PREMIUM ENGINE PROTECTION
Air inlet filtration systems are essential for the operation of gas turbines and other turbo machinery. As the demand for gas turbine thermal efficiency escalates with firing temperatures increasing and machine tolerance decreasing, gas turbines become more sensitive to particles in the combustion air. This leads to requirements for more efficient and reliable air filtration equipment.
Engine availability is also a main concern for power producers and operators in the oil & gas industry where frequent maintenance or unplanned stops are extremely costly. The need for longer service intervals and higher output is forcing operators to optimize their air inlet systems, in both short and long-term perspectives.
To meet increasing demands for performance and power output, Camfil has developed a new design meeting all the requirements of the latest gas turbines, diesel engines and compressors while maximizing power output and minimizing costs – the CamGT 3V-600.
The CamGT 3V-600 has a solid 600 mm deep frame, which allows for unparalleled media area. Each filter grade is aerodynamically optimized in order to provide the lowest possible pressure drop and longest available life.
Upgrading your inlet system with (H)EPA CamGT 3V-600 can eliminate compressor washing, extend turbine life, and reduce total cost of ownership.
The filter has a solid, airtight frame and a new technique for fixing the media to the frame; the double-sealing design. The same bonding technique is used in ULPA-class cleanroom filters, with the filter media packs glued onto a plastic container firmly fixed to a durable plastic frame. The double sealing prevents air bypass– a common phenomenon in ordinary inlet air filters that allows salt as well as coarse and submicron particles to bypass the filters. The end result is fouling, wearing down of turbine components and unnecessary and expensive downtime.
Superior Engine Protection
Operators typically specify a minimum of F9 efficiency or preferably stepping up to the EPA class range from E10 to E12 (EN 1822) which has a dramatic effect on engine fouling. With E12 efficiency we have taken the step into the "clean-room" world which enables operation periods of 2-3 years between shutdowns for water washing or filter replacement.
The CamGT is available in a range of efficiencies to meet individual requirements from F9 to E10-E12 EPA grade filters.
FOR SAFE OPERATION
A gas turbine filter is sometimes exposed to extreme peaks in pressure drop, and so to prevent the media from bulging or bursting aerodynamic grids are added to the air exit sides.
To ensure the best possible protection, the CamGT 3V-600 has been tested under extreme conditions. Our specialized gas turbine test rig simulates the harshest environment with simultaneous heavy dust load, high humidity and high salt concentration. Combined with the new solid frame, the filter withstands a continuous pressure drop of over 8000 Pa under these extreme conditions.
On March 8th, 2016, Camfil Power Systems together with 3rd party testing facility DNV, witnessed the CamGT filters successfully withstand 8000Pa or 300kg of pressure (the testing rig’s max. cap.) during a wet strength/wet burst test (meaning they were submerged under water for 12 hrs before testing). The test is valid for the product families CamGT 3V-600 (E12 tested) & 4V-300 (E10 tested); both product lines were awarded a Wet Burst Test certificate each.
Resistant to Humidity
The CamGT’s large filter surface is based on Camfil’s patented construction featuring vertical pleating and hot melt separators for optimum water handling.
The CamGT’s construction allows trapped water to drain freely from the filter during operation, thus avoiding re-entrainment of dissolved impurities and maintaining low pressure drop under high humidity conditions.
