COLDWAVE refrigerated compressed air dryers HHDplus Series, 381 to 10,800 m 3 /h The HHDp Series of HANKISON ColdWave TM refrigerated compressed air dryers is one of the world's most commonly installed generations of refrigerated compressed air dryers. HANKISON ColdWaveTM refrigerated compressed air dryers boast industry-leading technology. Since L.E. HANKISON patented the Condensifilter in 1943, HANKISON engineers have continually set the industry standard for refrigerated compressed air dryer technology. ColdWaveTM heralds the next generation of HANKISON refrigerated compressed air dryers. Versions HHDp 381 to 10800 with emm Energy Management Monitor HANKISON ColdWave TM heat exchanger technology HANKISON heat exchangers feature an industry-leading design with large flat surfaces to keep pressure differences to a minimum. Dirt, rust and scale are unable to become trapped and are swept through these heat exchangers by the compressed air. Unlike many competitive designs, these do not require pre-filtration, which reduces capital, installation and operating costs. The heat exchangers used are crafted from premium grade 316SS stainless steel and feature large and smooth sinusoidal air channels that provide a low pressure drop, unparalleled performance and superior reliability. Filtration technology The integrated filte HF 9 Series at the cold point effectively removes the water volumes that result from the condensed moisture. Consistently removing moisture at low flow rates can be particularly challenging, however the clever design of the HF Series Grade 9 separators effectively solves these challenges by using two stages of filtration inside the separator cartridges. All ColdWave TM refrigerated compressed air dryers can be optionally equipped with an HF Series Grade 5 oil removal filter. This stage reduces the residual oil content to 0.01 mg/m 3 at 20 C and users can save on space and assembly work by using this type of filter. This advanced 24 volt electronic control unit has a number of userfriendly displays which can save energy, automate service intervals, display information in ten languages and add functionality Energy-saving schedule mode allows compressed air users with one or two-shift operations to schedule the dryer to turn on and off in accordance with their work schedule Automatic service intervals can be set for preventative maintenance schedules to ensure that the condenser on air-cooled units is kept dust free, as well as to advise the replacement of both the standard HF Series Grade 9 Separator/Filter element and the optional HF Series Grade 5 cold coalescing, oil removal filter every 12 months Operator interface with read-outs in ten languages as standard: English, German, French, Spanish, Italian, Polish, Danish, Dutch, Norwegian and Finnish. Read-outs include the current time, operating status (e.g. manual or schedule running modes), hours to service and total operating hours. Functions include a push-to-test button for the condensate drain, poweron and compressor-on lights, an operator alert light to indicate a required service or a fault with the refrigeration system/drain, and a dew point temperature indicator Remote monitoring of the emm from your computer via the RS-232 interface Standard NO and NC voltage-free alarm contacts Fault condition diagnostics with user-friendly text display X-DRAIN Series electronic level-controlled condensate drain
How COLDWAVE refrigerated compressed air dryers work Air drying circuit - (Figure 1) Compressed air that is saturated with water vapour enters the air-to-air heat exchanger (A), is pre-cooled by the outgoing chilled air, and then directed to the air-to-refrigerant (evaporator) heat exchanger (B) where it is further cooled by the refrigeration system. As the air is cooled, water vapour condenses into liquid droplets that are removed by the separator/filter (C) and discharged from the dryer by an automatic drain (D). The air then passes through an optional oil removal filter (E) and dry, oil-free and chilled compressed air returns through the air-to-air heat exchanger (A) where it is reheated before exiting the dryer. Figure 1 - Refrigerant circuit (A) Air-to-air heat exchanger (B) (E) Optional Refrigerant-to-air grade 5 fine oil heat exchanger removal filter (C) Grade 9 separator/filterr (D) Automatic condensate drain Digital evaporator - Refrigeration control - HDS Series - (Figure 2) Digital evaporator technology monitors the incoming heat load to determine how much cooling energy is required to maintain stable dew point control. The digital emm control interprets the raw data from the digital evaporator and translates it into the amount of cooling energy that is needed. The digital emm control opens or closes the valve in precise time blocks that load or unload the Digital Scroll refrigeration compressor to match the varying heat loads. Dew point stability is achieved using the least possible amount of electrical energy. Hot gas bypass valve - Refrigeration control - HHDp Series - (Figure 3) Designed for rugged durability, the refrigeration compressors in HHDp dryers are the workhorses of the industry. The refrigeration circuit is hermetically sealed and vaporised refrigerant enters the refrigerant compressor where it is compressed to a higher pressure then passes to the refrigerant liquefier, where the compressed refrigerant is then liquefied by heat extraction. An injector reduces the pressure of the liquid refrigerant and injects it into the refrigerant-to-air heat exchanger. The vaporised refrigerant is sucked back in by the refrigerant compressor. The hot gas bypass valve automatically regulates the refrigerating capacity required in the partial load range.

H Series refrigerated compressed air dryers for flow rates from 7,200 12,000 m 3 /h Advantages of the H Series at a glance: When they require compressed air to be dried efficiently, production facilities around the world rely on HANKISON refrigerated compressed air dryers. This is also true of the H Series, which covers flow rates from 7,200 to 12,000 m 3 /h. Thanks to the amply dimensioned separating system and streamlined heat exchanger, H Series models exhibit very low differential pressure. The air-to-air and refrigerant-to-air stainless steel plate heat exchangers have been specially developed for use in refrigerated compressed air dryers. 50% - 100% or 33% - 66% - 100% controls are applied as standard for dryer outputs from 7,200 to 12,000 m 3 /h. The automatic level control of the HANKISON X-DRAIN Series condensate drain uses a level sensor to open a membrane valve when the drain collecting tank becomes full. The condensate drains off and the electronics maintain the maximum valve opening time required to ensure that the condensate is separated safely and without a pressure drop.
