Just like all kinds of appliances and electronic devices out there, an HVAC system is comprised of so many various parts and components. Some of these parts and components are easily overlooked, such as the copper components and bolts and other fittings. But on the other hand, there are also other components that are instantly noticeable at first glance — like filter driers, compressors, and condensers. Another perfect example of this kind of HVAC component is the capacitor.
What Is A Capacitor?
Essentially speaking, a capacitor is a device that stores electrical energy in an electrical field. It is formerly known as a condenser or condensator, and it is a passive electronic component with two terminals.
The effect of a capacitor is known as capacitance. Whereas some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component that is designed to add capacitance to a circuit.
Practical capacitors come in a wide variety in terms of physical form and construction. That said, most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces that are separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. Meanwhile, the nonconducting dielectric acts to increase the capacitor’s charge capacity, and materials commonly used as dielectrics include glass, ceramic, plastic film, paper, and oxide layers. Long story short, capacitors are extensively used as parts of electrical circuits in many common electrical devices, such as HVAC systems.
Because of that, it is not surprising that capacitors are required for HVAC systems. And so, as an HVAC professional, it is your responsibility to make sure that the HVAC systems you’re offering to your customers are equipped with high-quality capacitors. In order for you to be able to fulfill this responsibility, you must first need a reliable manufacturer or wholesale supplier of capacitors to work with you.
Fortunately, there are a lot of these manufacturers and wholesale suppliers out there. You can particularly find a number of them in the United States alone. And so, if your HVAC business is based in the U.S. and you’re looking for a manufacturer or wholesale supplier of capacitors, here are ten companies that you can start looking up.
