Steam Heating Vaporizer-water bath type
DSW’s water bath vaporizers handle large capacity ranges for petrochemical and cryogenic plants.
They vaporize liquefied gases like oxygen, nitrogen, argon, ethylene, propylene, and liquid natural gas.
These water bath vaporizers manage load ranges from 500 Nm³/h to 195,000 Nm³/h and process up to three gas streams in one unit.

Design and Operation
Each unit features a round water vessel with an overflow nozzle and a submerged coiled tube bundle. Steam lances heat the water directly, and temperature controllers regulate it precisely.
During stand-by, a miniature steam lance keeps the water at 60°C. Water circulation uses buoyancy and gravity, reaching total capacity in two minutes.
Coiled tubes are welded into a ring pipe that distributes liquid and collects gas, promoting efficient water flow.
This layout minimizes material stress, supports rapid load and temperature changes, and allows easy tube bundle removal for cleaning and inspection, improving maintenance efficiency.
Additionally, the tube bundles can be easily removed for cleaning and inspection, enhancing maintenance efficiency.
A steam heating vaporizer efficiently vaporizes liquefied gases like LNG using indirect steam heating.
Steam circulates around the gas, ensuring precise temperature control essential for industrial applications such as LNG terminals and petrochemical plants.
