Cooling Tower Repairs

February 17th, 2016

Blog: When the Melbourne summer heat strikes, it really hits hard. Cooling equipment absorbs the brunt of the sizzling warmth, but even the best cooling towers in Victoria can struggle to cool and fail when the load is unbearably high. When every inner ball float valve temp sel and thermostat has been checked and rechecked, it’s time to consider internal cooling tower issues. Cooling tower repairs move the focus from your external heat exchangers, to the aqua cool water running over the air intake louvers that stands the test of time but can still trip a circuit breaker or two when the sun is really beating down on your premises.

Nothing less than fully qualified cool master technicians will do when the race is on to troubleshoot the problem. In fact, all cooling tower repairs are time-sensitive to a dedicated repair engineer because the wet bulb temperature is rising and that blunted water stream is doing nothing to alleviate matters. The tech should initiate a series of obvious fixes first. The motors are turned off. The pumps and fans, if still functioning, are also set to the OFF position. And, now that the tower is safe for thermal inspection, the real work begins. Evaporative cooling tower components are checked for damage. A blocked BAC water nozzle or damaged PVC fill pack can easily trip a breaker, so these internal components are among the first to be evaluated. Water droplet Legionella containments are a big factor when water and motors are installed in the same area, so the drift eliminators receive attention. Similarly, the water nozzle spray system could be defective. The nozzles can lose potency when they are blocked with leaves or plastic from the system, which means filters suction strainers need to be inspected, but this is all part of a highly detailed routine inspection, one designed to track faults and restore the equipment to full operability.

Evaporative or condenser cooling is a fine means of reducing an energy footprint to provide superchill water, but this capacity is limited when a weak link in the energy chain undermines cooling efficiency. The seals and casing components are naturally assessed as a matter of course during the repair process for the maxi chill effect. Next, this level of conscientious restorative skill extends beyond basic electrics. Water leaks from the basins result in chemical losses and cooling tower water should not go down the storm water drains. Instead, the cooling tower repairs ceaselessly diagnose the problem, moving from the air intake louvres to the water spray system. Strainers are dismantled and replaced if judged to be necessary. The fill pack and drift eliminators are also subject to a replacement strategy, with effective repair techs committing to the replacement of drift eliminator assemblies in under four hours. Just like the coolness of the lakeside we like to be a coolboy.

Whether an older model with weathered leaking evap co basins or seams or a newer modular unit, the repairs must always restore the tower to full functionality, which means the building air conditioning is climate-controlled once more and the tower is operating at peak energy efficiency.
