Azadi Sport Complex

One of the oldest HydroFlow installations in Iran is the Azadi central mechanical room. It is equipped with 4 hot water boilers with total capacity of 96 billion BTUs per hour form Cleaver Brooks Company. 2 boilers have been replaced due to scale build up and tube failure. The central mechanical room supply hot water from 130 to 140 degrees Celsius to 100000 seat football stadium, 12000 seat volleyball saloon, central office building, pool complex, Olympic dormitory complex and other buildings. The primary energy loop has an approximate length of 5400 m with size of 14 inches. In 2007, a 14-inch custom Hydroflow descaler was installed on the hot water return line to the boilers which came from secondary mechanical rooms. The HydroFlow descaler is able to remove the existing calcium and magnesium carbonate deposits over time. The scales became soft powder so that they could be easily cleaned and washed away from metal surfaces which are visible in the photos below.
