1617505173 (=1617505128): ROTOR DRYER

The Atlas Copco 1617505173 (=1617505128) Rotor Dryer stands as a precision-engineered core component designed specifically for Atlas Copco MD series rotary drum adsorption dryers. This genuine rotor, which supersedes the old part number 1617505128, plays a critical role in maintaining the superior drying performance that Atlas Copco’s MD air dryers are renowned for worldwide.

Product Introduction

Atlas Copco’s MD series rotary drum dryers utilize advanced heat-of-compression technology to deliver cost-effective, dry, and oil-free compressed air. The rotor dryer sits at the heart of this system—it houses the desiccant material that actively adsorbs moisture from the compressed air stream, ensuring that downstream equipment and processes receive only the highest quality dry air. Unlike traditional twin-tower desiccant dryers that waste significant amounts of compressed air through purge cycles, the MD series rotary drum dryers feature a zero-purge design that eliminates this waste entirely.

We supply this product as a 100% genuine new original part, sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. We do offer only authentic Atlas Copco components that meet the manufacturer’s exacting standards for quality, durability, and performance.

Why Choose the Atlas Copco Rotor Dryer?

1. Zero Purge Design – Maximum Energy Efficiency
The MD series rotary drum dryers eliminate the waste of compressed air associated with twin tower dryers. Traditional desiccant air dryers consume a portion of the compressed air they produce simply to regenerate the desiccant material—this is known as “purge air” and can represent a significant operational cost. The Atlas Copco rotor dryer, however, operates with zero purge, meaning 100% of your compressed air capacity remains available for production. The only energy consumption comes from the drum motor and controls, resulting in the lowest energy consumption dryer in the market.

2. Superior Moisture Removal
The rotor dryer achieves consistently low pressure dew points, ensuring that your compressed air system delivers dry air even under fluctuating load conditions. For MD series dryers, this means achieving pressure dew points as low as -25°C (-13°F). This level of dryness protects your pneumatic tools, instrumentation, and end products from corrosion, contamination, and moisture-related failures.

3. Swedish Engineering – Built to Last
Manufactured in Sweden, this rotor dryer undergoes rigorous testing to maintain Atlas Copco’s world-class standards for durability, balance, and performance stability. Premium materials and advanced coating technology provide superior corrosion resistance, extending the service interval significantly.

4. No Pre-Filters or After-Filters Required
MD and ND rotary drum dryers need no pre-filters, no after-filters, and no dust filters—all of which can cause pressure drops and increase maintenance costs. This simplified design reduces both capital expenditure and ongoing operational expenses.

5. Compact Footprint
The rotary drum design creates a compact, space-saving footprint, especially when compared to oil-lubricated systems that require extensive filtration. This makes the rotor dryer an ideal choice for facilities where floor space is at a premium.

6. Ideal for Critical Industries
Atlas Copco rotary drum dryers deliver dry, oil-free air that meets the stringent requirements of food and beverage production, power generation, pharmaceutical manufacturing, automotive assembly, breweries, and pulp and paper processing.

Installation Steps

Installing the Atlas Copco Rotor Dryer (1617505173) requires careful attention to procedure. Follow these steps for a successful installation:

Step 1: Preparation and Safety

• Depressurize the MD dryer system completely and disconnect all pressure sources.
• Ensure the work area is clean and free from contaminants that could compromise the new rotor.
• Gather all necessary tools and refer to the MD series instruction manual for specific torque specifications.

Step 2: Remove the Old Rotor

• Open the dryer housing access panel following the manufacturer’s guidelines.
• Carefully disconnect any wiring or sensors attached to the existing rotor assembly.
• Remove the retaining hardware and gently extract the old rotor from the drum housing.
• Inspect the housing interior for any debris or wear that may require attention before installing the new unit.

Step 3: Prepare the New Rotor

• Unpack the new rotor dryer (1617505173) from its protective packaging.
• Inspect the rotor for any signs of shipping damage—verify that all surfaces are clean and intact.
• Confirm that the part number matches your requirements (1617505173 replaces the older 1617505128).

Step 4: Install the New Rotor

• Position the new rotor carefully into the drum housing, ensuring proper alignment with the drive mechanism.
• Secure the rotor using the specified hardware and torque settings.
• Reconnect any wiring, sensors, or control connections that were disconnected during removal.

Step 5: Close and Test

• Replace the housing access panel and secure all fasteners.
• Restore pressure to the system gradually, checking for any leaks around the housing.
• Power on the dryer and monitor the Elektronikon® controller for proper operation.
• Verify that the dryer achieves the expected pressure dew point and that all parameters read within normal ranges.

Note: Installation is straightforward, as Atlas Copco designs the rotor for direct, drop-in replacement with 100% dimensional compatibility. However, we always recommend that installation be performed by qualified technicians familiar with Atlas Copco MD series dryers.
