Overview
The DELEITE IM-20 Flake Ice Machine is a compact, laboratory-grade flake ice generator engineered for consistent, on-demand production of high-purity, cylindrical ice particles under controlled ambient conditions. Utilizing dual-screw extrusion technology, the unit forces water through a precisely machined freezing cylinder where rapid heat exchange with R134a refrigerant induces nucleation and solidification. The resulting flake ice exhibits uniform geometry (cylindrical morphology), high optical clarity, and low surface moisture—properties critical for applications requiring minimal thermal shock, reproducible cooling kinetics, and avoidance of meltwater dilution. Designed for continuous operation in analytical laboratories, QC environments, and biomedical sample preparation areas, the IM-20 integrates seamlessly into workflows demanding reliable cold-chain support without external glycol loops or chilled water infrastructure.
Key Features
- Stainless steel 304 enclosure with electropolished interior surfaces—resistant to corrosion, compliant with ISO 14644-1 Class 8 cleanroom-compatible handling protocols.
- Microprocessor-based control system with real-time monitoring of evaporator temperature, compressor cycle status, and water feed pressure—enabling programmable start/stop scheduling and fault diagnostics.
- Dual-screw extrusion mechanism ensures mechanical consistency across ice batches; eliminates reliance on ambient humidity or water mineral content for shape fidelity.
- Automatic safety interlocks: ice bin full detection (via capacitive level sensor) and low-water cutoff (pressure switch monitored at inlet solenoid valve) prevent dry-run operation and overfilling.
- R134a refrigeration circuit—non-ozone-depleting, ASHRAE-certified, compatible with standard service tools and EPA Section 608 technician certification requirements.
- Self-contained design with integrated condenser and air-cooled heat rejection—no external ventilation ducting required; operates within ambient range of 5–32°C.
Sample Compatibility & Compliance
The IM-20 produces flake ice suitable for direct contact with biological specimens (e.g., tissue biopsies, centrifuged serum aliquots), reagent vials, and chromatography column coolers. Its ice morphology minimizes surface area-to-volume ratio, reducing melt rate by up to 35% compared to cubed ice under identical storage conditions (per ASTM D6866-22 methodology). Unit complies with CE marking requirements per Directive 2014/35/EU (Low Voltage Directive) and 2014/30/EU (EMC Directive). Electrical insulation meets IEC 61000-4-2 (ESD immunity) and IEC 61000-4-3 (radiated RF immunity) standards. Not intended for food-grade use unless validated per local health authority requirements (e.g., NSF/ANSI 12-2023 not claimed).
Software & Data Management
The IM-20 operates via embedded firmware without external software dependency. All operational parameters—including cumulative runtime, total ice output (kg), number of automatic shutdown events, and compressor duty cycle—are logged in non-volatile memory with timestamp resolution of ±1 minute. Audit trail data is accessible via USB-C port using proprietary diagnostic utility (Windows/macOS compatible); logs export as CSV files with ISO 8601 timestamps. Firmware supports remote firmware updates via secure signed binary protocol, maintaining integrity per NIST SP 800-193 guidelines. No network connectivity or cloud integration is implemented—ensuring air-gapped operation for GLP/GMP-regulated labs requiring strict data sovereignty.
Applications
- Cooling of enzymatic reaction mixtures during PCR setup and restriction digest protocols.
- Temperature stabilization of HPLC autosampler trays and detector flow cells.
- Pre-chilling of centrifuge rotors and microcentrifuge tubes prior to high-speed runs.
- Transport conditioning of clinical specimens (e.g., CSF, synovial fluid) between collection and analysis sites.
- Calibration verification of thermocouple probes and IR thermometers using ice-point reference (0.00 °C ±0.05 °C under stabilized conditions).
- Supporting cryo-microtome sectioning workflows where rapid, localized surface cooling prevents thermal artifact formation.
FAQ
What is the recommended water quality specification for optimal ice clarity and system longevity?
Deionized or reverse-osmosis treated water (conductivity 100 ppm CaCO₃ may accelerate scaling in the freezing cylinder and reduce thermal transfer efficiency.
Does the IM-20 support continuous ice dispensing into external containers?
Yes—equipped with gravity-fed discharge chute and adjustable deflector plate; compatible with standard 5-L polypropylene ice buckets and stainless steel transport bins.
Is routine maintenance required beyond daily drain and wipe-down?
Quarterly descaling using citric acid solution (5% w/v, 40°C, 30-min dwell time) is advised; annual inspection of condenser coil cleanliness and refrigerant charge verification by certified technician.
Can the unit be installed in a ventilated cabinet or enclosed bench space?
Minimum 15 cm clearance required on all sides and top; rear exhaust must remain unobstructed to maintain condenser airflow velocity ≥1.2 m/s per ASHRAE Handbook—HVAC Applications Chapter 47.
What documentation is provided for regulatory audits?
CE Declaration of Conformity, electrical safety test report (EN 61000-6-3), refrigerant charge label (R134a mass + GWP value), and factory calibration certificate for ice-point stability (measured at 0.00 °C ±0.03 °C, traceable to NIM, Beijing).
