Product Features
Rapid temperature transition performance
Capable of transitioning from +20°C to -70°C in about 25 minutes and from +20°C to +180°C in about 33 minutes. Rapid temperature change is realized assuming compensating load.
Wide temperature and humidity test range
Temperature range is -70°C to +180°C, humidity range is +10°C to +95°C, 10 to 95%RH. A unique humidity control system enables long-time frost-free operation, and can be controlled up to 10°C/10%RH as an option.
Allowable heat generation load
It can handle a maximum of 5 kW in the -20°C to +100°C range and a heat-generating load of 500 W in the +25°C to +95°C/-90%RH condition.
greennmode® for energy savings of up to 40%
The greennmode® comes standard, and the heating and cooling system operates efficiently. It reduces power consumption by up to 40%, contributing to lower testing costs.
Space-saving design
Cooling equipment is placed at the top and major components made by domestic manufacturers are used. Compact design for easy installation even in a limited testing room.
operability
- Unique inner tank structureEasy to clean due to: special welding, smooth surfaces, and rounded edges.
- Double ceiling structurePrevents condensation in the ceiling area.
- Left and right measurement holesStandard: Right Φ125 and left Φ50 measuring holes.
- Simple wick exchange systemWick: Wick is laid out in the lower front part of the tank. The front door can be opened for easy access for easy replacement. In addition, the unique water supply mechanism reduces the frequency of replacement.
- Large observation windowThe largest area in its class (W420 x H570mm). Unique four-tank glass structure for outstanding visibility.
- Touch panel "WEBSeason®"Color TFT touch display with Japanese display and intuitive interface. Intuitive operation for both advanced program settings and data analysis. Multi-user functionality allows assignment of user privileges and simultaneous access, as well as remote access from PCs, smartphones, and tablets. Test results can be downloaded in CSV format.
Environmentally Friendly
- Low GWP refrigerantNew refrigerant R-469A: GWP value of 1357 is more than 90% less than R-23 and more than 75% less than R-508A, significantly reducing the burden on the global environment.
- Regulatory complianceF-gas regulation compliant and can meet future environmental standards.
