Steamers, combi ovens and steam-jacketed kettles work harder in Kuwait than almost any other kitchen equipment. They boil water off all day, and every litre that turns to steam leaves its minerals behind on the hottest surfaces. Everpure Kleensteam systems, made by Pentair, are built for exactly this job: they filter the feed water and stop limescale forming inside steam equipment.
This guide explains what Kleensteam is, which model suits which equipment, the installation limits from Pentair's own specification sheet, and how to keep it working on a Kuwait site. Sovereign Water supplies, installs and maintains Kleensteam systems for hotels, restaurants, central kitchens and catering units across Kuwait.
TL;DR
- Kleensteam combines carbon block filtration with Hydroblend scale-inhibitor media in one system for commercial steam equipment.
- Kuwait's mains water is desalinated seawater blended with brackish groundwater, so hardness varies, and steam equipment concentrates whatever arrives.
- Models range from the compact Kleensteam CT (6.3 litres per minute) to the Kleensteam II Twin (18.9 litres per minute).
- Pentair sets a working pressure of 0.7 to 8.6 bar and a maximum inlet water temperature of 38°C.
- Change the 7CB5 filter cartridge every 6 months, and the SS-10 scale cartridge before its Hydroblend compound runs out.

What Is Everpure Kleensteam?
Kleensteam is a complete water treatment package for commercial steam applications. Pentair describes the Kleensteam II as its second generation of total water treatment for steam, with filtration, scale inhibition and deliming in one assembly.
It does three jobs:
| Stage | Part | What it does |
|---|---|---|
| Filtration | 7CB5 carbon block cartridge | Reduces sediment, rust, and chlorine taste and odour, and reduces chlorine-induced corrosion |
| Scale inhibition | SS-10 cartridge with Hydroblend compound, in the SR-X bowl | Stops limescale forming in high-temperature steam equipment |
| Deliming | Dip tube and Everpure ScaleKleen | Lets you delime the boiler through the SR-X bowl, without hazardous chemicals or special piping |
Pentair says the SS-10 cartridge is more effective where alkalinity, hardness, dissolved solids or temperature are higher. No electrical connection is needed.
Why Kuwait Water Scales Steam Equipment
Kuwait has no rivers and very little fresh groundwater, so its drinking water comes from desalination. Desalinated water is very low in dissolved salts, so it is mixed with brackish groundwater before it is piped to buildings, to meet World Health Organization guidelines (Fanack Water). That blend puts calcium, magnesium and other minerals back into the supply, and the amount can shift between districts and through the year.
A glass of that water may taste fine. Inside a steamer, it behaves differently. The water boils off, the minerals stay, and the concentration in the steam generator rises with every cycle. The result is a hard crust on elements and probes. A building's storage tanks and pipework can add sediment on the way to the kitchen too.
Our guide to water quality in a Kuwait commercial kitchen covers the wider kitchen picture, and TDS and ppm in Kuwait explains the readings.
What Scale Costs a Busy Kitchen
Scale insulates a heating element. The element runs hotter and longer for the same output, which raises energy use and shortens its life. In steam generators and combi ovens, scale also coats level probes and blocks steam outlets. The first signs are usually longer cook times, uneven results and fault codes, well before a part fails.
Then there is descaling. Manual deliming takes the equipment out of service, ties up staff or a technician, and uses acid descalers. In a hotel banqueting kitchen or a central production unit running steam from early morning, an oven out of service is lost output. Preventing scale at the inlet is almost always cheaper than removing it later.
Choosing the Right Kleensteam Model
Size the system to the water flow your equipment draws at peak, not to the cartridge price. Pentair lists four models.
| Model | Pentair item | Connection | Maximum service flow |
|---|---|---|---|
| Kleensteam CT | EV979750 | 3/8" FNPT | 6.3 litres per minute (1.67 gpm) |
| Kleensteam II Single | EV979721 | 3/4" FNPT | 9.5 litres per minute (2.5 gpm) |
| Kleensteam II Twin | EV979722 | 3/4" FNPT | 18.9 litres per minute (5.0 gpm) |
| Kleensteam II Twin without feeder | EV979740 | 3/4" FNPT | 18.9 litres per minute (5.0 gpm) |
All four are rated for feed water alkalinity of 2 to 12 grains per gallon. Source: Pentair Everpure, Kleensteam systems.
The Kleensteam II Single ships with one 7CB5 cartridge and a plug in its second filter head. Adding a second 7CB5 takes it to the dual-cartridge rating of 18.9 litres per minute, so a kitchen that plans to add equipment can grow into it. Pentair is clear that service flow must not go above the rated figure. Going over it cuts both filtration and scale protection.
Installation Limits from Pentair's Specification Sheet
| Item | Kleensteam II Single (EV9797-21) |
|---|---|
| Working pressure | 0.7 to 8.6 bar (10 to 125 psi), non-shock |
| Maximum inlet water temperature | 38°C (100°F) |
| Feed line | 1/2" minimum, 3/4" preferred |
| Connect to | The boiler feed water line only, never the condenser line |
| Mounting | Vertical, cartridges hanging down, with 6.35 cm clearance below for cartridge changes |
| Overall size (H x W x D) | 64.7 x 52.0 x 17.7 cm |
| Operating weight | 14.5 kg |
| Electrical connection | None |
The 38°C inlet limit matters in Kuwait. In summer, water from a rooftop tank or a pipe run through a hot ceiling void can arrive warm, so our site survey checks the feed temperature at the planned install point. The wall also has to carry the full operating weight, and the cartridges need room below for changeouts.
Maintenance on a Kuwait Site
Pentair's operating guidance is simple, and it only works if someone follows it.
| Task | When |
|---|---|
| Change the 7CB5 cartridge | Every 6 months, or sooner if its capacity is reached or pressure falls below 0.7 bar |
| Change the SS-10 cartridge | Before the Hydroblend compound is completely used up |
| Flush the cartridges | For 5 minutes at full flow, at installation and at every cartridge change |
| Delime the equipment | As needed, by fitting the dip tube in place of the SS-10 and dissolving ScaleKleen in the SR-X housing |
Harder water, higher volumes and longer service days all use the media faster. Our Comprehensive Maintenance plans book cartridge changes on a fixed schedule and log each visit, so protection never lapses between changes.
When Kleensteam Needs Help
Kleensteam is designed for feed water within its 2 to 12 grains per gallon alkalinity range. Where the water is outside that range, or very hard or high in dissolved solids, an upstream stage protects both the cartridges and the equipment. That may be a commercial softener or, for the most demanding sites, reverse osmosis. Our commercial water softener guide for Kuwait and reverse osmosis guide explain when each makes sense. Always check the steam equipment maker's own water requirements as well, because some set limits on softened or RO water.
How Sovereign Water Supports Kuwait Kitchens
We start with a site survey. It covers the steam equipment on the line, peak flow, pressure, feed temperature, wall space and drain access. From there we specify the right Kleensteam model and any pre-treatment, supply and install it, flush and commission it, and train your team. Planned maintenance then keeps cartridges changed on time, with one point of contact for every site.
Frequently Asked Questions
What equipment is Everpure Kleensteam designed for?
Commercial steam equipment, including foodservice steamers, combi ovens and steam-jacketed kettles. It connects to the boiler feed water line only.
Does Kleensteam remove limescale that is already there?
No. It stops new scale forming. Existing scale should be removed first. The system also supports periodic deliming, using a dip tube in place of the SS-10 cartridge and Everpure ScaleKleen dissolved in the SR-X housing.
Which Kleensteam model do I need?
It depends on the peak flow your equipment draws. The Kleensteam CT is rated to 6.3 litres per minute, the Kleensteam II Single to 9.5 litres per minute, and the Kleensteam II Twin to 18.9 litres per minute.
How often are the cartridges changed?
Pentair recommends changing the 7CB5 cartridge every 6 months, or sooner if its capacity is reached or pressure drops below 0.7 bar. The SS-10 is changed before its Hydroblend compound runs out.
Does Kleensteam need electricity?
No. The system needs a water connection only, with no electrical supply.
What warranty does Kleensteam carry?
Pentair gives a limited 5-year warranty on the system against defects in material and workmanship, and a limited 1-year warranty on replaceable cartridges.
