Direct-Fired Vapour Absorption Chiller

Non-Electric Cooling and Heating Solution for Industrial and Commercial Applications

The BROAD Direct-Fired Vapour Absorption Chiller is a premium, thermally-driven HVAC solution engineered for industrial and commercial environments seeking reliable, energy-efficient, and non-electric cooling and heating. This advanced system leverages natural gas or light fuel oil to deliver high-capacity cooling and hot water with minimal electricity demand and ultra-low emissions—making it ideal for large facilities, data centers, manufacturing plants, hospitals, and sites with unstable power supply.

What Is BROAD Direct-Fired Vapour Absorption Chiller?

This chiller utilizes state-of-the-art lithium bromide-water absorption technology for sustainable, high-performance cooling ranging from 233 kW to 11,630 kW (66–3,300 RT), and can provide hot water up to 65°C. It is powered by a dual-fuel burner (natural gas or light oil) and designed for environments where eliminating electric-driven cooling is crucial.
