Reciprocating compressors for hydrogen

SIAD Macchine Impianti’s hydrogen compressors are reciprocating compressors which can compress hydrogen or hydrogen-rich mixtures for all types of applications, with any degree of purity.

We have a proven track record in this sector, with thousands of hydrogen compressors installed throughout the world. 

H2 testing facility: we test our products in-house

SIAD MI boasts an in-depth knowledge of gases and related processes, since the parent company, SIAD S.p.A., is a Gas Company. The SIAD Group already has a hydrogen production unit operating for many years at the Osio plant.
Right in front of the existing hydrogen production unit, SIAD MI has created a testing facility where their own test compressor will be installed. In this way SIAD MI can have all the hydrogen they need in-house, to carry out all the necessary compressor tests.

Designed and built in accordance with the ATEX Directive 94/9 / EC, or other applicable standards (including: API standard 618; SAE standard J2601 and J2719) our hydrogen compressors present the following characteristics:

 

  • Fitted with rod seal packs with a gas recovery system from packing rings to avoid loss of H2 and rods specially treated to work at high pressure in no-lube conditions;

  • Flushing of the spacer chambers and frame with inert gas (nitrogen);

  • Zero-leakage connections with metallic ring join gaskets (1500# and 2500#) and dedicated metal-to-metal sealing above 2500#;

  • Specific design and selection of materials for valves (low lift, high quality PEEK grade for plates);

  • Specially designed piston rings, rider rings and rod packing rings, either for materials and for geometry;

  • Rugged cylinder design in forged steel for higher pressure values;

  • Wide and generous cooling area to keep sliding surfaces at low temperature and extend rings’ lifetime;

  • Water cooled rod packing.

Thanks to its engineering services, SIAD Macchine Impianti is able to produce reciprocating compressors that integrate perfectly in the existing production lines:

  • Pulsation, acoustical, torsional, bending analysis;
  • Finite elements structural verification;
  • Fluid-dynamic verification Fatigue calculation;
  • Measurement and verification of vibration, ultrasonic, thermography, radiography;
  • Chemical, physical and metal particles oil analysis.

 

Software for Mechanical calculation 
3D modelling, static elastic Fem analysis, infinite life fatigue analysis 
Elastic bodies motion of the complete frame, static elasto-plastic Fem analysis
Multiaxial fatigue analysis with the algorithm of Dang Van or Brown – Miller – Morrow

Computational Fluid Dynamics (CFD) Software
The gas paths are studied by the computer with most advanced CFD software with the aim to reach at the same time a small clearance volume, for a greater volumetric efficiency, and large and well profiled passages for low pressure losses.

Digital instrumentation (3D, 6axis measurements) & Augmented Reality tools
Capable of detecting the measurements of some components our compressors comparing them with those of the technical drawings. In this way, we are able to create real "digital twins” of our machines and to evaluate their performance, developing, where necessary, improvement actions to offer our customers increasingly reliable and top performing products.
