Blower Regenerative Desiccant Air Dryer HRS-550GRD 55m³/min -45°C Dew Point

The HIROSS AIR HRS-550GRD is a blower regenerative desiccant air dryer rated at 55 m³/min, with a maximum working pressure of 0.7–1.0 MPa and a pressure dew point of ≤ -45 °C. Regeneration uses ambient air moved by the dryer's own blower, so regeneration air consumption is 0% and no dried compressed air is lost to purge. Insulated stainless steel towers and flanged piping are mounted on a fabricated steel skid, with a PLC and touchscreen cabinet for start, stop and monitoring. It suits large instrument-air and process-air systems in food, pharmaceutical, chemical, electronics and PET blowing plants.

1. Zero regeneration air consumption Regeneration air comes from ambient air moved by the machine's own blower, so regeneration air consumption is 0%. Unlike heatless (purge) dryers, which divert part of the dried compressed air to regenerate the desiccant, the HRS-550GRD does not take air away from production: the full output of the compressor reaches the plant.

2. Pressure dew point of ≤ -45 °C A -45 °C rated pressure dew point keeps moisture out of instrument air, pneumatic valves and long outdoor pipe runs. Condensation in the line — the usual cause of corrosion, frozen actuators and contaminated end products — is avoided at the design condition, which makes the unit suitable for critical process air rather than general plant air only.

3. Sized for high-flow plants The 55 m³/min rated air capacity at a maximum working pressure of 0.7–1.0 MPa matches large compressor rooms: where a plant runs several big compressors on a common header, one unit handles the full flow instead of several small dryers in parallel. One dryer therefore replaces a bank of smaller units, which reduces the number of drain points, filter elements and control panels to maintain.

4. Insulated stainless steel tower and flanged piping The desiccant tower is insulated and made of stainless steel, with flanged aluminium piping and flexible stainless connectors. Insulation reduces heat loss during regeneration, stainless steel resists corrosion at the tower, and flanged joints let pipework and valves be serviced without cutting the line.

5. PLC with touchscreen cabinet The control cabinet carries the HMI screen, start/stop buttons and emergency stop on one panel. Operating status and parameters are read from the screen, so the shift operator can check the dryer without opening the panel. The start/stop push buttons and the emergency stop sit within reach on the same face, so routine operation is handled from one position, and the model code and website are printed on the cabinet for identification.

6. Skid-mounted, factory-assembled design The complete dryer — towers, blower, valves, piping and control cabinet — is assembled on one fabricated steel base frame. Site work is reduced to positioning the skid, connecting inlet and outlet flanges and the power supply, so commissioning is faster and the pipework layout is fixed at the factory.

7. Rated for hot plant environments The specification includes ambient temperature ≤ 40 °C and inlet air temperature ≤ 45 °C as rating conditions. Those figures also set the upstream requirement: where inlet air arrives hotter than 45 °C, an aftercooler or additional cooling is needed before the dryer.
