This is easily achieved using good quality down stream gas pressure regulating valves. It is recommended to use a well designed valve, and never think an ordinary air pressure regulator will, do a reliable job. TGs which have within loop Hydrogen Dryer are the lucky ones. They at least have the technical facility to keep Hydrogen Dew point in check. Many Power Utilities are using commercially available Hydrogen gas supplied in Gas cylinders or Bullets. Commercial Hydrogen is typically procured from the off-gas stream of process industries such as Chlor-Alkali plants. This Commercial grade Hydrogen of 99.8% purity (or worse), and questionable Dew point is wet (saturated). Ensuing wet gas affects the Generator winding life. One needs superior quality gas to keep the Dew point low. Just like, you need clean water, to wash dirty clothes. Either this be done by online Hydrogen dryer or use Hydrogen gas of superior Dew point (-) 60°C or better, and successfully use the ‘displacement method’ to control purge atmosphere Dew point.

Mellcon Engineers offer quality Hydrogen Gas Dryers to ensure low humidity levels continuously inside the Generators in Power Plants. Manufactured from the premium quality raw materials our Hydrogen Gas Dryers are highly durable and reliable. Hydrogen Gas Dryers provided by us are highly efficient, thus needs less energy and provides excellent performance. Hydrogen Gas Dryer is easy to use and install. Hydrogen Gas Dryer (Refrigerated Type)(Moisture Upto -20 Deg.C ADP) Capacity 40Nm3/Hr to 60 Nm3/Hr Op. Pressure 3.5 kg/cm2g to 7.0 Kg/cm2g Operation The system comprises two heat exchangers, the hydrogen shell and tube type called pre-cooler in which temperature of hydrogen reduces around 25-30 (Deg C. ). The cooled hydrogen now enters the second heat exchanger named evaporator, further cooling upto 0-3 (Deg.C) is accomplished in this hence the set dew point is adjustable. The cooling coil inside the evaporator have propelled through a refrigeration system due to low temperature in the evaporator. The moisture in the hydrogen condences and converts in water form. The water is collected in a well protected condensate collector and can be drained out when desired leaving the evaporator. Hydrogen again travels to pre-cooler where it has dual function of cooling and outgoing leaving dry hydrogen again rises to a safe temperature Hydrogen of around 25-40 (Deg C.)

We are offering a wide range of Breathing Air Systems. ( Medium & large flow) Adsorption dryers of the DPS 1-8 BI and BM series are designed for drying and purification of compressed air for breathing air applications.BI stands for Breathing air Industrial, thus for Industrial use acc EN12021 and BM stands for Breathing air Medical, thus medical breathing air acc. Pharmacopeia European, as it is demanded for hospitals. With both systems apart from the drying process to a pressure dew point of -40° C also the components CO, CO2, hydrocarbons, nitrogen Oxides and SO2 are reduced so far, to residual valves underneath the limit values acc EN12021 respectively Pharmacopeia European.
