Even easier to use. The COLONIA E series walk-in chamber is now available, featuring the low GWP refrigerant R-448A (GWP value: 1387) for a new era.

The new COLONIA E Series uses the new refrigerant R-448A with a GWP value of 1387, far exceeding the 2025 GWP target of 1500 or less. While maintaining the same high performance as before, operability and functionality have been significantly improved. COLONIA's innovative spirit is one step ahead of the times.

The wide temperature and humidity range allows reliability testing under various temperature and humidity conditions, from high temperature and humidity to low temperature.The non-frost range can also be expanded (optional).Continuous operation is possible even in low temperature and low humidity ranges without defrosting the cooling coil.

New controller that makes reliability testing safe, convenient, and hassle-free

The adoption of a 7.5-inch wide color LCD has further improved operability and visibility, making the ETACOM even easier to use and more comfortable to operate. With a sophisticated interface, all operations are controlled by the ETACOM touch panel.

Easy-to-read interior status display panel

The highly visible display panel displays three statuses - [TROUBLE], [RUN], and [ENTERING/EXITING] - to make it easy to understand the operating status. It can be installed on either the left or right side of the door, allowing you to check the status of the room at a glance.

Secure effective space in the testing room

By flattening the air conditioning unit in the testing room, protrusions on the walls are eliminated, ensuring effective space within the testing room. This does not interfere with sample placement or setting, allowing for more spacious use of the testing room.
