A 4 year field test of the Vulcan electronic descaler was conducted at a Mall’s cooling towers in Indonesia. During the 4 years no system maintenance was required and the system was not treated with chemicals. Mall administration and maintenance report the prevention of rust in their iron pipes has been an added benefit.
Every month the heat exchanger efficiencies dropped dramatically because of an increase in pressure between inlet and outlet of the heat exchanger. Vulcan S250 models were installed and after 5 months there have not been any mineral scale pressure issues in the cooling towers or heat exchangers.
The Lurdy Shopping Mall and Office Centre is a 120,000 square-yard facility comprising of offices, shops and warehouses spaces for rent. Before installing the Vulcan descalers there was no water maintenance system in place and the mall owners had to change the whole cooling panels every 4 years.
