Large Autoclaves
Φ3,500–4,200 mm aerospace-scale systems with redundant, standards-compliant control.
Overview
For large primary structures – fuselage panels, wing skins and major tooling – YRPR large autoclaves combine working diameters up to 4,200 mm with redundant, standards-compliant control. Dual-duty vacuum pumping with standby capacity, smart instrument logic and floor-standing operator consoles keep production running through component failure or maintenance events.
Where parts are too large even for this family, our super-large programme provides up to Φ10 m vessels – including complete on-site fabrication. See Super-Large Autoclaves or our manufacturing page.
Key Features
- Redundant host PC + PLC + smart instrument control architecture
- Vacuum pumps configured 2 duty + 1 standby for availability
- 750 kW minimum installed power for fast, uniform cycles
- Electric or thermal-oil heating with water cooling
- Nitrogen pressurisation option for oxidising-sensitive cure stocks
- Full AMS2750F-aligned instrumentation configuration
