In the Saudi climate, cooling is both mission-critical and energy-intensive. We commission chilled water plants and district cooling networks from individual chiller safeties to whole-plant sequences, then verify capacity, efficiency and kW per ton with calibrated instrumentation.
The control logic that makes a plant efficient, and the interfaces that keep it clean.

FAQ
Questions, answered
How do you verify a chiller's capacity on site?
We measure chilled water flow and supply and return temperatures with calibrated instruments, together with the chiller's electrical input, then calculate delivered capacity and efficiency at the actual operating conditions. Results are compared with the manufacturer's rated performance, taking measurement uncertainty into account, using methods aligned with ASHRAE 184.
What is kW per ton, and why does it matter?
It is the electrical power drawn for each ton of refrigeration delivered — the lower the figure, the more efficient the chiller or plant. Measuring it at component and whole-plant level shows where energy is being lost and whether control sequences are working as intended.
Can you test a cooling tower when conditions differ from design?
Yes. CTI ATC-105 sets out test conditions and methods for evaluating tower capability when actual conditions differ from design. We measure water flow, temperatures, wet-bulb temperature and fan power, then evaluate capability against the manufacturer's performance curves.
What is low delta-T syndrome?
It occurs when the difference between chilled water supply and return temperatures is smaller than designed, forcing more pumping and chiller capacity for the same cooling. We diagnose it at coil, ETS and plant level; common causes include control valves, coil fouling, poor balancing and bypass flows.
