Commercial Three-Level Ladder Type Display Freezer

CECLE Three-level ladder type freezer stainless steel material with glass sliding door type upper refrigeration and lower freezing

I. Product Overview

1. Basic Equipment Information

  • Product Name: Commercial Three-Level Ladder Type Stainless Steel Sliding Glass Door Refrigerator & Freezer (Upper Refrigeration & Lower Freezing) / Stepped Fresh Food Self-Service Display Counter
  • Available Models & Configurations:
  • Push-Pull Freezer: Equipped with smooth tempered sliding glass doors for dust protection, temperature retention, and effortless access.
  • Classic Freezer: Standard open/self-service build catering to diverse kitchen and buffet layouts.
  • Sizes & Dimensions:
  • 1.5M / 60": Ideal for small-to-medium restaurant self-service bars and prep stations.
  • 1.8M / 71": Standard commercial high-capacity size, the top choice for high-traffic venues.
  • 2.0M / 78": Extra-wide 3-tier display surface, tailored for large-scale buffets and central kitchens.
  • Equipment Type: Commercial countertop/horizontal 3-tier ladder unit / Dual-zone partition display counter (Upper Refrigeration + Lower Freezing)
  • Market Positioning: Engineered specifically for self-service BBQ, hot pot, skewered food shops, banquet catering, kitchen prep lines, and fresh food retail. Its stepped vertical layout provides full, unobstructed visibility across dozens of ingredients simultaneously, dramatically optimizing customer flow and boosting sales per square foot.

Engineering & Manufacturing Highlights:

  • Dual-Zone Independent Temperature Control (Upper Chill + Lower Freeze):
  • Upper Refrigeration Zone (2°C to 10°C): Ideal for fresh cut vegetables, mushrooms, fruit salads, dipping sauces, and ready-to-cook fresh items.
  • Lower Deep Freezing Zone (0°C to -15°C): Ideal for long-term holding of sliced beef/mutton rolls, seafood, frozen meatballs, and prepared frozen delicacies—eliminating the need to buy two separate appliances.
  • Wrap-Around Direct Cooling Moisture-Lock Technology: Uses precision-fitted thermal conduction evaporator tubing, relying on natural physical convection and air descent. Unlike harsh fan-forced cooling that dries out and darkens exposed meats, this direct cooling system seals in juices and preserves natural color, significantly reducing shrinkage and product loss.
  • Heavy-Duty Stainless Steel Body & Powder-Coated Interior: Countertop surfaces and outer panels are made of premium corrosion-resistant stainless steel, resistant to grease, scratches, and heavy daily wear. The interior utilizes hygienic, powder-coated storage panels that are smooth, antibacterial, stain-resistant, and effortless to sanitize.
  • Ultra-Low Energy Consumption & Wide Climate Class (ST Subtropical Design): Rated power is only 300W. Combined with high-density polyurethane foam insulation and airtight sealing gaskets, it effectively blocks ambient heat infiltration. Built to the ST (Subtropical) climate rating, it maintains powerful, consistent cooling even in hot and humid commercial kitchen environments.
  • Movable Caster Feet: Comes standard with heavy-duty ball-bearing caster feet (equipped with locking brakes), allowing one person to easily reposition the unit during deep cleaning or layout reconfigurations.

2. Core Functions & Operating Principles

  • 3-Tier Stepped Convective Air Circulation: Cold air sinks naturally across the descending tiers, creating a stable sub-zero reservoir in the bottom freezing section and a gentle protective air curtain in the upper chilled section to keep every shelf safely within its target temperature range.
  • Dual-Zone Digital Thermostat System: Compatible with 110V/220V commercial power. Features an external digital microcomputer control panel that continuously monitors and adjusts both zones independently to prevent cross-temperature interference.
  • Integrated High-Density Foam Insulation: The cabinet is injected with high-pressure polyurethane foaming in a single process. Its high closed-cell ratio breaks thermal bridges, prevents outer condensation, and maximizes energy efficiency.

3. Core Value: Why Choose This Equipment?

  • Tiered Presentation Drives Impulse Purchasing: The 3-tier stepped structure eliminates the blind spots of traditional flat chest freezers, showcasing ingredients in an appetizing, panoramic layout that boosts appetite and increases customer grab-and-go frequency.
  • High Space Efficiency (2 Units in 1): Merges a conventional prep counter with a separate chest freezer into a single footprint, freeing up valuable floor space in busy kitchens and dining halls.
  • Energy Efficiency & Moisture Retention: The 300W low-wattage design delivers ongoing utility savings, while superior moisture retention cuts down on food waste from meat discoloration.

II. Production Workflow & Standard Operating Procedures (SOP)

1. Site Preparation & Pre-Installation Requirements (Key Success Factors)

  • Ventilation Clearance: Maintain at least 4–6 inches (10–15 cm) of clearance around the compressor ventilation louvers and the rear panel. Never block the airflow vents with boxes or storage items.
  • Pre-Startup Resting Rule: Upon arrival via freight, DO NOT plug in or turn on the unit immediately! Keep the unit upright on a level surface for at least 24 hours. This allows compressor oil displaced during transit to settle completely, preventing oil blockages that can degrade cooling performance or damage the compressor.

2. Pre-Startup Inspection & Workstation Setup

  1. Position the ladder freezer along your planned service or prep line, away from open flames, cooking ranges, or direct sunlight. Engage the front caster brakes to lock it firmly in place.
  2. Confirm your incoming voltage matches the rated specification (110V or 220V) and connect only to a dedicated, properly grounded wall outlet.
  3. Slide open the tempered glass doors and inspect the 3-tier pans and guide rails to ensure tracks are free of debris and glide smoothly.

3. Standard Operating Guidelines

  1. Empty-Load Pre-Cooling: Close the sliding doors, turn on power, and run empty for 1 to 2 hours. Wait until the digital display confirms that the upper zone has reached 2°C–10°C and the lower zone has reached 0°C–-15°C before loading food.
  2. Organized Tier Loading:
  3. Top & Middle Tiers: Load with chilled items such as vegetables, mushrooms, pre-mixed sauces, cold appetizers, and high-turnover self-serve dishes.
  4. Bottom Tier & Deep Well: Store frozen meats, raw seafood, meatballs, and frozen dumpling products.
  5. Important: Do not stack products higher than the sliding door tracks, as this will compromise the air seal.
  6. No Hot Foods Allowed: Cooked, blanched, or freshly fried foods must cool to room temperature in a preparation area before being placed inside the unit.

IV. Frequently Asked Questions (FAQ)

  • Q: Is frost buildup along the inner walls normal for a direct-cooling unit? How should it be defrosted?
  • A: Yes, frost buildup is a completely normal physical occurrence in direct-cooling refrigeration. As doors are opened repeatedly during busy shifts, ambient humidity condenses and freezes against the cold interior walls. When the frost layer reaches approximately 5 mm (0.2 inches), simply turn off the power at the end of the day, allow the frost to melt naturally, drain through the bottom drainage outlet, and wipe dry with a soft cloth. Never scrape interior walls with sharp metal tools.
  • Q: Why choose an "Upper Refrigeration, Lower Freezing" stepped design?
  • A: Naturally, cold air sinks while warm air rises. This layout works in harmony with physics: the upper tier provides gentle, uniform chilling that keeps vegetables crisp without freeze damage, while the dense cold air pools in the lower section to keep frozen proteins solid. This delivers both energy savings and integrated one-stop ingredient management.
  • Q: Will the tempered glass doors fog up in high-humidity weather and obscure the display?
  • A: The doors use commercial-grade insulated tempered glass to minimize temperature transfer. Additionally, the door frames feature airflow-break thermal barrier channels that substantially reduce condensation. Under extreme humidity, a quick wipe with a clean microfiber cloth instantly restores full visibility.
