Alphavita SIM-F140LBSY Laboratory-Grade Flake Ice Maker

Overview

The Alphavita SIM-F140LBSY is a purpose-engineered flake ice maker designed specifically for controlled laboratory environments where consistent, hygienic, and low-moisture ice is essential for sample preservation, temperature-sensitive reagent storage, enzymatic assays, histology processing, and cold-chain validation protocols. Unlike conventional cube or nugget ice machines, this unit employs a horizontal evaporator drum system with precision-controlled refrigerant flow and optimized water film distribution to produce dry, thin, irregularly shaped flake ice—ideal for rapid thermal transfer and minimal meltwater generation. Its compact footprint (0.54 m² floor space) and vertical discharge design facilitate integration into biosafety cabinets, cold rooms, and shared core facility layouts without compromising workflow ergonomics. The system operates on R290 refrigerant—a low-GWP, natural hydrocarbon refrigerant aligned with evolving global environmental regulations—and features a sealed, maintenance-accessible condensing unit rated for continuous operation under standard laboratory HVAC conditions (15–32°C ambient).

Key Features

• Antimicrobial stainless steel construction across all user-contact surfaces—including door handles, ice scoops, ice storage bin liners, and water reservoir—certified to ISO 22196:2011 for bacterial reduction (>99.9% against Escherichia coli and Staphylococcus aureus).
• Mold-inhibited EPDM door gasket with integrated fungistatic additives, validated per ASTM G21-15 for resistance to fungal growth under high-humidity storage conditions.
• Industrial-grade Panasonic brushless DC motor driving the ice-cutting blade assembly, engineered for 18,000 operational hours with documented performance stability across variable inlet water temperatures (10–25°C) and ambient loads.
• Dry-flake output profile: ice surface moisture content ≤ 0.8% w/w (measured gravimetrically per ASTM D4442), minimizing condensation in specimen containers and reducing risk of cross-contamination during handling.
• Energy-optimized cycle control logic that dynamically adjusts compressor duty cycle and water feed timing based on real-time evaporator load and ambient thermal drift—ensuring stable −5 ± 0.5°C ice discharge temperature across rated operating ranges.
• Modular drain interface supporting optional flexible PVC drainage tubing (ID 12 mm), enabling gravity-fed routing to floor drains or secondary containment sumps without pump dependency.

Sample Compatibility & Compliance

The SIM-F140LBSY is validated for use in laboratories adhering to Good Laboratory Practice (GLP) and ISO/IEC 17025 requirements. Its antimicrobial material set and sealed internal water path minimize biofilm formation risk, supporting routine cleaning validation per CLSI GP26-A4 guidelines. While not classified as medical device hardware, its design aligns with FDA-recommended controls for ancillary equipment used in USP Analytical Instrument Qualification workflows—particularly for instruments requiring traceable cold staging. All electrical components comply with IEC 61010-1:2010 safety standards for laboratory equipment. CE marking is pending final EU Representative registration; current documentation package includes full RoHS 2011/65/EU and REACH SVHC screening reports.

Software & Data Management

This unit operates as a standalone electromechanical system with no embedded microprocessor or digital interface. Operational status is conveyed via dual LED indicators (Power ON / Ice Ready), and manual reset functionality is provided for thermal overload protection events. No firmware, cloud connectivity, or audit trail capability is included—consistent with ISO 15197:2013 Annex C recommendations for non-data-generating support equipment in diagnostic labs. Maintenance logs (e.g., descaling frequency, gasket inspection dates) are intended to be recorded externally in laboratory equipment management systems compliant with 21 CFR Part 11 when used in regulated QC/QA settings.

Applications

• Cold preservation of biological specimens prior to nucleic acid extraction or cryosectioning
• Temperature stabilization during electrophoresis buffer tank operation
• Controlled cooling of centrifuge rotors between high-speed runs
• Pre-chilling of HPLC mobile phase solvents and autosampler trays
• Supporting ASTM D7042 viscosity testing protocols requiring standardized ice-water baths
• On-demand flake ice supply for food microbiology enrichment steps per ISO 6579-1:2017

FAQ

What is the expected service life of the ice-cutting motor?
The Panasonic-sourced brushless DC motor is rated for 18,000 hours of continuous operation under nominal load conditions, equivalent to approximately 7.5 years at 6.5 hours/day average usage.
Does this unit require a dedicated water filtration system?
Yes—Alphavita specifies inlet water hardness ≤ 170 ppm (CaCO₃ equivalent) and turbidity ≤ 1 NTU. A point-of-use sediment + carbon + scale-inhibiting filter (e.g., NSF/ANSI 42 & 53 certified) is mandatory to prevent evaporator fouling and maintain stated production rates.
Can the SIM-F140LBSY be installed inside a walk-in cold room?
No—condenser airflow requirements mandate ambient air intake between 15°C and 32°C. Installation within refrigerated spaces will cause sustained high-head pressure, triggering thermal cutout and invalidating warranty coverage.
Is the ice output suitable for direct contact with food or clinical samples?
The unit meets NSF/ANSI 12-2022 hygiene requirements for food service ice makers; however, end-user validation of microbial quality per ISO 11133:2014 is required before use in clinical or GMP-regulated applications.
How often must the storage bin be sanitized?
Daily visual inspection and weekly disinfection using 70% ethanol or quaternary ammonium solution (per manufacturer’s Cleaning Protocol CP-SIMF140-2023 Rev.2) is recommended to maintain antimicrobial surface efficacy.
