Bitolea welcomes ‘waste saving’ heat exchanger

16 January 2008

Bitolea, Italian waste management company, has cut disposal and transport costs by reducing waste with an 80 tube Unicus heat exchanger.

The product, supplied by HRS, allowed the company to increase evaporation by 20-25%.

The 35% of waste, previously sent to the cement factory for burning, has fallen and, the company claims, created savings that will pay for the units in six to seven months.

With the Unicus, chemical waste is pumped down the inside of a tube containing a shaft on which scraper blades are placed at regular intervals. The shaft inside the tube is moved backwards and forwards giving a reciprocating longitudinal motion that moves the scraper blades along the tube wall. The result is that the internal tube walls are kept clean at all times so the equipment works in a non-fouling condition at optimum heat transfer efficiency.
