Absorption Chillers & Heat Pumps for Cooling & District Heating
Thermax Europe Ltd is the leading supplier of absorption chillers and absorption heat pumps in Europe — proven, energy-efficient, waste-heat-driven technology from district heating to precision industrial and data centre cooling.
The Benchmark for Absorption Technology in Europe
Thermax Europe Ltd is Europe’s leading supplier of absorption chillers and absorption heat pumps. Operating from Milton Keynes, UK, we supply, engineer and commission world-class energy systems across the continent — as the European subsidiary of Thermax Limited, a global leader in energy and environment solutions.
Our systems harness waste heat and low-grade energy to deliver heating and cooling simultaneously — dramatically reducing carbon footprint and operating costs for district energy, industrial, commercial and data centre clients.
- Full lifecycle support — feasibility, design, installation, commissioning and aftercare
- Network of 20+ specialist distributors across the UK and mainland Europe
- Capacity range 500kW to 40MW — scalable for any application
- Temperature profile spanning −5°C to 160°C
Absorption Cooling & Heating Solutions
A complete portfolio of waste-heat-driven absorption technology — engineered for industrial cooling, district heating, data centres and heat recovery across Europe.
Absorption Chillers
Waste-heat-driven chillers using natural refrigerant (water) — single-effect, double-effect, direct-fired, hot-water and exhaust-gas models delivering sustainable cooling with minimal electricity.
- Capacity 175kW to 12,300kW
- Chilled water down to −5°C (sub-zero)
- COP up to 1.5 (double-effect)
Absorption Heat Pumps
Upgrade low-grade waste heat into high-temperature hot water and steam for district heating and industrial processes — including Type I heat pumps, Type II heat transformers and combined heat pump chillers.
- Capacity 500kW to 40MW
- Output temperatures up to 160°C
- COP up to 1.75
Data Centre Cooling & Heat Recovery
Dual absorption solutions for data centres — exhaust-fired chillers cool efficiently using CHP waste heat, while heat pumps recover server waste heat for district heating networks. Reduce PUE and cut energy costs.
- CHP-driven cooling, near-zero cooling electricity
- Server heat recovered into district heating
- Turns data centres into community heat suppliers
Flue Gas Condensation
Absorption heat pumps combined with SEGFlu scrubber technology recover waste heat from boiler flue gases — cutting chimney temperatures to 15-25°C and boosting overall plant efficiency by 10-20%.
- Efficiency gain of +10% to +20%
- Chimney temperature reduced to 15-25°C
- Proven across Denmark and Sweden
Six Innovations That Set Thermax Apart
Proprietary technologies refined over decades — delivering performance unavailable in conventional heating and cooling systems.
Sub-Zero Cooling
Achieve water at 1°C and brine as low as −5°C — unlocking cold storage, food processing and low-temperature industrial applications impossible with conventional systems.
Zero Crystallisation Design
Online concentration measurement and active control ensures the machine never crystallises under adverse conditions, maximising uptime and eliminating costly interventions.
Advanced Series Flow Cycle
Proprietary series flow cycle delivers negligible internal corrosion risk, extending machine lifespan and significantly reducing long-term maintenance expenditure.
Two-Stage Evaporation
Achieves the lowest specific fuel consumption in its class, reducing cooling tower water usage and delivering measurable savings across the system’s lifetime.
High-Efficiency Online Purge
Non-condensable gases are continuously purged during live operation, maintaining optimal vacuum and guaranteeing consistent long-term thermal performance.
Widest Tube Metallurgy
Tube metallurgy fully customised to site water quality — including Titanium and Stainless Steel options for extreme conditions such as seawater cooling circuits.
Recent Installations & Commissioning
Proven performance across Europe’s most demanding district heating, industrial and commercial applications.

Absorption Chillers & Heat Pumps — Explained
Who is the leading absorption chiller and heat pump supplier in Europe?
Thermax Europe Ltd is the leading supplier of absorption chillers and absorption heat pumps in Europe, with over 1,000 installations across the UK and mainland Europe. Based in Milton Keynes, UK, it is the European subsidiary of Thermax Limited and supplies, engineers and commissions absorption cooling and district heating systems from 500kW to 40MW.
What is an absorption chiller and how does it work?
An absorption chiller produces chilled water using waste heat — such as steam, hot water, exhaust gas or fuel — instead of electricity-driven compression. It uses water as a natural refrigerant and a lithium bromide salt solution as absorbent. Thermax absorption chillers range from 175kW to 12,300kW and produce chilled water down to −5°C.
What is an absorption heat pump used for?
An absorption heat pump upgrades low-grade waste heat — from flue gas condensation, waste incineration, biomass plants, CHP plants or industrial processes — into high-temperature hot water for district heating and industrial applications. Thermax absorption heat pumps deliver 500kW to 40MW with output up to 160°C and COP up to 1.75.
Where is Thermax Europe based and which areas does it serve?
Thermax Europe Ltd is based in Milton Keynes, United Kingdom, and serves clients across the UK and mainland Europe through a network of more than 20 specialist distributor partners. Contact the team on +44 1908 378914 or at thermax.europe@thermaxglobal.com.
What industries use Thermax absorption technology?
Thermax absorption chillers and heat pumps serve district heating networks, data centres, chemical and petrochemical plants, pharmaceuticals, food and beverage, waste-to-energy plants, hotels and commercial buildings, manufacturing and healthcare facilities across Europe.
