Refrigerated compressed air dryer with an adjustable pressure dew point. The Compressed Air Dryer is built for continuous industrial duty. It runs on a direct-coupled air end with no belts to re-tension, and it is delivered as a complete package — airend, motor, cooler, separator and controller on one base frame — so on-site work is limited to power, piping and a drain.
A single cutaway view of the whole unit: airend, drive motor, separator tank, coolers, filtration and controller mounted on one base frame. Use it to check the space envelope and service access before ordering.
A single-stage oil-injected rotary screw airend with asymmetric rotors machined and lapped as a matched pair. Large-diameter rotors run at low speed for a long bearing life and a stable specific power figure.

Aluminium plate-fin coolers for the oil and the compressed air, with a fan sized for ambient conditions. Keeps discharge temperature inside the limits that protect the oil charge.

Drying the air between the receiver and the point of use.
Protecting instruments from condensate.
Preventing water carry-over into tools and cylinders.
Dry air for a clean finish.
Dry air where moisture would affect the product.
Every unit ships with an 18-month warranty on the air end and 12 months on the rest of the machine, counted from commissioning or 24 months from shipment, whichever comes first.
Each machine is run on the test bench and the delivered flow, working pressure, current draw and noise level are recorded against the datasheet before it is crated.
Installation drawings, piping diagrams and a commissioning checklist are supplied with the machine, with remote engineering support during start-up.
Airends, motors, controllers, filters, separators and cooler assemblies are held in our own warehouse, so service parts are not tied to a production run.
If condensate can reach the tools or the product, yes. Compressed air leaves the receiver saturated, and it cools on the way to the point of use — the water has to come out somewhere.
The pressure dew point is in the specification table. A refrigerated dryer suits general workshop and process use; for instrument air you would go to a desiccant dryer.
The unit is fitted with an automatic drain on the condensate outlet. A blocked or manual drain is the most common reason a dryer appears not to be working.
Downstream of the receiver in a ventilated position, with enough clearance for the condenser airflow and for servicing the refrigeration circuit.
