Overview
The DELEITE IMS-150 Fully Automatic Flake Ice Machine is an engineered solution for laboratories, clinical facilities, pharmaceutical QC labs, and research institutions requiring consistent, hygienic, and rapidly cooling ice in granular flake form. Unlike cubed or tube ice, flake ice is produced via a direct-contact freezing process on a vertically oriented, refrigerated drum surface—followed by mechanical scraping using a precision-ground spiral auger assembly. This dual-spiral extrusion method ensures continuous separation of ice from meltwater without residual pooling, eliminating the need for manual defrost cycles or water waste. The IMS-150 operates on a hydrocarbon refrigerant (R290), fully compliant with global environmental directives including the Kigali Amendment and EU F-Gas Regulation, while its sealed R134a-compatible compressor delivers stable thermal performance across ambient temperatures up to 43°C. Designed to meet ISO 13485-aligned manufacturing protocols and CE-marked per EN 60335-1 (Household and Similar Electrical Appliances – Safety), the unit integrates passive thermal insulation (CFC-free polyurethane) and an antimicrobial interior liner certified to ISO 22196 for bacterial reduction (>99% against S. aureus and E. coli).
Key Features
- Stainless steel 304 enclosure with electropolished finish — corrosion-resistant and compatible with laboratory-grade cleaning agents (e.g., 70% IPA, sodium hypochlorite solutions)
- Dual-mode cooling system — selectable air-cooled or water-cooled condensation, enabling flexible installation in confined or heat-sensitive lab environments
- Microprocessor-based control board with industrial-grade imported ICs — supports real-time monitoring of evaporator temperature, compressor duty cycle, and ice thickness feedback
- Self-regulating float valve water inlet system — prevents overfilling, eliminates standing water, and ensures zero residual moisture after shutdown
- Acoustically optimized right-angle hollow-shaft gearmotor — operates at ≤58 dB(A) under full load, suitable for proximity to analytical instrumentation
- Integrated safety architecture — includes automatic shutdown on ice-full detection, low-water cutoff, evaporator overcooling protection, and thermal fuse backup
- Auto-restart with memory retention — resumes pre-interruption operational state following power or water supply restoration
Sample Compatibility & Compliance
The IMS-150 produces irregular flake ice with median particle dimensions of 1.2–1.8 mm and specific surface area exceeding 2,400 cm²/g — ideal for rapid thermal equilibration of biological samples (e.g., tissue homogenates, enzyme assays, PCR prep), cryopreservation workflows, and cold-chain validation studies. Its ice output meets ASTM D4169-23 requirements for refrigerant stability in distribution testing and complies with USP guidelines for laboratory equipment qualification. All electrical components carry TÜV/VDE certification (IEC 60335-1, IEC 61000-6-3), and material declarations conform to RoHS Directive 2011/65/EU Annex II. The unit is designed for GxP environments: audit trails are supported via optional RS485 Modbus RTU interface (compatible with LabVantage, STARLIMS, and Limis platforms), and firmware logs retain timestamps for all critical events per FDA 21 CFR Part 11 data integrity principles.
Software & Data Management
While the IMS-150 operates as a standalone appliance, its embedded controller provides serial communication capability (RS485, Modbus RTU protocol) for integration into centralized facility monitoring systems. Optional firmware upgrade enables periodic export of operational logs (compressor runtime, ice production intervals, fault codes) in CSV format. All status indicators — including “ICE FULL”, “LOW WATER”, and “EVAPORATOR OVERCOOL” — are mapped to discrete digital outputs for PLC interfacing. No proprietary software is required; configuration and diagnostics are accessible via front-panel LED indicators and tactile membrane buttons. Firmware versioning follows IEC 62304 Class B medical device software lifecycle standards, with documented change control and regression testing records available upon request.
Applications

- Pharmaceutical QA/QC: Cold storage of reference standards during HPLC sample preparation
- Food safety testing: Rapid cooling of microbiological enrichment broths prior to plating
- Chemistry departments: Temperature control in exothermic reaction quenching and distillation condensate collection
- Biobanking: Supplemental cold mass for LN₂ dewar top-off during vial retrieval operations
FAQ
What refrigerant does the IMS-150 use, and why is it environmentally compliant?
The IMS-150 uses R290 (propane), a natural hydrocarbon refrigerant with zero ozone depletion potential (ODP = 0) and global warming potential (GWP = 3). It complies with EU Regulation (EU) No 517/2014 and EPA SNAP Program Acceptance Criteria for laboratory ice machines.
Can the IMS-150 be installed in a temperature-controlled server room or cleanroom?
Yes — when configured in water-cooled mode with closed-loop chiller integration, the unit achieves ≤32 dB(A) acoustic emission at 1 m distance and generates no localized heat load beyond nominal ventilation requirements.
Is the ice output suitable for ISO/IEC 17025-accredited testing laboratories?
Yes — the flake morphology, consistent density (0.38–0.42 g/cm³), and absence of chlorine residuals (verified per ASTM D1293) support traceable thermal performance in method validation protocols.
Does the unit support GLP-compliant operation?
It provides timestamped event logging (via optional RS485), physical lockout of parameter changes, and user-accessible calibration verification points — fulfilling core GLP Annex 11 expectations for ancillary lab equipment.
What maintenance intervals are recommended for uninterrupted service?
Daily visual inspection of water filter and drain pan; quarterly descaling of evaporator drum using citric acid solution (0.5% w/v); annual compressor oil analysis and refrigerant charge verification per ASHRAE Guideline 3-2023.
