Vapour Absorption Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-RAACLE-11512
Quick Answer: The Vapour Absorption Test Rig is a self-contained absorption refrigerator charged with water, ammonia and hydrogen, in which the fluids circulate by density difference with no compressor or pump.
Last updated: October 2026
Key Features
Pre-charged with three working fluids: water, ammonia and hydrogen.
No compressor or pump; circulation takes place by density difference.
Electrically operated generator that separates ammonia vapour from the water.
Condenser where the ammonia vapour gives up its latent heat to the surroundings and liquefies.
Expansion device and evaporator that take heat from the space being cooled.
Hydrogen present as an inert gas with no phase change.

About This Product
The rig lets students trace the absorption cycle stage by stage. In the electrically operated generator, ammonia vapour is separated from the water; the vapour condenses, falls in pressure and temperature through the expansion device and picks up heat in the evaporator before being absorbed back into water. The strong solution returns to the generator and the cycle repeats.
Frequently Asked Questions
How does the refrigerant circulate without a compressor?
There is no compressor or pump in the system. The fluids move round the circuit by density difference, while an electrically operated generator separates the ammonia vapour from the water solution.
What is the hydrogen for?
Hydrogen is present as an inert gas. Unlike the ammonia, which evaporates and condenses, it does not change phase or take part in the heat transfer processes.
