The Atlas Copco ZR 30 is the water-cooled fixed-speed entry of the oil-free rotary tooth range, rated at 30 kW \/ 40 hp for 7.5 and 8.6 bar(e) networks. Free air delivery peaks at 78.8 l\/s at the 7.5 bar working point. The compression chambers run completely dry, and T\u00dcV has verified the ISO 8573-1 CLASS 0 certification for total oil content.<\/p>\n

Water cooling shapes the character of this machine. The heat of compression leaves through a closed water circuit instead of being blown into the compressor room, and the sound pressure level reads 63 dB(A) at 50 Hz. The sections below cover the rated data at both supply frequencies, the way the water circuit and the dry tooth element work together, and the builds that tailor the ZR 30 to a plant.<\/p>\n

A Fixed-Speed Machine Built Around the Water Circuit<\/h2>\n

The ZR 30 is the fixed-speed member of the oil-free tooth family at 30 kW. Its drive train pairs a super premium efficiency IE4 class motor with a gear box design chosen for extreme reliability, a mechanical layout that suits plants whose air demand sits at a steady level through the shift. Where the consumption barely moves, a fixed-speed compressor delivers its certified volume hour after hour without the control hardware of a variable drive.<\/p>\n

The position of the ZR 30 in the plant is just as specific. It is the machine for compressor rooms that already hold a cooling water network from chillers, process equipment or a closed loop. The ZR 30 connects to that network and hands the heat of compression to the water instead of the room air. Plants without a water main install the air-cooled ZT 30 of the same family instead.<\/p>\n

Inside the fixed-speed control, the machine works on a load and unload principle. When the network reaches the unload pressure, the ZR 30 stops compressing and keeps the motor ready for the next demand spike. The Elektronikon algorithms decide how long the machine idles and when it stops completely, which protects the motor from frequent starts and keeps the energy bill of the idle phases under control. For a workshop that runs one or two shifts at a predictable level, this control logic stays simple to run.<\/p>\n

The ZR 30 measures 2005 \u00d7 1026 \u00d7 1880 mm in every build, so the footprint stays constant from the first quotation to the final installation. The integrated dryers add their weight inside that same outline.<\/p>\n

How the Water Circuit Works<\/h2>\n

Three coolers sit inside the ZR 30: an oil cooler, an intercooler and an aftercooler, built as sturdy tube and shell heat exchangers. The cooling system runs three parallel circuits, so the oil, the intercooler stage and the aftercooler stage each receive water at the level their design asks for. The heat of compression travels into the water and leaves the machine room entirely.<\/p>\n

No fan has to push cooling air across the exchangers, and that single fact explains the acoustic signature of the ZR 30. The 63 dB(A) sound pressure level at 50 Hz allows an installation next to the work floor without a separate compressor room. Plants can also route the warmed water to heat recovery duties such as washing water or space heating, turning part of the compression energy into a utility the site already uses.<\/p>\n

The installation side follows the same logic. A water shut-off valve in the option list isolates the machine for service without touching the rest of the network, and the water connections sit within reach along the frame. Because the ZR 30 measures only 2005 mm in length, the machine fits into rooms where every metre of wall has already been planned. The condensate from the moisture separation system and the aftercooler drains at dedicated points, ready for the site’s condensate treatment.<\/p>\n

The Tooth Element and Certified Class 0 Air<\/h2>\n

Air enters the ZR 30 through the inlet filter with its integrated blow-off valve, which handles the load and unload regulation of the fixed-speed control. The first compression stage raises the pressure to an intermediate level, the intercooler removes the heat, and a moisture separation system drains the condensate before the air reaches the second stage. An aftercooler conditions the flow before it leaves through the outlet.<\/p>\n

The oil-free tooth technology holds a very competitive position among dry compression systems in this power range. No oil enters the compression chambers, and the lubrication for gears and bearings runs in a circuit of its own. T\u00dcV tested the machine and awarded the ISO 8573-1 CLASS 0 certification for total oil content. Food and beverage plants read this result together with the ISO 22000 food safety management that backs the production of the range.<\/p>\n

Two compression stages also keep the temperatures inside the ZR 30 moderate. The intercooler between the stages removes the heat of the first compression before the second stage starts, so neither stage has to bridge the full pressure ratio in one step. Lower stage temperatures protect the element over long running hours and support the dry compression principle, because no oil film has to carry the heat away from the rotors.<\/p>\n

Pack or Full Feature with Integrated Dryers<\/h2>\n

The Pack build ships the ZR 30 with its soundproof canopy and the Elektronikon controller. The Full Feature builds move the air treatment into the same frame. The ID build integrates a refrigerant dryer for a stable pressure dew point on general plant air, and the iMD build integrates the rotary drum dryer that regenerates with hot compressed air and reaches dew points far below what a refrigerant circuit achieves.<\/p>\n

The option list supports this air-quality side with an integrated dryer bypass, a silicone-free rotor for MD service and a water shut-off valve. All of them stay inside the 2005 \u00d7 1026 \u00d7 1880 mm outline of the ZR 30.<\/p>\n

Service follows the compact layout as well. The dryers, the coolers and the element sit behind removable panels, and the Elektronikon display reports the component status that the service organization needs before a visit. A machine that holds its air treatment in one frame gives the maintenance team one place to work, and the ZR 30 was laid out exactly for that purpose.<\/p>\n

Elektronikon Control for Fixed-Speed Duty<\/h2>\n

The Elektronikon monitor runs the load and unload control of the ZR 30 and adds algorithms aimed directly at fixed-speed economics. Delayed Second Stop keeps the motor from restarting too often when demand flickers around the unload pressure. The dual pressure band drops the settings during nights and weekends, when the required pressure sits lower, and the timer function parks the machine in shutdown windows.<\/p>\n

Rooms with three or more compressors gain from the central control tiers: the built-in EQ4i or EQ6i algorithms, the Equalizer 4.0 sequencer and the Optimizer 4.0 controller. SMARTLINK connects the ZR 30 to energy reports and early warnings. Anchor pads, ANSI flanges, a main power isolator switch, anti-condensation heaters and thermistors, an IT variant and a test certificate round out the option list.<\/p>\n

Where the ZR 30 Fits<\/h2>\n

The machine serves any process that calls for certified oil-free air at a steady demand around the 30 kW mark. Food and beverage lines value the Class 0 certificate together with the ISO 22000 background. Laboratories, electronics assembly and pharmaceutical areas take the clean, dry output directly into their processes. Sites with an existing cooling water network install the ZR 30 without extending their ventilation, and the quiet signature allows a place on the production floor itself.<\/p>\n

The ZR 30 also grows with the plant. The same fixed-speed tooth family continues with the ZR 37 and the ZR 45, so a second machine of the next size shares the water connections, the control platform and the service concept. Plants that plan their compressed air in steps therefore stay inside one hardware environment while the demand rises.<\/p>\n

For plants whose demand moves strongly between shifts, the ZR 30 VSD+ generation<\/a> of the same tooth family covers the same pressure range with variable speed control. For steady loads in water-cooled rooms, the ZR 30 remains the direct answer.<\/p>\n
