Building energy savings into your process

Did you know that compressed air generation can amount to over 40% of a plant’s total electricity bill? And that energy consumption can account for over 80% of a compressor’s lifecycle cost? For businesses serious about increasing their profits, energy consumption is an obvious target. It was therefore one of the leading design priorities for our ZT 30-50 VSD⁺ compressors.


Energy-saving components Our engineers took every opportunity to reduce energy consumption in these machines. The patented elements are designed in-house for maximum efficiency. A superior coating on the active surfaces of the stainless steel rotors contributes to the most efficient oil-free tooth technology in this capacity range. A unique Z seal design further reduces running costs and guarantees 100% certified oil-free air for your application. Element – In-house designed. – Maximum efficiency of the working area. – 40% increased lifetime. – Unique Z seal design. – Atlas Copco superior rotor coating for high efficiency and durability. Motor – IP66 oil-cooled Permanent Magnet Motor with oil-lubricated bearings. – Class-leading efficiency (IE5 – 97%) and rock-solid reliability. – Full regulation between 15 to 100% of the maximum capacity ensuring energy savings at lower compressor air demand. Neos Next – Exceptional piece of engineering, developed in-house. – With an IP54-rated protection from dust and dirt. – Operates dependably in hot conditions : up to 50°C /60°C by de-rating. – Entire electrical cubicle in one compact unit. VSD cooling fans The completely redesigned cooling air flow supported by a VSD cooling fan ensures maximum energy savings at lower RPMs. Plug & play – Integrated rotary drum dryer option (iMD) for moisture sensitive applications. – The Z VSD+ iD integrates a refrigerant dryer inside the compressor canopy.

VSD⁺ with dual NEOS drives

Atlas Copco pioneered VSD technology in the compressed air industry to offer major energy savings while protecting the environment for future generations. Today, we offer the widest range of integrated VSD compressors on the market.

VSD technology automatically adjusts the motor speed to air demand, reducing energy consumption by up to 35%. For the ZT 30-50 VSD⁺ range, we added a specially designed NEOS inverter to constantly optimize the motor speed, and our own Permanent Magnet Motor for class-leading efficiency.

Featuring dual NEOS drives, the ZT 30-50 VSD⁺ range has the widest operating range on the market. The units can operate from 28 to 100% load without wasting energy from unloaded operation, resulting in huge energy savings during periods of low to medium air demand. The dual NEOS drive system also keeps the compressor working at optimal efficiency – at any pressure – consuming less energy than a standard fixed speed machine or a VSD machine with a fixed gear ratio.

Optimized air flow

The ZT VSD⁺ brings cool, dense air into the package for optimal compression efficiency. Carefully designed coolers and strategically positioned piping and components minimize pressure drop in the package, while zero-loss drains ensure that no compressed air is wasted.

Advanced control algorithms

Advanced algorithms control your equipment to save energy when demand is low. For example, timer functions can stop your machines at night and during the weekend if no compressed air is needed. Alternatively, a dual pressure band can be implemented with lower pressure settings for these periods.
