Cooling coils are used to control temperatures in material processing and heating/cooling systems. Heat exchange occurs as materials move through the coil, with longer coils promoting more heat loss. Coils can be actively pumped or use density differences to circulate materials. Maintenance is important to prevent reduced circulation and leaks. A cooling coil is a […]
A solenoid coil is a wire wound tightly around a conductive core with a hollow center, creating an electromagnet used for linear motion to switch or drive devices. They can be replaced if damaged, but some are sealed, like automotive starter solenoids. A solenoid coil is a wire wound tightly around a conductive core with […]
Heating elements come in many shapes and sizes, including heating coils made of ceramic or metal that are heated by electric current. They are found in hair dryers, stoves, ovens, portable heaters, and water heaters. Heating coils produce fast and efficient heat but consume large amounts of electricity. Baseboard heaters use a similar design with […]
HVAC systems have two coils, a condenser coil in the outdoor unit and an evaporator coil in the indoor unit. The compressor extracts hot refrigerant gas and cools it in the outdoor coil, while the liquid refrigerant is cooled and expanded in the indoor coil to cool the air. In winter, the process is reversed […]
Coil springs are cylindrical or cone-shaped devices with varying numbers of coils used to absorb impact or resist compressive or tensile forces. They are made of specially hardened wires and can be used as compression or tensioning elements, or for percussive impact in various applications. A coil spring is a coiled mechanical device that stores […]
Condenser coils transfer heat between two mediums in heating and cooling systems, such as air conditioning units. They are self-contained but may require replacement over time. It’s important to hire a professional to replace the coil and dispose of the old unit properly. A sign of a problem is when cooled air is hotter than […]
The Rogowski coil is a device used to measure alternating or high-speed electric currents. Its unique design includes an air core and evenly spaced wire winding. It is used in many industries but faces competition from cheaper and lighter sensors using similar technology. A Rogowski coil is a simple device used to measure alternating current […]
Coil packs are used in automotive distributorless ignition systems and perform the same function as traditional ignition coils. Each coil pack can be separated or combined into a single unit and is usually activated by an electronic control unit or ignition module. Distributorless ignition systems eliminate the need for a distributor and rotor system and […]
Moving coil actuators use electromagnetic force to control motion for secondary mechanisms. They differ from solenoids as the coil moves within an array of static magnets, producing bi-directional motion. They can be configured to produce linear and rotary outputs and can be part of a servo system. A common use is in computer hard drives […]
A solenoid valve coil uses a wire wound around a ferromagnetic core to create a magnetic field that moves a valve plunger. It can operate on different voltages and is available in various constructions. Different configurations include tape-wrapped, encapsulated, and connector types. A solenoid valve coil, which typically has copper or aluminum wire, is often […]
Coil spring compressors are essential tools for safely servicing automotive suspensions with struts, which combine a shock absorber and spring into one component. The tool removes stress from the strut assembly, allowing for safe disassembly and reassembly. Attempting to remove a strut assembly without a compressor is dangerous and impractical. Coil spring compressors are tools […]
Coil springs are cylindrical metal or plastic shapes used for shock absorption and stress reduction in various products, including beds, sofas, doors, and trampolines. They are made of heavy metal and can wear out over time, needing replacement. Coil springs are commonly used in the automotive industry and can be made of light metals for […]
Coil actuators are electromagnetic devices that move objects quickly and stop on demand. They come in various types and sizes and are used in consumer electronics, manufacturing assembly lines, medical equipment, and computer hard drives. Moving coil and rotary spool/wishbone actuators are the simplest types. They are also used in speakers and medical equipment to […]
A charging coil compensates for signal losses in telephone lines by inducing an electric current via magnetic fields. They are placed every 6,000 feet and reduce electrical losses at high frequencies. Coils are based on pupin coils and capacitance is defined by the length of the cable conductor. Inductance helps equalize losses along a vocal […]
Heating coils are electrical devices used to heat air or water. They come in various designs and are used in appliances such as ovens, dryers, and heaters. The amount of heat produced is controlled by a rheostat switch, and safety switches are incorporated to prevent fires. A heating coil is a device used to heat […]
Galvanized steel coil is a versatile material used in manufacturing and production environments. It is thin enough to be rolled into a coil or cut to any length or shape needed. Its natural ability to prevent rust or corrosion makes it ideal for outdoor applications, such as roofing and building elements. It can also be […]
An electromagnetic coil consists of a conductor and a core, commonly made of copper wire and metal. It stores energy in its magnetic field and is measured in units of Henry. Coils must have terminals connected to the wire, and when two are placed together, it is called a transformer. Electromagnetic coils are also used […]
The tesla coil, invented by Nikola Tesla, creates big sparks and can wirelessly power a fluorescent lamp. It consists of two coils and capacitors to store energy for discharge. Building and observing tesla coils is a popular activity among science enthusiasts. The largest tesla coil in the world produces 1.5 megavolts of current and 20-foot […]
Coil binding machines punch, insert a coil, and fold and trim the ends to bind 90-300 pages. Dual coil binders can be separate or all-in-one machines, while plastic comb and plastic coil binding machines offer easy editing and flat documents. Coil binding machines bind documents by lining up pages, punching, inserting a coil, and then […]
Plate coils are flat metal plates welded together with a fluid flow channel between them to absorb or diffuse heat energy. They offer larger heat radiating surfaces, flexible shaping, and space-saving features. The plates can be rolled into cylinders as small as 12 inches in diameter, making them a flexible and efficient heat transfer option. […]
