Absorption Heat Pumps

BROAD Absorption Heat Pump Solutions

The BROAD Absorption Heat Pump is an advanced thermal energy solution engineered to recover low-grade waste heat and convert it into high-temperature water for efficient heating applications. Using industrial waste heat, steam, hot water, exhaust gas, or natural gas as its driving source, this system elevates energy efficiency far beyond traditional boiler-based systems, delivering 2 to 3 times the heating output per unit of input energy.

Thermal-Driven Heat Transfer Technology

Unlike conventional electric heat pumps, BROAD's absorption technology operates without CFCs or HFCs, instead using environmentally benign water as the refrigerant, ensuring clean energy use with a low carbon footprint.

Engineering Highlights & Advantages

⚡

Thermal Lift Efficiency

Achieves Heating Coefficients of Performance (COP) between 2.0–3.0—delivering two to three times more heat per unit thermal input compared to conventional boilers, and enabling payback through energy savings.

🌱

Eco-Friendly Refrigerant

Utilizes water and lithium bromide, a non-CFC, non-HFC refrigerant pair, ensuring compliance with global environmental regulations.

🔧

Robust Construction

Incorporates corrosion-resistant heat exchangers and vacuum stability safeguards, along with automatic purge, crystallisation prevention systems, and intelligent control modules for long-term, trouble-free operation.

🔄

Versatile Thermal Inputs

Accepts low-temperature waste heat sources (surface or cooling water at 59–122 °F) and combines with higher-grade heat (steam, hot water, exhaust gas) for flexible deployment across industrial and municipal systems.

🎯

Uninterrupted Heating

Offers stable heat delivery even under ambient or supply fluctuations, without requiring back‑up electric heating—unlike traditional electric heat pump systems.

Global Deployment & Success Stories

BROAD Absorption Heat Pumps are deployed globally across power plants, industrial parks, and municipal heating stations in countries including South Korea, Denmark, Austria, China, and Thailand.

These systems excel in challenging industrial environments recovering waste heat from dyeing mills, breweries, power plant cooling loops, and boiler exhausts to produce high-temperature water between 140–190 ºF for immediate use.

Thailand Paper Mill

Recovered 3.3 MW of cooling water heat

South Korean Power Station

Converted 48 MW of waste heat for district heating

Result: Up to 41% savings in heating energy and rapid ROI

Proven Applications & Performance

🏭

Thermal Power Plant Systems

Achieves 15–20% energy-saving by upgrading waste cooling water (59–86 °F) to preheat boiler feedwater using steam drive

Example: Thai paper factory deploying a 3.3 MW system, and South Korea's 48 MW plant for district heating

🏗️

Industrial Process Heating

Delivers up to 41% energy savings by recycling low-temperature waste streams (86–122 °F) across various industries

Example: Korean eco-park, Austrian district heating system, Chinese brewery - dyeing, breweries, steel finishing, oil field operations

♻️

Exhaust-Driven Heat Recovery

Delivers 8–15% energy efficiency gains by capturing boiler, turbine, or chiller exhaust (140–356 °F) to produce heating water at ~185 °F

Example: Biomass plants (Denmark), event centers (Beijing National Games Centre), and energy plants in South Korea

Unmatched Performance & Reliability

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.
