XUEKE IM-25 CE-Certified Flake Ice Machine

Overview

The XUEKE IM-25 is a compact, CE-certified flake ice machine engineered for reliable, low-maintenance ice production in controlled environments where consistent thermal management and hygiene compliance are essential. Designed specifically for laboratory, academic, and light-commercial applications—including sample cooling, reagent preservation, biological specimen transport, and benchtop temperature stabilization—the IM-25 employs a hermetically sealed R290 hydrocarbon refrigeration system, eliminating ozone-depleting substances while maintaining high thermodynamic efficiency. Unlike traditional cube or tube ice machines, the IM-25 generates dense, irregularly shaped flake ice with high surface-area-to-volume ratio and rapid thermal transfer characteristics—ideal for packing around temperature-sensitive samples without mechanical stress or condensation pooling. Its air-cooled condensing system eliminates the need for external water drainage or plumbing infrastructure, making it suitable for installation in ISO Class 5–8 cleanrooms, QC labs, and mobile analytical units where spatial constraints and utility flexibility are critical.

Key Features

• Fully automatic microprocessor-based control system with real-time status display, cycle monitoring, and self-diagnostic fault logging
• Stainless steel 304 cabinet and evaporator drum—corrosion-resistant, non-porous, and compliant with ISO 8573-1 (compressed air purity) and FDA 21 CFR Part 110 (food-grade equipment surfaces)
• R290 refrigerant compressor—low global warming potential (GWP = 3), energy-efficient (280 W nominal input), and certified to EN 60335-1 and EN 60335-2-74 safety standards
• Compact footprint (380 × 543 × 672 mm) optimized for under-bench or freestanding placement in ISO-compliant lab layouts
• Flake ice output with particle size distribution ranging from 1.5–3.0 mm thickness and 5–12 mm lateral dimensions—uniform morphology ensured by precision-machined stainless steel drum and calibrated water film thickness control
• Dual-sensor ice level detection with automatic harvest cycle termination and anti-bridging agitation to prevent ice compaction in the storage bin

Sample Compatibility & Compliance

The IM-25 produces microbiologically inert flake ice suitable for direct contact with biological specimens, pharmaceutical intermediates, and diagnostic reagents when operated with potable water meeting ASTM D1193 Type IV specifications. Its stainless steel wetted surfaces support routine sanitization using 70% ethanol or 0.5% sodium hypochlorite solutions without degradation. The unit complies with EU Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU, and RoHS Directive 2011/65/EU. CE marking documentation includes full technical file referencing EN 60335-1 (general safety), EN 60335-2-74 (particular requirements for ice makers), and EN 13486 (performance testing of refrigerated appliances). For GLP/GMP-regulated laboratories, the IM-25 supports audit-ready operation through configurable event logging (power-on, ice harvest, sensor alarms) stored in non-volatile memory.

Software & Data Management

While the IM-25 operates as a standalone appliance, its embedded controller provides RS-485 Modbus RTU interface (optional adapter required) for integration into centralized facility monitoring systems (e.g., LabVantage, Siemens Desigo, or custom SCADA platforms). Logged operational parameters—including ambient temperature, compressor run time, harvest frequency, and ice bin fill status—can be exported via USB flash drive in CSV format for trend analysis and preventive maintenance scheduling. All firmware updates are performed offline via secure encrypted firmware package verification, ensuring integrity per IEC 62443-3-3 requirements for industrial cyber security.

Applications

• Biological sample preparation: Maintaining 0–4 °C stability during DNA extraction, electrophoresis gel casting, and centrifugation protocols
• Pharmaceutical QC: Cold chain support for dissolution testing, lyophilized product handling, and reference standard storage
• Food microbiology labs: Rapid chilling of enrichment broths and agar plates prior to incubation
• University teaching labs: Demonstrating phase-change thermodynamics, heat transfer coefficients, and refrigeration cycle fundamentals
• Field-deployable analytical kits: On-site calibration of portable spectrophotometers and pH meters requiring stable thermal reference

FAQ

Is the IM-25 suitable for use in ISO 17025-accredited testing laboratories?
Yes—its documented traceable performance, CE conformity, and stainless steel construction meet the environmental control and equipment qualification requirements outlined in ISO/IEC 17025:2017 Clause 6.4.
Can the flake ice be used for direct contact with food or clinical specimens?
When fed with potable water and maintained per manufacturer cleaning schedule, the ice meets EC No. 1935/2004 requirements for food-contact materials and is routinely validated for use in CLIA-certified clinical labs.
Does the unit require a dedicated electrical circuit?
No—it operates on standard 230 V AC ±10%, 50 Hz single-phase supply with built-in overcurrent and thermal overload protection.
What is the expected service life under continuous laboratory duty?
With biannual descaling and annual compressor oil inspection, the unit achieves ≥12,000 operating hours (approx. 8 years at 4 h/day usage), per accelerated life testing per IEC 60068-2-64.
Is remote monitoring supported natively?
Native Ethernet or Wi-Fi is not integrated; however, third-party IoT gateways with Modbus-to-MQTT translation enable cloud-based status tracking and predictive maintenance alerts.
