Ingersoll Rand HLA2501H00AA Heatless 250cfm Desiccant Air Dryer, -40F F, 115v, HLA 250 47593675001

Ingersoll Rand HLA2501H00AA Heatless 250cfm Desiccant Air Dryer, -40F F, 115v, HLA 250 47593675001

The Ingersoll Rand HLA2501H00AA is a heatless desiccant air dryer rated to provide a steady -40ºF dew point. The HLA250 is rated to handle up to 250cfm from an air compressor. The dryer delivers an ISO Class 2 dew point to help prevent corrosion, minimize production disruptions and losses due to moisture or contamination. The dryer operates on 115v power.

HLA heatless desiccant air dryers are designed to increase reliability and efficiency for consistent delivery of clean, dry compressed air. Ingersoll Rands reliable, high strength, non-acidic desiccant provides maximum performance and is enironmentally friendly.

Ingersoll Rand’s HLA series of heatless desiccant dryers are designed to adsorb moisture from compressed air. The HLA250 dryer is constructed with two towers that alternate between online (drying) and offline (regenerating modes) in order to yield a continuous stream of dry air at the dryer’s outlet. Each tower contains desiccant beads. During normal operation, wet air passes through the online tower and water vapor from the air is adsorbed (collected) on the desiccant beads. While air is being adsorbed in the online tower, the moisture on the desiccant in the offline tower is removed by a process called desorption (regeneration). After an initial rapid depressurization, a portion of dried air from the online tower passes over the desiccant bed and carries the moisture off the bed and out the dryer’s exhaust.

A standard feature of every Ingersoll Rand heatless desiccant dryer is its NEMA 4 package, providing increased protection of electrical components, as well as advanced digital dryer controls and displays. It  includes a NEMA 4 electrical enclosure to protect against water and condensation, a UL/ULC panel and an advanced digital electronic controller. In addition, every HL comes standard with a compressor interlock feature. This substantially prolongs compressor life and improves reliability.

The HLA250 is rated to 250cfm. The complete model number is HLA2501H00AA and the internal Ingersoll Rand part number is 47593675001. The entire air dryer package operates on 110v/1ph/60hz power.

Ingersoll Rand Desiccant Dryer Controls

The advanced digital controller is programmed to execute all valve switching functions, as well as to completely monitor dryer operations. Further, it is MODBUS compatible permitting connection to MODBUS-capable networks and making some remarkable enhanced dryer operating functions. The controller’s full-featured panel includes:

• Backlit LCD display for viewing critical dryer parameters in all lighting conditions
• Integrated keypad, providing user with access to all internal functions and selectable displays
• Schematic depiction of dryer offering visual indication of current operating status
• Remote alarm contact
• Failure code storage
• Multiple displays, from “Dryer On/Off Control” to “Regeneration Sequence Status”

HLA2501H00AA : 250cfm Heatless Desiccant Air Dryers 

• Status Panel Display: In addition to the digital controller, a status panel display is also pre-installed. This provides an easy to understand indication of the air dryer status and a schematic diagram of the air dryer.
• Pre and Post Filtration Included: The HLA250 desiccant dryer includes a .01ppm pre-dryer filter to remove oil residue and dust particles prior to entering the dryer. A 1 micron general purpose dust filter is installed after the air dryer to prevent any desiccant dust from getting downstream.
• High-Performance Valves: With manifolds angled toward the center at the 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.
• Reduced Energy Use: Low pressure drop design saves on energy costs and provides an economical drying solution
• Reliable Operation: High-strength desiccant along with durable valves and components provide extended life
• Easy to Maintain: A low profile design and easy access to components simplifies installation and maintenance
• High Air Quality: High-performance desiccant technology delivers ISO Class 2 or Class 1 pressure dew point air for critical applications; high efficiency pre-filter and general Purpose after-filter protect desiccant and downstream air from oil contamination and particulates.
