Teralba Dimpleflo Tubular Heat Exchangers

Teralba Industries has upgraded its range of Dimpleflo Tubular Heat Exchangers for enhanced turbulence within the product tubes. The Dimple profile has been improved to further increase turbulence, resulting in higher efficiency and heat transfer coefficients, especially when heating or cooling viscous or fouling product.

The tube-in-tube design resists blockage, even when processing products such as jams, purees, toffee and pet foods. A further advantage of the profile is that the increased turbulence within the tube wall also self-cleans the heat exchanger, minimising maintenance costs and downtime.

The six o’clock position in the base of each heat exchanger has a clear draining passage, which means the heat exchanger aids the draining of product and heating/cooling media.

The heat exchangers are manufactured from 304 or 316 stainless steel and can be engineered to withstand pressures of up to 25 bar (362 psi) in the product flow path. Where products have high chloride content or other corrosive ingredients, the heat exchanger can be constructed from corrosion-resistant materials such as duplex stainless steels and titanium.

With sizes ranging from 25 to 200 mm configurations, the heat exchangers can be sized to suit heat transfer applications from 200 to 200,000 kg/h.
