Kenox Low-Pressure Air Dryer: Technical Overview

Product Overview

Kenox Air is a trusted manufacturer and exporter of Low-Pressure Air Dryers. These specialized refrigerated units are engineered to efficiently remove moisture from air generated by low-pressure industrial blowers and compressors. Our system uses a high-efficiency air-to-refrigerant heat exchanger to condense vapor into water, which is then reliably drained, safeguarding your assets from corrosion and contamination.

How Does the Low-Pressure Dryer Work?

The system employs a carefully calibrated refrigerated drying cycle. Hot incoming air is first pre-cooled in an air-to-air heat exchanger by the outgoing dry air. The subsequent air-to-refrigerant cooling stage forces moisture to condense into liquid form, which is safely expelled. This optimized process minimizes pressure losses inherent to low-pressure applications.

Specialized Features for Low-Pressure Performance
  • Low-Loss Heat Exchanger: Features specialized non-corrosive Copper/Shell heat exchanger design, engineered specifically to achieve lower pressure drop critical for maintaining blower efficiency.
  • High-Flow Separator: Contains an integrated Centrifugal Moisture Separator optimized for high-volume, low-pressure airflow, ensuring comprehensive condensate removal.
  • Intelligent Condensate Management: Equipped with an electronic (Digital) timer-operated Auto Drain Valve for precise, efficient, and reliable liquid discharge without manual intervention.
  • OZONE Friendly Refrigerants: All units are factory-filled with environmentally compliant, OZONE Friendly refrigerants (R-134a, R-410A, or R-407C) for global environmental standards adherence.
  • Variable Load Stability: Features a non-cyclic refrigeration system with hot gas bypass to maintain stable performance and optimal dew point control under varying flow or ambient conditions.
