Centrifugal and axial compressors are susceptible to surge, which can cause catastrophic damage to your turbomachinery train.


The Antisurge Controller

The antisurge controller is one of the most critical turbomachinery control applications that protect a compressor from surge, by continuously calculating the distance between the compressor’s operating point and its surge limit line. The controller modulates a recycle or blow-off valve to prevent the compressor’s operating point from reaching the surge limit. At the same time, the antisurge controller maintains other process variables within safe or acceptable limits.

MAS S.A offers field proven control and protection solutions for your compressor based on latest technology updates and algorithms. Our advanced algorithms ensure that the compressor operates at peak efficiency, while each stage is protected from potentially catastrophic surge events, per OEM’s specification.

A crucial fact that is sometimes ignored, is that anti-surge controls are largely depended on the hardware platform used. For this reason, MAS S.A uses only specialized hardware from leading manufactures, such as Woodward, which ensure the needed speed and the quality and reliability requirements of such systems.

At MAS S.A we secure that starting from a single stage air compressor all the way to multi-section side stream refrigeration compressors running in parallel, the CCC standard antisurge control application can be adapted to a wide range of process applications simply through configuration parameters.

PAGNI Emergency Generators System Upgrade Description unavailable Oil & Gas No matter what type of prime mover is driving your generator - be it steam/ gas turbine or a gas/ diesel reciprocating engine, MAS SA designs products to control speed, fuel, exhaust emissions and manage load that are tailored for your specific prime mover. Compressor station retrofit A Gas compressor station of a Middle East customer, comprised of 2 x RR AVON GTs with Dresser Rand Compressors. The units were over 20 years old and had reliability problems. Operators often faced unexplained trips but also faced difficulty in mainlining process operational levels. Prime power plant upgrades Prime Power plants are plants that are part of the grid capacity and are usually in continuous operation or operate for long periods. MAS undertakes the complete upgrade of such power plants on an EPC basis. PPC Chios Plant Upgrade Description unavailable
