Non-Electric Chillers

BROAD X Absorption chillers

The input heat energy heats LiBr solution to generate vapor, which is then condensed into water by cooling water. When the refrigerant water enters evaporator (in high vacuum condition), its temperature goes down immediately. And it is sprayed over the co

More Information on Non-Electric Chillers

In a typical office building the air-conditioning system makes up to 50% of the total energy consumption. In lieu of electricity, Non-Electric chillers use heat to produce the cooling effect and can help us to largely reduce the electricity consumption. With cooling load demands being in phase with the sun\'s intensity, cooling from intense solar radiation is definitely the route to take in order to achieve the highest saving of energy.

Range of capacity: We propose a wide range of absorption and adsorption chillers, from 5 kW to 12 MW, and adsorption chillers.


We provide a wide range of world-class absorption chillers that significantly reduce ever-rising energy bills, while increasing off-grid cooling efficiency. These chillers are designed for commercial applications and building projects that require chilled water for central air-conditioning systems. Whereas regular compression cooling depends on electricity, which elevates the overall costs and energy consumption and in addition creates CO2 emissions, non-electric chillers can run on any kind of heat such as:

  • Hot water
  • Solar thermal
  • Waste heat from co-generation or biomass
  • Waste heat from district power station or industry
  • Direct heat fired by gas

Yazaki profile

With over 30 years\' experience in developing and manufacturing absorption chillers, YAZAKI is often referred to as \'The Pioneers of Absorption\' and is today the worldwide leader for small to medium sized absorption chillers. With over 50 engineers exclusively dedicated to the research and development of our absorption chillers, the company is constantly implementing it\'s technologies:

  • 1970: developed its first Aroace absorption chiller and set-up the first mass production of small to medium sized absorption chiller,
  • 1974: YAZAKI designed the world’s first solar powered air conditioning system
  • 1980: Started of production of the double effect absorption chiller/heater Aroace CH-DE series (70 & 105 kW)
  • 2007: YAZAKI launches its new Aroace WFC-SC 5 model, featuring 17.5 kW cooling capacity for the European market

With over 100,000 chillers installed worldwide and an established workforce of over 200,000 employees, Yazaki is the world leader from small to medium sized technology: 170 companies over 38 countries are affiliated.
YAZAKI absorption chillers, using water as refrigerant, are protecting the environment and reducing energy costs. They also cover basic cooling loads and ease electrical peak demands.
YAZAKI single-effect and double-effect chillers are offered in a wide range of capacities from 17 kW to 700 kW.

SorTech’s profilenonelec_chillers04

SorTech AG develops, manufactures and distributes adsorption chillers in the small scale performance range. Founded in Germany as a spin-off of Fraunhofer-Institute for Solar Energy Systems (ISE) and UFE Solar GmbH in Freiburg, the company won the IQ innovation price Halle in 2007.

SorTech’s adsorption chillers are available for a performance range from 5 to 60 kW. By interconnecting single modules up to 60 kW, various cooling capacity can be achieved. One of the advantages of those units is the low minimum driving temperatures, starting at 60°C and robust up to 95°C. Moreover, prototypes have been tested successfully at different locations during cooling season 2007.
