Common Cooling Tower Problems
Open-Loop Cooling Systems
Cooling Towers play a crucial role in maintaining the efficiency of Condenser Water Systems. These towers, often belt-driven, utilise a belt-reduction
mechanism to drive a spindle that powers the Cooling Tower Fan. The water cascades over plastic fill, mimicking heavy rain, and as outside air is drawn
through this water, heat is removed. This allows the water to circulate continuously in what is known as an open-loop cooling system. However, this method can lead to significant water consumption.
Closed-Loop Cooling Systems
In closed-loop systems like evaporative condensers, water losses are minimised, but efficiency is compromised. The belt-driven systems, if not maintained, suffer from deteriorating belts and pulleys, causing slippage and impacting efficiency. Beyond this, neglected belt reduction systems can result in various mechanical issues, increased vibration, elevated noise levels, and heightened water consumption.
The Problem with Belt-Reduction Systems
Even well-maintained belt reduction systems experience losses, typically around 3% or more, translating to substantial power consumption in larger or multiple tower setups.
Addressing Belt Reduction Challenges
At Quantum Plant Maintenance, we specialise in addressing the challenges posed by belt-driven systems. We provide:
1. Advanced Bearing Systems
We install cleverly engineered bearing systems designed to reject water, significantly reducing the risk of grease washout and premature bearing failure.
2. High-Efficiency Drive Transmissions
Our high-efficiency drive transmissions cut down belt replacement by up to 75% and minimise losses in the drive system.
3. Direct Drive System Modification
We modify existing belt reduction cooling towers to a direct drive system, eliminating belt-related maintenance costs and OH&S risks associated with tower access
4. Cutting-Edge Motors
We employ high-efficiency IE3 Motors, with plans to introduce IE4 and IE5 drive motors, further enhancing cooling tower efficiencies.
Enhancing Efficiency through Advanced Technologies
1. Variable Speed Drives
Systems that allow normal building function during Tank cleaning outages. Intelligent systems for live tank level indication. Control systems for smooth operation without water hammer.
2. Temperature Sensors and Control Systems:
Our installations include temperature sensors and control systems, optimizing fan speed not only for the tower but also for associated equipment like chillers and Fan Coil Units (FCUs).
Maintaining Optimal Efficiency
By ensuring a constant water temperature instead of a Min-Max temperature band, the efficiency of ancillary equipment is enhanced, contributing to overall energy savings.
