ADVANTAGES

Multi-stage quality assurance

All GRASYS produced systems undergo an obligatory three-stage quality control procedure that helps guarantee their enhanced depen- dability and long operational life under most demanding applica- tions.

Economic benefits

Following the substitution of out-of-date cryogen or adsorp- tion systems, nitrogen savings generally exceed 50%.

Customization

requirement, the output capacity of a plant may be increased at minimum cost. This option appears all the more useful when the project envisages a subsequent increase in enterprise capacity. The cost value of the nitrogen produced with nitrogen plants is 20 to 30 times less than the cost of ready-bottled or liquefied nitrogen. The design and manufacturing of GRASYS nitrogen plants is cus- tomer-oriented and tailor-made for each specific customer objective. This approach in the design of nitrogen systems helps deliver to customer the optimal solution when the equipment specifications precisely match customer individual requirements.

Dependability Technical documentsand permits

The absence of moving compo-nents in gas separation blocks ensures the exceptional dependabi- lity of Company plants. Membranes are highly resistant to vibration and shocks, chemically inert to greases, moisture-insensitive, and capable of operating over a wide tempera- ture range of -40°Ð¡ to +60°Ð¡. With the appropriate maintenance, the membrane block useful life ranges between 130 000 and 180 000 ho- urs (15 to 20 years of continuous operation). The engineering package inclu-des the detailed operations manual and all technical passports and certificates. All systems are provided with the “Permit for application” issued by the Federal environmental, engineering and nuclear control agency (Rostechnadzor).

Module design

The advantage of modularity makes GRASYS plants especially beneficial for Company clients. On

Simplicity and convenience

Membrane nitrogen plants are fully automated and require no personnel for their operation. The start-up and shut-down periods runs for just a few minutes. The output nitrogen purity can be adjusted from 90.0 % to 99.9 % while the system is in-service. 5
