Backed by decades of expertise as a specialized manufacturer of refrigeration plants and systems, Hasegawa Iron Works’ compressors deliver reliable performance, high service satisfaction, and reduced total cost of ownership. Proven in demanding applications such as marine refrigeration for fishing vessels, they are trusted across multiple industries and hold a strong track record with a leading market share.
Wide Range of Series Configurations
Centered on our space-saving flange motor series, we provide optimal selection and tailored recommendations to meet specific applications and operating requirements.
High Quality - High Performance Compressors with Advanced Technical Precision
Hasegawa Iron Works compressors are series-designed to ensure high-efficiency operation and adaptability across a wide temperature range. Engineered for peak performance, each unit utilizes carefully selected materials and rigorous quality control, delivering exceptional durability and superior performance.
The standard oil pump ensures stable oil pressure with minimal fluctuation, even in ultra-low pressure conditions. The flange motor type combines Hasegawa’s advanced engineering expertise with a high-performance squirrel-cage motor, achieving exceptional durability and high-efficiency operation optimized to the characteristics of the refrigeration system.
Ultra-light pistons and rods, combined with a high-performance valve design, deliver maximum efficiency. Advanced cooling keeps discharge gas temperature low, while the oil-return prevention system minimizes oil consumption.
Flange-motor models feature excellent air cooling for consistent high-efficiency operation. Standard hydraulic capacity control and inverter compatibility reduce starting torque and optimize performance under varying loads.
Significant Reduction in Maintenance Costs
Simplified Design for Easy Maintenance and Long-Term Reliability
Designed with simplicity in mind, the compressor’s structure allows for quick and reliable maintenance in a short time. The use of highly durable components significantly reduces maintenance costs.
In the flange motor type, the motor is directly mounted on the compressor shaft, eliminating the need for coupling alignment adjustments. Furthermore, the standardized design of key wear parts and Hasegawa Iron Works’ comprehensive parts supply system ensure long-term, worry-free operation.
Space-Saving Design
The flange-motor type eliminates couplings and other components, achieving significant space savings. (The term “flange-motor type” refers to an integrated motor-compressor design.)
