ADEKOM OIL-FREE LOW PRESSURE BIOGAS SCREW COMPRESSOR

Product overview

Benefit from Adekom’s DryScrew OilFree Compressor technology—now optimized for biogas and RNG.

Adapted from our industrial air compressor line, the KDS series is engineered for 100% oil-free, Class 0 dry-screw compression—preserving biomethane purity in treatment plants, CHP systems, and grid injection setups.

With over 100 installations worldwide, the KDS compressor line is tailored to meet biogas-specific requirements:

100% oil-free compression chamber: Prevents oil carry-over into compressed gas, protecting downstream PSA, membranes, and upgrading equipment—crucial for RNG quality.
Class 0 certified (ISO8573-1): Ensures absolute purity—meeting the most stringent standards for biomethane processing.
Dry-screw mechanism: Offers steady, vibration-free performance with minimal maintenance, suitable for continuous 24/7 operation in biogas environments.

Product Features

High-Efficiency Explosion-Proof VSD Motor

Rated IP55 for superior protection and enhanced environmental adaptability.
Certified explosion-proof by CSA and UL standards.
Equipped with premium-efficiency motors from globally recognized brands such as WEG or TECO, ensuring high energy savings and reliable performance.

High-Efficiency Inlet Filtration System

The stainless steel inlet separator tank integrates inertial separation and a 5-micron inlet filter element to effectively remove liquid water and contaminants—greatly enhancing the reliability of the oil-free biogas gas-end.
Extended service life and longer maintenance intervals.
Automatic zero-loss condensate drainage system included.

Stainless Steel Discharge Silencer

Equipped with a stainless steel discharge silencer as standard, significantly reducing operating noise levels.
Compliant with ASME standards or CRN registered for safety and quality assurance.

Dry-type Oil-free Biogas Screw Gas-end

Utilizes a German-designed, dry-running, oil-free gasend whose next-generation rotors employ a parallel, asymmetric male-female configuration. The deeper helical grooves admit greater volumetric flow while substantially reducing internal leakage.
Both stainless steel rotor and housing exteriors are finished with a novel, high-temperature, oxidation- and corrosion-resistant super-coating that exhibits exceptional adhesion. This coating maintains peak compression efficiency under prolonged high-temperature, high-pressure operation, significantly extends gasend service life, and lowers lifecycle costs.
Precision-machined external timing gears ensure the male and female rotors run stably without contact, enabling minimal lobe clearance and markedly higher compression efficiency.
The gasend housing features a full-circumference cooling jacket adaptable for water- or oil-based cooling. This high-efficiency heat-exchange design supports tighter rotor-to-housing clearances and sustains optimal volumetric efficiency under varying load profiles.

Stainless Steel Biogas Cooler

Oversized heat exchange surface ensures minimal temperature rise and excellent cooling performance, with sufficient design margin to enhance overall system efficiency.
Corrosion-resistant and scale-resistant construction allows for sustained high-performance operation over extended periods.
