DELTA NATURAL GAS FILTERS
Delta Natural Gas Filters are high efficiency filters for filtering solids and liquids from Natural Gas stream. Sizes from 1/2" NB to 16" NB. Serve pressures till 300 Bar. Exported to over 25 countries. Delta Fuel Gas Filters are offered for Dry Gas Filtration as well as Coalescing Gas Filtration. Low 0.07 Bar Pressure Drop and long life, ASME Coded Natural Gas Filter Housings. Compressed Natural Gas (CNG) Filters and Duplex Fuel Gas Filters are also manufactured by Delta Filters. Natural Gas is a convenient fuel source in terms of transmission and combustion. However it gets laden with impurities like oil, dust, rust and condensates during various stages of drilling, compression and transmission. For effective combustion and protection of metering instrumentation it is imperative to install a high efficiency Natural Gas Filter in the Gas Line. Delta Filters is involved in Design, Manufacture & Supply of a wide range of Natural Gas Filters for various applications including City Gas Distribution, metering skids, MRS, DRS & Servo Gas (Instrumentation). Delta Filters has developed efficient designs to serve various Natural Gas Filtration requirements. Our filters used pleated filter elements which allow high flow rate within compact filter housings. Filter Vessels are designed as per ASME Sec VIII Div 1 Code. Welding is carried out by Qualified Welders as per SGS approved WPS / PQR following ASME Sec IX. NDT Procedures are followed as per ASME Sec V.

DELTA NATURAL GAS FILTER ELEMENTS
DELTA Filter Elements / Cartridges : We manufacture and supply highly reliable Natural Gas Filter Cartridges. Pleated borosilicate glassfibre is employed as the filter media which increases filtration area 4x times compared to competitors. End result for the customer is lower pressure drop, long life between replacement and lower maintenance cost.
Glass Fibre Media Structure Coalescing Fuel Gas Filter Elements
Glass Fibre media in pleated construction offer unparalleled advantages for Natural Gas Filtration. The fine micro glassfibres serve the dual purpose of particulate retention and executing the process of coalescence. The media is rated at 0.3 mircon and is sandwiched between felted polyester media. Our coalescing filter elements remove condensates, water & liquid hydrocarbons from the Gas stream. This is accomplished by high surface charge on the glass fibre media, which cause the liquid droplets to adhere to the media. Coupled with this feature the glass fibre media presents proper contact angles within the dense fibre matrix which allows the droplets to combine with other droplets and grow in size. This is the basic principle of coalescence which results in the formation of bulk liquid which then encounters the outer drainage layer of the filter cartridge. This layer is open cell reticulated foam sock based and ensures that the liquid is pulled down into the sump of the filter vessel. DELTA Natural Gas Filters offers the best protection for the end user's equipment against particulates and liquid droplets.
DELTA COMPRESSED NATURAL GAS (CNG) FILTERS
SS304 Compressed Natural Gas Filters, 1" NPT THREADED, 375 BAR TEST PRESSURE
Compressed Natural Gas Filters: Compressed Natural Gas (CNG) is a high pressure gas that is an alternative transportation fuel. CNG is environment friendly in terms of reduction in emission during combustion. Compressed Natural Gas or CNG gets contaminated during its journey through the pipeline to the dispenser. There are various contaminants that should be filtered: solid particles, moisture and lubricating oil carried over from CNG Compressors. Removal of these contaminants is essential to protect the NGV vehicle Engines. DELTA CNG Filters are designed to operate at the high pressure applications of CNG Fueling at 275 Bar (4000 psig). Latest ASME codes are followed in the design of DELTA CNG Filter housings. Borosilicate Glass Fibre based filter elements are used for filtration which offer the lowest pressure drop and long life. These filters remove dirt, condensates, oil and moisture and ensure high degree of purity in the CNG at Filter outlet. The gas flowing out of DELTA CNG Filters Outlet Port meets the following specs
Particulate Removal: Down to 0.1 micron, 99.5% Efficiency, i.e. Highest degree of cleanliness
Oil & Condensate Removal: Down to 0.01 ppm, residual oil content i.e. oil free CNG for fueling vehicles
Filter Vessel MOC in SS304. SS316 and SS316L options are available. See Catalog for larger models.
SS316 CNG FILTERS, 300 CLASS FLANGED, 25 BAR TEST PRESSURE
DELTA DUPLEX FUEL GAS FILTERS
Duplex Fuel Gas Filters: Fuel Gas applications are critical for running a Plant in terms of non-stop operation. Fuel typically feeds a Gas Engine or a Gas Turbine. In such situations it is imperative to have 100% availability. DELTA Duplex Fuel Gas Filters serve this purpose. Duplex Fuel Gas Filters consist of 2 x 100% capacity Fuel Gas filters mounted in parallel. Duplex Fuel Gas Filters are configured with 2 + 2 changeover valves. With safety valves, drain and vent. Front panel designed to display pressure, temperature and differential pressure readings. Duplex configuration enables continuous operation without any downtime for change of filter elements. When the 1st Fuel Gas Filter is taken off-line for maintenance, the 2nd Fuel Gas Filter is valved-in to permit non-stop operation. DELTA Duplex Fuel Gas Filters are employed in various Gas Engine and Gas Turbine applications. Contact firstname.lastname@example.org for more details
