[Cost Reduction and Longevity Related Case] Cold Water Coil

[Cost Reduction and Longevity Related Case] Cold Water Coil

Updated the air conditioning coil! Successfully extended its lifespan while keeping costs down by utilizing the main unit and ducts.

At the food factory, the chilled water coil of the air conditioning unit has corroded and started leaking, necessitating urgent repairs. Our company had a custom chilled water coil manufactured by the air conditioning unit manufacturer to fit within the main unit. As a result, we were able to utilize the main unit and ducts as they were, significantly reducing costs compared to a complete replacement. 【Case Study】 ■Issues - The corrosion of the coil has progressed to a point where partial repairs such as welding are not feasible. ■Proposal - Custom manufacturing of a chilled water coil by the air conditioning unit manufacturer to fit within the main unit. - Conducted multiple simulations of the loading and unloading process through discussions with the customer. *For more details, please refer to the PDF document or feel free to contact us.

Coil - Air-core coil

Coil - Air-core coil

Unlike winding coils that are wound around bobbins and similar spools, the wire materials are bonded together to maintain the coil shape using only copper wire.

Air-core coils, unlike winding coils that are wound around a bobbin or similar frame, maintain their coil shape solely with copper wire, with the wire materials bonded together. Therefore, they are often used in electronic devices that require space efficiency, compact size, and high performance. On the other hand, the material costs for the wire are generally high, and the winding machines also need to be specialized, making air-core coils more expensive compared to bobbin-wound winding coils.

Miniaturization! × Cost Reduction! Flat wire coils rolled with unique technology.

Miniaturization! × Cost Reduction! Flat wire coils rolled with unique technology.

Achieving compact motor size! Cost reduction through thinner magnets! We support everything from prototype to mass production of flat wire multilayer coils!

Using our unique winding method at Nitto Electric Co., Ltd., we produce high-density, space-saving rectangular wire coils with our in-house winding machines! We can accommodate customer needs from small to large-scale production. In traditional rectangular wire (ribbon wire), there were various inconveniences such as "we can't do fine adjustments to wire dimensions like thickness and width in-house!" and "the unit price is high!" Our company has successfully rolled round wire into rectangular wire using our unique technology. By performing these rolling processes within the same operation as winding, we significantly contribute to the mass production of aligned wound coils and the improvement of packing density, enhancing cost performance. 【Features】 ★ The rolling process is completed within the same operation as winding. ★ Cost reduction is possible due to the thinness of the magnets. ★ Compact motor sizes are achieved due to high packing density. ★ We can accommodate prototype to mass production with lot sizes tailored to your requests. ★ Compatible with copper wire, wire diameters from 0.045 to 0.25.

Electromagnetic coil [Solenoid round wire (bobbin type)]

Electromagnetic coil [Solenoid round wire (bobbin type)]

Size: Approximately 5mm to 1200mm, compatible wire size: φ0.012 to φ3.2

The product is a coil designed to generate a magnetic field when electric current flows through it. The winding coil has a shape where a conductor (copper wire) is wound, and when current passes through it, a magnetic field is generated within the coil. This magnetic field is determined by the shape of the coil, the number of turns, and the current, which define the specifications of the electromagnetic coil. Please feel free to contact us for the development of custom-made products, lead wire installation, lead wire processing, protective tape, unit assembly, circuit board production, etc. *For more details, please refer to the related links or feel free to contact us.*
