Vapour Absorpotion Chillers

100 – 1000 TR Cooling capacity

5ºC chilled water Delta T 30ºC

High COP 1.8

Vapour Absorpotion Chillers

Thermax is the first absorption chiller manufacturer in the world to commercialise the ultimate in absorption technology – the Triple Effect Absorption Chiller. This is a major breakthrough in the field of refrigeration and air-conditioning. Triple effect absorption chillers have a Coefficient of Performance (COP) of 1.8, which is nearly 30% higher than the double effect absorption chillers. This helps the user to reduce the energy requirement for cooling significantly.

Thermax triple effect absorption chillers are designed based on its proven advanced series flow technology. This ensures that the highest concentration and highest temperature of Lithium Bromide solution doesn't occur simultaneously. Due to this the rate of corrosion is negligible compared to the para flow or reverse flow technologies. Coupled with an accurate online concentration measurement, the Thermax Triple effect absorption chillers are extremely user friendly and significantly reduces user intervention and down time.

The variable frequency drives on solution pumps helps to improve the COP during part loads and also offers a stable operation. It also increases the life of the solution pump. Ferritic stainless steel tubes in generators of the triple effect machine have thermal expansion coefficient similar to carbon steel and thus helps to avoid the stress corrosion cracking. The plate type solution heat exchangers increase the COP by offering maximum internal heat recovery. The stainless steel plates of these solution heat exchangers ensure long life and reliability.

The operation of the absorption chiller is controlled by stand-alone PLC based control panel. The touch screen HMI provided on the control panel through which the operator can set the necessary set points and can see all the operating parameters, status, alarms, trip logs. The chiller is also equipped with necessary level controls, temperature sensors, flow safety devices etc. to control and safeguard the chiller. For viewing the operating parameters of the chiller from a remote location, MODBUS RTU or Ethernet connectivity is available.

Thermax manufactures these Triple Effect Chillers in India and supplies them to more than 85 countries across the globe
