Coolium LX-10K Industrial Circulating Chiller

Overview

The Coolium LX-10K is an integrated, air-cooled industrial circulating chiller engineered for high-demand laboratory and pilot-scale applications requiring simultaneous high cooling capacity and tight temperature regulation. It operates on a vapor-compression refrigeration cycle with R410A or R134a refrigerant (model-dependent), delivering stable thermal management across a precisely controlled range of 8–25 °C. Its core function is to maintain constant coolant temperature and pressure while circulating deionized or treated water through external equipment—such as electron microscopes, vacuum deposition systems, ion beam sources, and high-power laser platforms—where thermal drift directly impacts measurement fidelity, process repeatability, or component longevity. Unlike benchtop chillers, the LX-10K features a robust structural frame, industrial-grade hermetic scroll compressor, and oversized condenser coils optimized for continuous operation under ambient temperatures up to 40 °C. Its design prioritizes thermal inertia minimization, low-pressure drop fluid pathways, and long-term reliability in 24/7 environments typical of research facilities and GMP-aligned manufacturing support labs.

Key Features

• High-capacity refrigeration system delivering 10 kW at 20 °C ambient, scalable within the LX-K series (10–100 kW) for modular infrastructure planning
• Dual-window, dual-color digital temperature controller with PID algorithm tuning, achieving ±0.2 °C stability over full operating range
• Integrated non-paper data logger with timestamped storage of setpoint, actual temperature, flow rate, and compressor runtime; data exportable via USB or RS485 interface
• Optional built-in deionization module with real-time conductivity monitoring (range: 0.1–20 µS/cm), configurable alarm thresholds and auto-regeneration cycles
• Comprehensive safety architecture including high/low pressure cutouts, phase sequence detection, motor overload protection, reservoir level sensor, and dry-run prevention logic
• Stainless steel reservoir (304 grade) with integrated sediment trap, anti-corrosion coating on internal piping, and leak-tight DN25 BSP female threaded ports compliant with ISO 228-1

Sample Compatibility & Compliance

The LX-10K is designed for closed-loop circulation of purified water, glycol-water mixtures (up to 30% v/v), or other low-viscosity, non-aggressive coolants compatible with stainless steel 304 and EPDM elastomer seals. It meets CE marking requirements per EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions). Electrical safety complies with IEC 61000-1-2 and IEC 60335-1. While not certified to UL 61010-1 out-of-box, it supports third-party listing when installed per manufacturer-specified ventilation clearances (min. 500 mm rear/side, 1000 mm top). The unit’s control firmware supports audit trail logging and user-access levels—enabling alignment with GLP and FDA 21 CFR Part 11 principles when deployed in regulated environments (e.g., pharmaceutical analytical instrument cooling, semiconductor metrology tool support).

Software & Data Management

The LX-10K includes embedded firmware with Modbus RTU (RS485) and optional Ethernet/IP communication protocols. Standard software suite provides remote monitoring and configuration via Windows-based Coolium ControlCenter, supporting real-time graphing, alarm history review, and export of CSV-formatted datasets. All logged parameters—including temperature deviation, cumulative pump hours, compressor start-stop cycles, and voltage fluctuations—are time-stamped with millisecond resolution and stored in non-volatile memory for ≥12 months. Firmware updates are performed via secure USB key with SHA-256 signature verification. Optional OPC UA server integration enables seamless connectivity to LabVantage, DeltaV, or Siemens Desigo CCMS platforms for centralized facility thermal management.

Applications

• Electron microscopy: Stabilizing detector and column temperatures in TEM/SEM systems to reduce thermal lensing and improve spatial resolution
• Thin-film deposition: Maintaining consistent target and substrate temperatures during magnetron sputtering and e-beam evaporation processes
• Materials testing: Supporting high-energy X-ray diffraction (XRD) and synchrotron beamline instrumentation where thermal expansion must remain sub-micron
• Plastics processing R&D: Controlling mold temperature in injection molding trials to quantify crystallinity effects on mechanical properties
• Power electronics validation: Cooling high-current test fixtures and RF amplifiers during accelerated life testing under thermal stress profiles
• Accelerator physics: Managing heat load from kicker magnets and RF cavities in compact linear accelerator test stands

FAQ

What is the maximum allowable coolant conductivity when using the optional deionization module?
The system supports conductivity down to 0.1 µS/cm; operation below 0.5 µS/cm requires periodic resin replacement and calibration of the inline sensor against NIST-traceable standards.
Can the LX-10K be integrated into a building management system (BMS)?
Yes—via Modbus RTU (standard) or BACnet MS/TP (optional firmware upgrade), enabling status reporting, setpoint adjustment, and fault annunciation through standard BMS gateways.
Is the reservoir accessible for routine maintenance without disassembly?
Yes—the top panel lifts vertically to expose the entire reservoir interior, drain valve, and filter cartridge housing; all service points are tool-accessible with standard 8 mm and 10 mm wrenches.
What is the expected mean time between failures (MTBF) for the primary circulation pump?
Based on ISO 13374-2 vibration analysis and field telemetry from 2021–2023 deployments, MTBF exceeds 32,000 hours under continuous operation at rated flow and 25 °C ambient.
Does the unit comply with RoHS and REACH directives?
Yes—full material declarations and SVHC screening reports are available upon request; all PCBs, wiring harnesses, and refrigerant charge are RoHS 2011/65/EU and REACH Annex XIV compliant.
