SCHULZ Refrigerated Air Dryer for 10HP & 15HP Compressors
This 50 CFM SCHULZ non-cycling refrigerated air dryer operates on 115V single phase power and supports compressors rated at 10HP and 15HP. Essential for optimal performance, a minimum 1-micron filter and water separator are required ahead of the unit, ensuring moisture and oil are effectively removed before air reaches the dryer. Buyers can opt for the “with pre-filter” package that provides both the dryer and a stage 1 water separator plus a stage 2 coalescing filter for oil removal. This combination makes it a comprehensive system for moisture and oil-free compressed air, perfect for standard industrial setups.
SCHULZ Refrigerated Air Dryer 35 CFM with Pre-Filter
This 35 CFM SCHULZ refrigerated air dryer includes industrial-rated water separator and oil removing coalescing filter as part of its complete package, eliminating the need for additional purchases. It suits air compressors rated 7.5HP to 10HP with a working pressure of up to 200 PSI, and its dew point is maintained at 41 degrees Fahrenheit for effective moisture reduction. The non-cycling design optimizes continuous performance. It also offers an option to include a regulator pre-filter, ideal for users requiring control over air pressure and filtration efficiency.
Ingersoll-Rand Refrigerated Air Dryer Type D12IN 7 SCFM
The Ingersoll-Rand D12IN refrigerated air dryer offers a 7 SCFM capacity and incorporates advanced features such as efficient heat exchangers and a stainless steel demister to achieve steady moisture removal. A fully adjustable programmable electronic drain valve minimizes compressed air loss and energy consumption. Its corrosion-resistant heat exchangers and enhanced control system deliver reliability for extended equipment life. Ideal for smaller compressors, its smart microprocessor control makes system management user-friendly and precise.
SCHULZ Refrigerated Air Dryer 75 CFM with Regulator Pre-Filter
This 75 CFM SCHULZ refrigerated air dryer is designed for heavy-duty compressors such as 15HP to 20HP units. It comes with an industrial-grade air pressure regulator, water separator filter, and coalescing oil filter, providing a complete drying and filtration setup. Operating up to 200 PSI with a dew point consistently at 41 degrees Fahrenheit, it delivers ultra-dry, clean air. The 1″ female NPT inlet and outlet ensure compatibility with standard compressed air piping. Users should confirm their compressor output does not exceed 175 PSI to safeguard the filters’ integrity.
Ingersoll-Rand Refrigerated Air Dryer Type D25IN 15 SCFM
The Ingersoll-Rand Type D25IN is a 15 SCFM refrigerated air dryer suitable for mid-range air compressors. It features an energy-efficient design with robust corrosion-resistant heat exchangers. Its built-in stainless steel demister aids in effective moisture separation, complemented by a programmable electronic drain valve that reduces air wastage. Operator convenience is enhanced with advanced microprocessor controls allowing easy parameter adjustments. This model emphasizes reliability and efficiency for consistent, dry air supply in commercial and light industrial environments.
Buying Guide for Refrigerated Air Dryers for Air Compressors
When selecting the best refrigerated air dryer for your air compressor, consider the following critical factors:
- Capacity (CFM): Ensure the dryer capacity matches or slightly exceeds your compressor’s output to avoid performance bottlenecks.
- Compressor Horsepower Compatibility: Match the air dryer to the compressor HP rating for optimal moisture removal and system protection.
- Pre-Filter Requirements: Many refrigerated dryers require pre-filters such as water separators and oil coalescing filters. Kits including these ensure complete moisture and oil removal, protecting the dryer and extending service life.
- Pressure Ratings: Verify the maximum inlet pressure supported by the dryer and make sure your compressor’s peak pressure does not exceed those limits to avoid damage.
- Dew Point Performance: Look for dryers with dew points around 41°F or lower for effective moisture control.
- Energy Efficiency: Features like non-cycling systems, programmable drain valves, and efficient heat exchangers reduce energy use and operational costs.
- Durability and Build Quality: Corrosion-resistant heat exchangers and robust construction materials improve reliability and longevity.
- Control and Ease of Use: Advanced microprocessor controls and easy-to-use interfaces improve system management and maintenance.
- Additional Features: Integrated regulators, electronic drains, and compatibility with standard piping sizes can enhance convenience and system integration.
By evaluating these aspects in relation to your specific compressor setup, air quality needs, and budget, you can confidently select a refrigerated air dryer that delivers dependable dry air, protects your tools and processes, and maximizes system uptime.
