The Science of Compressed Air

The Science of Compressed Air CYCLING AND NON-CYCLING DRYERS Quincy refrigerated air dryers purify compressed air by chilling the air to approximately +39 F. The lower compressed air temperatures cause entrained moisture to condense. The condensed moisture carries airborne dirt and oil to the separator where it is removed from the air stream by an automatic drain. Plant equipment will run better and processes more efficiently when operated with clean compressed air. Pay back starts immediately upon startup. To customize the total air system for optimum efficiency, Quincy provides both Cycling and Non-Cycling refrigerated air dryers. Cycling dryers are of particular interest for larger systems with fluctuating loads, whereas Non-Cycling dryers are typically best suited for smaller systems or systems expecting fairly constant loads. Either way, one need not look any further than Quincy for time-proven and reliable compressed air dryers. 11 Heatless Desiccant 1.9 kw Draw 4.0 Non-Cycling Refrigerated Cycling Refrigerated PPM Moisture by Weight (Thousands) 1.4.98.67.57.51 70 60 50 40 35 32.11.01 0-40 Pressure Dew Point Temperature F 0 25 50 75 100 % load kw vs. Load 500 cfm @ 100 psig Dew Point vs. PPM 3

REFRIGERATED AIR DRYERS QPNC Non-Cycling Operation Quincy Non-Cycling Direct Expansion dryers use a two-stage heat exchanger system to maintain consistent dew points. Freeze-ups are prevented and optimum performance is maintained by integrating the highest quality components and refrigeration control valves into our system. Only the most reliable and efficient aluminum, stainless-steel and copper materials are selected for our premium heat exchangers. 10-600 cfm QPNC dryers employ an internal Electronic No Loss condensate drain. All auto drain functions and displays for 750 cfm and larger dryers are controlled by the panel mounted microprocessor. Wet compressed air enters the integral first stage air-to-air heat exchanger where it is precooled by the cold air returning from the integral evaporator. Precooling saves energy by reducing the heat load on the refrigeration system. After the air has been precooled, it flows into the air-to-refrigerant evaporator where its temperature is reduced to +39 F. This temperature reduction forces entrained moisture to condense. The mixture of condensed liquids and cold air then flow into the moisture separator where the liquids are collected in the sump and removed by an automatic drain. After liquids have been removed, the cold dry compressed air returns through the cold side of the first stage heat exchanger where it is reheated by the warm incoming air. Pipe sweating is avoided and air volume is increased by reheating. The compressed air is now considered treated and ready for delivery to the system.

The Science of Compressed Air

The Science of Compressed Air QPCD Cycling Dryer Operation Quincy Cycling Dryers save energy by turning the refrigeration system on and off in response to demand. A three-stage cold air module combined with our exclusive CSI chiller provides more cold storage and higher energy savings than conventional cycling designs. Thermostatic controls ensure proper cycling at all load conditions, provides tight dew point control and prevents freeze ups. Contaminated compressed air flows into the 3-in-1 cold air module first stage air to air heat exchanger section where it is pre-cooled by the cold air returning from the chilled mass section. Pre-cooling saves energy by reducing the heat load on the refrigeration system. The pre-cooled compressed air is then directed into the second stage of the cold air module, the air to chilled mass heat exchanger, where its temperature is lowered to approximately +35 F by the chilled mass flowing from the CSI chiller assembly. The compressed air flows into the integral moisture separator where the condensed liquids are removed by centrifugal action and sent to the sump for disposal through the microprocessor controlled drain. After the liquids have been removed, the compressed air returns through the first stage of the cold air module and is reheated by the warm, incoming air. The chilled mass circulates through the CSI stainless steel, immersed chiller where heat is removed by cold liquid refrigerant flowing through the chiller from the refrigeration system. When the microprocessor reads the low set point from the thermostat, it turns the refrigeration compressor off. When the compressor is off, no energy is used. When the microprocessor senses the upper set point, it turns the compressor on. Quincy s exclusive CSI stainless steel heat exchanger is totally immersed in the chiller reservoir eliminating radiant heat loss while preventing dew point spikes common with conventional cycling dryer designs. The Cold Air Module works in combination with the CSI chiller to optimize efficiency and reduce power consumption by as much as 6% over conventional cycling designs.
