Structured Manufacturing Data (2026)

Water Tank

Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Water Tank used in the Electrical Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Water Tank is characterized by the integration of Fill Opening/Cap and Water Level Indicator. In industrial production environments, manufacturers listed on CNFX commonly emphasize Food-grade plastic (e.g., PP, ABS) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A container that stores water for evaporation in a humidifier.

Technical details and manufacturing context for Water Tank

Definition
The water tank is a reservoir component within a humidifier that holds the water supply. It feeds water to the humidification mechanism (ultrasonic transducer, wick, or heating element) and typically features a fill opening, level indicators, and may include anti-microbial treatments to prevent bacterial growth.
Working Principle
The tank stores water at atmospheric pressure. Water is drawn from the tank via gravity, a pump, or capillary action (depending on humidifier type) to the active humidification area where it is converted into moisture vapor.
Common Materials
Food-grade plastic (e.g., PP, ABS), Stainless steel
Technical Parameters
  • Capacity - the volume of water the tank can hold, determining runtime between refills. (L) Per Request
Components / BOM
  • Fill Opening/Cap Part
    Provides access for adding water and seals the tank to prevent spills and contamination.
    Material: Plastic (often with rubber gasket)
  • Water Level Indicator
    Visual or electronic gauge showing remaining water volume.
    Material: Plastic, glass, or electronic sensor
  • Outlet/Port Part
    Connection point where water exits the tank to the humidification mechanism.
    Material: Plastic
  • Base/Sealing Surface Part
    Ensures a tight, leak-proof fit when the tank is seated on the humidifier base.
    Material: Plastic (often with rubber seal)

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric (non-pressurized storage)
flow rate: N/A (static storage vessel)
temperature: 5°C to 50°C (ambient water storage range)
slurry concentration: 0% (clean water only, no suspended solids)
Media Compatibility
✓ Potable water ✓ Deionized water ✓ Humidifier-treated water with additives (e.g., bacteriostatic)
Unsuitable: Corrosive chemicals or high-concentration saline solutions
Sizing Data Required
  • Daily water consumption rate (L/day)
  • Humidifier refill frequency (hours)
  • Available installation footprint (dimensions)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion
Cause: Electrochemical degradation of tank material due to water chemistry (pH, dissolved oxygen, chlorides) or galvanic action from dissimilar metals in contact.
Structural fatigue cracking
Cause: Cyclic stresses from water level fluctuations, thermal expansion/contraction, or inadequate support leading to crack initiation and propagation, often at weld seams or stress concentrators.
Maintenance Indicators
  • Visible rust streaks, pitting, or blistering on tank surfaces (especially at welds or waterline)
  • Audible dripping or hissing from tank shell, or sudden unexplained water level drops indicating leaks
Engineering Tips
  • Implement routine internal inspections and non-destructive testing (e.g., ultrasonic thickness gauging) to monitor corrosion rates and plan proactive repairs.
  • Install cathodic protection systems (sacrificial anodes or impressed current) and maintain proper water treatment to control corrosion chemistry.

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 - Quality management systems ANSI/NSF 61 - Drinking water system components DIN 1988-100 - Technical rules for drinking water installations
Manufacturing Precision
  • Wall thickness: +/-5% of nominal thickness
  • Overall dimensions: +/-10mm for tanks up to 5000L capacity
Quality Inspection
  • Hydrostatic pressure test (typically 1.5x working pressure)
  • Visual and dimensional inspection per manufacturing drawings

Frequently Asked Questions

What materials are recommended for water tanks in electrical equipment humidifiers?

Food-grade plastic materials like PP or ABS, or stainless steel, are recommended for corrosion resistance and safety in humidifier applications.

How does the water level indicator work in these tanks?

The water level indicator typically uses a transparent section or float gauge to visually monitor water levels, ensuring proper humidifier operation.

Why is a sealing surface important for humidifier water tanks?

A proper sealing surface prevents leaks and maintains consistent humidity levels, protecting sensitive electrical equipment from moisture damage.
