Atlas Copco’s standardized, direct driven, non-geared PolyBlock™ centrifugal turbocompressor delivers maximum reliability and availability for your plastics production. Custom-designed for maximum compressor efficiency and robustness in complex and rigid polyolefin processes.
Smart plug-in concept enables easy access to all rotating parts such as dry face seals, impellers, bearings or vibration probes
PolyBlock™ ensures high reliability with a cost-effective design
Decades of experience with critical components such as impellers, casings, guide vanes, shaft seals, gears and bearings
Entire compressor stage is designed to prevent that polymer dust settles on your equipment
Our impellers are custom-engineered to your specific process needs for optimum efficiency
PolyBlock™ is perfectly suited to handle your high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and polypropylene (PP) processes. PolyBlock™ is a cost efficient, highly reliable direct-driven compressor solution that improves the overall availability of your polyolefin plant.
Its smart plug-in design enables easy access to all rotating parts for maximum compressor maintainability at lower costs.
The PolyBlock™ design of critical components – such as shaft seals, gears and bearings – maximizes compressor robustness to ensure the stable gas supply critical for production. Dry face seals keep process gas within the compressor, minimizing leakage, and ensure all available power is utilized. Dynamically balanced impellers feature backward-leaning blades that are tested for efficiency and balance.
By purging the cavity of the inlet guide vanes with clean dry gas, this ensures reliable performance of the inlet guide vanes of the compressor and, ultimately, of overall plant production.
The standardized design of PolyBlock™ is a response to the market’s needs for reliable compressor solutions for the PP/PE industry. Our solution provides flexibility by offering you a number of standard features that can be added to meet your process requirements. At the same time, PolyBlock™ can meet your high-spec needs if required by the customer
With a significantly smaller footprint than its customizable counterparts, PolyBlock™ supports a maximum level of compressor maintainability to improve the overall availability of your plant.
PolyBlock™ operates in conformance with API 617, API 614, ERC Russia, CSA/CRN, as well as other codes and regulations.
