As a specialized manufacturer of industrial valves and filtration solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T497 Water Filter, engineered specifically for robust cooling tower loop protection. Since our establishment in 2016, we have dedicated ourselves to producing high-quality fluid control components, serving a diverse global clientele across North America, South America, Europe, Asia, Africa, and Oceania. This 304 stainless steel filter with a 60-mesh screen is a cornerstone of our product line, designed to safeguard your critical cooling systems from particulate contamination, ensuring operational efficiency and extending equipment lifespan. Our commitment to quality, backed by ISO9001 certification, ensures you receive a reliable and durable product tailored for industrial demands.
This filter plays a vital role in maintaining the cleanliness of cooling water circuits. By effectively capturing debris, scale, and other particulates, it prevents clogging in heat exchangers, spray nozzles, and condenser tubes, which are common failure points in cooling towers. The result is sustained heat transfer efficiency, reduced maintenance frequency, and prevention of unscheduled downtime. We understand that system reliability is paramount for your operations, and our filter is built to deliver consistent performance under challenging conditions.
Key Features and Technical Advantages:
- Superior Construction: Fabricated from high-grade 304 stainless steel, the filter body and screen offer exceptional corrosion resistance, making it ideal for use with various water chemistries and in humid, outdoor environments typical of cooling towers.
- Precise Filtration: The integrated 60-mesh screen (approximately 250 microns) provides an optimal balance between filtration efficiency and pressure drop, effectively removing harmful particles without significantly impeding water flow.
- Robust Design per CB/T497: Manufactured in accordance with the CB/T497 standard, this filter ensures dimensional accuracy, pressure integrity, and compatibility with common industrial piping specifications, guaranteeing a secure and leak-free installation.
- Versatile Configuration: Available in standard Y-type or basket-type designs to suit different spatial constraints and dirt-holding capacity requirements within your piping layout.
- Low Maintenance Operation: Designed for easy access. The screen can be removed for manual cleaning quickly, minimizing system downtime. Optional automatic self-cleaning mechanisms are also available upon request for continuous operation.
- Customizable Options: While the standard offering features flanged connections, other connection types (e.g., threaded), different pressure ratings, and alternative screen meshes (e.g., 40 mesh, 80 mesh) can be customized to meet your specific project needs.

Frequently Asked Questions (FAQ):
Q1: What is the primary purpose of this filter in a cooling tower system?
A: Its main role is to protect the closed or open loop of a cooling tower by physically filtering out solid contaminants like sand, rust flakes, scale, and organic debris. This prevents these particles from circulating and causing abrasion, clogging, or fouling within sensitive components like chillers, heat exchangers, and spray nozzles.
Q2: Why is 304 stainless steel the preferred material?
A: 304 stainless steel offers excellent resistance to corrosion from water, chlorides (often present in cooling water), and atmospheric exposure. This ensures a long service life even in the harsh, wet environment of a cooling tower, making it a reliable and low-maintenance choice compared to carbon steel or plastic alternatives.
Q3: Is a 60-mesh screen suitable for my application?
A: A 60-mesh screen (approx. 250 microns) is a common and effective choice for general cooling tower protection. It captures a significant amount of damaging particulates while maintaining a manageable pressure drop. For applications with finer particulate concerns or specific water quality standards, other mesh sizes like 80 or 100 can be explored as customizable options.
Q4: How often does the filter screen need cleaning?
A: The cleaning frequency depends entirely on the particulate load in your cooling water. It can range from weekly to monthly or even longer. A noticeable increase in the pressure differential across the filter is a clear indicator that cleaning is required. We also offer optional differential pressure gauges to monitor this.
Q5: Can this filter be installed in any orientation?
A: For optimal performance and sediment collection, Y-type filters are typically installed in a horizontal pipe with the screen leg pointing downward. Basket-type filters also have preferred orientations. Our technical documentation provides specific installation guidelines to ensure proper function.
Q6: Do you provide custom connection sizes or pressure ratings?
A: Yes, customization is a key service we offer. While we stock standard flanged sizes per common specifications, we can manufacture filters with threaded connections, different ANSI/PN pressure class ratings, and non-standard port sizes based on your detailed requirements and piping drawings.
Q7: What is the lead time for an order?
A: Lead times vary based on order quantity, customization level, and current production schedule. Standard items typically have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate delivery schedule.
Q8: How does your ISO9001 certification benefit me as a buyer?
A: Our ISO9001 certification provides assurance of a consistent and controlled manufacturing process. It means every CB/T497 filter undergoes systematic quality checks for materials, dimensions, welding integrity, and pressure testing, ensuring you receive a product that reliably meets its specified performance and safety criteria.
