Lectrodryer - Model Type BZ -Compressed Air and Gas Dryers
The type BZ Lectrodryer is ideally suited for drying compressed air or gas. The unit is fully automatic, positive in operation and built for reliable and foolproof operation. The BZ model is a dual tower, heat reactivated solid adsorption air dryer. Normal operating range for standard units is 40-150 PSIG. Units for 300 PSIG and higher working pressures are available.
The type BZ Lectrodryer is equipped with a split stream type closed-circuit reactivation system with the Lectrodryer proportioning valve to automatically control the reactivation flow through the desiccant bed on reactivation and return it to the inlet stream to be dried with no loss of air from the system. The unit is equipped with proportioning valve, external heater, water-cooled heat exchanger (innercooler), separator and condensate trap, and all necessary controls and instruments for fully automatic operation. The adsorbers are reactivated by heating the flow of reactivating air to drive off moisture from the desiccant bed. The reactivating air is split from main stream for reactivation, then returned to the main stream without any waste. Both adsorption and reactivation circuits operate at line pressure eliminating any damage to the desiccant from buildup or bleed-down pressure on the adsorbers. The closed loop system eliminates waste or loss of flow and therefore, it can be used with explosive or expensive gases. The BZ type Lectrodryer is available for electric or steam reactivation in a wide range of standard sizes.
