The Model 494 Compressed Air Treatment System (CATS) is designed to supply clean, dry air for any offshore applications. The system is usually supplied as part of a purged/pressurized (Ex p) swivel to ensure the purge control system has a good air supply. Operating pressure is typically 125 psi [8.5 bar]. Flow rates are determined by the customer requirements. Output air is Class 2 in accordance with ISO 8573-1.

While the CATS is typically used with an Ex p swivel, it can be used for any application that requires a source of clean, dry air.

The system can be supplied with a pneumatic system that will automatically use a compressed gas bottle as a secondary supply should the primary supply fail. This will keep a pressurized swivel operating with a loss of primary air.

The components of the CATS are housed in a 316 SS enclosure. External to the enclosure is the air input/output connections. Ingress protection is IP66.

All 400 series products are intended for use in Floating Production Systems (FPS). They are well suited for any application requiring a product that can withstand harsh marine conditions or require long life with minimal maintenance intervals. Designed and manufactured in our ISO 9001 facility under our project management system, products have a two year warranty and are provided with a complete document package.

All products can be modified to meet specific requirements. Installation, commissioning and service is available.
