Desiccant Air Dryer HRBS-110AGR 11m³/min -40°C Dew Point Activated Alumina

The HIROSS AIR HRBS-110AGR is a twin-tower desiccant air dryer rated at 11 m³/min with a pressure dew point of -20 to -40 °C, for applications where refrigerated drying is not dry enough. Two stainless steel towers (A and B) hold activated alumina and molecular sieve media that are regenerated in service instead of being replaced on every service interval. Inlet air is limited to 40 °C. An integrated cabinet with an LCD touchscreen carries the control and operating status. The unit stands on a stainless steel skid base, with a tagged valve manifold for clear maintenance.

1. Pressure dew point of -20 to -40 °C The dryer reaches dew points well beyond the range of a refrigerated dryer, so air stays dry even in long outdoor lines, in cold climates and in processes that cannot tolerate condensed moisture at the point of use.

2. Twin-tower design for continuous drying Two towers (A and B) work in sequence: while one dries the air stream, the other is regenerated. Drying continues through the changeover, so the downstream process does not see a wet-air interval during regeneration.

3. Activated alumina and molecular sieve media The two desiccants are combined in one unit: activated alumina takes the bulk of the moisture, and molecular sieve polishes the air to the final dew point. Media are regenerated in service rather than being replaced on every service visit.

4. Insulated stainless steel towers The towers are built from stainless steel and covered with an insulation jacket. Stainless steel resists corrosion from wet air and condensate, and the insulation holds the heat used in regeneration, which is where a desiccant dryer loses efficiency if the tower surface is left bare.

5. LCD touchscreen control in an integrated cabinet The control cabinet carries an LCD touchscreen together with three push buttons including the emergency stop, and the door lock keeps settings out of reach of unauthorised hands. Operating status is read at the panel rather than from separate indicators on the skid.

6. Tagged valve manifold The valve manifold is fitted with number tags (K and V codes) that match the piping and instrumentation diagram. During commissioning or a fault, the engineer identifies the valve from the tag instead of tracing pipework, which shortens service time. Spare valves can also be ordered against the same tag numbers, so a replacement part matches the position it came from.

7. Aluminium piping and flanged joints The piping is aluminium with bolted flanged connections, keeping the assembly light and making joint replacement straightforward on site.

8. Skid-mounted, factory-assembled base frame Towers, valves, piping and the control cabinet are assembled on one stainless steel base frame. The unit arrives as a single package with a single lifting point, so site work is limited to connecting air, condensate and power.

9. Rated for 11 m³/min with inlet air up to 40 °C The 11 m³/min capacity suits mid-size plant air systems. Because the inlet limit is 40 °C, the specification makes clear that a refrigerated dryer or aftercooler is normally installed ahead of the unit.
