Heat exchange apparatus with twisted tubes SHELF

The heat exchange apparatuses with twisted tubes are designed to carry out heat exchange processes between liquids, gases, vapours, vapour-gas mixtures at convective heat exchange, condensation or boiling of working media. According to parameters and design differences, heat exchangers with twisted tubes are divided into several types, depending on the model, equipment capacity and heat exchange area. Working pressure in the tube space, MPa (kgf/cm²): from 0.2 (2.0) to 20.0 (200.0) inclusive; in the intertube space, MPa (kgf/cm²): from 0.02 (0.2) to 1.57 (15.7) inclusive. Operating temperature from minus 165º? to plus 50º?. Heat exchange surface area: 8 to 80 m² inclusive. Power: from 34 to 980 kW. Capacity, m³ (litres): pipe space - from 0,005 (5,0) to 0,05 (50) inclusive; intertube space - from 0,06 (60) to 0,6 (600) inclusive. Service life - not less than 20 years.
