Improve Efficiency and Maintain the Lifespan of Your Cooling Tower with HYROTECH Equipment

Cooling towers are the heart of cooling systems in many industries. However, their optimal performance is highly dependent on the right supporting equipment. Without adequate accessories, cooling towers are prone to problems such as scaling, corrosion, biological growth, and water and energy waste. HYROTECH provides complete solutions to protect your investment and ensure that your cooling towers operate at peak efficiency.

1. Automatic Blowdown Controller: Intelligent Partial Water Drainage Control.

Blowdown is key to controlling mineral concentration (TDS) in water. HYROTECH offers two types of automatic blowdown controllers:

  • Timer-based:

    • How it works: This system discharges water (blowdown) based on a predetermined time interval, for example, every 2 hours at 1m3 or every 4 hours at 1m3.

    • Advantages: Simple, reliable, and lower initial cost. Suitable for systems with stable load and make-up water quality.

    • Description: Although economical, this system is less responsive to sudden TDS fluctuations, potentially leading to water wastage or suboptimal TDS concentration.

  • Based on TDS Sensor:

    • How it works: This system uses a TDS sensor that continuously monitors the concentration of dissolved solids in the circulating water. Blowdown will only be activated when the TDS level exceeds the specified set point.

    • Advantages: Highly precise, significantly saves water and chemicals, and maintains optimal water quality. This is the most efficient solution.

    • Description: The initial investment is higher, but the ROI (Return on Investment) is very fast through large operational savings.

2. Sidestream Filter: Continuous Particle Filtration

This filter continuously filters a portion of the cooling tower circulation water to remove suspended solids such as mud, sand, and debris.

  • Function: Prevents clogging of nozzles and fillers, reduces under deposit corrosion, and improves heat transfer efficiency.

  • HYROTECH Advantages: Designed with effective filter media and an easy backwash system, ensuring smooth operation with minimal maintenance.

3. Self-Cleaning Filter: Continuous automated filtration

An improvement on the sidestream filter, this filter has an automatic cleaning mechanism without stopping the main flow.

  • How it works: When the differential pressure across the filter element reaches a certain point, the system automatically performs a backwash cycle to clean out trapped debris.

  • Benefits: Saves labour, ensures uninterrupted filtration, and is ideal for applications with high dirt loads.

4. Chemical Dosing System: Accurate & Safe Chemical Handling

This system automatically injects chemicals (corrosion inhibitors, biocides, anti-scalants) into the cooling tower system at the correct dosage.

  • Components: Consists of a dosing pump, chemical tank, and controller.

  • HYROTECH Advantages:

    • High Accuracy: Ensures chemical concentration is always at an effective level.

    • Safety: Reduces direct operator contact with chemicals.

    • Cost Efficiency: Prevents wasteful overdosing or underdosing.

5. Hardness Controller: Intelligent Scale Prevention

Water hardness (calcium & magnesium) is the main cause of scaling. This controller specifically monitors the hardness level in circulating water.

  • How it works: The sensor detects an increase in scale levels, which is often an early indication that the system is approaching saturation and has the potential to form scale.

  • Action: The controller can be integrated with an automatic blowdown or chemical dosing system to take corrective action, such as increasing the blowdown frequency or adjusting the anti-scalant dose, before scale forms.

Conclusion:

Investing in cooling tower support equipment is not an expense, but a strategic step to optimise operating costs and extend asset life. With HYROTECH's complete range of products—from automatic TDS control and reliable filtration to precise chemical dosing—you can build a comprehensive defence system for your cooling tower.
