Choosing a System Style: Quencher vs. Cape Colville

We want you to choose the exact setup that fits your boat’s layout, not your wallet.
Because of that, we price our Quencher systems exactly the same as our equivalent Cape Colville systems. Cost isn't a factor here - it’s entirely down to where you want to control the system from.
No matter which layout you choose, both systems share the exact same heavy-duty, high-quality mechanical components under the hood.

1. The Quencher System (Cabin Control)

The Quencher was designed to bring system operation out of the bilge or engine room and right into your main cabin. For most boat owners, this is the most convenient and popular choice.

  • You're in control: The electronic panel is easy to use, but it isn't automated. You flip the switches yourself, so there are no surprise cycles or error codes.
 
  • Effortless Operation: A quick start-up procedure gets fresh water into your tanks instantly. When you're done, a simple freshwater flush cycle triggers at the flick of a switch, protecting your membranes until next time.
 
  • Discreet Installation: The compact control panel requires just two hoses (high-pressure supply and low-pressure discharge) routed to the cabin. It can be cleanly flush-mounted into your cabinetry, or surface-mounted using our optional stand-off bracket.
​
  • Galley Sample Valve: The separate Sample/Tank valve is designed to be installed tucked away out of sight - usually in the locker right under the galley sink - making it easy to test your water straight into the basin.

   2. The Cape Colville System (Centralised Service Area)

The Cape Colville is our original, classic layout. It is best suited for boats where you want absolutely everything - hoses, valves, gauges, and controls centralised in a single, dedicated machinery space.
​
  • Maximum Simplicity: Everything routes through one heavy-duty panel. There are no separate components split between the cabin and the bilge, everything is right in front of you.
 
  • Installation Locations: This style is perfect for installation directly in an engine room, a dedicated cockpit locker, or a utility service area where you don't mind stepping away from the cabin to run the system.
