Description
Oil-Free Screw Air Compressor [Ultima Series]-[2 Stage] Product Details:
Choose oil-free and eliminate risk.
For many industries air purity is a critical factor where even the smallest drop of oil risks contamination that can have effects such as:
- Product spoilage
- Production downtime
- Damage to production equipment
- Damage to brand reputation
That’s why you need the risk-free solution provided by Gardner Denver EnviroAire Series compressors.
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 194F
- Heat recovery connections are standard on water-cooled machines, optional on air-cooled machines
High-Efficiency Water Cooling System allows for a Completely Sealed Enclosure
- Completely sealed package = lower noise level
- No customer ducting required = simple installation
- Up to 12% more heat available for heat recovery than competitive offering
Air Cooled with Heat Recovery: The Ultimate Efficiency
Unique Cooling Ultima’s innovative and patented closed package cooling system allows for the collection and recovery of up to 98% of the heat that is generated during the compression process. This energy can be harnessed to provide process water heating, reaching usable water temperatures of up to 185°F (85°C). In fact, Ultima is the first and only air-cooled, oil-free air compressor on the market, capable of utilizing heat recovery for process water heating. Ultima has the added benefit of “hybrid cooling mode” operation. Depending upon the most economic cooling method at the time (e.g., in the case of seasonally changing availability of cooling water) Ultima can operate in either air-cooled or water-cooled mode or a combination of both concurrently. By utilizing the superior design of the closed loop water system, Ultima requires no air for internal cooling. The unique design processes cooling air within the compressor. By utilizing a heat exchanger, the Ultima cools the internal air, then recirculates it via the base frame around the compressor. This also ensures that no dust or particulates can enter the inside of the compressor. As a result, installation is made easy with no requirement for ducting, compressor rooms can be kept to the minimum size, noise levels are greatly reduced, and machines can be easily installed at point of use.
Integrated Heat Recovery
Significant energy and costs savings can be achieved with Ultima’s efficient integrated heat recovery system. It can be either factory fitted or supplied as a retrofit kit including all necessary pipe-work and fittings.
Key Benefits: Ultima Series
- 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.
Lowest Sound Levels
The Gardner Denver Ultima Series compressors utilize high-quality, sound insulating enclosure panels and a completely sealed cabinet. These features reduce the sound levels and eliminate the need for a separate compressor room, saving money on installation costs and providing installation location flexibility.
