One PHE model cools an entire man-made island

The Pearl Qatar, located close to the centre of Qatar’s capital Doha, is a man-made island spanning close to 4 million square meters. Its integrated district cooling (IDCP) plant - supplying all residential and commercial venues on the island - is the largest in the world of its kind. Thanks to a longstanding relationship with the leading district cooling supplier Qatar Cool, Alfa Laval was selected to supply the plate heat exchangers for this milestone project.

A matter of trust

According to Mr Issa Quandeel, Project Manager at Qatar Cool, trust was a major decision parameter when Alfa Laval was selected:

“Alfa Laval offers high quality products at competitive prices, competent management and strong after sales support. We plan for a long-term relationship with Alfa Laval”.

Reliability a must

The project was carried out in 2008 and 2009, and equipment performance has been immaculate ever since. Since undisturbed operation is an imperative, efficient after sales service is crucial. The maintenance work of one gasketed PHE can be undertaken while the others are kept operating. To ensure trouble-free operation, we have also developed an efficient model for swift spare part supply.

One model - multiple cooling loads

The heat exchanger selected was T20B from Alfa Laval. Handling the whole range of cooling loads with one model of heat exchanger means facilitated spare part supply and uniform procedures for operation and maintenance. Another basic requirement was a close temperature approach. With the T20B, a temperature approach condition of 1.1°C is met.

Substantial energy savings

Efficient control functions allow residents to use the cooling energy according to the actual need. This - along with the efficiency of the plate heat exchangers - means substantial energy savings in comparison with traditional systems.
