Coolium LX-1000 Circulating Chiller

Overview

The Coolium LX-1000 Circulating Chiller is an integrated, air-cooled refrigeration system engineered for precision temperature control and stable heat removal in laboratory and industrial applications. It employs a vapor-compression refrigeration cycle—using a hermetically sealed compressor, copper-aluminum finned condenser, and expansion valve—to transfer thermal energy from process fluid to ambient air. The chiller circulates deionized water or aqueous glycol solutions through external equipment via a high-efficiency centrifugal pump, maintaining setpoint temperatures with minimal deviation over extended operation. Designed for continuous-duty use, the LX-1000 delivers consistent 1000 W cooling capacity at 20 °C ambient and supports closed-loop thermal management for sensitive instrumentation requiring tight thermal regulation between 5 °C and 35 °C.

Key Features

• High-stability temperature control with ±0.1 °C setpoint accuracy and real-time digital display of temperature, pressure, and reservoir level
• Dynamically tuned PID-based temperature controller with auto-tuning capability and parameter retention after power interruption
• Modular pump assembly offering selectable configurations: standard, high-pressure (up to 3.7 bar), high-flow (up to 28 L/min), or ultra-low-noise variants
• Corrosion-resistant stainless steel fluid path components—including inlet/outlet ports (Rc1/2″ female), reservoir liner, and internal piping—to ensure compatibility with deionized water and low-conductivity coolants
• Internationally sourced critical refrigeration components (compressor, expansion valve, and condenser fan) for long-term operational reliability and reduced maintenance frequency
• Adjustable circulation pressure with calibrated stainless steel pressure gauge and fine-tuned flow regulation via integrated bypass valve
• Optional upgrades include 0.01 °C resolution temperature sensing, flow rate monitoring with alarm output, and RS485 Modbus RTU interface for SCADA integration and remote supervision

Sample Compatibility & Compliance

The LX-1000 is compatible with a broad range of process fluids, including deionized water (resistivity ≥ 1 MΩ·cm), 10–30% ethylene glycol/water mixtures, and other non-corrosive, low-viscosity coolants meeting ASTM D1121 or ISO 2592 specifications. Its sealed reservoir and inert wetted materials prevent microbial growth and particulate generation—critical for applications requiring ISO Class 5–7 cleanroom-compatible thermal management. While not certified as medical device (FDA 21 CFR Part 820) or IEC 61000-6-3 compliant out-of-box, the unit meets CE marking requirements for EMC and LVD (2014/30/EU and 2014/35/EU). For GxP environments, optional audit-trail-enabled firmware (with timestamped event logging and user-access controls) supports alignment with GLP and GMP documentation practices per Annex 11 and USP .

Software & Data Management

The LX-1000 operates autonomously via its embedded microcontroller and front-panel HMI, supporting manual setpoint adjustment, alarm acknowledgment, and status diagnostics without external software. When equipped with the RS485 Modbus RTU option, it integrates seamlessly into LabVIEW, MATLAB, or custom SCADA platforms using standard function codes (e.g., FC3 for register read, FC6 for single-register write). Communication enables remote configuration of temperature setpoints, pump speed, alarm thresholds, and real-time acquisition of temperature, pressure, flow (if installed), and compressor run-time. All data points are timestamped and can be logged to CSV or database formats; optional firmware supports configurable data sampling intervals (1–60 s) and cyclic buffer storage for up to 72 hours of operational history.

Applications

• Analytical instrumentation: Thermal stabilization of ICP-OES, AAS, XRD, NMR spectrometers, and mass spectrometer ion sources where thermal drift directly impacts spectral resolution and signal-to-noise ratio
• Vacuum & photonics systems: Active cooling of sputtering targets, cryopumps, RF amplifiers, diode-pumped solid-state lasers, and electron microscope column assemblies
• Bioprocessing & pharmaceutical R&D: Jacket temperature control for lab-scale bioreactors (≤5 L), freeze-dryer condenser plates, and calorimetric reaction vessels under cGMP-aligned workflows
• Precision manufacturing: CNC spindle thermal management, EDM dielectric fluid conditioning, and laser cutting head cooling to maintain dimensional repeatability
• Medical & advanced research infrastructure: MRI gradient coil thermal regulation, proton therapy beamline component cooling, and hydrogen fuel cell test station thermal load balancing
• Materials science platforms: Support for plasma etch chambers, glovebox atmosphere conditioning, high-frequency induction furnaces, and synchrotron beamline optics cooling loops

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The LX-1000 is rated for continuous operation at ambient temperatures up to 35 °C. Performance derating begins above this threshold; full 1000 W capacity is guaranteed only at ≤30 °C ambient with adequate ventilation (≥300 mm clearance on all sides).

Can the chiller operate with pure water in hard-water regions?
No. Use of untreated tap water may cause scale formation and corrosion. Deionized water (≥1 MΩ·cm) or inhibited glycol solutions are required. Optional inline deionization cartridges and anti-scale filters are available as accessories.

Is the reservoir volume sufficient for large-volume external circuits?
The 8 L reservoir is optimized for dynamic response in typical lab-scale circuits (<15 m tubing length, <5 L external volume). For larger systems, external expansion tanks or secondary reservoirs can be integrated via the Rc1/2″ ports.

Does the unit support dual-temperature zone control?
No. The LX-1000 provides single-zone temperature control. Dual-loop or multi-zone thermal management requires parallel units or higher-tier models with independent circuit control.

What safety protections are built into the system?
Standard safeguards include high-temperature cutoff (≥45 °C), low-level reservoir shutoff, overpressure relief (4.0 bar), compressor current overload protection, and phase-loss detection for three-phase variants (not applicable to standard 220 V model).
