Description
Hayward Easy Chem – pH + ORP Controller/Doser (Ref. EASY-CH-DPHRXGS)
The Hayward Easy Chem EASY-CH-DPHRXGS is an automatic pH+ORP controller that ensures the water's chemical balance through a highly reliable peristaltic pump and a socket data output. Designed for pools of up to 130 m³, it combines precision, ease of use, and a renewed design aligned with the Hayward 2025 range.
It features proportional dosing, 2-point calibration, a configurable overdosing alarm, and IP55 protection. Its original Hayward Santoprene® tube is compatible with all acid concentrations (sulfuric, hydrochloric, and multi-acid), ensuring a long service life.
Accessories included in the box: Injection valve fitting, crystal PVC suction tube, polyethylene discharge tube, connection collars (4), foot filter, FPM lip valve, PSS3 probe holder (2), mounting bracket kit, pH probe, ORP probe, pH 4 buffer solution, pH 7 buffer solution, 465 mV buffer solution, temperature sensor, and nuts for the peristaltic tube.
The installation kit is included, and its compact design (196×234×102 mm) facilitates installation even in confined spaces. Replacing the Santoprene tubes each season is recommended to maintain optimum performance.
The Easy Chem range offers versions for pH and ORP control, as well as combined dual models, enabling complete automation of chemical treatment. Some models feature precise peristaltic pumps, easy-to-read displays, and programmable alarms for safe and efficient management.
