The ZL-25T FRP counter flow cooling tower delivers 87.92 kW heat rejection at 25 refrigeration tons with 19.51 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-25T.
The ZL-25T cooling tower can be configured for Clean-In-Place (CIP) compatibility through SS316L stainless steel upgrade of all wetted surfaces: fill media support frames, water distribution piping, drift eliminators, and basin. The SS316L construction allows hot water sanitization at 80°C for 30 minutes to eliminate biofilm and microbial contamination per cGMP requirements. The standard FRP version is suitable for non-sterile pharmaceutical applications (oral solid dosage, topical formulations); the SS316L upgrade is required for sterile injectables, ophthalmics, and biological products. CIP cycle frequency: weekly for sterile manufacturing, monthly for non-sterile manufacturing. The ZL-25T's smooth SS316L surfaces (electropolished to Ra less than 0.8 micron) minimize bacterial adhesion and facilitate CIP effectiveness.
Installation of the ZL-25T in cGMP pharmaceutical facilities requires comprehensive documentation for FDA inspection and qualification. Required documentation: (1) Installation Qualification (IQ) protocol with verification of specifications, materials, and installation per design; (2) Operational Qualification (OQ) protocol with performance testing at design conditions; (3) Performance Qualification (PQ) protocol with process-specific testing using actual pharmaceutical products; (4) Material certificates for SS316L surfaces (mill certificates, surface finish certificates); (5) Welding documentation for sanitary tri-clamp connections (weld maps, weld procedure specifications, welder qualifications); (6) Passivation certificates for SS316L surfaces (citric acid or nitric acid passivation); (7) Factory Acceptance Test (FAT) reports; (8) Site Acceptance Test (SAT) reports. ZILLION provides IQ/OQ/PQ templates for the ZL-25T to streamline pharmaceutical customer qualification processes.
The ZL-25T cooling tower provides precise condenser water temperature control for sterile pharmaceutical water systems (Water for Injection, Purified Water, Highly Purified Water). The 87.92 kW heat rejection capacity supports process water chilling systems that maintain 4-25°C temperatures for storage and distribution loops. The 19.51 m3/h flow rate is calibrated for use with pharmaceutical-grade heat exchangers (typically double-tube plate heat exchangers with sanitary gaskets). For Water for Injection (WFI) systems, the ZL-25T's leaving water temperature of 32°C enables chilled WFI production at 4°C through a downstream chiller, with the ZL-25T providing condenser cooling for the chiller. For Purified Water (PW) systems, the ZL-25T can support direct cooling for ambient temperature storage tanks.
The SS316L stainless steel upgrade for the ZL-25T cooling tower includes electropolishing of all wetted surfaces to a surface roughness of Ra less than 0.8 micron (typically 0.4-0.6 micron). Electropolishing removes surface contaminants, embedded iron particles, and welding oxides, leaving a chromium-rich passive layer that resists corrosion and bacterial adhesion. The smooth surface finish facilitates CIP cycle effectiveness by eliminating crevices where bacteria could shield from cleaning chemicals. ASME BPE-2009 surface finish designation: SF4 (electropolished, 0.38-0.76 micron Ra) for product contact surfaces, SF3 (mechanically polished, 0.76-1.0 micron Ra) for non-product contact surfaces. Material certificates document surface finish verification per ASTM A480 and ASME BPE standards.
Microbial control in the ZL-25T cooling tower is essential for pharmaceutical applications to prevent product contamination. Recommended control measures: (1) SS316L upgrade to eliminate FRP-associated biofilm risks; (2) UV sterilization of circulating water (optional upgrade, 254nm lamps at 30 mJ/cm² dose); (3) Chemical sanitization with chlorine dioxide (0.5-1.0 ppm residual) or hydrogen peroxide (50-100 ppm periodic); (4) Routine microbial testing (weekly total count, monthly endotoxin); (5) Temperature control to prevent Legionella amplification (maintain leaving water below 35°C); (6) Drift eliminator maintenance to prevent aerosol generation; (7) Basin drain and CIP cycle every 6 months minimum. ZILLION provides validation support for microbial control protocols and can recommend qualified service providers for pharmaceutical cooling tower maintenance.
The ZL-25T cooling tower's sanitary tri-clamp connections comply with ASME BPE-2009 standards for bioprocessing equipment piping. Connection specifications: Tri-Clover Tri-Clamp ferrule connections in 1.5 inch, 2 inch, 3 inch, and 4 inch sizes (DN40, DN50, DN80, DN100); EPDM or Viton sanitary gaskets per ASME BPE; SS316L construction with surface finish meeting SF4 designation; mill certificates documenting material chemistry and mechanical properties per ASTM A276. The ZL-25T's tri-clamp connections enable rapid disassembly for cleaning and inspection without specialized tools. For sterile connections to pharmaceutical water systems, optional orbital welding of the tri-clamp ferrules is available per ASME BPE welding standards.

Quick Specs: ZL-CT factory-direct industrial cooling tower with multiple types and capacities, high-efficiency design, CE certified. Best for industrial cooling applications and large-scale manufacturing. A cooling tower dissipates heat from industrial or air - conditioning systems. Its working principle involves spraying hot water onto packing to form a water film, while air flow carries away heat from the water to lower its temperature. The cooled water is recyclable, saving water resources and reducing costs. There are various types, such as open and closed cooling towers. Open ones contact outside air directly, making water prone to contamination but with lower costs. Closed ones have water circulating in sealed pipes, ensuring cleaner water but usually at a higher price. Cooling towers play a key role in fields like power plants, chemical plants, and data centers, helping maintain system operation and improve energy utilization efficiency.
