Description
The Everpure Claris Large System Oman (EV4339-82, CLARIS-L-BSP) is a complete hot-beverage water treatment package built for cafes, hotels and offices running espresso machines, coffee brewers and steam equipment. It ships as a matched set: one Claris Large EV4339-12 cartridge and one Claris Gen2 filter head with 3/8 inch BSP connections. UV Water Systems stocks genuine Everpure product in Muscat and supplies it with installation and after-sales support across the Sultanate.
Why the Everpure Claris Large System Oman suits local water
Groundwater and municipal supply in Oman commonly runs 300 to 900 ppm TDS with significant carbonate hardness. In an espresso machine that hardness becomes limescale on the boiler and heat exchanger, which drives up energy use, shortens element life and eventually causes a service call in the middle of a busy shift.
The Claris cartridge tackles this with ion-exchange media that removes carbonate hardness rather than simply masking it, plus a carbon block stage that strips chlorine taste and odour. The result is water that protects the machine and lets the coffee taste the way the roaster intended.
DuoBlend bypass — set the hardness you want
The Gen2 head carries a DuoBlend bypass valve. You dial in how much untreated water blends back into the filtered stream, which lets you hit the residual hardness your equipment manufacturer or your barista actually wants. Espresso, filter coffee and steam applications each have a different sweet spot, and this system lets you tune for it instead of accepting a fixed output.

Applications in Muscat and across Oman

- Hotel and restaurant coffee stations, including Al Khuwair, Ruwi and Qurum outlets

Installation, replacement and warranty
Mount the head to a wall or the machine cabinet using the supplied bracket, connect 3/8 inch BSP inlet and outlet lines, set the DuoBlend bypass to the position your equipment calls for, then flush the cartridge before putting the machine into service. The head has integrated air vent and flush mechanisms, so cartridge changes take a couple of minutes without draining the line.
Replace the cartridge once rated capacity is reached or every 6 to 12 months, whichever comes first. In high-TDS areas of Oman the capacity limit is usually reached first, so we recommend logging your volume. Genuine Everpure product carries 12 months warranty against manufacturing defects.

Frequently asked questions
Does the Everpure Claris Large System Oman fit my espresso machine?
Yes, if the machine accepts a 3/8 inch BSP water inlet and draws 1 GPM or less. That covers the majority of one and two group commercial machines sold in Oman.
What replacement cartridge does it take?
The Claris Large EV4339-12. The Gen2 head stays in place; only the cartridge is replaced.
Can I use it on an ice machine?
Claris is optimised for hot beverage and steam applications. For ice machines we recommend the Everpure InsurIce range instead.
Do you deliver outside Muscat?
Yes. We deliver across Oman including Sohar, Nizwa, Salalah and Sur, and can arrange on-site installation.
