Gardner Denver Refrigerated Air Dryers

Pinnacle Industries is an authorized distributor of Gardner Denver refrigerated air dryers. We offer a wide selection of energy efficient refrigerated compressed air dryers. These refrigerated air dryers are engineered to benefit you today and tomorrow from the tradition of durability that is Gardner Denver.

Cycling Refrigerated

Hight Inlet Temperature Refrigerated

Non-Cycling Refrigerated

RES Series – The RES Series refrigerated dryer automatically cycles the refrigeration compressor on and off in response to inlet load conditions. As the inlet air load is reduced, the refrigeration compressor cycles off, providing you with the ability to reduce energy and costs. The RES Series has an optimized cabinet design which promotes easy access from all four sides and the hermetically sealed refrigerant compressor provides high reliability and long service life. See the RES Series Brochure.

  • 90 – 675 SCFM
  • Pressure to 250 PSIG
  • Temperature to 130°F
  • No air loss condensate drains

RSD 800-3000 99% effective moisture removal at all flow rates to preserve dew point stability. Standard Grade B two-stage cold filtration ensures maximum water extraction under low flow conditions. Stage one mechanically entraps solids >10 microns with dual stainless steel orifice tubes. Stage two utilizes in-depth fiber media to coalesce water droplets and retain solid particles 3 microns and larger. Rugged digital scroll compression improves efficiency, durability and reliability and lowers decibel sound levels. Simple reliable operation results from having only two parts, a fixed upper scroll and an orbiting lower scroll. Long-life Scroll-set compression sealing surfaces are impregnated to wear-in and improve with time.Design allows back-side of dryer to be placed against the wall. Connections: compressed air inlet/outlet portals are located through the roof for easy access to interior.Cooling air flow: enters one side and exhausts out the top for better ventilation and noise reduction.Easy to remove enclosure panels.Crafted from premium grade 316 stainless steel, our exclusive plate type heat exchangers maximize Energy efficiency.Pre-filtration is not required for the heat exchangers due to smooth channels that eliminate places for dirt, rust, and scale to accumulate.Integral Blow-Gun makes heat exchanger surface cleaning easy saving time and maintaining efficiency. See RSD 800-3000 brochure.

RHT Series – These high inlet temperature refrigerated dryers feature a unique design which works directly with reciprocating air compressors. A unique heat exchanger allows the dryer to accept elevated inlet air temperatures, up to 180°F. This allows compressed air users to send high temperature air straight from their compressor directly to the RHT Series refrigerated dryer and maintain a 50°F pressure dew point. The RHT Series is ideally suited for auto body shops, auto service centers, and light industrial facilities with 5-30 hp reciprocating air compressors. See the RHT Series Brochure

  • Pressure up 250 PSIG
  • Automatic Zero-Loss Drain

RNC Series – These non-cycling refrigerated air dryers are engineered to benefit you for a lifetime with the tradition of durability that is Gardner Denver. Quality components and engineering excellence are bonded together to ensure you of a stable 38°F pressure dew point. Gardner Denver combines reliability, cutting-edge design, and innovative packaging to supply the best air treatment package in a space saving unit. The air quality delivered from an RNC Series dryer will define the difference between moderate and superior results from your plant’s processes or systems.

All models use reliable refrigeration compressors and environmentally friendly refrigerants. Models through RNC750 use proven reciprocating refrigeration compressors with R-134a refrigerant. RNC1000 through RNC3000 incorporate rugged scroll compressors with R-404a refrigerant. You benefit from long component life and efficient 24/7 performance. See the RNC Series Brochure.
