The HRE Series of exhaust purge desiccant air dryers are designed & manufactured by Jemaco Flair for heavy duty applications where compressed air conservation and low dewpoints are essential. These are some of the key features of the HRE Series dryer; PLC controller as standard High performance butterfly switching valves. Low wattage heaters with large surface areas Programmable logic dewpoint controllers Minus 40ºC dewpoint performance Minus 73ºC is optional Wide variety of instrumentation options ASME vessel coded pressure vessels Compu-Purge Dewpoint control option saves air wastage RS 232 communication port as an optional extra Proven design history How It Works The exhaust purge air dryer is similar to the heatless air dryer in that there is a purge loss however, because the purge air and desiccant is heated we can reduce the purge air flow to 7% of the dryers flow rate. By reducing the purge loss by half, we greatly reduce the operating cost of the air dryer. Wet air enters the dryer and is diverted into the drying vessel where it is dried to – 40 ºC dewpoint, some 7% of this dried air is diverted into the regenerating vessel (de-sorption process) where it is heated and expanded to almost atmospheric pressure. This hot air comes into equilibrium with the desiccant and strips off the moisture thereby regenerating the back to full capacity. The wet air is then exhausted to atmosphere. The desiccant is heated for +/- 3 hrs within a 4 hr cycle, to fully regenerate it. The heater is turned off for the last hour prior to vessel changer over, to allow the desiccant to cool down. The desiccant is not effective if its temperature is above 60 ºc so the bed is cooled down with cool dry compressed air at very close to atmospheric pressure. This minimizes the potential of dewpoint spikes (bumps) when the vessels change over at the end of a cycle  Warning Large capacity dryers can be expensive to operate, ensure you have chosen the correct dryer for your application!

Aftercoolers are heat exchangers for cooling the discharge from a air compressor. They use either air or water and are an effective means of removing moisture from compressed air. Aftercoolers control the amount of water vapor in a compressed air system by condensing the water vapor into liquid form. In a distribution or process manufacturing system, liquid water can cause significant damage to the equipment that uses compressed air. An aftercooler is necessary to ensure the proper functionality of pneumatic or air handling devices that are a part of process manufacturing systems. Aftercoolers can use either air-cooled or water-cooled mechanisms.

The FLEX series are optimized air dryers for hot and humid climate in the tropical regions. An advanced stainless steel brazed plate heat exchanger is applied, and it deters refrigeration load with great efficiency of heat-transfer. The innovative and simplified refrigeration circuit provides reliable operation, low operating cost and versatile installation.

Features Minimum purge air ussage - saving the heat of adsorption maximises the moisture holding capacity of the purged air, minimising the amount required. Long desiccant life - beds size tto prevent fluidization plus slow and complete regeneration prevent desiccant movement and deterioration. Heavy duty purge exhaust muffler for quiet opperation. Non-lubricated, soft seated control valves. Stainless steel support screens and air diffusers-filters out gross contaminents, protects valves. Furnished in cabinet for easy wall mounting completely assembled, pipe, and wired shipped with full charge of desiccant only hook-up of utilities is needed to opperate. Vessels are constructed to meet the requirements of ASME code, section viii, devision 1 and stamped (optional, 55SCFM larger)  How It Works Compressed air enters the drier and is directed to left vessel by valve and then to the drier outlet through shuttle valve. A portion of the dried air is throttled to near atmospheric pressure by means of orifice. The extremely dry, low pressure air flows through and regenerates the desiccant in right vessel and is exhausted through purge/repressurization valve and exhaust muffler to atmosphere. After a set time, the automatic solid state timer closes purge/repressurization valve allowing right vessel to repressurize slowly. At the end of 3 minutes (when operating on a 6 minute cycle). Valve shifts and purge/repressurization valve re-opens. The main airflow is now dried by right vessel while left vessel is being regenerated.
