Magnetic coils and yokes, demagnetizing coils and yokes, and other search coils, etc.

Magnetic coils and yokes, demagnetizing coils and yokes, and other search coils, etc.

A unique item tailored to your needs!

The magnetic yoke and air-core coil are designed to set permanent magnets or permanent magnet products, converting the large pulse currents flowing from the capacitor-type pulse power supply and the magnetizing power supply into a magnetic field. This magnetic field imparts magnetism to the permanent magnets. If this design is defective, even if a high-performance magnetizing power supply is purchased, it may reduce the performance of the magnetic yoke by half. Our company utilizes its abundant technology and experience to design the most rational magnetic yokes and coils. Additionally, we provide designs tailored for search coils, search yokes, Helmholtz coils, and solenoid coils.

Discharge Coil (Current Transformer CT) "KBN"

Discharge Coil (Current Transformer CT) "KBN"

A product that discharges electric charges to protect electrical equipment! Please use it first. A new world will open up! Instruments for distribution boards, control panels, distribution panels, and panels.

KBN is our discharge coil. It is connected in parallel with a large-capacity three-phase capacitor installed for automatic power factor compensation of the receiving equipment. After the capacitor is turned off, it discharges the residual charge in a short time, reducing charge collisions when the capacitor is turned on/off, thereby protecting nearby electrical equipment. For inquiries, please contact "lightstar_1979@yahoo.co.jp".

"Air conditioning units can also reduce costs through renovations" *Basic knowledge materials on heat exchangers are also being provided.*

"Air conditioning units can also reduce costs through renovations" *Basic knowledge materials on heat exchangers are also being provided.*

Low-cost repairs by replacing only the cooler/heater coil that has caused water or steam leaks! Design and manufacturing of the air conditioning unit itself is also possible. Nationwide travel available.

At Katsukawa Thermal Engineering Co., Ltd., we offer "renovation of air conditioning units (AHU)" by replacing only the coils inside the air handling units (AHU). Unless the entire air conditioning unit is significantly aged, the AHU itself can continue to be used by simply replacing the coils, which allows for substantial cost savings on repairs. We also accept orders for the new manufacturing of air conditioning units (AHU). 【Features】 ■ Cost reduction through coil replacement of high-cost equipment such as air handling units and air conditioning units ■ Nationwide service available ★ For more details, please check the catalog available for download as a PDF. We are also providing materials that introduce basic knowledge about heat exchangers, their types, and their roles in the manufacturing line.
