Безмасляный ротационный винтовой воздушный компрессор Atlas Copco ZT 200 VSD (FF VSD⁺)

Описание

The Atlas Copco ZT 200 VSD is the air-cooled entry of the ZR/ZT 200-355 VSD+ oil-free range, a 200 kW rotary screw compressor whose compression duty is split across two 100 kW modules. The compression chambers run completely free of oil, the package carries the ISO 8573-1 CLASS 0 (2010) certification, and the dual NEOS drives regulate the machine from 11 to 100 percent of load without ever running unloaded.

The single 10.4 bar(e) class covers free air delivery from 181 to 662 l/s across its minimum, effective and maximum settings. Air cooling rejects the heat of compression into the room air, which keeps the 200 kW installation free of any water dependency, and the Full Feature build with the iMD adsorption dryer integrates the drying function inside the same delivery.

Where the ZT 200 VSD Sits in the Oil-Free Range

The ZR/ZT 200-355 VSD+ range serves the plants whose oil-free demand has outgrown the 110-160 class and now runs continuously at industrial scale, and the ZT 200 VSD carries 200 kW of installed motor power at the entry of the range. The air-cooled machines of that previous line run the ZT 110 VSD. 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.

Atlas Copco pioneered oil-free air technology over sixty years and became the first manufacturer awarded CLASS 0 certification. The ZT 200 VSD brings that standard into the air-cooled 200 kW class through two identical compression modules that share the load, a design that keeps the elements compact, the rotors efficient and the service items grouped. Plants with a cooling water main on site run the water-cooled ZR 200 VSD of the same rating.

Минимальное, эффективное и максимальное

Each setting of the 10.4 bar(e) class works across a band, and each row of the official tables adds one fact:

• Minimum — the lowest working pressure setting, where the machine delivers its highest free air delivery for networks that run a wide pressure band.
• Effective — the nominal setting of the network, where the dual drives balance flow and pressure for the daily load profile.
• Maximum — the top working pressure of the class, where the package still delivers stable flow for the demanding corners of the plant.

Every setting combines with the standard Pack or with the Full Feature build that integrates the iMD dryer. The sections below present the rated data of each build in the printed 50 Hz and 60 Hz tables.

Technical Specifications of the ZT 200 VSD

The table below condenses the ZT 200 VSD into its headline figures:

Номинальные характеристики блока VSD+

Unit performance is measured according to ISO 1217, Annex E, edition 4 (2009), with free air delivery referenced to the effective working pressure. The 50 Hz table reads:

The 60 Hz table prints the same machine in psig and cfm with the motor rated in hp:

The noise level is the A-weighted emission sound pressure level at the work station, measured according to ISO 2151:2008 using ISO 9614-2, with a total uncertainty value of 3 dB(A). The Pack holds the value 78 dB(A), and the two modules deliver the installed power of 200 kW at 50 Hz and 268 hp at 60 Hz.

Технические характеристики полнофункциональной сборки iMD

The Full Feature build with the iMD adsorption dryer widens the minimum setting to 6 bar(e) and keeps the effective and maximum settings of the class. The 50 Hz table reads:

The 60 Hz table of the iMD build follows:

Across the printed settings the iMD build delivers up to 649 l/s at its widest band, and the sound pressure level holds at 78 dB(A) at the work station.

Размеры и вес

Two configurations cover the delivery of the ZT 200 VSD, and the air-cooled design carries the full cooler surface inside the package:

The Pack fits a 4.4-meter length, and the integrated iMD build stretches the frame to hold the dryer without changing the width or the installation logic. Neither branch needs a cooling water main, a water treatment line or condensation handling, so the machine room keeps its floor space for production.

Dual NEOS Drives and the Permanent Magnet Motor

The VSD+ concept of the ZT 200 VSD rests on two NEOS inverters that regulate the two compression modules together. The machine operates from 11 to 100 percent of load without wasting energy on unloaded running, the widest operating range on the market today, and the energy savings reach up to 35 percent during periods of low to medium air demand.

Because the dual NEOS drives replace the fixed gear ratio of standard fixed speed and VSD machines, the ZT 200 VSD always works at optimal efficiency at any pressure. The Permanent Magnet motor is oil-cooled with oil lubricated bearings, and its sealed construction prevents dust and water from entering the windings, a protection that suits the dusty air of heavy industry.

Air Cooling at 200 Kilowatts

Air cooling defines the ZT branch of the range, and at 200 kW the cooling circuit is engineered as carefully as the compression stage. High efficiency radial fans and the aluminium brazed heat exchanger keep the cooler approach temperatures low, the stainless steel precooler protects the aftercooler from heat loads, and the highly efficient water separator of the coolers raises the reliability of the whole circuit.

The air path runs through two compression stages: the air enters through the inlet filter, is compressed to an intermediate pressure, and flows through the pulsation dampener to the intercooler. An automated moisture separation system removes the condensate before the high-pressure stage brings the air to its final pressure. Zero loss drains clear all water and contamination from the circuit, so no compressed air is wasted at any drain point.

The Integrated iMD Dryer in the Air Flow

In the Full Feature build, the air flow splits into two parts. Some 60 percent of the flow is cooled in the precooler and aftercooler, where the moisture is separated and evacuated, while the second part flows directly to the regeneration area of the heat-of-compression MD dryer. The hot air regenerates the adsorption drum, passes the regeneration cooler, and mixes with the cooled main flow before the drying section, so dry air with a guaranteed dew point leaves the compressor through the outlet connection flange.

The whole drying function lives inside the compressor package, which saves the floor space of a separate dryer, removes the pressure drop of external piping and lets the Elektronikon controller manage the compressor and the dryer together.

Класс чистоты воздуха 0 для критически важных технологических процессов

The ZT 200 VSD belongs to the oil-free range certified according to ISO 8573-1 CLASS 0 (2010). 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. The unique Z seal design guarantees efficient and 100 percent certified oil-free air, because only oil-free machines exclude contamination risks 100 percent.

That certification is what makes the ZT 200 VSD 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, textile and chemical operations, and pharmaceutical production from fermentation to bottling.

Управление и мониторинг

The Elektronikon Mk5 Touch controller runs the compressor and the integrated dryer from one touch screen. The system saves energy with the delayed second stop that stops the compressor whenever possible, the dual pressure band that lowers the pressure of the network during weekends and nights, automatic main motor speed adjustments that follow the air demand, and dryer speed adaptation according to the actual need.

SMARTLINK connects the ZT 200 VSD to the monitoring platform of the plant. Customized reports show the energy efficiency of the compressor room, early warnings avoid breakdowns and production loss, and all components are replaced on time to ensure maximum uptime.

• Silicone-free rotor — for specified coating and process materials.
• Kit for purge of dry air during standstill — protects the elements in humid or intermittent duty.
• Anchor pads, IT network connectivity, wooden case protection packaging, test certificate and witnessed performance test — for controlled installation and documented acceptance.

A dedicated customization team designs engineered solutions for extreme temperatures and remote locations, and every option availability is confirmed against the chosen configuration before the order.

Applications of the ZT 200 VSD

Food and beverage plants run the ZT 200 VSD for fermentation, aeration, transportation, filling and capping, where the CLASS 0 certification removes the contamination risk from the audit trail. Foundries and metal plants value the air-cooled design in machine rooms without a water circuit, and textile mills use the clean, dry air for spinning and looms 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 of the network grows beyond one machine, the plant adds a second ZT 200 VSD, and the Optimizer central controller regulates the group as one unit with the narrowest pressure band.

Часто задаваемые вопросы

What does the ZT 200 VSD deliver at maximum pressure?

At the maximum setting of 10.4 bar(e) the Pack delivers 181 to 481 l/s, and across the full minimum-to-maximum band it covers 181 to 662 l/s. Free air delivery is referenced to the effective working pressure according to ISO 1217, Annex E, edition 4 (2009).

Is the ZT 200 VSD air-cooled?

Yes. The ZT letter marks the air-cooled branch of the ZR/ZT range: the cooling circuit rejects the heat of compression into the room air, so no cooling water main is needed. The sound level reads 78 dB(A), and the water-cooled equivalent is the ZR 200 VSD for plants that prefer a closed cooling circuit.

Насколько воздух очищен от масла?

The ZT 200 VSD carries the ISO 8573-1 CLASS 0 (2010) certification, the most stringent class of the standard. The Z seal design and the oil-free compression chambers keep every form of oil out of the air stream, so no oil carry-over reaches the process.

Что добавляет сборка «Full Feature»?

Full Feature integrates the iMD heat-of-compression adsorption dryer inside the package. The dryer regenerates with the heat of compression, so no external energy is needed, and the package weight grows from 6,560 kg to 7,792 kg while the length grows from 4,417 mm to 5,348 mm.

Насколько низко может опускаться машина?

The dual NEOS drives regulate the two modules from 11 to 100 percent of load without unloaded running, the widest operating range on the market. Because the dual drive design replaces the fixed gear ratio, the machine works at optimal efficiency at any pressure, and the energy savings reach up to 35 percent at low to medium demand.

How loud is the ZT 200 VSD?

The sound pressure level at the work station reads 78 dB(A). The value follows ISO 2151:2008 with the ISO 9614-2 method and carries a total uncertainty value of 3 dB(A).
