ETC Class 0 oil-free screw
Oil-free rotary screw with electronic temperature control — Class 0 oil-free air for the most demanding lines, with VSD and medium-pressure variants.
Overview
ETC Oil-Free Rotary Screw Air Compressor
ADEKOM ET series oil-free rotary screw air compressor combines advanced oil-injected screw compressor technology with the European-engineered ETC oil-free conversion system to deliver high-purity, oil-free compressed air effortlessly. Innovative Oil-Free Conversion Technology At the heart of the ETC system is a proprietary, eco-friendly catalyst material that facilitates a catalytic oxidation reaction at a controlled reaction temperature. This process ensures: Complete Hydrocarbon Breakdown: Oils and hydrocarbons (C6+) in the compressed air react with oxygen (O2), breaking down into water (H2O) and carbon dioxide (CO2). Sterilization: High temperatures effectively eliminate microorganisms in the air. Ultra-Clean Air Supply: The resulting compressed air meets ISO 8573-1 Class 0 standard for oil-free air, ensuring the highest level of purity.

Product Features
State-of-the-art Compressor Airend
Optimal Energy efficiency and outstanding reliability is achieved from patented design third generation non-symmetric robust rotors, superior bearings and oil seal that help the compressor airend to operate with good dynamic balance, low vibration, low rotation speed and low noise level.
Energy Saving Electric Motor
T.E.F.C Highly efficient, totally enclosed fan-cooled (T.E.F.C.),IP55, class F electric motor can achieve high efficiency of 95.2% that brings an unprecedented level of energy saving. High quality high speed bearings from “SKF”are fitted for continuous trouble-free operation.
High Efficiency Air Cooler System
Big capacity models adopt double cooling fan design. The first cooling fan starts up with the compressor and the second one starts up only when the operating temperature exceeds 80℃ and it stops when goes back below 70℃ in order to save energy.
Intelligent control system
It is controlled by a microcomputer and runs fully automatically. It detects the exhaust pressure, temperature and other operating data. Through the joint action of the microcomputer controller, frequency converter and frequency conversion motor, it outputs a constant exhaust pressure for the user. When the air is not used for a long time, it can automatically shut down and restart when the air is restored, thus achieving the purpose of energy saving (frequency conversion model); Chinese and English display, with 12 important indicator warnings; the display screen displays pressure, temperature, maintenance reminders, high temperature and high pressure records of the operation history for maintenance and reference, and can provide manual and automatic control functions to maximize the reliable operation of the air compressor and increase its service life.
The catalytic conversion chamber
Inside the catalytic conversion chamber, it is full of catalytic which is solid, highly porous system of mega-, macro-and micropores. The high porosity means also a high surface area of approx..200m2/g. Chemical reaction the inside Eco Tec Converter is a physical-chemical process which uses this special catalyst to convert the oil and other hydrocarbons into water and CO2. After it has passed the Eco Tec Converter the quality of the absolutely oil free compressed air exceeds by the requirements of ISO 8573-1 class 1 standard.

High efficiency and energy saving inverter
Internationally renowned ABB flux vector control frequency converter - delivers high starting torque at low frequencies with minimized operating current. Energy-optimized operation: Automatically enters sleep mode and completely shuts down during low air demand, eliminating energy waste from prolonged lower limit frequency operation. Reliable load-start capability: Enables direct loaded restart without tripping when pressure falls below preset limits, leveraging the superior low-frequency starting performance of vector-controlled drives. Enhanced energy efficiency: Avoids unnecessary power consumption from extended minimum frequency operation. Intelligent cycling: Equipped with auto sleep/wake-up functions for adaptive energy management. Comprehensive protection: Incorporates multiple safeguards including over-voltage/under-voltage protection, drive overheat protection, and short-circuit protection.
High Efficiency Permanent Magnet Motor
IPM motor constructed with neodymium iron boron permanent magnet materials can prevent demagnetized even under high operating temperature up to 180℃. Services life is up to 15 years! Halo-resistance enameled cable with remarkable insulation performance is applied to stator coil for long service life. One common shaft structure design, motor without bearing structure to guarantee 100% transmission efficiency. No more greasing and replacement of bearings at regular interval. High temperature protection via PTC/PT100 is available. Wide adjustable speed range and high precision which lead to wider range of air capacity modulation. Compact size motor saves compressor foot print. Double layer housing with oil circulation that reduces noise level and realizes low vibration and stable operation. Very high efficiency: IE4 and IP65 protection class as options.
