The Complete Refrigerant Selection Guide for 5-Ton Tube Ice Machines

Choosing the optimal refrigerant for your 5-ton tube ice machine impacts operational efficiency, environmental compliance, and total ownership costs. As global regulations tighten and refrigerant technologies advance, industrial users must make informed decisions about their tube ice making machine systems.

Industrial Refrigerants: Technical Analysis for Tube Ice Production

R22 (Traditional HCFC)

• Characteristics: Historically dominated industrial refrigeration due to excellent thermodynamic properties (-20°C evaporation temperature suits ice production).
• Limitations: Phased out globally under the Montreal Protocol due to ozone depletion potential (ODP=0.05). New installations are prohibited in most countries.

R404A/R507 (HFC Blends - Current Standard)

• Adoption: Primary refrigerants in modern tube ice plant equipment like the BAOCHARM 5-ton systems, offering -20°C evaporation temperatures ideal for rapid ice formation.
• Environmental Impact: Zero ODP but high Global Warming Potential (GWP=3,922). Subject to Kigali Amendment phase-down schedules.

R134a (Mainstream HFC)

• Applications: Common in smaller ice machines; operates efficiently at higher temperatures (-10°C to -15°C).
• Constraints: Lower volumetric cooling capacity makes it less energy-efficient than R404A for 20 tons tube ice machine installations.

R717 (Ammonia - Natural Refrigerant)

• Performance: Delivers superior efficiency (30%+ better heat transfer) in large tube ice factory setups.
• Safety Requirements: Toxic and flammable—requires specialized leak detectors/ventilation. Ideal for segregated industrial plants.

How to Select the Right Refrigerant: 4 Critical Factors

Regulatory Compliance

Verify local policies: R22 is banned for new installations; R404A faces EU F-gas restrictions. Emerging alternatives include R454C (GWP=148) and R290 (propane).

Efficiency & Operating Costs

R404A systems consume ~18kW power for 5-ton output; ammonia cuts energy use by 15–25% but demands higher maintenance. Low-glide refrigerants (e.g., R507) stabilize evaporation temperatures for consistent ice quality.

System Compatibility & Safety

Existing R22 systems can retrofit to R407F but require compressor adjustments. Flammable refrigerants (R290) need IEC 60335-2-89 compliance.

Environmental Conditions

High-ambient areas (≥40°C) require robust condensers—R404A handles heat better than R134a.

Practical Applications: Optimizing Your 5-Ton Tube Ice Machine

Food-Grade Ice Production

Use R404A/R507 with SUS304 stainless steel evaporators for direct-contact ice (e.g., beverages/food preservation).

High-Volume Industrial Sites

For 20 tons tube ice machine setups, ammonia or cascade systems provide scalable cooling with lower GWP.

Harsh Environments

Select compressors (Bitzer, Hanbell) and condensers rated for 100% operation at 40°C ambient temperatures.

Advanced Engineering Defining BAOCHARM’s 5-Ton Tube Ice Machines

1. Smart Refrigerant Integration: Our tube ice makers support R404A/R507A and future-proof R454C configurations, minimizing retrofit costs.
2. Energy Adaptive Components: Patented evaporators reduce freezing cycles by 25%, reducing usage costs.
3. Zero Contamination Guaranteed: Full SUS304/316L flow path PLC automation eliminates the risk of bacteria – HACCP/ISO 22000 certified.

Recommendations

For new tube ice plant installations, R404A/R507 offers the optimal balance of efficiency and cost. Retrofit projects should evaluate R454C. Food/pharma applications demand stainless steel evaporators + automated cleaning cycles.
