Custom DOT DROGON Walk-In Climatic Chamber for VDE Fabriano

‎

Il Disgelo designed and manufactured for VDE Global Service – Fabriano site a custom DOT DROGON Walk-In climatic chamber with a usable volume of over 21 m³, developed for environmental testing under controlled temperature and humidity conditions.

The chamber was configured to provide stable and repeatable climatic conditions, integrating dedicated air-treatment, refrigeration, heating, humidification, dehumidification and automatic control systems.

‎

Developed Solution

The configuration uses a modular prefabricated structure with an AISI 304 stainless-steel interior, high-density polyurethane insulation and a ceiling-mounted air-treatment system.

The system was designed to provide:

• combined temperature and relative humidity control;
• thermal variation rates up to 1 °C/min in heating and cooling;
• uniform air distribution inside the test chamber;
• continuous operation for environmental testing;
• programmable management of test cycles;
• recording and export of test parameters;
• remote supervision via Ethernet network;
• easy chamber access thanks to the threshold-free entrance;
• independent safety and thermal protection systems.

Control is managed by the CliMaLogic® system, with PLC and touch panel, climatic program management, alarms, data logging and communication with external systems via VNC Viewer and Modbus TCP/IP.
