Construction Achievements HASEGAWA Total Engineering — Driving the Future of Refrigeration Technology

With over a century of accumulated expertise and proprietary know-how, Hasegawa Iron Works provides integrated solutions that cover design, construction, and remote management—as a total engineering company for refrigeration and thermal systems.
Through the use of natural refrigerants, energy-saving design, and real-time management, we deliver environmentally responsible plants that achieve both high reliability and efficiency, expanding our reach across the world.
As a company you can entrust with everything related to refrigeration, HASEGAWA continues to respond to the diverse needs of our customers with technology and trust built over generations.

Environmentally Conscious & Energy-Saving Design

• Through system-wide efficiency engineering, we achieve both energy savings and high-quality storage environments throughout the entire refrigerated warehouse.
• By adopting natural refrigerants such as NH₃/CO₂ (NiCRES), overall power consumption is reduced by approximately 40–50% compared to conventional fluorocarbon systems.

High-Performance & High-Reliability Equipment Design

• Our reciprocating refrigeration units deliver a high COP (Coefficient of Performance), combining efficient operation with low maintenance through a lightweight design and an oil carryover prevention mechanism.
• The natural convection coolers operate without fans, reducing power load by 15–20%, while minimizing product drying to help maintain superior storage quality.

Remote Management & Reliable After-Support

• We offer a remote monitoring system that enables predictive maintenance and early issue detection.
• Customer data is centrally managed in a dedicated database, allowing for real-time service response, faster maintenance and repair, and flexible adaptation to future improvement plans.
