HL Series Alumimum Plate Refrigerated Air Dryer

√    Energy saving: Aluminum alloy three in one heat exchanger is designed to minimize the process loss of cooling capacity and improve the recycling of cooling capacity. Under the same processing capacity,the total input power of the model is reduced by 15-50%.

√    Efficient: The integrated heat exchanger is equipped with guide fins to make the compressed air exchange heat evenly inside. The built-in air water separation device is equipped with stainless steel filter screen to make the water separation more thorough.

√    Intelligence: Multi channel temperature and pressure monitoring,real-time display of dew point temperature, automatic record of accumulated running time, self diagnosis function, display of corresponding alarm code, automatic protection of equipment.

√    Environmental protection: In response to the international Montreal agreement, R134a and R410A environmental protection refrigerant are used for this series of aircraft, with zero damage to the atmosphere, meeting the needs of the international market.

√    Stable: It is equipped with constant pressure expansion valve as standard and intelligent temperature control as standard. When the air inlet emperature reaches 65C and the ambient temperature reaches 42C it still operates stably in the laboratory test, and it also has dual antifreeze protection of temperature and pressure. While saving energy, prolong the service life of the equipment.

Air Process:

Thecompressed air flows into the Pre-Cooler via inlet to perform preliminarycooling, then flows into cooling system evaporator to be further cooled viacooling system. The cooled compressed air is sent to the condensate separator, and the condensate liquid is discharged out of the machine viaauto-discharger. The cooled and dry compressed air will return to the heatexchanger for temperature regaining, then leave the frozen dryer via airoutlet.

Coolant Flow:

Thecoolant that flows through the Coolant Compressor is in a state of hightemperature and high pressure liquid, such liquid coolant is cooled down intomedium temperature and high pressure coolant via water cooled or air cooled condenser.The impurities are filtered via Drying Filter, and the coolant turns intolow temperature and low pressure air-liquid mixed state via capillary effect. It finally enters into the evaporator to implement heat exchangewith the hot compressed air to finish the cooling process, then returns to theCoolant Compressor and work cyclically.
