XUEKE IMS-150 Standalone High-Efficiency Fluorine-Free Flake Ice Machine

Overview

The XUEKE IMS-150 is a standalone, fluorine-free flake ice machine engineered specifically for demanding laboratory environments where consistent, hygienic, and temperature-stable cooling media are critical. Unlike conventional cube or tube ice generators, the IMS-150 employs a direct-expansion evaporator drum system in which water is evenly distributed over a refrigerated stainless-steel surface. As the drum rotates, thin layers of water freeze rapidly and are scraped off by precision-ground stainless augers—producing dry, irregular, low-density flake ice with high surface-area-to-volume ratio. This morphology ensures rapid thermal transfer, minimal meltwater retention, and compatibility with sensitive sample handling protocols. The unit utilizes an environmentally compliant refrigeration circuit compatible with next-generation low-GWP refrigerants (e.g., R290, R1234ze, or R513A), eliminating ozone-depleting substances and aligning with EU F-Gas Regulation and China’s HCFC Phase-Out Program. Its air-cooled condenser eliminates dependency on external water sources for heat rejection—making it suitable for installation in confined lab spaces, mobile labs, or facilities with limited plumbing infrastructure.

Key Features

• Fluorine-free refrigeration architecture compliant with international environmental standards and laboratory sustainability requirements
• Microprocessor-controlled automation with real-time status monitoring: ice-full detection, low-water alarm, and self-diagnostic fault codes displayed via LED interface
• Food-grade AISI 304 stainless steel construction throughout ice-making chamber, storage bin, and exterior housing—ensuring corrosion resistance, cleanability, and compliance with ISO 8573-1 (compressed air purity) and NSF/ANSI 12 for food equipment
• Optimized flake geometry: average particle size <1.5 mm thickness, irregular shape, and low residual moisture (<3%)—ideal for tissue preservation, enzymatic reaction quenching, and cold-chain sample transport
• No external drain required; integrated condensate management system recirculates and reuses condensate for enhanced water efficiency
• Quiet operation (<62 dB(A) at 1 m) achieved through vibration-dampened compressor mounting and aerodynamically tuned fan assembly—critical for noise-sensitive analytical lab zones

Sample Compatibility & Compliance

The IMS-150 delivers ice that meets the functional requirements of GLP- and GMP-regulated workflows involving biological specimens, clinical samples, and temperature-sensitive reagents. Its flake output is validated for use in cryopreservation staging, histology specimen embedding, PCR setup cooling, and chromatography column temperature stabilization. All wetted surfaces conform to USP Class VI biocompatibility testing criteria. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge and RF fields), ensuring electromagnetic compatibility in proximity to sensitive instrumentation such as NMR spectrometers, mass spectrometers, and electrophoresis systems. Electrical safety conforms to IEC 61010-1 for laboratory equipment.

Software & Data Management

While the IMS-150 operates as a dedicated hardware appliance without cloud connectivity, its embedded controller supports audit-ready data logging: cycle start/end timestamps, cumulative operating hours, ice production volume per 24-h period, and event-triggered alarms (e.g., “low water detected at 2024-06-12T08:42:17Z”). Logs are exportable via USB interface in CSV format for integration into LIMS or quality documentation systems. Optional RS-485 Modbus RTU output enables centralized monitoring within facility-wide building management systems (BMS), supporting FDA 21 CFR Part 11–aligned electronic record integrity when paired with validated third-party SCADA platforms.

Applications

• Pre-analytical sample cooling in clinical laboratories (e.g., whole blood separation, serum/plasma stabilization prior to centrifugation)
• Temperature control during electrophoresis gel casting and running procedures
• Cooling bath medium for low-temperature chemical synthesis and catalyst handling
• Biological specimen transport between collection sites and core labs under validated cold-chain conditions
• Supporting ISO/IEC 17025-accredited calibration labs requiring traceable, repeatable thermal mass for instrument stability verification

FAQ

Does the IMS-150 require a dedicated water line or plumbing connection?

No—it operates with a standard 10-L removable water reservoir and does not require permanent plumbing. Optional continuous-feed kits are available for high-throughput installations.
Can the flake ice be stored long-term in the built-in bin without compaction or melting?

The insulated 50-kg storage bin maintains internal temperatures ≤−5 °C under ambient conditions up to 32 °C, minimizing bridging and melt-refreeze cycles for up to 12 h of standby retention.
Is the unit certified for use in ISO Class 5 cleanrooms?

While not classified as a cleanroom-grade device, its sealed refrigeration loop, zero oil carryover design, and non-shedding stainless components meet prerequisite requirements for ancillary support equipment in controlled environments when installed with appropriate HEPA-filtered air intake.
What maintenance intervals are recommended for laboratory-grade reliability?

Daily visual inspection of water level and ice quality; quarterly descaling using citric acid-based solution; annual compressor oil and filter check per manufacturer service bulletin XUEKE-IMS-150-MNT-REV3.
