made of two different kinds of metals that are laminated into one strip. Each metal responds to heat and cold by expanding a specific amount based on the change in temperature. When heat is applied to the coiled bimetallic strip, it expands and uncoils.

A: Pull off the thermostat cover and set the thermostat to a few degrees above room temperature. Slip the wrench onto the nut behind the coiled bimetallic element, hold the dial firmly, and turn the wrench until the mercury breaks contact. (The direction you'll need to turn the nut varies between models.)

A: Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website.

A: The two strips are joined together inseparably and thus form the bimetal strip. When the temperature changes, the different metals expand to different degrees, which leads to a mechanical deformation of the bimetal strip. This mechanical deformation can be detected in a rotary movement.

A: A “bimetal” is a thermostatic element composed of two dissimilar metal plates bonded together. These dissimilar metals have different thermal expansion coefficients and when subjected to a change in temperature, the element begins to deform.

A: Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.

A: Most car thermostats are rated to begin opening between 180 and 195 degrees and will reach the fully open position around 20 degrees higher, allowing coolant to flow between the radiator and engine.

A: The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also most expensive way. By seafreight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way. Please contact us for further information.

A: For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all cases we will try to accommodate your needs. In most cases we are able to do so.

A: Cost : Bimetallic thermostats are cheaper than electronic thermostats and are much more reliable because they rely on mechanical operation. Reliability and accuracy : Bimetallic thermostats are simple mechanical devices that do not require energy to operate, so they are very reliable and less prone to failures.

A: A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.

A: You can make the payment to our bank account, Western Union or PayPal:
30% deposit in advance, 70% balance against the copy of B/L.

A: A bimetallic strip consists of a strip of two different metals welded together. When we heat it, different metals expand by different amounts. It bends due to thermal expansion. Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.

A: We warranty our materials and workmanship. Our commitment is to your satisfaction with our products. In warranty or not, it is the culture of our company to address and resolve all customer issues to everyone’s satisfaction.

A: Now, the only operating mechanism for the movement of a bimetallic strip is the application of heat — the two metal strips are joined together, and the bending is caused by the difference in thermal expansion coefficients of the two metals.

A: Yes, we always use high quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.
