There's Only One Earth. So there's a Responsibility.
To protect the earth and to protect the environment is the common issue of the mankind.
The traditional electric chiller which takes Freon as its cooling medium has caused great harm to the ozone layer of the atmosphere, which can never be tolerated by the mankind. The far-sighted personnel in the field of refrigeration and air conditioning cannot turn a blind eyes to this phenomenon.
The lithium bromide absorption chiller adopts solution of lithium bromide as its working medium, which is non-volatilization, non-deterioration, and pollution-free.
Direct-fired lithium bromide absorption chiller/heater, with its high energy efficiency and outstanding environment-friendly performances, can save energy and greatly reduce the generation of greenhouse gases such as carbon dioxide, etc., having positive influences in anti-air pollution and improvement of energy utilization. Because of the high energy efficiency and outstanding environmental benefits, Chillers direct-fired units are enjoying more and more popularity among users.

Pioneering technology had been used to ensure the advanced features of chiller
1. Pioneering a chiller with two pumps and without spray nozzles solves the degradation of cooling capacity forever. S.G. constructed the first in China absorption chiller with two pumps and without spray nozzles, which eliminates the rapid degradation of cooling capacity. In order to attain the aim, a chiller with two pumps and without nozzles is manufactured with the know how, such as Left-Middle-Right arrangement of absorber-evaporator-absorber, absorber with dripping plates instead of spray nozzles, which did not needs solution spray pump. With this technology, the chiller can be operated for more than 20 years instead of 3-5 years.
2. Solution heat exchanger with new construction and flow pattern improves chiller energy efficiency and reduces fuel consumption. Heat exchangers are designed with new tubes and their supports, furthermore with new flow pattern, that leads to improve heat transfer and reduce flow pressure drop. These measures improved chiller energy efficiency and reduced fuel consumption.
3. Distribution of refrigerant by dripping plates improves chiller energy efficiency and reduces fuel consumption. The special form of distribution of refrigerant by dripping plates improves the wetting of tubes by Distribution of Refrigerant by refrigerant, fully uses the heat transfer area, reduces the refrigerant film thickness, increases the Dripping Plates heat transfer effects, and results in improvement of chiller energy efficiency and reduction of fuel consumption.
4. New tubes and their arrangement in evaporator improves chiller energy efficiency and reduces fuel consumption. Application of new tubes and their arrangement in evaporator makes more even distribution of heat transfer effect, and thus to improve chiller energy efficiency and reduce fuel consumption.
5. Special construction of high pressure generator improves chiller reliability and energy efficiency, and reduces fuel consumption. High pressure generator with solution inside tubes and wet back of combustion chamber improves chiller operation safety, and reduces fuel consumption.
6. Heating by evaporator improves heating efficiency and safety of operation Heating by evaporator improves heating efficiency to 92.5% and improve the operation life. 7. Evaporator tubes are protected from freezing to improve the chiller reliability. Evaporator tubes are protected from freezing with such measure, as chiller can stop cooling very quickly. It is realized by interrupting the operation of refrigerant pump, if failure of power or chilled water occurs, because refrigerant water from condenser is collected in the sump of evaporator, and pumped to the dripping plate for distributing over tubes.
8. Serial flow of solution to improve chillier reliability. Serial flow of solution in chiller makes solution far from crystallization line to improve chillier reliability and simplify the control of chiller.
9. Pioneering non-condensable gas purging during heating improves the chiller reliability. The direct fired absorption chiller can be purged by pioneering technology to improve the chiller reliability and improves chiller operation life.


All these patented technologies and other pioneering know how are implemented aiming at making the chiller operation more efficient, easy and reliable.
