Ultima™ – The real deal

Ultima: A Revolution in Dry Screw Compressor Technology

What makes the Ultima so unique?

• Most efficient two-stage dry screw compressor on the market
• Uses independent low and high pressure dry screw airends
• Each airend is individually driven by a variable-speed, permanent-magnet, water-cooled motor
• Each motor operates at 97% efficiency (greater than IE4)
• Large turn down range up to 70%
• Lowest unloaded power consumption - only 8 kW
• Significantly smaller footprint while maintaining 63-70 dBA noise performance
• Water-cooled or air-cooled, both with heat recovery options

Superior Heat Recovery

• All the major components in the Ultima are water-cooled providing more efficient performance
• Approximately 94% of the energy used in a compressor is converted into heat. The closed loop cooling system in the Ultima cools all of the major components, removing heat from the motors, inverters and airends
• Ultima cooling philosophy maximizes energy recovery from the complete compressor package
• Ultima recovers 98% of the heated generated (approximately 12% more than standard), which can be used for other processes, reducing the building HVAC load
• Outlet water temperatures up to 90^oC
• Heat recovery connections are standard on water-cooled machines, optional on air-cooled machines

• 100% Oil-Free  

Eliminates the risk of contamination

• 13% Higher Efficiency

The Digital Gearbox drives each airend individually, significantly improving performance over the complete turndown range

• Lowest Unloaded Power

Ultima uses only 8 kW when running unloaded as compared to >20 kW to conventional machines

• >97% motor efficiency

Permanent magnet synchronous motors provide >97% efficiency and compact size

• Up to 70% Turndown

Allows for a greater variation in demand without starting an additional compressor, saves energy

• Ultra Quiet: 63 dBA

Fully enclosed water-cooled package offers industry leading noise performance as low as 63 dBA

• 47% Smaller Footprint

Allows 3 machines to fit in the same space as 2 competitive machines

• 98% Heat Recovery 

Excess heat is recovered for use in other plant processes

• Easy Installation

No ducting required

Optimum heat recovery ultimate cooling

Using a closed loop water cooling system to cool all major components, and with separate water cooling for the inter and after coolers, Ultima compressors offer the highest outputs for heat recovery - approximately 10% more than comparable compressors on the market. Ultima also offers the option of air-cooling.

Premium productivity

Where the majority of oil-free airends on the market quickly succumb to performance deterioration, Ultima utilises German engineered and manufactured airends incorporating a special coating to ensure life-long protection of the compressor and maximum efficiency.
