Evap Cooling System CLAGGED
ASK THE EXPERT
Question 1: This recent topsy-turvey weather has turned my neighbourhood into a dust bowl. Is this likely to affect my evaporative cooler?
Answer: As we start to approach the end of summer Sharpe Group gets lots of calls from people with overworked evaporative coolers. If they haven’t been serviced and checked for a couple of years there are likely to be all sorts of issues. Underperforming pumps water pumps are one of them.
Q2: What does the pump do and what can cause it to underperform?
A: The pump is one of the hardest working parts of the system, pushing water up through the unit to moisten the filter pads. Fans then blow air through the pads to cool the airflow. After a long, hot and dusty summer there is every possibility the water reservoir is clagged with dust and other debris. This can block or fracture the pump’s impeller and run it dry. Pumps rarely last the lifespan of the unit, usual lifespan is 5 – 7 years.
Q3: What is the main symptom of a water pump underperforming?
A: You will still be getting a flow of air (as the fans continue working) but it won’t be the normal cool breeze you get from a unit that’s pumping fresh, continuous water up to the filter pads.
Q4: Is a pump replacement expensive?
A: Sharpe Group can assess your system and supply and fit a replacement pump from $308. If you have an older system we have upgrade options with pump technology improvement over recent years giving superior water flow with lower running costs, and ultimately – cooler air.
