Chiller maintenance in Dhahban

We measure suction and high-side pressure and compare them with expected values for the refrigerant type on the unit nameplate, check the compressor thermally with an infrared camera if needed, and compare current draw with actual load conditions on the day of the visit.

Yes. Jeddah's humid, salt-laden sea air deposits a layer on outdoor condenser coils faster than in dry inland cities. This raises condensing pressure and makes the compressor work harder, which is why coil inspection and cleaning matter more here than in a dry climate.

Most maintenance and common repairs are done on site: coil cleaning, pressure adjustment, sensor replacement, control circuit repair. Work that requires internal compressor rebuilding is identified after inspection and we explain exactly what it involves.

At every visit we record refrigerant pressures, entering and leaving water temperatures, compressor current and any alarms. Comparing these readings visit by visit shows a slow loss of performance, such as a condenser coil starting to foul or a charge running low, before it turns into a shutdown.

It depends on how many chillers the building has and how the hydronic circuit is designed. With a single chiller, a full inspection needs a brief shutdown agreed with you in advance. Where more than one chiller is installed, we schedule maintenance in sequence so partial cooling stays available. The first visit establishes what is possible.

Yes, coastal humidity speeds up mould and rust on coils and pipes, so we clean the chiller every three months minimum instead of six.

We use specialized chemical solutions to remove salt and mould deposits without damaging copper and aluminium, then rinse with clean water.

Yes, we recommend extra moisture-resistant insulation on chilled water pipes to reduce external condensation and rust.

Yes, salt air accelerates corrosion of compressor metals and condenser coils, so we inspect monthly and periodically coat pipes with rust-preventive oil.
