Overview
The Tianfeng TF-LS-30000W is an integrated, air-cooled circulating chiller engineered for precision thermal management in demanding laboratory and industrial environments. It operates on a closed-loop refrigeration cycle utilizing R22 refrigerant and a hermetically sealed scroll compressor—designed for high efficiency, low noise, and long service life. The system employs a PID-controlled temperature regulation architecture, enabling stable setpoint maintenance within ±0.1 °C across its full operational range of 0–50 °C. Its thermally optimized heat exchanger consists of copper tubing with mechanically expanded aluminum fins, paired with a low-noise external rotor fan delivering 12,000 m³/h airflow. This configuration ensures consistent heat rejection under variable ambient conditions (up to 43 °C), making it suitable for continuous-duty applications where thermal drift must be minimized—such as laser source cooling, electron microscopy, X-ray instrumentation, and plasma spectrometry.
Key Features
- Hermetically sealed scroll compressor (10.32 kW output) with built-in overheat, overcurrent, and high/low pressure protection
- Dual-stage safety architecture: electrical (phase sequence & phase loss detection) and mechanical (temperature, pressure, flow interlocks)
- Stainless steel reservoir (260 L capacity) with integrated auto-refill function and corrosion-resistant plate-type evaporator
- Precision digital temperature controller (imported Japanese unit) with ±0.1 °C stability and 0.1 °C resolution
- High-efficiency circulation pump (2 m³/h @ 14 m head, 0.37 kW) — available in Italian or domestic Southern brand variants
- Electrical components from globally certified suppliers: Schneider contactors, Siemens/OMRON/Mitsubishi PLC-grade control logic, and UL-listed wiring harnesses
- Electrostatically coated steel enclosure (1610 × 900 × 1850 mm L×W×H) with modular front-panel access for serviceability
Sample Compatibility & Compliance
The TF-LS-30000W supports direct integration with a broad spectrum of analytical and process equipment requiring stabilized coolant delivery—including graphite furnace atomic absorption spectrometers (GFAAS), inductively coupled plasma optical emission spectrometers (ICP-OES), ICP-mass spectrometers (ICP-MS), X-ray fluorescence (XRF) and diffraction (XRD) systems, scanning and transmission electron microscopes (SEM/TEM), and high-power laser platforms. Its stainless steel fluid path and non-reactive internal wetted materials ensure compatibility with deionized water and common glycol-water mixtures (up to 30% v/v). The unit complies with CE electromagnetic compatibility (EMC) directives, IEC 61000-6-2/6-4 standards, and meets IP20 ingress protection requirements. While not certified for Class I Division 1 hazardous locations, it satisfies general-purpose laboratory installation codes per IEC 61010-1 and GB 4793.1 (China’s equivalent to EN 61010-1).
Software & Data Management
This chiller operates via embedded firmware with local HMI interface only—no proprietary software, cloud connectivity, or remote monitoring capability is included. All operational parameters (setpoint, actual temperature, pump status, alarm history) are displayed on the front-panel LCD. Alarm events—including compressor fault, low-flow condition, reservoir level deviation, and temperature excursion—are logged with timestamped event codes accessible via menu navigation. For regulated environments, optional analog 4–20 mA output signals (temperature and flow status) can be configured for integration into centralized SCADA or LIMS platforms. Though not natively compliant with FDA 21 CFR Part 11, audit trails may be generated externally when interfaced with validated third-party data acquisition systems meeting GLP/GMP traceability requirements.
Applications
- Laboratory instrumentation requiring precise, vibration-free cooling: GFAAS, ICP-OES/MS, XRF/XRD, SEM/TEM, Raman spectrometers
- Industrial laser systems (CO₂, fiber, diode-pumped solid-state) with thermal load >30 kW
- Vacuum deposition chambers and sputtering systems needing stable thermal sink performance
- Plasma etching and CVD reactors operating under controlled coolant temperature regimes
- Pharmaceutical QC labs using dissolution testers, HPLC column ovens, or automated sample prep stations
- R&D facilities conducting material testing under thermally constrained boundary conditions (e.g., thermal cycling validation)
FAQ
What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for continuous duty at ambient temperatures up to 43 °C, provided minimum clearance (600 mm rear/side, 1000 mm above) is maintained for unrestricted airflow.
Can this chiller operate with ethylene glycol solutions?
Yes—compatible with aqueous solutions containing ≤30% v/v ethylene glycol; viscosity and heat transfer coefficient adjustments must be factored into system design.
Is the reservoir equipped with level sensing and automatic top-up?
Yes—the stainless steel tank includes float-switch-based level monitoring and an integrated solenoid-driven auto-refill circuit.
Does the chiller support external temperature feedback control?
No—temperature regulation is based solely on internal sensor feedback; external setpoint modulation requires retrofitting with an external PID controller.
What certifications does the unit hold for international shipping?
It carries CE marking for EMC and safety (EN 61000-6-2/6-4, EN 61010-1), RoHS compliance documentation, and ISO 9001:2015 manufacturing certification from the OEM.
