KL KDL series are energy saving andenvironment friendly type refrigerated air dryer. It adapts Aluminum plate heatexchanger, mixed the pre-cooled regenerator, evaporator,gas-water separatorinto one. It improves 20% heat exchange efficient compared to other exchanger,then to reach 2-10°C dew point with less consumption along with low maintenance coststo operate.
All-in-one aluminum plate heatexchanger
KDL series refrigeration air dryer is adopted with all-in-onealuminum plate heat exchanger. The air-to-air heat exchanger,air-to-refrigerantheat exchanger (evaporator) and demisterseparator are housed in one aluminum module. It pre-cools the incoming airusing the cold air exiting the refrigerant section. It then final cools the airin the refrigerant section at which point the air stream enters a separationchamber to allow the condensed moisture to fall out. Since the air is reheatedin the regeneration section, the final humidity remains below 25%.
Eco-friendly refrigerant compressor
Each KDL air dryer is equipped with R407C orR134a refrigerant compressor. Scroll compressor offering energy savings of 20-30% when compared with piston compressors. The ability to tolerate liquidreturns coupled with 50% less moving parts render them nearly indestructibleand highly reliable.
Hot-gas by-pass valve
Each model of KDL air dryer is installedwith hot-gas by-pass valve which prevents the freezing inside the evaporator atany load condition. The valve is set during final test and no furtheradjustments are necessary.
