Automatic Screen Filtration System

Overview

Our HYDRA™ Automatic Screen Filtration System is engineered to safeguard mission-critical cooling infrastructure by delivering clean, reliable domestic water to industrial Water Storage Tanks. Designed around high-performance automatic backwash filters, the system provides continuous filtration without interrupting downstream flow; ensuring stable water quality for chillers, heat exchangers and other essential cooling equipment.

The system is available with single or dual-stage filtration and includes a complete manifold with an integrated bypass. Fully automated, differential-pressure-triggered backwashing ensures consistent performance, even with variable authority water conditions. Each filter operates independently and features its own built-in bypass and dedicated drain connection, allowing for easy maintenance and long service life.

Engineered for dependability, automation, and compliance, this filtration system provides confidence that your cooling water supply remains clean, stable, and ready to support continuous uptime.
