Overview
An absorption heat pump (AHP) is a thermally-driven energy recovery system. Unlike an absorption chiller that produces cooling, an AHP captures low-grade waste heat (e.g., 30–80°C cooling water) that is normally discarded into the environment, and uses a high-grade driving heat source (like steam or natural gas) to 'pump' or upgrade that waste heat to a much higher, useful temperature (e.g., 90–130°C) for process heating or district heating networks.
In many heavy industries and thermal power plants, massive amounts of low-grade heat (30–80°C) are continuously dissipated into the atmosphere through cooling towers or dumped into rivers, while simultaneously, fossil fuels are burned to generate high-grade heat for processes or district heating. The BROAD Absorption Heat Pump is designed to break this inefficient cycle.
By utilising the lithium bromide absorption cycle, our AHPs recover this vast, untapped low-grade thermal energy and upgrade it to a usable temperature. This process essentially multiplies the efficiency of the driving heat source, delivering up to 1.7 times more heating energy than the fuel consumed. It is a critical technology for deep industrial decarbonisation, turning thermal waste streams into high-value process heating.

Engineering
Recovers vast quantities of low-grade heat (30–80°C) that conventional heat exchangers cannot utilize.
Available in Type I (amplifies heating capacity using high-grade drive heat) and Type II (amplifies temperature using medium-grade drive heat without additional fuel).
Can be driven by steam, natural gas, or exhaust gas, depending on the facility's existing energy infrastructure.
By recovering heat rather than rejecting it through cooling towers, AHPs drastically reduce evaporative cooling water consumption.
Engineered for 24/7 continuous operation in harsh environments, featuring specialized corrosion-resistant materials.
Business case
Produces significantly more heating energy than the driving fuel consumed, slashing primary boiler fuel costs.
Directly displaces fossil fuel combustion for heating, delivering massive reductions in industrial CO₂ emissions.
Reduces the thermal load on cooling towers, eliminating visible vapor plumes and thermal pollution in local waterways.
Where it’s used
For thermal power plants in India, energy efficiency dictates profitability. By deploying a BROAD Absorption Heat Pump, power plants can recover the massive latent heat lost in condenser cooling water. This recovered heat is then used to preheat the boiler feedwater or supply a district heating network. The result is a direct 15% to 20% reduction in coal or fuel consumption while maintaining the same electrical output, fundamentally improving the plant's heat rate and extending the operational lifespan of the boilers.
In the broader industrial sector - including textiles, chemicals, paper mills, and food processing - facilities generate massive volumes of low-temperature effluent and exhaust gases. A BROAD AHP captures this waste heat to produce process heating water up to 90°C (194°F). This completely offsets or eliminates the need for fossil-fuel-fired boilers, slashing fuel costs and rapidly accelerating the facility's return on investment. Some industrial applications have documented up to 41% total energy savings following the integration of our heat pump technology.
As India accelerates its commitment to reducing industrial emissions, the shift away from coal-fired and oil-fired boilers is imperative. The BROAD Absorption Heat Pump offers a clean, zero-emission alternative that aligns with the strictest environmental standards. Because the system utilizes a closed-loop lithium bromide-water absorption cycle, it uses water as the natural refrigerant, entirely eliminating ozone-depleting CFCs and HFCs.
Furthermore, BROAD's heat pumps are engineered for unparalleled longevity and reliability. Without the heavy moving parts of mechanical compressors, the system operates with minimal vibration and noise. Equipped with robust corrosion-resistant heat exchangers, intelligent anti-crystallization controls, and continuous automatic vacuum purging, a BROAD AHP guarantees stable, uninterrupted heat delivery even under fluctuating ambient conditions.
With its unmatched ability to stabilize heat output even in fluctuating load conditions, BROAD Absorption Heat Pumps redefine sustainable heating by merging environmental responsibility with robust engineering.
