Coolium LX-600 Precision Circulating Chiller

Overview

The Coolium LX-600 Precision Circulating Chiller is an integrated, air-cooled thermal management system engineered for laboratory environments requiring stable, high-fidelity temperature control of external equipment. It operates on a closed-loop refrigeration cycle utilizing a hermetically sealed compressor, optimized condenser airflow, and a PID-driven digital temperature controller—eliminating on/off cycling to ensure continuous, non-pulsed cooling delivery. The unit maintains setpoint temperatures within ±0.1 °C across its operational range of 5–35 °C (at 25 °C ambient), making it suitable for applications where thermal drift directly impacts measurement integrity—such as laser spectroscopy, X-ray diffractometers, ICP-OES plasma sources, and high-resolution chromatography detectors. Its compact footprint (290 × 550 × 540 mm) and 5 L stainless-steel reservoir support benchtop integration without sacrificing flow capacity or thermal inertia.

Key Features

• Non-cycling refrigeration architecture with adaptive PID control—minimizes thermal overshoot and stabilizes load temperature faster than conventional on/off compressors.
• Integrated digital display showing real-time values for temperature, circulation pressure, and reservoir level—no external sensors or add-on modules required.
• High-efficiency air-cooled condenser with low-noise axial fans, rated for continuous operation under ambient conditions up to 35 °C.
• Industrial-grade circulation pump delivering up to 15 L/min at 0.8 bar, with NPT 1/2″ inlet/outlet ports compatible with standard laboratory tubing and quick-connect fittings.
• Corrosion-resistant 304 stainless-steel reservoir with 40 mm fill port and level sensor—designed for compatibility with deionized water, water-glycol mixtures (up to 30%), and other non-aggressive coolants.
• Compressor and critical thermal components sourced from globally recognized OEM suppliers—ensuring long-term reliability and serviceability under sustained duty cycles.

Sample Compatibility & Compliance

The LX-600 is designed to interface with a broad spectrum of laboratory instrumentation—including spectrophotometers, mass spectrometers, electrophoresis systems, vacuum pumps, and analytical calorimeters—that require externally regulated coolant flow. Its pressure and flow characteristics meet the inlet specifications of most major OEM instruments (e.g., Thermo Fisher, Agilent, Shimadzu, PerkinElmer). While the chiller itself does not carry CE, UL, or FDA certification, its electrical design complies with IEC 61010-1 safety standards for laboratory equipment. When deployed in GLP- or GMP-regulated workflows, users may configure audit trails via optional RS485 or analog 0–10 V output interfaces (available upon request) to support 21 CFR Part 11–compliant data logging when paired with validated third-party software platforms.

Software & Data Management

The LX-600 operates as a standalone instrument with no embedded firmware-based data logging or network connectivity. All control and monitoring are performed locally via its front-panel LCD and tactile keypad. For integration into centralized lab infrastructure, optional analog voltage (0–10 V) and digital RS485 Modbus RTU outputs enable connection to SCADA systems, PLCs, or custom LabVIEW/Python-based acquisition frameworks. These interfaces allow remote readout of temperature setpoint, actual bath temperature, pump status, and reservoir level—but do not support remote parameter adjustment or firmware updates. No proprietary software or cloud platform is required or provided; configuration remains hardware-centric to maximize operational simplicity and cybersecurity resilience.

Applications

• Stabilization of optical benches and interferometric measurement systems sensitive to thermal expansion.
• Cooling of high-power LED light sources and laser diodes in fluorescence microscopy and Raman spectroscopy setups.
• Temperature regulation of HPLC column ovens and detector cells to improve retention time reproducibility and peak resolution.
• Heat dissipation for vacuum diffusion pumps and rotary evaporator condensers operating under high-load vacuum conditions.
• Support of controlled-environment sample preparation stations where ambient fluctuations must be decoupled from process-critical thermal zones.

FAQ

What is the maximum allowable coolant viscosity for use with the LX-600?
The circulation pump is rated for aqueous solutions and water-glycol mixtures with kinematic viscosity ≤ 5 cSt at operating temperature. Higher-viscosity fluids (e.g., silicone oils) are not supported and may cause premature pump wear or flow instability.
Can the LX-600 maintain 5 °C in a 35 °C ambient environment?
Yes—the unit is thermally rated for full refrigeration capacity (600 W) at ambient temperatures up to 35 °C, provided adequate ventilation (≥ 150 mm clearance on all sides) and unobstructed airflow around the rear condenser grille.
Is the reservoir volume sufficient for overnight unattended operation?
With typical flow rates of 8–12 L/min and standard heat loads (8 hours without topping up—assuming no significant evaporation or leakage and use of sealed-loop configurations.
Does the LX-600 include dry-run protection for the circulation pump?
Yes—a float-level switch disables pump operation when reservoir volume falls below 1.2 L, preventing cavitation and mechanical damage.
Are replacement filters or maintenance kits available?
Coolium supplies OEM-certified filter cartridges (part #CF-LX600-FIL) and service kits containing O-rings, gaskets, and desiccant for annual preventive maintenance—available through authorized distributors with traceable lot documentation.
