CompAir Ultima oil-free compressor
Gardner Denver’s CompAir Ultima oil-free compressor has two high-efficiency, permanent magnetic motors that replace the traditional gearbox design. These two variable-speed motors are capable of achieving speeds of up to 22,000 RPM and directly drive the airend without the need for a gearbox.
The compressor uses water in a closed-loop circuit to cool a system’s motors and airends, which allows greater heat transfer and cooling efficiencies and ensures as little oil as possible is used in the system for assured air purity. Water-cooling also places less stress on these components, limiting the opportunity for any maintenance issues and reducing servicing costs.
The compressor is offered as standard from 75 to 160 kW, with each unit fully upgradeable between this kilowatt range. This means that if a site’s energy demands increase in the future, users can choose the optimal variant based on the increased capacity. There is no need to purchase a new compressor, eliminating the associated downtime or delivery wait that comes with upgrading to a new system.
It emits a noise level of 69 db(A), has a small footprint and can be installed easily at the point of use, rather than in a separate compressor room. Its efficient internal cooling also means adjacent compressors can be sited close to one another, optimising the space available.
It offers assured air quality and purity for those operating in production-sensitive environments, such as the food and beverage industry, electronics manufacturing and the pharmaceuticals sector.
