- Energy efficiency
Utilizes flexible variable frequency technology, enabling precise adjustment of compressor speed according to system demand.
At minimum load, power consumption is reduced to about 30% compared to conventional fixed-speed dryers, allowing substantial electricity savings, often enough to offset the equipment cost within one 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 R407C refrigerant compliant with the Montreal Protocol, with zero ozone depletion potential, fully meeting global environmental requirements.
- 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.
