Overview
The Hanuo HN100 Commercial Flake Ice Machine is an air-cooled, self-contained flake ice generator engineered for consistent, low-maintenance operation in laboratory, clinical, and quality control environments. Unlike traditional cube or nugget ice systems, the HN100 employs a dual-screw extrusion principle—where chilled refrigerant circulates through a vertically oriented evaporator drum, freezing a thin film of water that is continuously scraped off by rotating augers. This process yields dry, irregularly shaped flake ice with high surface-area-to-volume ratio, rapid thermal transfer characteristics, and minimal meltwater retention—critical attributes for sample cooling, biological specimen preservation, chromatography column temperature stabilization, and cold-chain validation protocols. Designed to operate continuously under ambient temperatures up to 32 °C, the unit complies with IEC 61000-6-3 (EMC emissions) and meets CE safety requirements for electrical appliances used in non-explosive atmospheres.
Key Features
- Dual-screw extrusion system ensures uniform flake morphology and eliminates ice bridging or clumping in the storage bin.
- Air-cooled condensing unit with high-efficiency rotary compressor—no external water hook-up or drain required; suitable for ISO Class 7 cleanroom-adjacent installations.
- Full microprocessor control with LCD interface: programmable start/stop cycles, real-time ice level monitoring, automatic defrost scheduling, and fault-code diagnostics (e.g., high head pressure, low refrigerant flow).
- Stainless steel evaporator drum (AISI 304) and food-grade HDPE ice bin—compliant with NSF/ANSI 12 standards for indirect food contact surfaces.
- Low acoustic output (<62 dB(A) at 1 m), enabling placement in shared lab corridors or near analytical instrumentation without vibration coupling.
- Integrated thermal cut-off and phase-loss protection meet EN 60335-1 general safety requirements for laboratory refrigeration equipment.
Sample Compatibility & Compliance
The HN100 produces flake ice with nominal thickness of 1.0–2.2 mm and lateral dimensions ranging from 8–15 mm—ideal for packing electrophoresis gels, chilling centrifuge rotors pre-run, tempering cryogenic solvents, and maintaining cold plates during calorimetry calibration. Ice output is stable across input water conductivity ≤500 µS/cm; optional integrated sediment filter (not included) recommended for municipal feed water with >10 ppm total dissolved solids. The system supports GLP-compliant operation when paired with external data loggers recording ambient temperature, runtime hours, and ice bin fill status. While not certified to UL 450 or FDA 21 CFR Part 11 out-of-the-box, its firmware architecture permits audit-trail-enabled integration via RS485 Modbus RTU protocol.
Software & Data Management
The HN100 operates autonomously without embedded software dependencies. All operational parameters—including compressor run time, defrost interval count, and daily ice yield estimates—are stored locally in non-volatile EEPROM memory for retrieval via front-panel navigation. For centralized lab infrastructure monitoring, the unit supports optional serial communication modules (Hanuo Part No. HN-RS485-KIT) enabling integration into LabVantage, STARLIMS, or custom SCADA dashboards. Raw timestamped logs (CSV format) can be exported for trend analysis of ice production efficiency relative to ambient humidity and supply voltage variance—supporting ISO/IEC 17025 clause 5.9 on equipment performance verification.
Applications
- Cooling of PCR thermal cyclers and DNA sequencers during extended sequencing runs.
- Pre-chilling of HPLC mobile phase reservoirs to reduce baseline drift in low-temperature gradient methods.
- Temperature stabilization of NMR probe heads during shimming procedures.
- Short-term preservation of tissue biopsies prior to flash-freezing in liquid nitrogen.
- Calibration verification of infrared thermometers using ice-point reference baths (per ASTM E1137/E1137M).
- Supporting ISO 15189-accredited clinical labs requiring documented cold chain integrity for transport validation studies.
FAQ
What is the typical flake ice density and melting rate at 25 °C ambient?
Flake ice produced by the HN100 has a bulk density of approximately 350–420 kg/m³ and exhibits a surface melt rate of ~0.8–1.2 kg/h when exposed to still air at 25 °C and 60% RH.
Can the HN100 be installed in a temperature-controlled cold room?
Yes—operational range is specified for ambient conditions between 5 °C and 32 °C; however, condenser airflow must remain unobstructed, and intake air should be free of particulate contamination above ISO Class 8 limits.
Is remote monitoring capability built-in or requires add-on hardware?
Remote monitoring is not native; it requires installation of the optional HN-RS485-KIT module and configuration of third-party SCADA or LIMS middleware.
Does the unit require periodic descaling if fed with softened water?
No—softened water (≤50 ppm CaCO₃ equivalent) eliminates scale formation; routine cleaning of the evaporator drum every 6 months with citric acid solution is sufficient per maintenance schedule.
What safety certifications does the HN100 hold for use in EU laboratories?
It carries CE marking per Directive 2014/35/EU (Low Voltage Directive) and 2014/30/EU (EMC Directive); full conformity assessment documentation available upon request from Hanuo Technical Support.
