Atlas Copco ZR/ZT 15-55 (VSD) Oil-free Tooth Compressors

ECONOMICAL, HIGH QUALITY OIL-FREE AIR

Clean, oil-free compressed air is a prerequisite for the continuity and quality of many manufacturing processes. Over the past decades, Atlas Copco has pioneered the development of oil-free rotary tooth technology, resulting in a full range of highly reliable compressors delivering 100% oil-free, clean air. With the protection of your application in mind, the Atlas Copco ZR/ZT 15-55 (VSD) Oil-free Tooth Compressors (ZT 15-22, ZR/ZT 30-45, ZT 22 VSD, ZR/ZT 37-55 VSD) give you all of this experience in a class leading package and meets your every need for pure oil-free air.

100% oil-free air Your activities in pharmaceutical production, food processing, critical electronics or in a similarly exacting industry demand the best air quality for a guaranteed end product and production process. Designed with your specific applications in mind, our rotary tooth compressors eliminate the risks of oil contamination and the accompanying product spoilage, brand damage and delays that represent extra costs. Preventing oil from entering the compression process is a necessity for the generation of consistent 100% oil-free air. Certified ISO 8573-1 CLASS 0 by the renowned TÜV institute, the ZR/ZT ensure the safety of your application and at the same time allow you to enjoy lower operating and maintenance costs.
Reduced energy costs As energy accounts for more than 70% of a compressor’s lifecycle costs (LCC), its importance is obvious. The most cost-effective compressed air solution optimizes the pressure, volume and air treatment equipment for each production process. Our ZR/ZT compressors provide you with the ultimate all-in-one package to decrease your electricity bill by an average of 35%. To help you save energy, regardless of whether you require a low or high-capacity compressor, our VSD range has been expanded with the ZT 22 VSD and the ZR/ZT 55 VSD.

	Radial fan (only for ZT air-cooled) • Ensures the unit is cooled effectively. • Low noise.
1.Intercooler and aftercooler • Thanks to the vertical layout of the coolers, the noise levels from the fan, motor and element have been drastically reduced.	2.Two stage tooth element • Lower energy consumption compared to single stage compression 1 systems as no venting of the pressure is required. • Minimum power consumption of the unloaded state is reached rapidly.
3.Sound insulated canopy • No separate compressor room required. • Only available in WorkPlace Air System™ versions.	4.Induction motor • Flange-mounted for perfect alignment. • Available in two versions: IP54 for VSD models and IE 3/NEMA Premium for fixed speed models. • The dry motor coupling requires no lubrication, eliminating service requirements.
5.Air filter • SAE fine 99.5%; SAE coarse 99.9%. • Long lifetime and high reliability for long service intervals. • Combined air filter and silencer to ensure sound insulation.	6.Integrated VSD converter • High energy efficiency thanks to no load operation and oil vessel blow-off losses. • Operation in a narrow pressure band setting reduces the overall system working pressure.
7.Elektronikon® • Advanced Elektronikon® control and monitoring system, designed for integration in a (remote) process control system.	Integrated dryer • Saver cycle technology reduces the energy consumption of the integrated air treatment in light load conditions. • As the condensate separation is integrated, water separation is improved and the Pressure Dew Point (PDP) becomes more stable.
Electronic water drains • Mounted vibration-free on the frame. • Constant removal of condensate for improved water separation and extended lifetime of the compressor.

PROVEN TECHNOLOGY, MAXIMIZED EFFICIENCY

To provide you with top-quality, 100% oil-free air, our ZR/ZT series incorporate a range of advanced technologies. The unique rotary tooth element increases efficiency thanks to two-stage compression. As no venting of the pressure element is required, the energy consumption is considerably lower compared to single stage compression systems. With its symmetrical and dynamically balanced design, the double tooth element ensures an increased free air delivery and delivers consistent performance over time.

Rotors Stainless steel symmetrical rotors ensure perfect dynamic balancing and minimum bearing load to guarantee a long life span.Axial in- and outlet port The straight rotor design and the opposing axial in- and outlet port avoid axial load on element components, increasing element lifetime.Air-cooled design Cast teeth allow for efficient heat dissipation, eliminating the need for a complex cooling water system and ensuring greater reliability.Seals Two independent floating oil and air seals, separated by a neutral buffer area, safeguard the compression chamber from oil penetration.

The rotary tooth working principle

1.	2.	3.	4.
Atmospheric air is drawn through the inlet port into the compressor chamber as a result of the rotational action of the tooth rotors.	Air is trapped between the teeth of the male and female rotors.	Compression takes place. The male and female rotor turn towards each other, decreasing the free space, resulting in an increase in pressure.	The female rotor exposes the outlet port and the compressed air is delivered to the system.

Dryer Solutions for a Variety of Needs

Untreated compressed air contains moisture and dust particles, which can damage your air system and contaminate your end product. The resulting maintenance costs can far exceed the cost of compressed air treatment. Atlas Copco believes this problem is preventable and offers a complete range of air treatment solutions to protect your investment, equipment, production processes, and end products.
