Crystal Quest 185 GPM Demineralizing (DI) Water Filtration System

Overview

The Crystal Quest 185 GPM Demineralizing (DI) Water Filtration System is a high-capacity commercial water treatment system designed to reduce dissolved ionic contaminants and produce high-purity demineralized water for applications requiring low mineral content.

With a 185 GPM service flow rate and up to 250 GPM peak flow, the system provides a high-capacity demineralization solution for laboratories, medical and healthcare facilities, manufacturing processes, industrial operations, and other commercial applications requiring controlled water quality.

The system uses 20 ft³ of demineralizing multi-media and is constructed with a heavy-duty composite fiberglass mineral tank and high-flow distribution components. The 185 GPM configuration is designed for large commercial installations requiring substantially greater treatment capacity than the lower-flow DI systems.

Flow Rate & Capacity

The 185 GPM system is designed for high-volume commercial and industrial water treatment applications:

• Service Flow Rate: 185 GPM
• Peak Flow Rate: 250 GPM
• Backwash Flow Rate: 35 GPM
• Demineralizing Multi-Media: 20 ft³
• Mineral Tank: 36" × 72"
• Pipe Size: 2" / 3"
• Operating Pressure: 35–60 PSI
• Quartz Support Media: 200 lb
• Approximate Space Required: 40" × 192"

Final system configuration and connection requirements should be confirmed according to the installation and selected control configuration.

Control Head Configuration

The 185 GPM Demineralizing (DI) Water Filtration System uses a commercial automatic control-valve configuration designed for high-flow water treatment applications.

Crystal Quest specifies 3150 / 3900 electronic control valve configurations for the 185 GPM system, with the appropriate valve and connection arrangement determined by the selected system configuration.

Automatic control provides convenient system operation with controlled backwash functionality appropriate to the system's capacity and installation requirements.

Please select the required configuration from the available product options. The exact control valve and connection specifications are determined by the selected system configuration.

Applications

The Crystal Quest Demineralizing (DI) Water Filtration System is suitable for high-capacity commercial and industrial applications requiring reduced dissolved mineral and ionic content, including:

• Laboratory water treatment
• Medical and healthcare facilities
• Industrial process water
• Manufacturing applications
• Boiler and equipment feed-water treatment
• Polishing or treatment within multi-stage water purification systems
• Commercial and industrial applications requiring demineralized water

For applications requiring additional microbial control, the system may be paired with an appropriately sized UV water sterilizer. UV systems should be selected according to the required treatment flow rate.

Final system selection should take into account feed-water quality, required product-water quality, required service flow rate and the intended application.

Replacement Media & Maintenance

Demineralization media has a finite treatment capacity. Service life depends on factors including feed-water chemistry, dissolved ion concentration, water consumption and required product-water quality.

Replacement or regeneration requirements therefore vary between installations. For applications with strict water-purity requirements, product-water quality should be monitored to determine the appropriate servicing or media replacement interval.

The 185 GPM system contains 20 ft³ of demineralizing multi-media. Compatible replacement media and components should be selected according to the specific system configuration.

Important Configuration Information

This product covers the Crystal Quest 185 GPM Demineralizing (DI) Water Filtration System.

The system has a 185 GPM service flow rate and up to 250 GPM peak flow. Crystal Quest specifies 3150 / 3900 electronic control valve configurations and 2" / 3" piping for this capacity.

Control valve, connection arrangement, backwash requirements and other specifications depend on the selected system configuration and installation requirements.
