Product features

Support standard modular customization.

With the aim of shortening equipment lead times and reducing design and engineering costs associated with generic custom walk-ins without compromising equipment quality and reliability, KOMEG introduces modular custom design solutions.

◎ Laboratory warehouse board: high-density foamed thermal insulation color steel plate, which can meet multiple assembly and disassembly operations, and strengthen the bottom plate to reach a load of 3000kg/m².

◎ Refrigeration System: Contains the cooling unit and humidification system required to control the temperature and humidity in the walk-in room.

◎ Ventilation system: The powerful fan absorbs heat from the air in the test room for cooling and dehumidification, and the temperature is more uniform.

◎ Control system: KOMEG independently developed TT-5166 programmable 7" color touch screen controller, which has the characteristics of automatic, intelligent and humanized control.
