DESUPERHEATER – SERIES 800

DESUPERHEATER – SERIES 800

BUILT IN RELIABILITY PVCT-800 Desuperheater is a device that reduces the temperature of superheated steam so that it can be used effectively for heating or for other industrial use. This temperature reduction or attemperation is performed by desuperheater, which is essentially a device that injects a predetermined amount of water into a steam flow stream. The desuperheaters are highly effective in controlling steam temperature close to saturation point over a broad set of steam conditions The desuperheater provide effective heat transfer between steam and water. A highly effective desuperheater design and application ensures that costly problems are avoided including extended startup and shutdown times, reduced process efficiency and general wear of downstream piping and equipment. Pneucon incorporate latest technology in the spray nozzle design. The high quality surface finish minimises frictional losses, thereby ensuring that the total pressure difference between water and steam is available for atomisation of water.
