Description
The Atlas Copco ZR 110 is the 110 kW water-cooled machine of the ZR/ZT 110-275 oil-free family, a fixed-speed compressor that delivers certified oil-free air with the heat of compression carried out by the cooling water circuit. The compression chambers run completely free of oil, and the package carries the ISO 8573-1 CLASS 0 (2010) certification verified by TÜV.
Three pressure versions at 50 Hz and three at 60 Hz cover free air delivery from 266.5 to 347.7 l/s, and the Full Feature build integrates the adsorption dryer on the same platform. The water-cooled design turns the compression heat into a resource instead of a loss.
Where the ZR 110 Sits in the Oil-Free Range
The ZR/ZT 110-275 family serves the plants whose oil-free demand has outgrown the compact 55-90 class but has not yet reached the ZR/ZT 300-750 machines, and the ZR 110 carries 110 kW of installed motor power at the entry of the family. The letter Z marks the oil-free architecture: the compression elements never inject oil into the air stream, so no oil carry-over reaches the process. Where the demand profile swings, the ZR 110 VSD of the same rating adjusts its speed continuously instead of loading and unloading.
Atlas Copco pioneered oil-free air technology over sixty years and became the first manufacturer awarded CLASS 0 certification. The ZR 110 brings that standard into the water-cooled 110 kW class, and the package arrives as a complete all-in-one installation: place it on a flat floor, connect the power line, the cooling water circuit and the air outlet, and push the start button. Lighter oil-free networks in the same family run the ZR 90.
Two Branches, One Platform
Two names describe the branches of the ZR 110, and each adds one fact:
- Standard — the compressor package delivers oil-free air for networks with external air treatment downstream, with the water-cooled design rejecting the heat of compression into the cooling water circuit.
- Full Feature — the package integrates the adsorption dryer, so dry air leaves the machine directly with no external energy spent on regeneration.
Every version combines with both branches. Plants that prefer air cooling instead of a water circuit pick the ZT 110 of the same rating.

Rated Data at 50 Hz
Unit performance is measured according to ISO 1217, annex C, edition 4 (2009). The 7.5 and 8.6 bar versions are measured at 7 bar and the 10 bar version at 9 bar:
| Version | FAD (l/s) | FAD (m³/min) | FAD (cfm) | Noise |
|---|---|---|---|---|
| ZR 110 – 7.5 | 318.2 | 19.1 | 674 | 69 dB(A) |
| ZR 110 – 8.6 | 286.1 | 17.2 | 606 | 69 dB(A) |
| ZR 110 – 10 | 266.5 | 16.0 | 565 | 69 dB(A) |
The 7.5 bar version leads the series at 318.2 l/s (674 cfm), and the 10 bar band delivers 266.5 l/s (565 cfm). The installed motor power stays at 110 kW across all versions, and the sound pressure level holds at 69 dB(A) at the work station.
Rated Data at 60 Hz
The 60 Hz versions cover three bands from 7 to 10.4 bar(e), and the motor is rated at 150 hp. The measurement pressures follow the same rule as at 50 Hz:
| Version | FAD (l/s) | FAD (m³/min) | FAD (cfm) | Noise |
|---|---|---|---|---|
| ZR 110 – 7 | 347.7 | 20.9 | 737 | 69 dB(A) |
| ZR 110 – 8.6 | 318.2 | 19.1 | 674 | 69 dB(A) |
| ZR 110 – 10.4 | 288.7 | 17.3 | 612 | 69 dB(A) |
The 7 bar version tops the whole series at 347.7 l/s (737 cfm). The noise level is the A-weighted emission sound pressure level at the work station, measured according to ISO 2151: 2004 using ISO 9614/2, with a total uncertainty value of 3 dB(A).
Dimensions and Weight
The Full Feature branch adds the integrated dryer in a longer frame:
| Branch | Weight | Dimensions (L × W × H) |
|---|---|---|
| ZR 110, Standard | 2,635 kg / 5,809 lb | 2,540 × 1,650 × 2,000 mm (100.0 × 65.0 × 78.7 in) |
| ZR 110, Full Feature | 2,880 kg / 6,349 lb | 3,440 × 1,650 × 2,000 mm (135.4 × 65.0 × 78.7 in) |
No foundations are required for either branch. The package installs directly on the flat floor of the compressor room, with the cooling water connections at the rear of the frame.
Class 0 Air Purity, Verified by TÜV
The ZR 110 belongs to the oil-free range certified according to ISO 8573-1 CLASS 0 (2010). TÜV type-tested the range with the most rigorous methodologies available, measuring all possible oil forms across a range of temperatures and pressures, and found no traces of oil at all in the output air stream. CLASS 0 is the most stringent class of the standard: the total oil concentration is as specified by the equipment user or supplier and more stringent than class 1.
That certification is what makes the ZR 110 the default choice where a single trace of oil costs a batch: food and beverage lines running fermentation, packaging and filling, electronics plants cleaning chips and boards, petrochemical operations in extreme heat and humidity, and pharmaceutical production from tablet coating to bottling.
Water Cooling and Heat Recovery
Water cooling defines the ZR branch of the family. The closed heat exchange path keeps the sound pressure level of the ZR 110 at 69 dB(A), two decibels below the air-cooled sibling, and holds the package stable in hot machine rooms because the cooling water carries the heat of compression out of the frame instead of the room air.
That recovered heat is an asset. The water-cooled design turns the compression heat into a source for process water, washing water or space heating, which raises the total energy efficiency of the site again instead of venting the energy into the machine room.
Full Feature: The Integrated Adsorption Dryer
In the ZR 110 Full Feature, the adsorption dryer eliminates the moisture before it enters the air net. The dryer regenerates with the heat of the compressor, so no external energy is needed to dry the air, and the savings against a conventional dryer are large. The pressure drop through the dryer is minimal, which cuts the operating cost again, and the whole drying function lives inside the compressor package instead of beside it.
Control and Monitoring
The Elektronikon unit controller runs the compressor and the integrated dryer from one control system. The display shows the running conditions with clear icons and intuitive navigation, monitors the maintenance status, and raises pro-active service indications, alarms for malfunctions and safety shutdowns. Built-in remote control and notification functions come as standard with ethernet-based communication.
SMARTLINK and Options
The option list of the ZR 110 tailors the package to the plant:
- SMARTLINK — online data monitoring of the compressed air system with warning indications and maintenance scheduling.
- Long duration particles filter and other air quality options — for specified coating materials and demanding purity targets.
- Wooden case packaging, material certificates, test certificate and witnessed performance test — for controlled installation and documented acceptance.
Every ZR 110 is shop-tested before it leaves the factory, and the witnessed performance test option documents the measured flow and pressure against the specification for the acceptance record of the project. Combined with the material certificates and the wooden case packaging, the package arrives ready for a controlled installation from the first day.
Applications of the ZR 110
Food and beverage plants run the ZR 110 for fermentation, aeration, transportation, filling and capping, where the CLASS 0 certification removes the contamination risk from the audit trail. Electronics manufacturers use the clean, dry air for removing microscopic debris from chip and board surfaces, and petrochemical sites value the machine’s ability to run in extreme temperatures and humidity conditions around the clock.
Pharmaceutical production completes the picture, from fermentation and tablet coating to packing and bottling, where 100 percent oil-free air protects both the process and the brand. Where the demand profile fluctuates heavily, the plant adds the ZR 110 VSD of the same rating next to this fixed-speed machine, and growing networks step up to the larger models of the same family.
Service and Support Around the ZR 110
The ZR 110 is built for long overhaul intervals, few service interventions and minimal maintenance cost, and every machine is tested before delivery to ensure it meets the specifications.

FAQ
What does the ZR 110 deliver at 7.5 bar?
The 7.5 bar version delivers 318.2 l/s at 50 Hz, which equals 19.1 m³/min or 674 cfm, measured at 7 bar according to ISO 1217 annex C, edition 4 (2009). At 60 Hz the 7 bar version reads 347.7 l/s (737 cfm).
Is the ZR 110 water-cooled?
Yes. The ZR letter marks the water-cooled branch of the ZR/ZT family: the cooling water circuit carries the heat of compression out of the frame, which holds the sound level at 69 dB(A) and enables heat recovery. The air-cooled equivalent is the ZT 110.
How oil-free is the air?
The ZR 110 carries the ISO 8573-1 CLASS 0 (2010) certification verified by TÜV, the most stringent class of the standard. TÜV testing found no traces of oil at all in the output air stream across the tested range.
What does the Full Feature build add?
Full Feature integrates the adsorption dryer inside the compressor package. The dryer regenerates with the heat of the compressor, so no external energy is needed, and the package weight grows from 2,635 kg to 2,880 kg while the length grows from 2,540 mm to 3,440 mm.
How loud is the ZR 110?
The sound pressure level at the work station reads 69 dB(A) on every version at both frequencies. The value follows ISO 2151: 2004 with the ISO 9614/2 method and carries a total uncertainty value of 3 dB(A).
Does the ZR 110 need a cooling water main?
Yes, the water-cooled design expects a cooling water circuit on site, and that circuit is what enables the heat recovery to process water, washing water or space heating. Plants without a water main pick the air-cooled ZT 110 of the same rating.
Antti Salo –
Our process water needed heating anyway, so the water-cooled ZR 110 was the right route to class 0 air at 110 kW. The package runs quietly at 69 dB(A), the pressure holds flat at 7.5 bar across two shifts, and the recovered heat feeds the boiler make-up line. Seadweer confirmed the Full Feature build with the integrated dryer and the delivery matched the specification exactly.
