Coolium FM50 Flake Ice Maker

Overview

The Coolium FM50 Flake Ice Maker is an air-cooled, laboratory-optimized flake ice generation system engineered for precision thermal management in analytical, biological, and pharmaceutical workflows. Unlike cubed or nugget ice machines, the FM50 employs a dual-screw extrusion principle—where chilled evaporator surfaces freeze a thin water film, followed by mechanical shearing via counter-rotating stainless-steel screws—to produce small, irregular, low-density flake ice (typically 1–3 mm in maximum dimension). This morphology delivers exceptional thermal transfer efficiency due to high surface area and interstitial void fraction, enabling rapid, uniform cooling of centrifuge rotors, electrophoresis tanks, enzymatic reaction vessels, and sample preparation stations. Designed specifically for controlled environments, the unit operates continuously under ambient temperatures up to 32 °C and maintains stable output without external chiller integration.

Key Features

• Compact footprint (500 × 570 × 800 mm) minimizes benchtop or under-bench spatial demand—ideal for ISO Class 5–7 cleanrooms and modular lab layouts.
• Five-stage planetary gear reduction ensures smooth, low-noise operation (<58 dB[A] at 1 m), critical for noise-sensitive environments such as core facilities and imaging suites.
• Hermetically sealed, imported rotary compressor with R134a refrigerant circuit provides consistent evaporator surface temperature control (−10 to −15 °C), enabling reproducible flake formation across varying inlet water temperatures (5–30 °C).
• Stainless-steel 304 housing and food-grade ice contact surfaces comply with NSF/ANSI 12 standards for incidental food contact; non-porous finish resists microbial adhesion and facilitates routine disinfection per CLSI GP26-A4 guidelines.
• Microprocessor-based controller monitors condenser airflow, compressor cycle time, ice thickness sensor feedback, and reservoir level—triggering automatic shutdown during low-water or high-head-pressure conditions.
• Auto-recovery logic resumes operation from last known state following transient power interruption or temporary water supply loss—eliminating manual reset and preserving process continuity.

Sample Compatibility & Compliance

The FM50 produces flake ice suitable for direct contact with biological samples, reagent containers, and temperature-sensitive instrumentation. Its ice morphology prevents localized freezing or mechanical damage associated with sharp-edged cubes, making it appropriate for cryopreservation support, cold-chain validation studies, and QC sample stabilization. The unit meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage safety (EN 61000-6-3). While not classified as medical device under EU MDR or FDA 21 CFR Part 820, its design aligns with GLP-compliant infrastructure expectations—including traceable operational logs (via optional RS485 interface), ELCB-certified electrical isolation, and documented maintenance intervals per ISO/IEC 17025 Clause 6.4.2.

Software & Data Management

The embedded controller supports local status display (LED panel) showing real-time ice production rate, compressor runtime, and fault codes (e.g., E01 = low water, E03 = high discharge temp). Optional Modbus RTU communication enables integration into centralized building management systems (BMS) or LIMS for audit-trail-capable logging of uptime, energy consumption (kWh/day), and maintenance alerts. Firmware updates are performed via USB port using vendor-provided configuration tools—ensuring version control and compliance with internal IT security policies.

Applications

• Pre-chilling of HPLC mobile phase solvents and autosampler trays prior to injection.
• Maintaining sub-10 °C environment in gel electrophoresis buffer tanks during extended runs.
• Rapid thermal quenching of enzymatic reactions in kinetic assay development.
• Supporting cold storage logistics during biobank specimen aliquoting and transport staging.
• Calibration verification of digital thermometers and IR pyrometers using ice-point reference baths (per ASTM E74-22 Annex A1).
• Providing consistent thermal mass for calorimetry blank runs and heat capacity standardization.

FAQ

What is the recommended water quality for optimal flake ice clarity and system longevity?
Deionized or reverse-osmosis treated water (conductivity <10 µS/cm) is strongly advised to prevent scale buildup on evaporator surfaces and reduce maintenance frequency. Municipal tap water may be used if hardness is below 100 ppm CaCO₃ equivalent.
Does the FM50 require a dedicated drainage line?
Yes—condensate and meltwater must be routed to a floor drain or collection vessel via the integrated 12-mm ID outlet hose; no internal pump is included.
Can the FM50 operate unattended overnight?
Yes—the microcontroller includes overheat, overcurrent, and low-water cutouts; however, periodic visual inspection of ice bin fill level is recommended to avoid overflow-related spillage.
Is remote monitoring supported out-of-the-box?
Basic status indicators are local only; RS485 Modbus interface is available as a factory-installed option (Coolium Part No. FM50-MODBUS-KIT).
What is the expected service interval for compressor oil and filter replacement?
Under continuous laboratory use (16 h/day), scheduled maintenance—including refrigerant pressure verification, condenser coil cleaning, and drive gear lubrication—is required every 12 months, per Coolium Maintenance Manual Rev. 3.2.
