Atlas Copco ZR-ZT 110-275/132-315 VSD oil-free screw air compressor

​Product Core Positioning and Industry Applications

Core advantages

Class 0 Zero Oil Air: Tested by T Ü V, compressed air is free of oil (aerosols, liquids, oil vapors), eliminating the risks of product contamination, shutdown and scrapping, and brand reputation loss;

High reliability: 60 years of oil-free screw technology accumulation, following ISO9001, ISO14001, ISO22000, OHSAS18001 quality systems; Long overhaul intervals and low maintenance frequency;

High energy efficiency: High flow FAD free air output, low energy consumption, large-sized cooling system, low pressure drop, and high-efficiency transmission assembly improve overall efficiency; The VSD frequency conversion version can save up to 35% energy and reduce the overall lifecycle cost by an average of 22%;

Integrated full function FF kit: the whole machine integrates pipelines, coolers, motors, lubrication, and control systems; The FF version is equipped with an IMD adsorption dryer, which is plug and play from the factory and does not require external instrument air supply, reducing on-site installation and debugging workload.

Target industry

Food and beverage, textile, oil and gas, power plants, as well as pharmaceuticals, semiconductor electronics, medical, automotive spraying, chemical and petrochemical industries.

Food and beverage: fermentation, packaging, transportation, filling and cleaning, instrument gas;

Oil and gas: instrument/buffer gas source;

Power plant: Continuous operation conditions of flue gas desulfurization, oxidation air, and fluidized bed.

Model differentiation: ZR (water-cooled)/ZT (air-cooled)

ZR water-cooled model

Loading unloading adjustment of intake throttle valve, without the need for external air source; The intake and exhaust valves are mechanically interlocked, resulting in low unloading power consumption;

Z-sealed rotor component, special rotor coating, water-cooled jacket;

Stainless steel heat exchange pipelines, robot welding, aluminum star shaped inserts for enhanced heat exchange; Maze type water vapor separator reduces the liquid carryover of compressed air and protects post-treatment equipment;

IE3 high-efficiency fully enclosed IP55 TEFC motor.

ZT air-cooled model

Soundproof chassis, with forklift holes reserved on the base for easy handling, and the air duct can be connected to an external exhaust duct;

Two stage intake filtration, with a filtration efficiency of 99.9% for 3 μ m dust and low pressure drop;

IP55 protection efficient motor, VSD model can operate continuously in harsh environments, with an adjustment range of 30-100% rated capacity;

FF version integrated IMD adsorption dryer: using the compressor’s own compression heat regeneration, no external energy required, almost no compressed air loss, extremely low pressure drop, producing dry and clean compressed air.

IMD drying principle: Directly utilizing the heat generated by the compression process to regenerate the adsorbent, without the need for electric heating, dehumidification is completed before the compressed air enters the pipeline network.

VSD frequency conversion technology (ZR-ZT VSD version)

Energy accounts for about 80% of the total lifecycle cost of an air compressor, and the VSD frequency converter adjusts the motor speed in real-time according to the gas consumption.

Energy saving: up to 35% energy saving, with an average reduction of 22% in total cost throughout the system lifecycle;

Flexible and adjustable pressure of 4-10.4 bar; The pressure of the pipeline network can be stably controlled within ± 0.10 bar fluctuation;

Whole machine (integrated control of controller and frequency converter), EMC electromagnetic compatibility certification;

Specially adapted for motor and bearing protection under variable frequency conditions; Can work stably at an ambient temperature of up to 50 ℃;

The wide adjustment ratio is 70-75%, and there is no disabled speed window, which will not damage energy saving and pressure stability.

4 Elektronikon ®  MK5 control system (i.e. the controller corresponding to the previous document manual)

5.7-inch color display screen, supporting 31 languages;

Control the main motor, pressure regulation, and dryer to achieve maximum energy efficiency of the entire machine;
