INTELLIGENT COOLING WITH TRANSTHERM’S ADIABATIC SYSTEMS

Process Engineering Control & Manufacturing – Issue 31 2018

Transtherm’s HSE approved adiabatic solutions for cooling process water have been intelligently designed to maximise efficiency and deliver optimised operational performance in both free cooling (dry) and adiabatic (wet) modes.

With a single unit heat load capacity of between 10Kw and 3,160Kw, Transtherm’s adiabatic systems incorporate spray booster pumps to deliver up to 6 bar G of water pressure at each counter flow spray nozzle for a fine mist which is evenly evaporated across the total air stream.

Consuming around 1% of the water used by traditional cooling towers, and approximately 2% of that used by wetted surface hybrid dry coolers, these systems automatically employ a pulsed adiabatic spray operation to minimise water usage.

Intelligent features for maximum operational efficiencies

Using a digital air thermostat, Transtherm’s adiabatic systems identify when the ambient air temperature is cool enough to achieve the desired process water temperature through free cooling. This automatically triggers an integrated drain down function to empty the system of water, refilling it with a pre-programmed pre-purge function only when the ambient air temperature increases above the adiabatic trigger point.

Once the adiabatic trigger point is reached, the system will only pulse for as long as necessary in order to maintain the required process water temperature. Only when the maximum design dry bulb temperature is reached will the system operate continuously.

Integrated inlet monitoring functionality to safeguard your process facility

Preventing damage caused by inadequately cooled process water and minimising plant downtime is crucial in any process facility. Transtherm’s adiabatic systems incorporate automatic monitoring capabilities which ensure the inlet pressure to the adiabatic spray booster pump. Should the inlet pressure drop too low for correct functioning, an automatic alarm signal is triggered to either power down the adiabatic system pending repair or switch to a standby spray booster pump.
