Portable generator (4.5kVA)

Portable generator (4.5kVA)

A portable hybrid generator that uses LP gas or gasoline as fuel and has a smaller capacity compared to stationary models.

This is a product that is desirable to have for securing power during a power outage. If it is a fixed installation type, it takes up space due to concrete laying, and I don't think everyone has a large area. In such cases, this portable generator is recommended. When not in use, it can be stored in a warehouse and taken out for use during a power outage. It is certainly not light, but it has a handle, making it possible to carry it like a cart. Additionally, this generator is a hybrid type that allows you to choose between gasoline or LP gas as fuel. If you find gasoline to be corrosive and the regular replacement cumbersome, you can consult with a gas contractor to connect gas and supply fuel from the LP gas available at your home. With a capacity of 5kVA, it is ideal for securing power where a large capacity is not needed for single-phase power sources (100V or 200V). Depending on usage conditions, it can operate for about 30 hours on a single 50kg gas cylinder, so with proper fuel supply, it is possible to secure a 72-hour lifeline. It is lighter than the existing "S-5500" and excels in quietness. Compared to fixed installation types, it is also reasonably priced, so please consider it.

[Processing Example] Hydroelectric Power Generation Device

[Processing Example] Hydroelectric Power Generation Device

We designed and manufactured it with a simple structure that can be repurposed for irrigation channels with different conditions!

We would like to introduce a case study of the processing of hydropower generation equipment conducted by Takakawa Industrial. As part of a collaborative project with a university, we manufactured a small hydropower generator for an irrigation channel. While manufacturing at large companies typically incurs excessive costs, we leveraged the strengths of a small factory to propose a VAVE (Value Analysis/Value Engineering) solution. We designed and manufactured a simple structure that can be repurposed for irrigation channels with varying conditions. Additionally, we have a case study of designing and manufacturing a custom 7-meter stainless steel kitchen at a coworking space in Ueda City. [Case Study of Hydropower Generation Equipment] ■ Industry: Industry-Academia Collaboration ■ Material: SPCC and others ■ Plate Thickness: Various ■ Size: 1200×1200×800 ■ Delivery Time: 1 month *For more details, please refer to the PDF document or feel free to contact us.

Generator capable of continuous operation for long hours | Portable generator 【JPG2600】

Generator capable of continuous operation for long hours | Portable generator 【JPG2600】

[Many case studies] ■ Portable generator with tank-specific body type for long hours of operation / ■ Reliable soundproof design

The production and sales of JPG2600 have ended, but we continue to accept inquiries regarding maintenance, parts, modifications, and selection. Please feel free to contact us. [Many case studies available] It is possible to operate disaster response equipment stably for long periods! With reliable sine wave output, it can also be used as a power source for electronic devices such as communication equipment. The generator does not have a gasoline tank inside; instead, it uses an external dedicated one-touch fuel tank (compliant with fire safety regulations), allowing for long operation times and reducing the workload associated with handling leftover fuel after use. A specially designed engine oil sub-tank (patent pending) that allows for refueling while the engine is running has been added inside the generator. By increasing both fuel and engine oil capacity, long operation times have been made possible. In addition to soundproof design (certified as ultra-low noise construction machinery by the Ministry of Land, Infrastructure, Transport and Tourism), it allows for frequency switching between 50Hz and 60Hz. The design considers portability, and no tools are required for connecting or disconnecting each part, making assembly easy. *For more details, please contact us or download the PDF to view.

Cross-flow turbine for small hydropower generation

Cross-flow turbine for small hydropower generation

We offer custom-designed cross-flow turbines tailored to the site’s head and flow rate at a low price. We also accept orders for the sale of the turbine alone.

【 Features 】 - Equipped with a flow adjustment mechanism (guide vanes). - Simple structure, making maintenance easy. The dimensions of the water turbine (diameter, width) are determined based on the flow rate and effective head. After that, a prototype is manufactured, and trial operations are conducted in a hydraulic environment similar to the actual site to confirm power generation performance. Our company has a dedicated water tank for the development of small hydropower generation systems. We use up to three 55 kW pumps as flow generation devices, combined with a 55 kW generator to conduct performance verification tests of the water turbine. By using this water tank, it is possible to confirm the power generation performance of the actual machine. By consistently handling design, manufacturing, performance verification tests, construction, and on-site adjustments in-house, we achieve low prices.
