About the Product

Coffee Machine Depot USA: Authorized Distributor of Pentair Dual-Cartridge Water Treatment Systems

Coffee Machine Depot USA proudly stands as the authorized distributor for Pentair, presenting the QTSX-2PG dual-cartridge water treatment system. Designed to significantly improve water quality, this system features two 15” Qwik-Twist cartridges, capable of reducing sediment to a remarkable 0.5 microns and effectively decreasing chlorine, taste, and odor. It boasts a flow rate of 1.0 gallons per minute (gpm) and is guaranteed to treat up to 22,500 gallons of water. The inclusion of a ScaleX2 cartridge, employing revolutionary chemical-free scale inhibition technology through template-induced crystallization, prevents the buildup of calcium-carbonate scale, enhancing the longevity and efficiency of your equipment.

System Advantages:

  • Enhanced Equipment Longevity: Regular maintenance needs and costs are significantly reduced, while the lifespan of boilers, steam generators, and coffee machines is extended.
  • Superior Scale Prevention: The ScaleX2 technology shields your equipment from scale formation and accumulation, ensuring optimal performance.
  • Advanced Filtration: With gradient-density sediment filtration, the system offers protection against dirt, rust, and debris as small as 0.5 microns, while high-capacity activated-carbon filtration improves water taste and safeguards against chlorine.
  • Ease of Installation: Features like a sturdy, powder-coated mounting bracket, full-flow inlet shut-off valve, and quick, sanitary filter replacement with Qwik-Twist cartridges simplify the installation and maintenance processes.
  • Included Pressure Gauge Kit: Monitoring your system’s performance has never been easier.


Ideal for coffee and tea services and boiler-based steam generators where water hardness and chlorine content are concerns, supporting applications up to 1.0 gpm.

Installation Recommendations:

Ensure the feed-water connection is exclusively cold, adhere to specified temperature and pressure limits, and maintain a 3” clearance below the system for hassle-free filter replacement. Each system comes with a comprehensive manual covering installation, operation, and maintenance, requiring no activation or flushing to start.

Cartridge Replacement and Maintenance Tips:

To ensure the best performance, it is recommended to replace pre/post-filters and mineral addition cartridges every 6 months, or sooner if capacity is reached or feedwater pressure decreases. The lifespan of the membrane varies with feedwater quality and maintenance, typically between 12-18 months, potentially extending up to 3-5 years under optimal conditions. Note that this product is intended for commercial use and must adhere to the manufacturer’s installation and maintenance guidelines.

Safety Note:

Use this system only on water that is known to be safe or has been adequately disinfected before and after passing through the system.
