Cube Type: Gourmet supercubes, individual, transparent, crystal-clear, thimble-shaped, weighing 20g (medium cube standard, 30 mm diameter x 34 mm H), with small (8g, 21 mm diameter x 25 mm H), large (39g, 38 mm diameter x 41 mm H), or extra-large (60g, 44 mm diameter x 46 mm H) cubes available on request.
Dimensions (Head Only):
- Width: 773 mm
- Depth: 704–705 mm
- Height: 721 mm
Weight: Approximately 85 kg (head only, shipping weight up to 88–95 kg).
Power Requirements: 230 V, 50 Hz, single phase, 1850 W, 16–20 A, with power consumption of ~28–30 kWh/24 hours.
Refrigerant: R-404A or R-290 (propane) in EcoX models (e.g., MXG M 437 AS OX), with a low global warming potential (GWP) of 3, compliant with F-Gas regulations.
Condensing System: Available in air-cooled (A), water-cooled (W), or air-cooled remote versions. Air-cooled models feature top exhaust airflow, requiring no side clearance (30-inch footprint).
Water Requirements:
- Minimum water temperature: 5°C
- Maximum water temperature: 38°C
- Minimum water pressure: 1 bar (14 psi)
- Maximum water pressure: 5 bar (70 psi)
Drainage: Equipped with a Progressive Water Discharge (PWD) system, which pumps excess water up to 15 meters away and 1.7 meters high, addressing drainage challenges. Includes a non-return valve to prevent drain water back-flush, enhancing hygiene.

Key Features

Gourmet Supercubes:
- Produces crystal-clear, slow-melting, thimble-shaped supercubes that enhance drink presentation and maintain chill longer, ideal for premium venues like fine-dining restaurants, bars, and luxury hotels. Cubes are individually formed by spraying water upward into an inverted mold, ensuring impurities fall away for pure, hard ice.
- Available in small (8g), medium (20g, standard), large (39g), or extra-large (60g) sizes to suit various applications.
Design and Build:
- T304 Stainless Steel Panels: Durable, resistant to corrosion, and hygienic, ensuring longevity and a professional appearance suitable for demanding commercial environments.
- Compact Footprint: Global standard 30-inch (773 mm) footprint follows international imperial standards, with top exhaust airflow requiring no side clearance (minimum 15 cm at sides and back for ventilation and utility connections).
- Head-Only Design: Requires a separate storage bin (e.g., B220, SB193, SB393, NB 530, NB 948), allowing customizable storage solutions.
Maintenance and Hygiene:
- One-Touch Cleaning: Initiated by pressing the clean button for 2–3 seconds, using 300 ml of Scotsman Ice Machine Cleaner in 3 liters of lukewarm water (max 40°C), followed by automatic rinsing after ~10 minutes, reducing labor costs.
- Front-Access Condenser Air Filter: Removable and washable, recommended for monthly cleaning to maintain performance and extend machine life.
- Scale Accumulation Prevention: Traps limescale in one place, minimizing maintenance issues and ensuring clean ice.
- XSafe Sanitation System: Integrated 24/7 natural sanitation using UV light to destroy 99% of bacteria and viruses, including COVID-19, preventing mold, mildew, slime, and odors.
- AgION Technology: Resists microbe growth and odor development for product protection.
- Clean Alert: External indicator lights blink to advise when cleaning is needed.
- Regular Bin Sanitization: The bin interior, in contact with food-grade ice, should be cleaned and sanitized weekly with a commercial food-grade sanitizer to prevent bacterial accumulation.
Ease of Use:
- Electronic Controls with Auto-Alert Indicator Lights: Front console panel includes LEDs for reset/washing, alarm (high pressure or general), bin full, operation, and power supply, ensuring user-friendly operation and diagnostics.
- Ice Thickness Sensor: Adjustable via DIP switches 1–4 to maintain consistent cube size, addressing issues like deep depressions in cubes due to short freeze cycles.
- Automatic Operation: Water pump, inlet valve, purge valve, and harvest valve work in sync to optimize production and conserve resources.
- Ergonomic Access: Sliding door on storage bin with a one-touch lift for easy ice access, enhancing bar staff efficiency.
Progressive Water Discharge (PWD):
- Built-in drain pump allows flexible placement by pumping excess water up to 15 meters away, solving drainage height and distance issues.

Applications

Ideal for coffee shops, cafes, restaurants, bars, hotels, nightclubs, and catering businesses where high-quality ice enhances drink presentation and customer experience.
Gourmet supercubes are perfect for premium, mixed, or carbonated drinks, creating a premium cooling effect and appealing condensation on bottles and cans.
Suitable for high-demand settings due to its high output and compatibility with large-capacity storage bins.

Operational Considerations

Environmental Conditions: Operates effectively in ambient temperatures from 10°C to 43°C and water temperatures from 5°C to 38°C. If ambient temperature is below 8°C, a water-cooled unit may be required; consult a sales representative.
Installation Requirements: Requires a permanent water supply (3/4” inlet) and drainage. The PWD system enhances placement flexibility. Must be connected to a neutral wire and solid earth ground to prevent electrical shock or equipment damage. Suitable for stacking with another MXG438 for doubled output (requires Scotsman stacking kit).
Storage Bin: Must be paired with a separate bin (e.g., B220: 190–220 kg, SB193: 100–129 kg, SB393: 181 kg, NB 530/FOL600: 243–258 kg, NB 948: 406 kg). B220 or NB 530 recommended for balanced capacity.
EcoX Initiative: Some MXG438 models (e.g., MXG M 437 AS OX) use R-290 refrigerant, making them environmentally friendly and compliant with F-Gas regulations.
Recommended Water Filter: HF60-S water filter recommended to maintain ice quality and machine performance, reducing scale buildup and extending machine life.
