This combined compressed air dryer integrates refrigerant and adsorption drying stages into a single unit, designed to achieve a low dew point for sensitive industrial processes. The source confirms a working pressure range of 0.6 to 1.0 Mpa and a pressure drop under 0.05 Mpa. Inlet temperature is maintained for optimal performance, but no maximum inlet temperature is specified.
Typical combined dryers use refrigerant cooling to reduce air temperature to 2°C to 5°C, followed by a desiccant bed (often silica gel or molecular sieve) to achieve dew points as low as -40°C. The unit likely includes automatic drain valves, pressure gauges, and a control panel. Standard inlet air temperature is 35°C to 45°C; exceeding this reduces efficiency. The supplier does not disclose dryer capacity in CFM or m³/h.
These dryers serve industries requiring clean, dry air: pharmaceutical manufacturing, food packaging, electronics assembly, and precision tooling. Buyers include plant engineers and maintenance managers responsible for compressed air system reliability. Trade terms include FOB and CIF shipping, with payment via L/C or T/T. MOQ is described as flexible but unquantified; buyers must confirm unit availability and delivery schedule directly.

Before ordering, confirm the exact dew point specification under full load, the type of desiccant used, and the regeneration method. Request a performance curve showing pressure drop versus airflow. Do not accept vague claims of 'high efficiency' without test data. Verify the refrigerant type for environmental compliance in your region.
Shipping is offered under FOB or CIF terms, but origin port and delivery time are not stated. Confirm the Incoterm version, estimated lead time from order confirmation, and packaging method (crated, palletized). Payment terms are L/C or T/T; request a proforma invoice with full technical specs and HS code before payment.
On delivery, inspect for shipping damage, correct labeling, and matching serial numbers. Test the dryer under load using a dew point meter to verify performance. Request a certificate of conformity with test dates, pressure settings, and desiccant batch traceability. Retain samples of desiccant for future replacement verification.
