Coolium LX-15K Industrial Circulating Chiller

Overview

The Coolium LX-15K is an integrated, air-cooled industrial circulating chiller engineered for stable, high-capacity thermal management in demanding laboratory and pilot-scale instrumentation environments. Utilizing a hermetically sealed scroll compressor, high-efficiency finned-tube condenser, and precision expansion valve control, the system delivers consistent refrigeration performance across its operational range of 8–25°C. Its core thermodynamic architecture follows vapor-compression cycle principles optimized for low-temperature stability and minimal thermal drift—critical for applications requiring long-duration, unattended operation. Unlike compact benchtop chillers, the LX-15K features a reinforced structural frame, industrial-grade insulation, and a large-volume 60 L stainless-steel reservoir to dampen thermal transients and support extended flow continuity. Designed for integration with high-heat-load instruments—including transmission electron microscopes (TEM), focused ion beam (FIB) systems, RF sputtering sources, high-vacuum diffusion pumps, and particle accelerator beamline cooling loops—the LX-15K maintains temperature uniformity within ±0.2°C under full-load conditions, verified per ISO 17025 traceable calibration protocols.

Key Features

• High-stability dual-display PID controller with independent setpoint and real-time bath temperature readouts, enabling rapid response to load fluctuations
• Multi-stage safety interlock system: high/low pressure cut-off, phase sequence monitoring, overcurrent protection, low-level reservoir alarm, and dry-run prevention for pump longevity
• Industrial-grade centrifugal circulation pump rated for continuous duty at up to 3.8 bar maximum head pressure and variable flow output (17–117 L/min)
• Corrosion-resistant 304 stainless steel reservoir with sight gauge, drain valve, and optional deionized water filtration module (Coolium DI-Kit, sold separately)
• Modular heat exchanger assembly with enhanced surface area and low-fouling internal geometry to sustain thermal efficiency over extended service intervals
• Front-access service panel with labeled terminal blocks, refrigerant service ports, and pump motor inspection window for simplified maintenance

Sample Compatibility & Compliance

The LX-15K is designed for closed-loop cooling of non-corrosive, low-viscosity aqueous or glycol-water mixtures (up to 30% ethylene glycol). It meets mechanical and electrical safety expectations aligned with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) standards. While not certified as medical or explosion-proof equipment, its construction complies with general-purpose industrial equipment directives applicable to laboratory infrastructure (e.g., EN 61000 series, UL 61010-1). The unit supports audit-ready operation in regulated environments: temperature logs can be exported via RS485 interface, and optional data acquisition modules provide timestamped records compliant with FDA 21 CFR Part 11 requirements when paired with validated software platforms.

Software & Data Management

The LX-15K operates autonomously via its embedded microcontroller-based control system. Optional connectivity includes Modbus RTU (RS485) for integration into centralized building management systems (BMS) or SCADA networks. When interfaced with Coolium’s ChillerLink™ Lab Suite (v3.2+), users gain access to remote parameter adjustment, historical trend visualization, alarm event logging with UTC timestamps, and automated report generation (CSV/PDF). All temperature and pressure data are stored locally with battery-backed memory retention (>72 hours power loss resilience). Audit trails include operator ID (if network-authenticated), parameter change history, and system fault codes—all exportable for GLP documentation and internal QA review.

Applications

• Stabilization of electron optical columns in TEM/SEM/FIB systems where thermal lensing must remain below 50 nm focal shift over 8-hour imaging sessions
• Cooling of high-power RF magnetrons and DC sputter targets during thin-film deposition processes requiring <±0.3°C bath stability
• Thermal regulation of vacuum chamber jackets in molecular beam epitaxy (MBE) and pulsed laser deposition (PLD) tools
• Heat extraction from superconducting magnet cryocooler cold heads and accelerator cavity couplers
• Support of laser-based analytical systems (e.g., LIBS, ICP-MS auxiliary chillers) where coolant temperature directly impacts spectral resolution
• Process cooling in pilot-scale chemical reactors and calorimetry rigs operating under ISO/IEC 17025-accredited test methods

FAQ

What is the recommended coolant composition for optimal performance?
Deionized water is preferred for maximum heat transfer efficiency and minimal scaling risk. For sub-ambient operation or freeze protection, a mixture of ≤30% USP-grade ethylene glycol in DI water is acceptable—but requires recalibration of flow sensors and may reduce effective cooling capacity by ~8–12%.
Can the LX-15K be integrated into a facility-wide chilled water network?
No—it is a self-contained, primary-loop chiller. It is not designed for secondary-loop or building chilled water return integration. However, it can serve as a dedicated subsystem for isolated high-value instrumentation.
Is remote monitoring supported out-of-the-box?
Basic status indicators (run/fault/temperature) are visible on the front panel display. Full remote telemetry requires the optional RS485 communication module and third-party or Coolium-supplied SCADA-compatible software.
What maintenance schedule is recommended for uninterrupted operation?
Compressor oil and refrigerant charge verification every 24 months; condenser coil cleaning every 6 months in dust-prone environments; pump impeller inspection and seal replacement every 48 months under continuous operation.
Does the unit comply with noise emission limits for ISO Class 5 cleanroom peripheries?
At 1 m distance, sound pressure level is 68 dB(A) under full load—within acceptable limits for equipment rooms adjacent to controlled environments, though not suitable for direct placement inside cleanroom spaces.
