Dubai, UAE: India-headquartered Bry-Air, in collaboration with US-based Power Partners Inc (PPI), conducted a technical workshop on adsorption chillers on March 6 at Le Meridien, Garhoud, Dubai.

At the workshop, Ashok Kumar Prusty, Executive Vice President at Bry-Air, announced the signing of a licence agreement between the two entities for Bry-Air, to manufacture and sell PPI’s ECO-MAX brand adsorption chillers in the UAE.

The agreement allows Bry-Air to expand its product portfolio to include closed-loop adsorption products. Also, under the agreement, PPI will share its knowledge of adsorption chiller design, manufacturing, applications and marketing with Bry-Air, and assist with product commercialisation.

Speaking about their adsorption chiller technology, Wes Livingston, North America Business Leader at PPI, said that their adsorption chillers use energy from waste heat, with very low electricity consumption, to provide chilled water for process cooling and air conditioning. This, he said, was done with water as refrigerant and silica gel as desiccant.

Elaborating on the advantages of adsorption chillers, he said, “The payback period for an adsorption chiller is 3.64 years in comparison to a water-cooled chiller, and 2.41 years against air-cooled chiller.”

Livingston carried out a lifecycle cost (LCC) analysis for both adsorption and absorption chillers, and concluded that the operational cost for adsorption chillers is approximately USD 150,000, as opposed to an absorption chiller, which is USD 300,000.
