TRIPLE EFFECT CHILLER

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 manufactures Triple Effect Chillers in India and supplies them to more than 90+ countries across the globe.

STEAM FIRED CHILLERS

Thermax offers a range of steam driven Vapour Absorption Machines driven by saturated steam pressure
at 0.1 kg/cm2 to 26 kg/cm2. Steam driven VAMs are categorised as Single effect, Double effect and Triple
effect depending on the heat source temperature. The source of heat for steam driven VAMs can be:

  • Steam from boiler
  • Steam from processes
  • Steam from cogeneration plants
  • Steam from turbines

Many industries in India and across the world like Food & Beverages, Paper & Pulp, Pharma, Steel, Dairy,
Refinery & Petrochemical, Fertilizers, Textiles, commercial and many more have benefitted from
Thermax’s steam-driven VAMs

SINGLE EFFECT STEAM FIRED CHILLER (SS SERIES)

Single effect steam driven machine is one of the oldest and most established absorption machine, driven by low grade energy and consuming minimum power. In single effect technology, the gain in concentration of the absorbent is achieved using only one generator.

Heat source
  • Steam from turbine extraction
  • Flash Steam
  • Low pressure vapours from process
  • Vapour from Continuous polymerization column
  • Vapour from potato fryers, etc
Operating Range
  • Capacity: From 100 to 2180USRT (350 – 7650kW)
  • Steam pressure: From 0 to 3.5 bar.g( 0 to 50 psig)
  • Chilled water temperature: Up to 1ºC (34ºF) and -2ºC (28.5ºF) with brine

DOUBLE EFFECT STEAM FIRED CHILLER (2B SERIES)

Double effect steam driven absorption machines are one of the most efficient cooling solutions for industrial applications. In the double effect machines, the gain in concentration is achieved in two steps. The primary generator (referred as High Temperature Generator or HTG) produces vapour, whose latent heat is transferred to lithium bromide in secondary generator (referred as Low Temperature Generator or LTG).

Thermax double 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.

Operating Range
  • Capacities: From 50 to 2500 USRT (175– 8800 kW)
  • Heat source: Steam
  • Steam pressure: From 3.0 to 10.0 bar.g (43 to 140 psig)
  • Chilled water temperature: Up to 1ºC (34ºF) and -2ºC (28.5ºF) with brine
  • COP: 1.38 – 1.43
