The ZL-10T's standard FRP (Fiberglass Reinforced Polyester) construction handles the majority of industrial cooling applications with circulating water pH 6.5-9.0. For chemical and pharmaceutical applications with aggressive water chemistry, the SS316L stainless steel upgrade option extends compatibility:
Standard FRP (pH 6.5-9.0): Suitable for most HVAC, light industrial, and food processing cooling. Tolerates standard water treatment chemicals (algaecide, scale inhibitor). 15-20 year service life under proper chemistry management.
SS316L Upgrade (pH 1-13): Required for chemical processing, pharmaceutical, and aggressive water chemistry. SS316L contains 2-3% molybdenum for improved chloride resistance. Tolerates pH 1-13 with proper passivation treatment. 20-25 year service life.
Chemical compatibility table (FRP standard vs SS316L upgrade):
Hydrochloric acid (HCl) 5%: FRP marginal, SS316L acceptable. Sulfuric acid (H2SO4) 10%: FRP acceptable, SS316L acceptable. Sodium hydroxide (NaOH) 5%: FRP acceptable, SS316L acceptable. Sodium chloride (NaCl) 5%: FRP acceptable, SS316L excellent. Ammonia (NH3) trace: FRP marginal, SS316L acceptable.
For specific chemical compatibility beyond this overview, request ZL-10T Chemical Compatibility Data Sheet from Zillion engineering.
For pharmaceutical manufacturers operating under cGMP (current Good Manufacturing Practice), the ZL-10T can be supplied with a complete validation documentation package:
IQ (Installation Qualification): Documented verification that the cooling tower is installed per specification. Includes foundation dimensions, anchor bolt torque values, piping connection verification, electrical wiring diagram, motor nameplate data.
OQ (Operational Qualification): Documented verification of operational performance. Includes thermal performance testing at design conditions (approach, range, flow rates), fan motor amp draw, vibration analysis, noise level measurement.
PQ (Performance Qualification): Long-term performance verification under actual operating conditions. Typically 30-90 days of continuous operation with logged temperature, flow, and water chemistry data.
The ZL-10T's standard documentation is sufficient for non-GMP industrial applications. The GMP documentation package adds approximately 5-7% to the tower cost and 2-3 weeks to delivery time. For FDA-regulated pharmaceutical manufacturing, this documentation is typically required.
The American Society of Mechanical Engineers Bioprocessing Equipment (ASME BPE) standard specifies surface finish, materials, and fabrication requirements for pharmaceutical processing equipment. For cooling towers serving pharma-grade processes, the ZL-10T's SS316L upgrade option meets the following BPE requirements:
Surface finish: Wetted surfaces (basin interior, water distribution piping, eliminator frames) electropolished to Ra <0.8 µm (32 microinch). This finish prevents biofilm adhesion and supports clean-in-place (CIP) procedures.
Material traceability: Mill certificates provided for all SS316L components, with heat numbers traceable to the steel mill's quality records.
Drainability: Basin sloped to drain, no dead legs in piping. Eliminates water stagnation points that could harbor microbial growth.
Documentation: Material Test Reports (MTRs), weld maps (where applicable), and surface finish measurement records provided in the QC documentation package.
For pharmaceutical manufacturers requiring ASME BPE compliance, specify the SS316L + Electropolish option at order placement.
For cooling towers serving pharmaceutical or biotech processes, periodic sanitization is essential to prevent microbial contamination. The ZL-10T's CIP-compatible design supports the following sanitization methods:
Hot water sanitization (80°C for 30 minutes): Standard FRP withstands 80°C continuously. The basin and piping can be isolated, filled with hot water, and circulated to achieve sanitization. Compatible with all ZL-10T configurations.
Chemical sanitization (sodium hypochlorite 200 ppm, 30 minutes): Standard FRP tolerates 200 ppm chlorine for short-duration sanitization. SS316L upgrade tolerates 1,000 ppm chlorine for more aggressive sanitization cycles.
Steam sanitization (121°C, 30 minutes): Requires SS316L upgrade. Standard FRP softens above 100°C. SS316L retains mechanical integrity through repeated 121°C steam cycles.
For CIP procedures, the ZL-10T's water distribution piping can be supplied with sanitary tri-clamp connections instead of standard flanges, enabling rapid connection to CIP supply and return headers.
For cooling towers installed in hazardous locations (chemical plants, refineries, pharmaceutical facilities with flammable solvents), the ZL-10T can be supplied with ATEX/IECEx Zone 2 certified motor and electrical components:
Zone 2 definition: Area where an explosive gas atmosphere is not likely to occur in normal operation and, if it occurs, will only exist for a short time. Typical of chemical plant areas where solvent handling is intermittent.
ATEX/IECEx motor upgrade: 0.37 kW motor with Ex e (increased safety) or Ex nA (non-sparking) protection class. Certified to ATEX II 2G or IECEx equivalent. Adds 8-12% to motor cost.
Electrical enclosure upgrades: Junction box, control switches, and cable glands all rated for Zone 2. Cable routing follows hazardous area cable standards.
For Zone 1 or Zone 0 installations, the ZL-10T would require additional purging or intrinsically safe design — contact Zillion engineering for Zone 1 specifications.
For pharmaceutical processes requiring precise temperature control, the cooling water loop may contain glycol or other heat transfer fluids instead of pure water. The ZL-10T's compatibility with common fluids:
Ethylene glycol (30% concentration): Compatible with standard FRP. Cooling capacity reduces 25-30% due to lower specific heat and increased viscosity. The ZL-10T's 7.81 m³/h flow becomes effectively 5.5-6.0 m³/h cooling capacity.
Propylene glycol (30% concentration): Compatible with standard FRP. Preferred for food and pharmaceutical applications where ethylene glycol toxicity is a concern. Same cooling capacity reduction as ethylene glycol.
Sodium chloride brine (10% concentration): Compatible with FRP. Cooling capacity reduces 15-20%. Used in food processing for low-temperature applications.
Silicone oil: Not recommended for open cooling towers — flammable and may damage FRP at elevated temperatures.
For closed-loop heat transfer systems where the cooling tower's water circuit is isolated from the process loop (plate heat exchanger between them), the ZL-10T sees only clean water, and the process-side fluid compatibility is independent.
Standard FRP construction handles pH 6.5-9.0 (covers most industrial applications). SS316L upgrade option extends compatibility to pH 1-13 (chemical and pharmaceutical applications). 20-25 year service life with SS316L.
Yes. The ZL-10T can be supplied with a complete IQ/OQ/PQ validation documentation package: Installation Qualification, Operational Qualification, and Performance Qualification. Adds 5-7% to tower cost and 2-3 weeks to delivery time.
SS316L upgrade option meets ASME BPE requirements: electropolished wetted surfaces to Ra <0.8 µm (32 microinch), material traceability with mill certificates, drainability with sloped basin, complete QC documentation package.
Hot water sanitization (80°C, 30 minutes) standard for all configurations. Chemical sanitization (200 ppm chlorine, 30 minutes) standard FRP, 1,000 ppm SS316L. Steam sanitization (121°C, 30 minutes) requires SS316L upgrade. CIP-compatible with sanitary tri-clamp connections.
Yes. ATEX II 2G or IECEx Zone 2 certified motor available as upgrade (Ex e increased safety or Ex nA non-sparking). Junction box, control switches, and cable glands all rated for Zone 2. Adds 8-12% to motor cost.

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.
