What Yazaki Energy Systems does

Yazaki Energy Systems, Inc. is a Plano, Texas-headquartered manufacturer of non-CFC absorption chiller-heaters serving commercial, industrial, institutional, and municipal customers across North America. The company operates with 1-10 employees out of 542 Haggard Street, Suite 502, and was founded by Sadami Yazaki in 1951 (the current US corporate entity is dated 2012 in firmographic records). Its product portfolio spans capacities from 5 to 200 tons of refrigeration (RT) and includes two technology families: gas-fired double-effect chiller-heaters (CH-K Series at 30-100 RT and CH-MG Series at 150-200 RT) and water-fired single-effect chillers and chiller-heaters (WFC series from 5 RT up to the WFC-M100/WFC-MB100 introduced in 2024 at 100 RT). All products use water as the refrigerant and lithium bromide solution as the absorbent under vacuum, with no electric compression required for the cooling cycle.

The underlying technology is a lithium bromide/water absorption cycle, distinguished by a proprietary solution and inhibitor blend that eliminates field chemical balancing, factory hermetic sealing validated by helium mass spectrometry to a 5×10⁻¹⁰ atm·cc/sec leakage rate, a single rotating-part solution pump with gravity drain-back to prevent crystallization during power loss, and UL50E Type 3R weatherproof cabinets that permit outdoor installation without a dedicated equipment room. The CH-MG series achieves a claimed cooling COP of 1.2 and part-load IPLV above 1.3, with stated fuel savings up to 17% versus competing double-effect units. Heat input can be supplied by natural gas, biomass, waste heat, solar thermal, microturbines, or fuel cells, enabling operation as a non-electric, fuel-flexible, carbon-neutral cooling system when paired with renewable heat.

Yazaki monetizes primarily through one-time equipment sales of factory-charged, run-tested units, with pricing held confidential and quoted on a per-project basis. The go-to-market is enterprise field sales supplemented by trade-show presence (including AHRE Expo Mexico, Booth #3526), a network of Yazaki-authorized service providers across North America for installation and maintenance, and case-study-driven content marketing featuring placements in trade publications such as Municipal World. Customer segments include schools, offices, hospitals, hotels, industrial facilities, food processors, municipal governments, and cultural venues, with more than 100,000 units claimed to be operating worldwide under the broader Yazaki brand. The company operates in a global absorption chiller market sized at $1.48 billion in 2021 and projected to reach $2.267 billion by 2031 at a 4.2% CAGR per Allied Market Research, with Asia-Pacific as the largest regional segment.

Core offering

Yazaki Energy Systems designs and manufactures absorption chiller-heaters that provide cooling and heating without using electric compressors, using a lithium bromide-water absorption cycle under vacuum. The product range spans 5 to 200 tons of refrigeration across gas-fired double-effect (CH-K and CH-MG series) and water-fired single-effect (WFC series) units, sold to commercial, industrial, institutional, and government customers for HVAC and process cooling applications.

Product overview

Yazaki Energy Systems offers a comprehensive portfolio of absorption chiller products for non-electric, thermal-based cooling and heating solutions. The product lineup consists of two main categories: (1) Gas Fired Double-Effect Chiller-Heaters comprising the CH-K Series (30-100 RT models: CH-K30 through CH-K100) and CH-MG Series (150-200 RT models: CH-MG150 and CH-MG200), which directly burn natural gas to energize the absorption cycle; and (2) Water Fired Single-Effect Chillers and Chiller-Heaters spanning the WFC Series with capacities from 5 RT (WFC-SC5) up to 100 RT (WFC-M100 and WFC-MB100). All products utilize lithium bromide and water as the working fluid under vacuum, enabling carbon neutral operations when powered by biomass or waste heat recovery from cogeneration, solar, or industrial processes. The WFC-SH variants provide dual heating and cooling capabilities through a two-pipe hydronic system. With over 100,000 units operating worldwide, the company specializes in non-CFC based space cooling solutions for schools, offices, hospitals, industrial facilities, hotels, and emergency response centers.
