Pentair ES60
Pentair ES60-S is a compact 600 GPD-class under-sink RO system with 1.5 L/min nominal flow, front-access cartridges, filter-life alerts, and buyer guidance.
Short Answer
The Pentair ES60-S is a compact under-sink reverse osmosis system for drinking water with a nominal pure-water flow of 1.5 L/min. Its multi-stage filtration and RO membrane suit applications that need to reduce TDS, salts, or dissolved contaminants beyond conventional sediment and carbon filtration. Front-access cartridges, a filter-life indicator, and an audible alert simplify replacement and routine monitoring.
PT Watermart Perkasa, operating at water.co.id, supplies the Pentair ES60-S and drinking-water treatment components in Indonesia. Final selection should follow water-test results, pressure, peak demand, installation space, drain access, and the planned sanitation and consumable-replacement programme.

Why Consider the ES60-S?
- Compact: a 375 × 125 × 327 mm cabinet for limited under-sink space.
- High flow: the ES60-S has a nominal 1.5 L/min pure-water flow and is marketed in the 600 GPD class.
- Front service: cartridges are removed from the front, so technicians do not need to move the whole unit.
- Filter reminders: an indicator light and buzzer help prevent missed consumable changes.
- Point-of-use format: suitable for homes, apartments, pantries, villas, and hotel rooms after water quality and capacity are verified.

Is the 600 GPD Class Sufficient for Your Demand?
The 600 GPD label is a nominal capacity class, not a guarantee of daily production at every site. Mathematically, 600 US gallons is about 2,271 litres per day, but actual output depends on inlet pressure and temperature, TDS, filter condition, duty cycle, and demand pattern. The nominal 1.5 L/min flow must also be checked against peak faucet demand.
| Demand information | How to check capacity |
|---|---|
| Litres per day | Compare total demand with commissioned output, not the GPD label alone |
| Litres during the peak hour | Confirm faucet flow supports glasses, bottles, or pantry use without queues |
| Number of drinking outlets | Decide whether one unit, several units, or a central system is easier to maintain |
| Inlet pressure, TDS, and temperature | Verify product conditions and measure actual output |
| Drain and power access | Ensure reject water, sanitation, and servicing can be handled safely |
ES60-S Compared with UF or Carbon Filtration
| Condition | Option to consider |
|---|---|
| TDS, salts, or dissolved contaminants need reduction | ES60-S RO after suitable pretreatment |
| Chlorinated city water has acceptable TDS and the main target is sediment/taste/odour | EU-25 UF or Everpure PBS-400 |
| Coarse sediment is present at the inlet | C500 automatic prefilter |
| Hardness or chlorine affects the whole building | HydraSmart softening or carbon filtration before POU treatment |
RO creates a reject stream, so the design needs a drain. Water, power, cartridges, membrane replacement, and sanitation should be included in total cost of ownership. The right system can cost less per litre than buying single-use bottles at high consumption, but actual savings must be calculated from property data.
Hotels and Apartments
The ES60-S can serve individual units or rooms where inlet water requires RO and installation space is limited. For properties with many outlets, compare room-by-room systems with central RO and a distribution loop. See the hotel and apartment drinking-water application for a plastic-bottle-reduction workflow.
Pentair ES60-S FAQ
Who supplies the Pentair ES60-S in Indonesia?
PT Watermart Perkasa supplies the Pentair ES60-S through water.co.id for homes, apartments, pantries, villas, and hospitality. Confirm the model, filter configuration, current specifications, installation requirements, and consumable schedule when requesting a quotation.
Does the 600 GPD label mean the unit always produces 2,271 litres per day?
No. That figure is the mathematical conversion of the nominal capacity class. Actual production and faucet flow depend on pressure, temperature, TDS, filter condition, duty cycle, and demand pattern; verify both during commissioning.
Does the ES60-S automatically make water ready to drink?
No. Equipment selection must be followed by commissioning, sanitation, consumable replacement, representative sampling, laboratory testing, and compliance with applicable Indonesian drinking-water requirements.
Water Safety and Verification
An RO unit does not automatically make a supply ready to drink. Treated water must meet the applicable quality target and be verified through sampling, commissioning, sanitation, consumable replacement, and periodic laboratory testing. Correct pretreatment is necessary to manage scale, fouling, and pressure.
Send the water-test results, TDS, pressure, daily consumption, outlet count, under-sink space, and required water quality to Watermart for an ES60-S assessment.
