Type 3 Composite Pressure Vessels
Pressura manufactures Type 3 pressure vessels with metal liners and composite reinforcement for safe and efficient storage and transportation of high-pressure gases.
Designed for CNG, hydrogen and cryogenic gas applications, these vessels are developed to meet relevant standards and customer requirements, with a focus on high mechanical strength, low weight and long service life.
Design, material selection, manufacturing and testing are carried out as an integrated process using Pressura’s engineering capabilities.
- A wide volume range from 3 L to 375 L.
- Composite pressure vessels up to 600 mm in diameter and 3,750 mm in length.
- Winding capability with carbon, glass, aramid and other fibres.
Type 4 Composite Pressure Vessels
Pressura specialises in the design and manufacture of Type 4 composite pressure vessels, particularly for CNG and hydrogen applications. Combining a polymer liner with a high-strength composite structure, these vessels offer a 75% weight advantage over conventional metal tanks and provide reliable, long-lasting storage under high pressure.
Vessel solutions for trucks, buses, tractors, construction equipment, marine vessels and light commercial vehicles are developed for each customer, taking capacity, pressure, geometric constraints and operating conditions into account. Pressura Type 4 CNG vessels hold UN ECE R110 type approval certification.
- Type 4 composite pressure vessels up to 375 L with a diameter of Ø402 mm under ECE R110.
- A wide volume range from 3 L to 375 L.
- Composite pressure vessels up to 600 mm in diameter and 3,750 mm in length.
- Winding capability with carbon, glass, aramid and other fibres.
Composite Sleeves and Tubes
Pressura manufactures composite sleeves and tubes for a variety of industrial applications. Produced using filament winding, these structures offer a high strength-to-weight ratio, corrosion resistance and application-specific design options.
Solutions in different diameters, lengths, winding angles and material combinations are developed for pressure systems, structural applications and specialised engineering needs.
- Maximum winding diameter of 600 mm.
- Dual-spindle winding capability.
- Winding length of 3,750 mm.
- Automatic resin dosing system.
- Winding capability with carbon, glass, aramid and other fibres.
Custom Composite Parts
In addition to pressure vessels, Pressura develops custom composite parts for different industries. Using carbon fibre, glass fibre and suitable resin systems, we provide tailored solutions for applications requiring high strength, low weight, corrosion resistance and functional performance.
Pressura’s engineering team manages design, prototyping and the transition to serial production, taking the intended use, loading conditions, environmental conditions and manufacturing requirements into account.
Testing Services
Pressura offers comprehensive hydrostatic and pneumatic validation testing to verify product performance and reliability. Proof testing, torque measurement, burst pressure testing, cycle life testing and gas leak testing are carried out in accordance with relevant standards, technical specifications and customer requirements.
Our test infrastructure supports product development and validation, providing engineering solutions for the testing needs of both Pressura products and other pressure vessels and composite structures.
