WPO(pH/ORP), WEC(conductivity), WCT(cooling tower) and WCL(Free residual chlorine) controllers are available. Also, the extra large LCD improves legibility and ease of operation.
Stroke speed adjustment in 1spm increments allows fine flow adjustment between 1 and 360spm in continuous chemical feeding.
The EWN-W can be used in all countries thanks to the universal power supply(100-240VAC).
Newly-designed adjustable tube fittings eliminate tube twisting when fastening.
The molded pump body with a minimum of sealing surfaces meets a high level (IP65 equivalent) of both waterproofness and dustproofness.
