Donaldson High-Capacity Cycling Refrigerated Compressed Air Dryers Lead the Way in Air Purification

Aug. 16, 2007
When large air volumes need to be dried to a reliable and constant dew point, look to Donaldson Company (NYSE:DCI), a leading, worldwide manufacturer of filtration systems and parts, for high-capacity cycling refrigerated compressed air dryers. Donaldson's cycling refrigerated dryers, such as the RTM series, are energy efficient, cost effective and meet all application requirements. The Donaldson RTM Refrigerated Thermal Mass series has a cycling range of 2,500 – 30,000 scfm. It features multiple compressors with defined loading and unloading capacities and a thermal mass storage medium for energy-efficient operation. Unlike non-cycling dryers, the Donaldson RTM series uses predetermined temperature levels to prevent the loss of energy when demand on the dryer is low. Donaldson's high capacity cycling refrigerated compressed air dryers are assembled with quality, dependable components: – High efficiency scroll compressors, semi-hermetic compressors and rotary screws provide reliability and energy savings – High thermal efficiency stainless steel plate heat exchanger and ASME-stamped shell and tube-type pre-cooler/heater and air-to-water/glycol heat exchangers are designed for low pressure drop and maximum performance – Integrated stainless steel separators and high efficiency centrifugal separators eliminate moisture, removing 99% of water droplets with no mechanical movement and mainten ance – Built standard with air-cooled (2,500 – 5,000 scfm) or water-cooled (6,000 and up scfm) condenser and automatic water regulating valve – Demand-activated, zero-purge drain system automatically discharges contaminated condensate from the system – High efficiency close-coupled centrifugal pump with back flow preventer and no flow shutdown provides reliable performance – Allen-Bradley PCL Controller with panel view includes a variety of indicators for improved energy savings and remote monitoring capability. All Donaldson dryers are designed to provide reliable performance to CAGI ADF 100 specifications while consuming the lowest amount of energy possible.
