Manufacturer · Official distributor
Thermax absorption solutions produce chilled water, hot water and process heat from thermal energy sources such as hot water, steam, flue gas or waste heat. Thanks to lithium bromide absorption technology (LiBr H2O), they offer a high-efficiency alternative for air conditioning, industrial processes, cogeneration, district heating and decarbonisation.
With one of the most complete ranges on the market, Thermax develops absorption chillers and absorption heat pumps that turn low-value thermal energy into useful cooling or heating, reducing electricity consumption, optimising energy use and lowering CO2 emissions.

Advantages
It recovers thermal energy that would normally be released to the atmosphere and turns it into cooling or heating, increasing the overall performance of the installation and reducing energy waste.
Using thermal energy as the driving force significantly reduces electricity consumption compared with conventional compression technologies, especially in installations with usable heat sources.
It helps reduce CO2 emissions by using waste heat, lowering electricity consumption and reducing dependence on fossil fuels.
The units use water as the refrigerant and lithium bromide (LiBr) as the absorbent, avoiding fluorinated refrigerants with a high global warming potential.
Thermax solutions can run on hot water, steam, direct firing, exhaust gas or waste heat, adapting to the energy characteristics of each installation.
The same technology can produce cooling with absorption chillers or recover heat to generate high-efficiency hot water with absorption heat pumps, optimising the use of the energy available.
One of the most complete ranges on the market, with solutions from 175 kW to projects of more than 40 MW, suited both to commercial buildings and to the most demanding industrial applications.
Units designed for continuous operation, with advanced control systems, high mechanical robustness and specific solutions to minimise the risk of crystallisation and simplify maintenance.
The breadth of technologies available makes it possible to select the most suitable solution according to the energy source, operating temperatures and efficiency targets of each installation.
