    The research and development are an important component of PNEUMOIDRAULICA ENGINEERING activity. Our technical department is constantly active to improve existing products, according to the continuous technological and standards changes and to create new products based on the market demands.

    We are specialized in the design and production of “custom-made” components (pneumatic or hydraulic operated) with highest quality and reliability levels.

    Our innovative 3D printer allows us to realize all the prototypes extremely rapidly at a very low cost. We also realize exclusive products with the customer logo.

    Our strength?

    Provide control systems with a quality and reliability at the highest levels on the market!

    Innovation, spirit of enterprise and technical challenges were the main elements that characterized the birth, in 1994, of PNEUMOIDRAULICA ENGINEERING. The goal, to provide high quality products for Oil & Gas.

    Still today PNEUMOIDRAULICA ENGINEERING is on the market not as a dealer but as a designer, manufacturer, installer and provider of maintenance of pneumatic and hydraulic control and safety systems.

    Our long experience in the field, thanks to the multi-year service activity (both on-shore and off-shore) and the plants direction, assures us a precise and continuous training, essential for the design of new plants. PNEUMOIDRAULICA ENGINEERING is authorized as a “Metric Operator” for the calibration and the repair of the fiscal measuring equipment.


    Constantly achieve the highest quality in order to supply our customers with high quality and reliability products at a competitive price giving an excellent technical assistance and consultant services differentiating ourselves from the competitors.

    Raise awareness among our potential customers. If they invest in the high quality of our product they have an initial cost which it will be extensively recovered thanks to the absence of anomalies and shutdowns.

    Core values:

    • Safety at work with respect for people and the environment
    • Integrity and Transparency
    • Time and Cost efficiency
    • Flexibility, Creativity and Innovation
    • Supply products and services of optimal quality

  • Gas sampling systems
    PNEUMOIDRAULICA ENGINEERING designs and manufactures "tailor made" gas sampling systems...

  • The sampling system, through a suction circuit, picks up the gas to be analyzed and it takes it, after appropriate treatment, to the analysis tool that verifies its features.


    The most common application is to monitor an explosive mixture or toxic gases inside a zone: at exceeding the set threshold, the system generates an alarm that immediately provides safety for facility, avoiding damage to people and environment. For particular critical applications, the system provides 3 points of analysis, in 2oo3 logic.
