Tube ice machines are renowned for their efficiency, high daily output (1–80 tons), and durability in industries ranging from hospitality to aquaculture. However, even the most reliable equipment can occasionally face operational hiccups. In this guide, we’ll walk you through common issues and solutions to keep your tube ice machine running smoothly—while highlighting why Pecold’s technology stands out.

Low Ice Production: Diagnosing the Root Causes
Symptoms: Reduced ice output, longer freezing cycles.
Possible Causes & Fixes:
- Insufficient Water Supply: Ensure water levels meet the machine’s Check filters and valves for blockages.
- Temperature Fluctuations: Tube ice machines operate optimally under standard conditions (ambient temperature 28°C, water temperature 23°C). Extreme heat or cold can affect performance.
- Refrigerant Issues: Low refrigerant levels (e.g., R404A/R22) may reduce cooling Consult a technician to inspect for leaks or recharge the system.
Pecold Advantage: Our machines are designed with energy-saving features to stabilize performance even under variable conditions.
Poor Ice Quality: Addressing Cloudy or Fragile Ice
Symptoms: Ice appears cloudy, melts quickly, or breaks easily.
Possible Causes & Fixes:
- Water Quality: Impurities in water cause cloudiness. Install a water softener or filtration system.
- Incorrect Ice Size Settings: Pecold machines offer customizable tube ice sizes (φ22mm/φ29mm/φ35mm). Adjust the settings to match your industry’s needs (e.g., thicker ice for seafood preservation)
- Evaporator Issues: Ensure the evaporator temperature remains at -15°C for optimal ice formation.
Machine Fails to Start: Electrical & Mechanical Checks
Symptoms: No power, unusual noises, or tripped circuits.
Possible Causes & Fixes:
- Power Supply Mismatch: Verify the machine’s power requirements (3P/380V/50Hz or customized voltage). Use a voltage stabilizer if fluctuations are common.
- Component Wear: Inspect motors and compressors for wear. Pecold’s durable construction minimizes long-term wear, but regular maintenance is key.
Frequent Maintenance Tips to Prevent Breakdowns
- Clean Condenser Coils: Dust buildup on condenser coils (designed for 40°C condensing temperature) reduces efficiency. Clean monthly.
- Lubricate Moving Parts: Apply food-grade lubricants to hinges and motors.
- Monitor Refrigerant Pressure: Schedule annual professional inspections to ensure refrigerant levels are optimal.
