The supercapacitor "Supercon" can be easily installed by simply adding it to the outdoor unit, requiring no maintenance or running costs, and contributes to reducing annual electricity consumption. It can be used for both cooling and heating. There are records of achieving approximately a 10% reduction in annual electricity consumption through installation. 【Features】 ■ Compatible with old commercial air conditioning outdoor units in offices, stores, and factories ■ Extensive implementation track record with major companies ■ No maintenance or running costs required ★ If the nameplate sticker indicates refrigerant R22 or R410A, there is room for replacement. * For more details, please refer to the materials. Feel free to contact us as well.

According to a public opinion poll by Germany's public broadcaster ARD, environmental and climate change measures rank first at 33%, followed by immigration at 22% and the novel coronavirus at 18%. As stated, climate change measures have become a significant global goal. There are approximately 10 million commercial air conditioning units operating in Japan. Therefore, we propose reducing CO2, GWP, and power consumption for these widely used air conditioning units. The "Super Computer" we handle can be easily added to the outdoor units of air conditioners, allowing for energy savings without relying on discomfort or control, and it is usable for both cooling and heating. By improving heating and cooling efficiency and achieving CO2 reduction and energy savings, it can provide an effect of about 8-10%. For more details, please refer to the related catalog. 【Features】 ■ Easy installation ■ No running costs ■ No maintenance required ■ Hybrid system reduces annual power consumption by about 20% ■ Main unit installation reduces annual power consumption by about 10% *For more details, please refer to the PDF materials or feel free to contact us.

If the refrigerant name "Refrigerant R22" or "Refrigerant R410A" is indicated on the nameplate sticker attached to the outdoor unit, there is a possibility for refrigerant replacement, so please consider it. By replacing the refrigerant (which may include the simultaneous installation of a supercomputer in some cases), it contributes to the reduction of greenhouse gases and helps combat global warming. Furthermore, as power consumption decreases, electricity costs will also be reduced. 【Features】 ■ In the case of Refrigerant R22 - By completely replacing with refrigerant HB156 and using a supercomputer, power consumption is reduced by 20%. ■ In the case of Refrigerant R410A (varies depending on the horsepower of the air conditioner) - Under 10 horsepower → By completely replacing with refrigerant HB366, power consumption is reduced by 15%, no supercomputer installation required. - Over 10 horsepower → By replacing 30% with refrigerant HB266 and using a supercomputer, power consumption is reduced by 20%. * The rate of power consumption reduction may vary due to aging of the air conditioning equipment, etc. * For more details, please refer to the PDF document or feel free to contact us.

By monitoring the strong current operation of the brake circuit (strong/weak excitation switching type) for a specified time, it prevents abnormal heating and combustion of the brake coil due to Joule heating. Furthermore, daily current measurements indicate the first step towards trend management of coil insulation deterioration caused by strong current flow. 【Features】 ■ Real-time current measurement ■ Easy setup and history check via touch panel ■ Alarm activation for overcurrent detection *For more details, please contact us or refer to the catalog.

There are many types of silver solder used for brazing. Choosing the optimal silver solder according to the required performance, durability, and cost of the product is important for creating a good product. Daiichi Electric, as a metal professional, is particular about material selection. While it is possible to create high-quality products without considering cost, that would not fulfill the needs of our customers. Daiichi Electric is committed to selecting the "optimal" materials. We always make feasible proposals and prioritize our customers' needs. 【Features】 ■ Selecting the optimal solder according to durability ■ Selecting the optimal solder according to cost ■ Assessing the compatibility of materials ■ Making the impossible possible. *For more details, please contact us or refer to our catalog.

There are two main methods for brazing: "torch brazing" and "high-frequency brazing." Torch brazing involves working with a gas torch in hand, where precise hand movements and flame control determine the quality of the product, requiring a very high level of skill and craftsmanship. With the right technique, torch brazing offers a high degree of freedom in production and holds infinite possibilities. 【Features】 ■ Selection of the optimal brazing material based on durability ■ Selection of the optimal brazing material based on cost ■ Assessment of compatibility between materials ■ Making the impossible possible. *For more details, please contact us or refer to the catalog.

Copper materials are supplied in the form of round bars or flat plates. Since there are products suitable for each shape, the choice of material shape depends on the product. Because round bars and flat plates differ significantly in shape, it is often necessary to find and request a factory that performs the relevant processing. Daiichi Electric, which specializes in copper processing, handles both round bar and flat plate materials. We support processing and sales for both, so please consult us for any copper processing needs. Not only copper, but many metal materials are expensive. Since Daiichi Electric directly trades with metal manufacturers, we can sell only the necessary quantities to our customers. Even with expensive materials, we deliver optimal products without waste. 【Features】 ■ Available from a single piece ■ Supports both round bars and flat plates ■ One-stop integrated production *For more details, please download the PDF or contact us.
