Cold Challenges: Addressing Unique Factors of CDLR or Chain Conveyor Installations in Freezer Environments

industrial freezer

When applying chain or chain-driven live roller (CDLR) conveyors in a cooler or freezer application, there are several considerations to keep in mind due to the unique environmental conditions. Here are some important factors to consider:

  1. Temperature Range:
    Coolers and freezers have low temperatures that can significantly affect the performance and lifespan of conveyor components. Ensure that the selected chain and CDLR components can withstand the specified temperature range without compromising their structural integrity. Verify the temperature limits specified by the manufacturer to ensure compatibility.

  2. Lubrication:
    Low temperatures in coolers and freezers can impact lubrication effectiveness. Consider using low-temperature lubricants specifically designed for cold environments. These lubricants have a lower viscosity and maintain their lubricating properties in colder temperatures, ensuring smooth chain operation and minimizing wear. This can apply to conveyor roller bearings, chain lubrication, mounted bearings, and gear reducer lubricant.

  3. Material Selection:
    Choose materials for the chain, sprockets, rollers, and other conveyor components that can withstand the low temperatures without becoming brittle or losing strength. Many chains significantly degrade in low temperature applications.

  4. Moisture and Condensation:
    Moisture is common in cooler and freezer environments due to temperature differentials. Consider the potential for condensation and water exposure. Select components with corrosion-resistant coatings or materials that can withstand moisture to prevent rust and degradation. Proper sealing and drainage systems should be in place to minimize the accumulation of moisture if present.

  5. Motor Selection:
    Select motors and reducers that are rated for low-temperature operation. Ensure that they have the necessary insulation and if required heating features to prevent freezing and maintain optimal performance.

  6. Pneumatic Devices:
    Pneumatic devices are not recommended in applications where temperatures go below 32 degrees Fahrenheit. Moisture in the compressed air system can freeze, increasing the likelihood of equipment downtime.

  7. Safety Considerations:
    Cold environments can pose additional safety hazards for personnel. Take measures to prevent slips and falls by using non-slip flooring and providing adequate lighting. Ensure that emergency stop buttons and safety guards are easily accessible and functional.

  8. Regular Maintenance:
    Implement a robust maintenance program to monitor and inspect the conveyor system regularly. This includes checking for wear, lubrication levels, and signs of damage. Regular maintenance helps identify potential issues before they lead to breakdowns or unsafe conditions.
