The Oasis System | Cooling Water Treatment Malaysia | Oasis Engineering
System

Six parts. One water programme.

Every Oasis programme is built from the same parts: chemistry, dosing, filtration, chiller flushing, service and software. We specify them for your site and run them as one system.

FIG. A · energy
≈ RM{{ en.rm }} / yearfor every {{ en.dtLabel }}, on one {{ en.rt }} RT chiller

Each 1 °C rise in condensing temperature adds roughly 2–3% to compressor energy. Scale in the condenser tubes is what pushes it up.

Compressor energy only. 2.5% per °C used as midpoint. Enter your own figures.

{{ calc.pctLine }}

Most towers bleed off more than they need to: timer-based bleeds, valves left cracked open or bleeding ‘to be safe’ when conductivity is already in range. Every litre bled is a litre bought, treated and paid for again as sewerage.

Times water is reused = cycles of concentration. Mass balance at constant evaporation.
FIG. C · tube leaks
RM100k – 250k+when one leaking tube becomes a retube, on a 500 RT chiller
The cost goes beyond the tube.

A leaking condenser tube can let water into the refrigerant circuit, contaminating refrigerant and oil. What starts as one pinhole can end with the whole bundle replaced.

Eddy-current testingRM3,000 – 8,000
Plugging leaking tubesRM300 – 800 per tube
Full condenser retubeRM80,000 – 200,000
Refrigerant recovery & oil changeRM15,000 – 50,000
Chiller downtime1–2 days to plug · 2–4 weeks to retube
Indicative Malaysian ranges for a 500 RT centrifugal chiller. Excludes lost production. Every chiller differs.
