- Energy efficiency
Incorporates DC inverter technology that enables true automatic capacity adjustment based on system demand.
At minimum load, it consumes only about 20% of the power compared to conventional fixed-speed dryers, allowing operators to significantly reduce electricity costs—often enough to recoup the equipment investment within a year. - High performance
Enhanced by an aluminum alloy three-in-one plate heat exchanger working in concert with variable speed technology.
Provides precise and responsive dew point control, maintaining optimal air quality even under dynamic load conditions. - Intelligent operation
Automatically adjusts compressor frequency in response to changing operating conditions.
Features a comprehensive self-diagnostic system with a user-friendly interface that clearly displays operational status and alerts for optimal maintenance and reliability. - Environmentally friendly
Uses R134a and R410A refrigerants compliant with the Montreal Protocol, ensuring zero ozone depletion potential and full alignment with international environmental standards.
- Stable performance
The variable speed system extends the dryer’s operating temperature range, maintaining full-capacity output under high-temperature conditions to ensure rapid dew point stabilization.
Under extremely low ambient temperatures, it reduces output frequency to prevent freeze-ups, while continuing to maintain consistent dew point control.
