Direct-Fired Vapour Absorption Chiller

The BROAD Direct-Fired Vapour Absorption Chiller is a high-efficiency, thermally-driven cooling system that operates without the need for electricity. Powered by natural gas or light fuel oil, the system offers dependable air conditioning and hot water generation for large buildings, industrial plants, district energy systems, and facilities with limited grid access.

Engineered with advanced lithium bromide-water absorption technology, this chiller delivers cooling capacities ranging from 233 kW to 11,630 kW (66–3,300 RT), with hot water output of up to 65 °C. Its dual-fuel burner supports both gas and oil operation, offering flexibility in fuel choice while maintaining low emissions with NOx levels below 10 ppm. The unit's modular design enables it to serve multiple functions, including space cooling, process cooling, domestic hot water supply, and supplementary heating.

BROAD's direct-fired model incorporates corrosion-resistant heat exchangers, automatic non-condensable gas purging, and vacuum maintenance systems to extend service life and maintain stable long-term performance. Crystallization prevention, intelligent control logic, and automated capacity modulation ensure optimal operation under partial load conditions, reducing operational costs and improving energy efficiency.

The system requires minimal electrical input making it especially suitable for regions with high electricity tariffs or frequent power instability. With proven deployments across Asia, Europe, and North America, BROAD Direct-Fired Absorption Chillers are widely used in hospitals, hotels, shopping malls, data centers, and manufacturing facilities seeking reliable, non-electric HVAC solutions with reduced carbon footprint.
