CompAir Ultima Series
CompAir Ultima is CompAir’s flagship oil-free range, covering 55 to 160 kW. It is 100% oil and silicone-free, built for applications where air purity is not negotiable – food and beverage, pharmaceutical, electronics and medical.
What makes Ultima different
A conventional two-stage oil-free compressor uses one motor and a gearbox to drive both airends, and that gearbox costs efficiency in friction and wear. Ultima removes it. Each airend has its own variable-speed permanent magnet synchronous motor, with an electronic control system acting as a digital gearbox – so the pressure ratio between the two stages adjusts in real time to match demand.
The result exceeds IE5 and IES2 efficiency standards, and the gap is widest where most compressors spend their day: at idle. A 160 kW Ultima draws under 8 kW unloaded, roughly 45% less than a conventional two-stage machine.
Specification
Power: 55 – 160 kW
Noise: 69 dB(A) at 160 kW water-cooled, 70 dB(A) air-cooled
Idle consumption: under 8 kW at 160 kW
Footprint: 34% smaller than the previous generation, up to 50% smaller than competing models
Heat recovery: hot water up to 90°C on all models
Control: Delcos XL SE7 controller with iConn remote monitoring and predictive maintenance
Airends: German-engineered, specially coated to hold efficiency over the machine’s life, with sealed-for-life bearings
Two things worth planning around
Heat recovery. All models can produce hot water up to 90°C from compression heat that would otherwise be vented. On a machine of this size that is a material reduction in site energy cost, not a rounding error.
In-built power upgrades. Output can be scaled up later without buying an additional compressor – no build lead time, no installation downtime. Useful if you are sizing for a site that is still growing.
Getting the specification right
Ultima installations are specified around duty cycle, delivery pressure and how demand varies through the shift, rather than picked from a list. Tell us your flow requirement, the pressure you need at the point of use, and what the air feeds, and we will size it properly.
