Overview
The Tongzhou Weipu IceLing AC Series Compact Circulating Chiller is an engineered solution for precise, stable thermal management in laboratory and analytical instrumentation environments. Designed around a closed-loop water circulation architecture, it delivers consistent cooling capacity across a broad operational range (900–5200 W), enabling reliable temperature regulation for demanding applications including laser systems, spectrometers, ICP-OES/MS sources, rotary evaporators, and high-performance liquid chromatography (HPLC) columns. Its water-cooled design minimizes ambient heat rejection, making it especially suitable for temperature-sensitive lab spaces where air-cooled units may compromise HVAC stability. The chiller operates within a precisely controlled setpoint range of 5–35 °C with ±1 °C stability—achievable through PID-based digital temperature control algorithms optimized for minimal overshoot and rapid thermal recovery after load transients.
Key Features
- Integrated stainless-steel reservoir (8–70 L, model-dependent) with corrosion-resistant construction and easy-access cleaning port
- High-efficiency centrifugal circulation pump delivering adjustable flow (3–30 L/min) and pressure (0.6–3.6 bar) to accommodate varying system backpressure requirements
- Dual-layer thermal insulation and low-vibration compressor mounting to ensure acoustic performance ≤58 dB(A) at 1 m distance
- Multi-stage fluid conditioning options: optional inline particulate filtration (≤5 µm retention), ion-exchange resin cartridge, and UV sterilization module for ultra-pure coolant loops
- Comprehensive safety architecture including real-time monitoring of flow rate, reservoir level, outlet temperature, and high-limit thermal cutoff (hardware-independent)
- Modular electrical interface suite supporting RS232/RS485 (Modbus RTU protocol), USB HID-class configuration, and dry-contact I/O for external start/stop and alarm signaling
Sample Compatibility & Compliance
The IceLing AC Series supports compatibility with a wide spectrum of laboratory instruments requiring external cooling, including but not limited to: FTIR spectrometers, X-ray diffractometers (XRD), electron microscopy cooling stages, PCR thermal cyclers, and semiconductor metrology tools. All models are CE-marked per EN 61000-6-3 (EMC Emission) and EN 61000-6-2 (Immunity), and conform to IEC 61010-1:2010 for safety in laboratory equipment. Optional configurations meet GLP-compliant data integrity requirements—including audit-trail-enabled USB logging, time-stamped event records (flow loss, temperature deviation, pump fault), and password-protected parameter access—supporting alignment with FDA 21 CFR Part 11 Annex 11 principles where electronic records are subject to regulatory review.
Software & Data Management
Unit-level configuration and real-time status monitoring are supported via native USB connection using the IceLing Control Suite—a Windows-compatible application providing graphical trend visualization, programmable setpoint ramps, and exportable CSV logs with timestamps. For integration into centralized facility management systems, the RS485 interface enables multi-unit daisy-chaining and SCADA-level polling via standard Modbus registers (e.g., register 40001 = current temperature, 40002 = pump status). All communication protocols support configurable baud rates (9600–115200 bps), parity, and timeout parameters to match legacy instrument controllers. Firmware updates are delivered via signed binary packages with CRC-32 validation to ensure version traceability and field-upgrade integrity.
Applications

- Removing waste heat from RF plasma generators used in thin-film deposition and surface analysis
- Providing chilled coolant to cryo-cooled detectors in Raman and photoluminescence measurement setups
- Thermal conditioning of sample stages in automated material testing rigs operating under ASTM D696 or ISO 6721 standards
- Supporting continuous-duty operation of high-power LED light sources in fluorescence microscopy platforms
FAQ
What is the maximum allowable inlet water temperature for the water-cooled condenser?
The unit requires a supply water temperature ≤32 °C at the condenser inlet, with recommended differential pressure ≥1.5 bar above system backpressure.
Can the chiller operate continuously at its minimum temperature setpoint (5 °C) under full load?
Yes—each model is rated for continuous operation across its full temperature range and specified cooling capacity envelope, verified per ISO 5149-2:2014 test conditions.
Is remote firmware update supported over RS485?
Firmware updates must be performed locally via USB; RS485 is reserved for operational command and telemetry only.
Does the unit include factory calibration documentation traceable to NIST standards?
Calibration certificates for temperature sensor (PT100 Class A) and flow meter (±1.5% FS) are provided with each shipment, including as-found/as-left data and uncertainty budgets.
What maintenance intervals are recommended for the optional water purification modules?
Particulate filters require replacement every 6 months or 1000 operating hours; ion-exchange cartridges every 3 months under continuous use with deionized feed water.
