91 m³ DOT DROGON Dry Room for ENEA

‎ ‎ ‎

Il Disgelo designed for ENEA a custom 91 m³ DOT DROGON Dry Room, intended for research activities requiring extremely controlled humidity conditions.

The system operates between +23 °C and +25 °C, with a dew point down to −45 °C with two operators inside and down to −60 °C with the room empty.

‎

Developed Solution

The Dry Room integrates a highly insulated modular structure, a dedicated airlock for controlled access, resin-coated flooring acting as a vapour barrier, and air distribution through perforated ducts.

The solution also includes:

• usable volume of approximately 91 m³;
• dew point down to −60 °C;
• dedicated airlock;
• enthalpy drying system;
• pre-cooling and post-cooling;
• uniform air distribution;
• pressure and oxygen monitoring;
• emergency extraction;
• glove box for ultra-low dew point activities;
• control and supervision through CliMaLogic®;
• Ethernet, VNC Viewer and Modbus TCP/IP.

‎

Main Technical Data

• temperature: +23/+25 °C;
• temperature stability: ±1 °C;
• dew point with two operators: down to −45 °C;
• dew point with empty room: down to −60 °C;
• controlled area: approx. 26 m²;
• insulation: 100 mm expanded polyurethane;
• refrigerant: R449A;
• compressor: semi-hermetic;
• air distribution: perforated ducts;
• control: CliMaLogic®;
• programming: up to 500 programs with 20 steps each;
• connectivity: Ethernet, VNC Viewer and Modbus TCP/IP.

Result

The project enables ENEA to carry out experimental activities in a large-scale environment with an extremely low dew point, while maintaining controlled conditions even with operators inside.

The integration of an airlock, vapour barrier, perforated air distribution and glove box makes the Dry Room suitable for handling materials and components particularly sensitive to humidity.
