Aolong ZFB-3000 X-ray Tube Water Chiller

Overview

The Aolong ZFB-3000 X-ray Tube Water Chiller is an engineered thermal management system designed specifically for continuous-duty cooling of medium-voltage X-ray tubes used in industrial radiographic inspection systems. Operating on the principle of forced-convection liquid circulation, the chiller maintains precise, stable coolant temperature and flow to prevent thermal drift and ensure consistent X-ray output intensity and focal spot stability. Its compact footprint and robust architecture support integration into both fixed NDT stations and mobile radiography setups—particularly where ambient temperature fluctuations or extended exposure cycles risk tube overheating. Unlike air-cooled alternatives, this unit delivers superior heat rejection efficiency under sustained load, directly contributing to extended X-ray tube service life and improved system uptime.

Key Features

• High-reliability closed-loop design with stainless-steel fluid path components and corrosion-resistant reservoir lining for long-term compatibility with deionized water.
• PROCON (USA) vane-type positive displacement pump ensures stable flow delivery across varying backpressure conditions typical of X-ray tube manifolds and flexible coolant hoses.
• OMRON (Japan) digital PID temperature controller provides ±0.3 °C setpoint accuracy and programmable ramping profiles to accommodate warm-up and cooldown phases during system startup/shutdown.
• High-efficiency finned-tube radiator with axial-flow fan enables effective heat dissipation without requiring external chilled water infrastructure.
• Real-time monitoring of flow rate (±0.2 L/min resolution) and coolant temperature (±0.1 °C resolution) via integrated sensors, with analog outputs available for remote SCADA integration.
• Low-noise operation (58 dB(A) at 1 m) meets ISO 7779 requirements for laboratory and production floor environments where acoustic comfort is specified.
• Compliance-ready architecture supports optional data logging modules compatible with FDA 21 CFR Part 11 audit trail requirements when deployed in regulated QA/QC workflows.

Sample Compatibility & Compliance

The ZFB-3000 is validated for use with sealed, oil-insulated X-ray tubes operating within the 160–225 kV range—commonly found in portable and benchtop industrial radiography systems (e.g., those conforming to ASTM E94, ISO 5579, and EN 462-1). It is not intended for high-energy linear accelerators (>1 MeV) or microfocus tubes requiring sub-ambient cooling. The unit complies with GB/T 14048.1 (China), IEC 61000-6-2 (EMC immunity), and IEC 61000-6-4 (EMC emissions) standards. All electrical components meet IP20 ingress protection rating per IEC 60529. As a Class II medical device auxiliary component (per MDR Annex VIII), it may be included in technical files supporting CE marking of complete X-ray inspection systems.

Software & Data Management

While the base ZFB-3000 operates as a standalone analog-controlled chiller, optional RS-485 Modbus RTU interface enables bidirectional communication with host NDT control systems. This allows centralized monitoring of real-time temperature, flow, and fault status; remote setpoint adjustment; and automated shutdown initiation upon detection of flow interruption or overtemperature events. Logged data (timestamped temperature/flow records) can be exported in CSV format for inclusion in GLP/GMP-compliant test reports. Firmware updates are performed via USB port using vendor-supplied configuration utility—no internet connectivity required to maintain cybersecurity integrity in isolated lab networks.

Applications

• Non-destructive testing of welds, castings, and composite structures in aerospace, power generation, and pipeline maintenance.
• Quality assurance in additive manufacturing process validation, where consistent X-ray source performance is critical for CT reconstruction fidelity.
• Calibration laboratories performing traceable radiation output measurements per ISO/IEC 17025 requirements.
• In-line inspection systems integrated with automated part handling and image analysis software (e.g., EFIS, DICONDE-compliant platforms).
• Radiographic film and DR panel-based imaging stations requiring stable thermal conditions to minimize quantum noise and detector lag artifacts.

FAQ

What type of coolant is recommended for the ZFB-3000?
Deionized water with resistivity ≥1 MΩ·cm is required. Glycol-based antifreeze or tap water must not be used, as they accelerate corrosion and impair heat transfer efficiency.
Can the chiller operate continuously at full load?
Yes—the system is rated for 24/7 operation at 3 kW thermal load under ambient temperatures up to 35 °C and relative humidity ≤80% non-condensing.
Is the unit suitable for integration into a Class 10,000 cleanroom environment?
The ZFB-3000 has no internal filtration or particle generation mechanisms; however, its external enclosure does not meet ISO 14644-1 particulate cleanliness requirements unless installed within an isolator or laminar flow hood.
Does the chiller include alarm relays for external interlock circuits?
Standard configuration includes two dry-contact relay outputs: one for high-temperature fault and one for low-flow condition—both configurable for normally open/closed states.
What maintenance intervals are recommended?
Pump oil replacement every 12 months; coolant exchange and system flush every 24 months; annual verification of temperature sensor calibration against NIST-traceable reference standard.
