Oil-Free Air Centrifugal Blowers ZB 5-6 VSD+

Atlas Copco ZB VSD+ High-Speed Magnetic Bearing Turbo Blowers

With its new generation of ZB magnetic bearing turbo blowers, Atlas Copco releases one of the most efficient oil-free turbo blower in the market in all aspects. Paired with the highest efficiency, the ZB range proves an uncomparable reliability and lifetime with its unsensitivity to process changes.

The Atlas Copco ZB VSD+ high-speed magnetic bearing turbo blower combines oil-free air technology, variable-speed control, and high-speed magnetic bearing technology to provide an efficient solution for low-pressure industrial applications.

With a power range of 120–250 kW, airflow of 21.7–200 m³/min, and pressure range of 0.3–1.4 bar(e), the ZB VSD+ is designed for applications where energy efficiency, reliable operation, and clean compressed air are essential.

As no air is used from the system to operate the machine, pressure variations will not trouble the operation of the blower at all. This technology combined with the fact that no power bank is needed in case of power failure makes the Atlas Copco ZB one of the most straight forward magnetic bearing blower ever made.

The ZB range: a reliable solution for your applications

Not only the active magnetic bearing technology but also its complete design makes the ZB range one of the most reliable turbo blowers in the market, insuring a perfect fit for all your low pressure applications.

Wastewater treatment

The ZB blowers have a very wide flow and pressure operational range, making them suitable for different wastewater treatment applications. Typically, the major energy consumers in these plants are the blowers. ZB however helps you to reduce your energy bill significantly thanks to the efficient impeller and bearing design.

Pneumatic conveying

Conveying is a delicate process which needs 100% clean oil-free air for trouble-free and continuous operation. The ZB blowers are a perfect fit for this kind of applications, ensuring energy-efficient Class 0 certified oil-free compressed air you can rely on.

Food and beverage

The ZB provides 100% pure oil-free air for all kinds of applications in the food and beverage industry such as fermentation, packaging, aeration for wastewater treatment purposes. Class 0 certified ZB blowers avoid compromising the purity of your end product and ensure zero risk of contamination by ensuring no oil is added during the compression process and thus delivering you 100% oil free air if the atmosphere doesn’t contain any oil particles.

Flue gas desulphurization

In coal-fired power plants, who are running 24/7, the compressed air solution needs to be highly reliable and no downtime can be permitted. With the ZB blowers, you don’t need to worry about this. They are designed to offer a constant reliable air flow at minimal energy cost.

Key Features

1. Protecting electrical cubicle

• Separated from the mechanical components to ensure proper cooling and compactness.
• Includes all necessary components to protect the machine as well as the complete electrical network (RFI filters, AC choke, LC filters, sine filters etc.).

• Temperature controlled with integrated cooling fan and heating system to maintain a constant temperature in all conditions.

2. Compact and low heat rejection frequency drive

• The high-frequency variable speed drive is the component ensuring the motor’s optimum operation.
• Water-cooled, it provides mimum rejection and is the most compact as well.

3. Magnetic bearing controller

• Compiles information from position sensors to dynamically adjust the shaft’s position.
• Full control of the rotor is guaranteed by the magnetic force adjustment.

• No external source required nor UPS in case of power failure. Energy is pulled from the variable frequency drive through aDC/DC converter.

4. Minimum internal temperature with heatsink cooling fan

• Reduces cooling water temperature for the permanent magnet motor and drive.
• Cools down mechanical components inside the machine to ensure the lowest operating temperature and longest lifetime.

• Centralized warm cooling air to one single common location on the machine’s roof to ease ducting and heat extraction.

5. Actuated modulating blow-off valve

• Integrated and factory mounted modulating blow-off valve protecting the blower from overheating.

• Advanced control algorithm which allows the machine to run in the most efficient way in an extended operating flow range(from 100% to 0% turndown).

6. Integrated blow-off silencer

• Integrated and factory mounted blow-off silencer to reduce noise from blow-off operation.

• Attenuated noise through built-in internal turns.

7. High-efficiency process air filters

• Separated process air path to ensure lowest intake temperature and highest mass flow.
• Parallel high-efficiency filters
• Easily accessible from the back of the machine and replaceable.

8. Separated process air inlet

• Manifold leading air directly from intake point to blower’s impeller to separate it from internal heat

• Maintains the process air temperature to a minimum to increase mass flow delivered by the blower.
