ZL-125T 125 Ton Industrial FRP Counter Flow Cooling Tower - CIP Pharmaceutical
The ZL-125T FRP counter flow cooling tower delivers 439.52 kW heat rejection at 125 refrigeration tons with 97.5 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-125T.
The ZL-125T cooling tower can be configured for Clean-In-Place (CIP) compatibility through SS316L stainless steel upgrade of all wetted surfaces. The SS316L construction allows hot water sanitization at 80 deg C for 30 minutes to eliminate biofilm and microbial contamination per cGMP requirements. CIP cycle frequency: weekly for sterile manufacturing, monthly for non-sterile manufacturing.
Installation of the ZL-125T in cGMP pharmaceutical facilities requires comprehensive documentation for FDA inspection. Required documentation: Installation Qualification (IQ) protocol; Operational Qualification (OQ) protocol; Performance Qualification (PQ) protocol; Material certificates for SS316L surfaces; Welding documentation for sanitary tri-clamp connections; Passivation certificates for SS316L surfaces; Factory Acceptance Test (FAT) reports; Site Acceptance Test (SAT) reports.
The ZL-125T cooling tower provides precise condenser water temperature control for sterile pharmaceutical water systems. The 439.52 kW heat rejection capacity supports process water chilling systems that maintain 4-25 deg C temperatures for storage and distribution loops. For Water for Injection (WFI) systems, the ZL-125T's leaving water temperature of 32 deg C enables chilled WFI production at 4 deg C through a downstream chiller.
The SS316L stainless steel upgrade for the ZL-125T cooling tower includes electropolishing of all wetted surfaces to a surface roughness of Ra less than 0.8 micron. ASME BPE-2009 surface finish designation: SF4 for product contact surfaces, SF3 for non-product contact surfaces. Material certificates document surface finish verification per ASTM A480 and ASME BPE standards.
Microbial control in the ZL-125T cooling tower is essential for pharmaceutical applications. Recommended control measures: SS316L upgrade; UV sterilization of circulating water (254nm lamps at 30 mJ/cm2 dose); Chemical sanitization with chlorine dioxide (0.5-1.0 ppm residual); Routine microbial testing; Temperature control to prevent Legionella amplification; Drift eliminator maintenance; Basin drain and CIP cycle every 6 months.
The ZL-125T cooling tower's sanitary tri-clamp connections comply with ASME BPE-2009 standards. Connection specifications: Tri-Clover Tri-Clamp ferrule connections in 1.5 inch, 2 inch, 3 inch, and 4 inch sizes; EPDM or Viton sanitary gaskets; SS316L construction with surface finish meeting SF4 designation; mill certificates documenting material chemistry and mechanical properties per ASTM A276.
