Two-stage variable speed air compressors ULTIMA series

Scroll Oil free variable speed Screw Air Compressor

From 75 to 160 kW U75-U160           
Ultima™ - The revolution in energy efficiency!

Ultima ™ is a groundbreaking 'PureAir' air compressor for the production of 100% compressed air free of oil and silicone, ideal for applications where air quality is a key success factor such as food, beverages, medicines, electronics and automotive.

Innovation from CompAir's brand-new Ultima αερο air compressor range lies in the compact construction of a fully soundproof air compressor assembly (just 69db!) Consisting of two stand-alone compressor stages, a low-pressure direct-current, high-pressure direct-current transistor. The compression elements move independently, at optimum rotational speed, offering throughout the range of delivering superior levels of energy efficiency over traditional oil-free technologies.

 

 

 

 

 

 

 

 

 

Ultima™ - the real deal

 

Considering that the highest cost in the lifecycle of a compressor is the energy to run it, the unique design of Ultima has allowed us to combine the ultimate performance with the ultimate efficiency, and still deliver a footprint 37% smaller than a conventional two-stage oil-free compressor. This allows easy installation in the smallest possible space – more than a benefit where space is limited – it is a real property cost saving.

Unique advantages comparing to conventional oil-free air compressors

1. 100% oil and silicone free - Highest levels of air quality
2. The only one in his class oil-free air compressor with heat recovery
3. 13% higher efficiency
4. Up to 45% lower energy consumption at offload operation
5. Up to 4.4 m3 smaller footprint
6. Noise level < 70 dBA - lowest in the market!
7. Easy installation - No ducting required
8. Available with iConn remote monitoring - IoT connected

Ground breaking design

Traditional oil-free compressors are driven by a single motor using a gearbox which in turn, drives both the low and high pressure airends. Gearboxes require oil and create friction which equates to energy loss. Ultima uses ultra high efficiency motors which replace the gearbox and the single motor which optimise performance throughout the complete volume range, as the airends can be driven at different speeds dependant on the demand. With a single motor driving both airends together this is not possible. This is where Ultima is hard to beat.

 

 

The Ultima design utilises an intelligent "digital gearbox" design which continuously monitors and independently adjust the speeds of each airend, ensuring maximum efficiency and pressure ratios at all times.

When any regulated speed compressor gets to the minimum speed, it goes into idle run. For any compressor, this is wasted energy. Ultima uses 45% less energy in idle run than a conventional two-stage compressor and a 160kW compressor uses only 8 kW in idle run.

 

Advanced DELCOS XXL controller

 

The Delcos XXL with its high resolution 8-inch colour touch screen display, is extremely user-friendly and self-explanatory. All functions are clearly structured in five main menus and are intuitively visual. The multilingual Delcos XXL control system ensures reliable operation and protects your investment by continuously monitoring the operational parameters, essential for reducing your running costs.

Ultima, through the controller, is iConn-ready. iConn is the all new and smart, proactive real-time monitoring service that delivers in-depth and real-time knowledge on the system to our compressed air users. It enables accurate production planning and total peace-of-mind protection, generating insight and statistics that keep users informed on performance, at the same time highlighting potential issues before they become a problem.
