3-20 HP Rotary with Dryer
Kaeser Airtower

Challenge: How to maximize the compressed air capacity and the benefits of a refrigerated dryer into a cost-effective, space-saving package.

Myth: Packaged systems interfere with the ability to perform maintenance on the air compressor separately from the dryer.

Learn from us: The Kaeser Airtower package combines an air compressor and dryer in a unique way. Although they are a "package" with a common footprint, they are not enclosed in a common enclosure. Each has its own control cabinet, which has the advantage of the compressor and dryer operating separately. This makes it possible to service the dryer while the compressor is still running, for example. As with all of the well-engineered Kaeser package systems, the compact design does not interfere with maintenance and service requirements. Everything is easily accessible for access to perform maintenance.

Hope Air Systems responds: The Kaeser Airtower design also benefits from the innovations from Kaeser that contribute to energy savings, increased operating efficiency and ease of control. The Airtower airend is equipped with rotors featuring the energy-saving Sigma Profile. Manufactured according to strict quality standards and supported by precision-aligned roller bearings, they guarantee long operational life and outstanding reliability.

The Airtower is immediately ready for operation by connecting the pressure hose from the ball valve to the air receiver. The compressor controller is based on a rugged, updateable industrial computer with a real-time operating system. Traffic light LEDs clearly indicate the operational status at all times.
