15 m³ Walk-In Chamber for Lear Engineering Italy

‎ ‎

Il Disgelo designed and built for Lear Engineering Italy a custom 15 m³ Walk-In climatic chamber, developed for thermal-climatic testing of automotive components and systems.

The system operates between −40 °C and +120 °C, with humidity control and temperature change rates up to 3 °C/min, according to the conditions required by the PV 1200 Test Cycle.

‎

Developed Solution

The chamber features an insulated structure with an AISI 304 stainless-steel interior, reinforced floor and double-leaf door with a heated inspection window.

For the required test conditions, the system integrates an upgraded refrigeration unit and an additional dry-air system.

The solution includes:

• usable volume of approximately 15 m³;
• −40/+120 °C temperature range;
• 20–90% RH humidity;
• temperature change rates up to 3 °C/min;
• DUT mass up to approximately 400 kg;
• configuration for the PV 1200 Test Cycle;
• floor load up to 1000 kg/m²;
• additional drying system down to −40 °C dew point;
• remote condenser;
• CliMaLogic® control;
• Ethernet, VNC Viewer and Modbus TCP/IP.
