water heater exchanger Water heating coil description Water heating coils are a type of heat exchanger often called hydronic coils that use hot water from a boiler to heat or remove moisture from the air. The air moves through the fins of the coil which is hot from water flowing through the tubes. This is a type of heat exchanger mostly used in commercial and industrial air handler units, roof top units as well as ductwork installations downstream. In parts of the country and world, you may be more familiar with radiant heat or baseboard heat. Those particular units do not have air moving through them but simply radiates the air near the units. Hot water coils on the other hand are used in forced air systems and booster coils or reheat coils are used in ductwork downstream to reheat the air that has cooled off. Water heating coil manufacturing process Fins——Expansion——Casing——Brazing or welding——Testing——Crating The cold machining process of fins provides excellent mechanical resistance , fins are strong and have strong resistance to atmospheric corrosion, etc. The pressure required to extrude the fin from the aluminum sleeve creates an excellent “pressure bond” between the two materials. In addition, the aluminum finned material completely surrounds the metal of the tube, so there is no risk of electrical corrosion at the fin root (between the tube and the fin). All of these advantages ensure the most stable performance over time of all other fin types. Water heating coil maintainance The heated liquid does not contain substances that should not corrode the components. During use, the scale or carbon on the pipe surface should be removed frequently, otherwise it will affect the efficiency and life of the components. The working voltage of the heating element shall not exceed 1.1 times of its rated value, the ambient humidity shall not exceed 95%, and the shell shall be effectively grounded. The electric heating element of the water heating pipe should be stored in a dry place. If the insulation resistance to the ground is lower than 1M? due to long-term storage, it can be dried in an oven at about 200? for several hours to recover. When tightening the main thread of the water heating pipe, do not use excessive force on the terminal. Water heating coil applications Booster heat, reheat, waste heat reclamation, pre-heat, fluid process heat and more.

coils in ac unit How does condenser coil works While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid. What’s the Difference Between A/C Condenser coil and Evaporator Coils? Extracting indoor heat from the air and adding it to refrigerant is the function of the evaporator coil. Installed inside the indoor air handler, the evaporator is continuously exposed to the flow of warm air drawn by the system blower from individual rooms in the house through return ducts. Refrigerant circulating through copper tubes in the coil is a cold vapor around 40 degrees. In this state, the heat-absorbent properties of the refrigerant are maximized. Heat energy from the warm house airflow transfers through the chilled copper coil tubing and is readily absorbed by the refrigerant flow. With its heat energy extracted by the coil, the cooled airflow is pushed by the blower into the supply ducts and dispersed throughout the house. At the same time heat is being extracted, the warm air contacting frigid evaporator coil surfaces triggers condensation, which lowers the humidity level in the airflow, “conditioning” the air just as Willis Carrier designed over a century ago. After leaving the evaporator coil, refrigerant flows through an insulated conduit to the outdoor A/C component that’s usually directly behind the house. This cabinet contains both the compressor and the condenser coil. Refrigerant entering the compressor is pressurized, concentrating the molecules of heat energy and raising the temperature of the refrigerant vapor to over 100 degrees. This superheated state ensures efficient transfer of the heat energy into outdoor air, even when the outdoor temperature is high, such as on a hot summer day. The condenser coil is of similar design to the indoor evaporator coil. However, the difference between A/C evaporator and condenser coil is exactly reversed. While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid. As the refrigerant releases its heat load, a fan incorporated in the unit blows air through the condenser coil passages and heat is dispersed into outdoor air. High-pressure liquid refrigerant leaving the condenser coil makes a u-turn and flows back to the evaporator coil. An expansion valve before the evaporator restricts the flow of refrigerant, forcing it through a narrow orifice and converting it back to a vaporized state, ready to absorb more heat energy from your home.

U bend tube applications In various bends, various bends are inevitably used, such as marine pipelines, automobile oil pipes and other pipelines. Compared with other types of elbows, the arc elbow has many advantages. First, all kinds of materials flow smoothly at the arc elbow, and the impact force on the pipe wall is small and uniform; secondly, the arc elbow itself has less stress concentration. Strong and high impact resistance; With the rise of modern steel furniture, office chairs, beach chairs, luggage carts, shopping carts, children’s trolleys, cribs, computer tables, etc., several metal tubes form several bright lines, which are practical, convenient, safe and reliable ; Air conditioning refrigeration pipes mainly include elbows, small U-shaped pipes, return elbows, etc.; The bathroom industry now has more and more bends, faucets, towel racks and S-shaped accessories. Motorcycles, automobiles, electric vehicles, bicycles and other vehicles, handlebars, bumpers, frames, etc.; Fitness equipment, lighting, construction machinery and other industries.

coil tube Stainless steel coil applications Stainless steel coils are widely used in chemical, machinery, electronics, electric power, textiles, rubber, food, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields. Industrial stainless steel coils: heat exchangers, boilers, petroleum, chemicals, fertilizers, chemical fibers, pharmaceuticals, nuclear power, etc. Stainless steel coils for fluids: beverages, beer, milk, water supply systems, medical equipment, etc. Stainless steel coils for mechanical structures: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, construction and decoration, etc. Bright stainless steel coil: welded with stainless steel strips, then reduce the wall, reducing the wall thickness from thick to thin. This process can make the wall thickness uniform and smooth, and the reduced-wall stretched tube wall forms a weld-free effect. According to the naked eye, it is a seamless pipe, but its process is determined to be a welded pipe. The process of wall reduction is accompanied by bright annealing, so that the inner and outer walls will not form an oxide layer, and the inner and outer walls are bright and beautiful, which is really needed for medical products. The next process requires sizing, that is, the process of large and small drawing, to determine the outer diameter, the outer diameter tolerance can generally reach plus or minus 0.01mm.
