1 Three-stage compression The three-stage design of the ZH 350+ uses the best-performing technology currently available to achieve high thermodynamic efficiency and lower power consumption. A three-stage design is widely recognized as the most efficient design for achieving compression between 6 to 11 bar(e) / 90 to 160 psig with a turbo compressor, resulting in 4 to 9% more air flow per unit of power and a broader operating range. Coated stages and stainless steel diffusers provide excellent performance stability over time. Efficiency % Mechanical efficiency Aerodynamic efficiency Total...

Working principle The air enters the ZH 350+ via the air filter O and then proceeds through three stages of compression Q. After each stage, an inter- or aftercooler © cools down the hot air. After the third stage of compression blow-off O takes place before the check valve © and aftercooler to rapidly de-pressurize the compressor's internal air volume during unload transitions. The three stages of compression are driven by two high-speed motors O without a gearbox. The motors and frequency inverters © are cooled in two parallel streams by an internal closed water cooling system, which...

Optimize your compressor room Thorough assessment of air flow demand profiles in the industry reveal that they can be either stable with limited fluctuations, highly fluctuating and hence less predictable or a combination of both. In all these cases Atlas Copeo can offer you a suitable solution based on a combination of different compression technologies. Stable demand Highly fluctuating demand The ZH 350+ handles air demand fluctuations more effectively than turbo technology could up to now. Its fast transitions between load and unload operation eliminate the need for expensive blow-down...
