The FS-Curtis RNHI125 is the perfect choice for reciprocating compressors with high discharge temperatures. This industrial-grade high temperature dryer eliminates the need for a standalone separator and aftercooler, providing a complete air treatment solution in one compact, efficient unit. Designed to handle inlet temperatures up to 180°F, the RNHI125 delivers 145 scfm capacity and meets ISO 8573.1 Class 6 Dew Point Standards for reliable, consistent compressed air quality in demanding applications.


Complete Air Treatment in a Single Unit

For compressors with a high discharge temperature, such as reciprocating models without aftercoolers, the RNHI125 dryer is the ideal solution. This high-performance unit provides a single air treatment system that replaces four separate components — the aftercooler, separator, dryer, and filter. You get everything you need in one unit, simplifying installation, reducing footprint, and cutting maintenance requirements.

The automatic refrigeration temperature control system ensures stable performance for clean, dry, consistent-quality compressed air so that your equipment can operate at peak efficiency. The fan switch helps save energy at low loads, and the cleanable cabinet air filter cuts maintenance costs. Built robust for industrial applications, this dryer is designed to deliver years of reliable performance.


Key Performance Features

  • High Temperature Capability: Handles inlet temperatures up to 180°F, perfect for reciprocating compressors without aftercoolers
  • Stainless Steel Brazed Plate Heat Exchanger: Optimizes thermal efficiency, reduces pressure drop, and saves operating costs
  • Integrated 3-Micron Separator: Removes solid contaminants and 60% of oil aerosols for cleaner compressed air
  • Energy-Efficient Fan Switch: Allows operation in low ambient temperatures down to 35°F while reducing energy consumption
  • Compact Design: Small footprint (46" H x 17" W x 17" D) saves valuable floor space in your facility
  • Environmentally Friendly: CFC-free refrigerant meets modern environmental standards

ISO 8573.1 Class 6 Dew Point Standards

The RNHI125 is robust and designed to fit demanding industrial applications, performing to ISO 8573.1 Class 6 Dew Point Standards for reliable moisture control. Rated at 145 scfm capacity at 175 psig with a 50°F outlet pressure dew point, this dryer delivers consistent, quality compressed air with less than 5 psig pressure drop.


Why Choose the RNHI125?

When your reciprocating compressor runs hot, the RNHI125 high temperature dryer is engineered to handle it. With its stainless-steel brazed plate heat exchanger, this unit delivers exceptional thermal efficiency while minimizing pressure drop — translating directly to lower operating costs. The integrated 3-micron separator provides advanced filtration, removing both solid particulates and the majority of oil aerosols in a single pass.

Low maintenance is built into the design. The cleanable cabinet air filter can be serviced quickly without replacement parts, and the automatic temperature control system adjusts to varying conditions without operator intervention. The fan switch provides flexibility for operations in cooler environments, ensuring the unit performs efficiently year-round regardless of ambient temperature.

With 230V/1-phase/60Hz power standard, 1" NPT male connections, and a shipping weight of just 175 lbs, the RNHI125 is straightforward to specify, install, and integrate into your compressed air system. Its small footprint design maximizes facility space while delivering industrial-grade performance.
