Yazaki Energy Systems, Inc. (YESI) is a global leader in the manufacture of non-CFC based absorption chillers and chiller-heaters. Our gas-fired chiller-heaters can provide cooling or heating, while using much less electricity than a typical electric-powered vapor compression chiller. Our water-fired chillers or chiller-heaters are ideal for waste heat applications, whether driven by a solar, microturbine, cogeneration, fuel cell, or other waste-heat source. A Yazaki absorption chiller-heater, using water as the refrigerant, is today's best choice in air conditioning for protecting the environment and reducing the cost of energy. Capacities of 5 through 200 RT are available to either cool or heat installations such as schools, offices, hospitals, industrial facilities, and hotels. Our founding president, Sadami Yazaki, created our distinctive arrowhead trademark back in 1951 to signify development and progress. The color red symbolizes our passion and spirit of unity. These traits are alive today at Yazaki Energy Systems, Inc. as we strive to offer the best in absorption type chiller-heaters.
