Defoamer for Industrial Circulating Water

In many industrial processes, circulating water is essential for cooling, heating, and various other functions. However, foam buildup within these systems (like cooling towers and closed loops) can become a significant operational headache, reducing heat transfer efficiency, causing pump cavitation, and potentially leading to overflows.

INVINO provides high-performance defoamers for industrial circulating water, specifically designed to control foam in these demanding environments, ensuring system reliability and efficiency.

Benefits of Defoamers in Circulating Water Systems

Using a specialized defoamer (like INVINO-1920) in your circulating water system offers critical advantages:

  • Improved Heat Transfer Efficiency: Prevents foam layers that act as insulators on heat exchange surfaces.
  • Reduced Water Loss & Chemical Consumption: Minimizes overflows caused by foam, conserving water and treatment chemicals.
  • Pump Protection: Prevents pump cavitation caused by entrained air, extending equipment lifespan.
  • Enhanced System Reliability: Ensures smooth, uninterrupted operation of cooling towers and other circulating water systems.
  • Compatibility: Our defoamers are compatible with common water treatment chemicals (like scale inhibitors and biocides).

    Q&A: Optimizing Cooling Tower Efficiency

    Q: How does foam affect Cooling Tower performance?
    Foam is not just a visual nuisance.
    1. Pump Cavitation: Foam entering the circulation pump causes air locks and vibration, damaging the impeller.
    2. Reduced Cooling: Foam acts as a thermal insulator on heat exchanger surfaces, reducing the heat transfer efficiency.
    3. Overflow: Uncontrolled foam blows out of the tower, carrying chemicals into the environment.
    Q: Can it control foam caused by Biocides and Slime Stripping?
    Yes. Non-oxidizing biocides (like Quaternary Ammonium Salts) and slime strippers are potent surfactants that cause massive foaming. Our defoamers are chemically designed to neutralize this specific type of "Surfactant Foam" instantly without reducing the efficacy of the biocide itself.
    Q: Is it compatible with Scale and Corrosion Inhibitors?
    Absolutely. Our circulating water defoamers are typically non-ionic or modified polysiloxanes. They do not react with negatively charged scale inhibitors (phosphonates/polymers) or corrosion inhibitors, ensuring the complete water treatment program remains balanced and effective.
    Q: Will the defoamer clog spray nozzles or filters?
    No. Unlike cheap silicone oils that form "grease balls," our products are formulated for high dispersion. They emulsify completely in the bulk water, passing easily through fine spray nozzles and side-stream filters without leaving sticky residues or causing back-pressure build-up.
    Q: What is the best dosing strategy: Shock or Continuous?
    For circulating water, **"Shock Dosing" (Slug Feeding)** is usually more effective. Adding a larger amount (e.g., 50-100 ppm) once a day (or whenever biocide is added) knocks down the foam immediately and is more economical than a continuous low-dose drip, which the foam might eventually adapt to.
