NW308 Solid Dice cube – 140Kgs/24Hrs

Scotsman NW308 Ice Machine Detailed Summary (South Africa)

Key Specifications

• Ice Production: Up to 146–160 kg (321–352 lbs) of ice per 24 hours, equivalent to approximately 9,733–10,666 full dice cubes (15g each), calculated at 10°C ambient and 10°C water temperature. Production varies slightly by source (e.g., 140 kg/24 hours per H2O International SA).
• Storage Capacity: Head-only ice maker; requires a separate storage bin (e.g., SB193 with 129 kg capacity or B150 with 150 kg capacity).
• Cube Type: Dice ice cubes, clear and solid, with a bottom rim of 3–4 mm and a small depression of 9–10 mm. Full dice (15g) standard, with half dice (7g) or large dice available on request.
• Dimensions (Head Only):
  • Width: 560 mm (22 inches)
  • Depth: 620 mm
  • Height: 575–662 mm
• Weight: Approximately 65–70 kg (head only).
• Power Requirements: 230 V, 50 Hz, single phase, ~650–700 W, 10 A fuse, with power consumption of ~15–17 kWh/24 hours.
• Refrigerant: R-404A or R-290 (propane) in EcoX models, with a low global warming potential (GWP) of 3, compliant with F-Gas regulations.
• Condensing System: Available in air-cooled, water-cooled, or air-cooled remote versions. Air-cooled models feature top exhaust airflow, requiring no side clearance (22” 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: Requires connection to a 20 mm diameter sump drain at the back of the unit. No built-in Progressive Water Discharge (PWD) system, unlike EC-series models.

Key Features

1. Dice Ice Cubes:
   • Produces clear, solid dice ice cubes with maximum liquid displacement, ideal for general-purpose drink cooling and blended drinks due to their “softer” texture, which reduces strain on blender bearings. Suitable for quick-service restaurants (QSR) and coffee chains.
   • Vertical evaporator technology ensures large ice production at lower operating costs.
   • Available in full dice (15g), half dice (7g), or large dice sizes to suit various applications.
2. Design and Build:
   • T304 Stainless Steel Panels: Durable, resistant to wet conditions, and hygienic, ensuring longevity and a professional appearance.
   • Compact Footprint: Global standard 22-inch footprint follows international imperial standards, with top exhaust airflow requiring no side clearance, ideal for space-constrained environments.
   • Head-Only Design: Requires a separate storage bin (e.g., SB193, B150, B220, or B320), allowing customizable storage solutions for different business needs.
3. Maintenance and Hygiene:
   • One-Touch Cleaning: Initiated by pressing the clean button for 2–3 seconds, reducing labor costs and simplifying the cleaning process. Uses 180 ml of Scotsman Ice Machine Cleaner for the NW308, followed by automatic rinsing after 10 minutes.
   • Front-Access Evaporator: Immediate access to the evaporating plate for quick self-maintenance.
   • Condenser Air Filter: Removable and washable for easy maintenance, recommended monthly cleaning.
   • XSafe Sanitation System: Integrated 24/7 natural sanitation to keep the machine clean and safe, offering protection against bacteria and viruses, including COVID-19.
   • 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.
4. Ease of Use:
   • Electronic Controls with Auto-Alert Indicator Lights: Front console panel includes reset/washing, alarm (high pressure or general), bin full, operation, and power supply LEDs for user-friendly operation and diagnostics.
   • Ice Thickness Sensor: Adjustable to maintain a 3–5 mm clearance between the sensor and evaporator cells, ensuring consistent cube size.
   • Automatic Operation: Water pump, inlet valve, purge valve, and harvest valve work in sync to optimize production and conserve resources.
5. Top Exhaust Airflow:
   • Air-cooled models exhaust hot air from the top, eliminating the need for side clearance, enhancing installation flexibility in tight spaces.

Applications

• Ideal for restaurants, bars, hotels, supermarkets, liquor stores, and ice-selling businesses where high volumes of ice are needed for cooling drinks or blended beverages.
• Dice ice’s “softer” texture and rapid production make it perfect for QSR, coffee chains, and blended smoothies or cocktails.
• 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.
• Installation Requirements: Requires a permanent water supply (3/4” inlet) and drainage (20 mm sump drain). Must be connected to a neutral wire and solid earth ground to prevent electrical shock or equipment damage. Not designed for stacking, unlike larger NW models (e.g., NW458, NW608).
• Storage Bin: Must be paired with a separate bin (e.g., SB193: 129 kg, B150: 150 kg, B220, or B320). Bin selection depends on business needs.
• EcoX Initiative: Some NW308 models use R-290 refrigerant, making them environmentally friendly and compliant with F-Gas regulations.

Reliability and Warranty

• Warranty: Includes a 12-month warranty on parts and workmanship from the date of installation
