EZ-Size™ HD

Self-cleaning Filtration System for Difficult Samples

The EZ-Size™ HD or “Heavy Duty” is a filtration system developed to make solid-free samples from heavily charged liquids available for on-line analysis.  Devoid of complex engineering and equipped with large-bore pneumatic ball valves for sample intake and drain, this filtration system can handle the difficult properties of water charged with high levels of insoluble constituents.

  • Self-cleaning sample filtration with various pore sizes
  • Static pressure regulator assures a constant, readily available sample level at atmospheric pressure
  • PLC or analyzer controlled cleaning frequency

Reduced maintenance
All AppliTek filtration and preconditioning systems are designed for fully automatic operation and require virtually no human intervention. Basically all systems are incorporated with a blow-back action by instrument air. This fundamental design principle does not merely allow trouble-free sampling, moreover it contributes to high up-times. The design and choice of materials of our systems is second to none and make them ideal to be used in many applications, even for non-AppliTek analyzers.

The EZ-Size™ HD is also known as the Hach EZ9100 Series and available worldwide through your local Hach team.
