Atlas Copco expands line of nitrogen generators



The NGMs generator units consist of one or multiple membrane modules combined to achieve the nominal inlet flow, ensuring the maximum output of compressed nitrogen for the minimum input of compressed air in a wide range of operating conditions.Get more news about nitrogen compressor exporters,you can vist our website!

Dry compressed inlet air is separated into component gases by passing it through semi-permeable membranes consisting of bundles of extremely small individual hollow fibres packed into a limited space. This provides a very large membrane surface area to produce a relatively high-volume product stream. As water vapour also permeates through the membrane, the nitrogen gas stream is very dry, with dewpoints as low as -58º F.

In order to allow continuous operation, the nitrogen generators are equipped with a two-stage premium pre-filtration system to ensure an inlet air quality of [1:-:1] according to ISO 8573-1:2010. This eliminates the risk of the membrane being damaged by a low-quality compressed air supply, a poor start-up or an unexpected shut-down.
The two new 16 Bar aluminum twin filter models, the UD 850T and UD 1100T, can be used in numerous applications including challenging marine environments. Building on the existing aluminum filter line up to 2000 Nm³/h, they offer high flow filtration solutions of 3000 Nm³/h and 4000 Nm³/h respectively; at reference conditions of 7 Bar.

The new filters are ISO12500-1 verified. This includes all patented UD grade oil coalescing filters, which replace two traditional 1 micron and 0.1 micron coalescing filters with one single filter offering the same filtration rate at 40% less pressure drop.

The existing QDT carbon tower range has been expanded with five new 16 Bar fabricated vessels. The combination of the QDT activated carbon towers and the new twin filter UD+ type pre-filter and PDp type post filter offers high levels of control to prevent the risk of oil and dust contamination.
