Adsorption

When we designed the Ingersoll Rand heatless, heated and heated blower desiccant dryers we set our sights on creating the most reliable desiccant dryers you can purchase and operate. And our success was extraordinary. We set a new standard, and, in fact, re-wrote the book.

One look tells you that these dryers are like no others…extremely low silhouette… manifolds and valves within an arm’s reach of the operator…readily accessible fill and drain ports…just a few of the differences apparent on the outside.

Easy to maintain / high performance valves

With manifolds angled toward the center at operator level, the valves are easily accessed for maintenance. A typical diaphragm valve in a heatless dryer can be rebuilt in less than ten minutes, without removing the valve from the manifold.

Ingersoll Rand HL Heatless Desiccant Dryer

While reliability has been a key focus of its design, the Ingersoll Rand HL heatless desiccant dryer is also a leader in its class for energy efficiency and the health and safety of operating personnel and the environment.

• Designed to ensure a constant –40°F (-40°C) or optionally –100°F (-70°C) pressure dew point, virtually eliminating costly interruption of production due to moisture

• Estrategic pre-filter and after-filter

• Switching valves are normally open and purge valves normally closed, to allow air flow through the dryer in case of power loss.

• NEMA 4 package: electrical enclosure to protect against water and condensation; advanced digital electronic controller; compressor interlock feature

Ingersoll Rand HB Heated Blower Desiccant Dryers

Ingersoll Rand HB heated blower desiccant dryers are equipped with dedicated durable centrifugal blowers to provide purge air for regeneration, eliminating the need to divert dry compressed air from the air system. Instead, the blower directs ambient air through an external heater and then through the off-line tower to regenerate the desiccant. This means more compressed air is available for critical downstream applications.

• DAvailable in sizes from 1000 SCFM (28.3 nm3/min.) to 8000 SCFM (226.5 nm3/min.), Ingersoll Rand HB dryers deliver –40°F (-40°C) pressure dew point air.
• HB heated blower models provide the reliability and safety features of heatless dryers, with increased energy efficiency. These features include heatless backup mode in the event of heater or blower malfunction, and an innovative solid-state relay heater control to extend valve and heater life. NEMA 4 electrical enclosures are standard and include an advanced multi-function digital controller.
