Italian CLIMATIC CHAMBER
Climatic chamber designed for thermal and climatic testing of integratede-Axle systems and motor-transmission assemblies, developed for high-precision automotive applications and direct integration with dynamometer test benches.
The platform is available in two configurations:
2.9 m³– standard configuration for functional and durability testing
4.0 m³ with Z-axis– version with integrated vertical movement system for enhanced operational flexibility
Both configurations share the same structural architecture, refrigeration concept and DOT control platform.

Structural Architecture
Welded internal structure in AISI 304 stainless steel
Coupled twin half-shell configuration
Total insulation thickness: 150 mm high-density mineral wool
Double perimeter sealing system for thermal continuity
Reinforced insulated floor with stainless steel profiles
Nickel-plated FE510 steel base plate(50 mm thickness) for torque discharge
Prepared for anchoring to seismic mass foundation
In the4.0 m³version, the chamber integrates:
Vertical movement system (Z-axis)
Three shaft feedthroughs per side for vertical kinematic management
The architecture enables fast installation and alignment of complete e-Axle systems.
