Chillers that survive dust and heat

What we install

An outdoor-rated cabinet with a titanium heat exchanger, because the water is cold, circulating and usually ozonated, and stainless pits under exactly those conditions. A display, a circulation pump and insulated hoses that connect low in the basin wall so nothing crosses the rim.

It runs to a setpoint in cycles and lets the insulated lid do the overnight work, which is the difference between a compressor with a life expectancy and one with a warranty period.

Dust, and how to beat it

Washable pre-filters on the intake, the grille turned away from the prevailing wind, a shaded position with real clearance, and a three-month service interval instead of six. In khamsin season, check it after the storm rather than on the calendar.

Boxing a chiller into an unventilated cupboard is the fastest way to kill one in this country.

Service

Clean the condenser, check pressures, replace the cartridge, test the ozone cell, inspect the hoses. An hour of work quarterly. On the Red Sea we add a corrosion inspection of fixings and the plant enclosure, because the salt there is more aggressive than the Mediterranean.

In short

• Titanium heat exchanger — stainless pits in cold, ozonated, circulating water
• Washable pre-filters and a shaded, ventilated position with clearance
• Three-month service interval, and after every khamsin rather than on the calendar
• Red Sea installations get a corrosion inspection as part of the visit
