Atlas Copco pioneered oil-free air technology over sixty years and became the first manufacturer awarded CLASS 0 certification. The ZT 90 carries that standard into the air-cooled 90 kW class, and the package arrives as a complete all-in-one installation: place it on a flat floor, connect the power line and the air outlet, and push the start button.<\/p>\n

The ZT 90 belongs to the first compressor range in the industry certified oil-free according to ISO 8573-1 CLASS 0 (2010). T\u00dcV 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.<\/p>\n
That certification is what makes the ZT 90 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.<\/p>\n

Air cooling defines the ZT branch of the family. A stainless steel pre-cooler with fins handles the heat exchange with excellent transfer and easy access for cleaning, and low-noise, low-energy radial cooling fans reject the heat into the machine room. Because no cooling water circuit is needed, the ZT 90 installs where the water-cooled ZR 90 cannot: laboratory buildings, workshops and remote sites that run oil-free air on a power line alone.<\/p>\n
Built for High Ambient Temperatures<\/h3>\n
The ZT 90 is the branch of the family that carries the high ambient temperature version, required when the ambient temperature rises above 40 degrees Celsius. The HAT variant of the 8.6 bar band is rated for a maximum intake and cooling air temperature of 50 degrees Celsius, which keeps certified oil-free production running in hot climates and poorly ventilated machine rooms where a standard package would have to derate.<\/p>\n

In the ZT 90 Full Feature, the IMD adsorption dryer eliminates the moisture before it enters the air net. The dryer uses the heat of the compressor for regeneration, 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.<\/p>\n

Atlas Copco ZT 90 (4)<\/figcaption><\/figure>\n Applications of the ZT 90<\/h2>\n
Food and beverage plants run the ZT 90 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.<\/p>\n
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 ZT 90 VSD of the same rating next to this fixed-speed machine, and growing networks step up to the ZR\/ZT 110-275 class above.<\/p>\n
Service and Support Around the ZT 90<\/h2>\n
The ZT 90 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. A global service operation with field service engineers across 160 countries backs the installed base, and genuine Atlas Copco parts keep the package at its rated performance.<\/p>\n

What does the ZT 90 deliver at 8.6 bar?<\/h3>\n
The 8.6 bar version delivers 223.3 l\/s at 50 Hz, which equals 13.4 m\u00b3\/min or 473 cfm, measured at 8 bar according to ISO 1217 annex C, edition 4 (2009). The HAT variant of the same band reads 211.4 l\/s (448 cfm) for 50 degrees Celsius intake air.<\/p>\n
Is the ZT 90 an air-cooled machine?<\/h3>\n
Yes. The ZT letter marks the air-cooled branch of the ZR\/ZT family: a stainless steel pre-cooler with fins and low-noise radial fans reject the heat, and no cooling water circuit is required. The water-cooled equivalent is the ZR 90.<\/p>\n

The ZT 90 carries the ISO 8573-1 CLASS 0 (2010) certification verified by T\u00dcV, the most stringent class of the standard. T\u00dcV testing found no traces of oil at all in the output air stream across the tested range.<\/p>\n

FF integrates the IMD adsorption dryer inside the compressor package. The dryer regenerates with the heat of the compressor, so no external energy is needed, and the package grows from 2,050 kg to 2,650 kg and from 2,180 mm to 2,880 mm in length.<\/p>\n
What is the HAT version for?<\/h3>\n
HAT stands for the high ambient temperature variant, rated for a maximum intake and cooling air temperature of 50 degrees Celsius. It is required when the ambient temperature rises above 40 degrees Celsius, and the ZT branch is the one that carries it.<\/p>\n
How loud is the ZT 90?<\/h3>\n
The sound pressure level at the work station reads 76 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).<\/p>","protected":false},"excerpt":{"rendered":"
