Preparing Insulation Equipment and Materials for the Winter

by | Nov 20, 2024 | Tips and Tricks

As the cold weather approaches, here are a few things to remember to keep your equipment and materials ready and in good condition.

Water Pump:

  1. Expansion of Ice: Water expands as it turns to ice. If water inside the pump or its pipes freezes, it can create pressure on the pump’s housing, seals, and internal components.
  2. Cracked or Damaged Casing: The expansion of ice can crack or split the pump casing, potentially leading to leaks and rendering the pump unusable.
  3. Broken Internal Components: Internal parts such as seals or rings can be damaged if frozen water causes them to seize or crack.
  4. Blocked Flow: If water freezes within the pump or its connected pipes, it can block the flow entirely. Even once it thaws, residual ice or debris may continue to obstruct water movement.
  5. Motor Strain: If the pump is powered on while it is frozen, the motor may overheat or burn out due to the inability to circulate water properly.

Vacuum Bags

This vacuum bag was stored for over one year. The chemicals are disintegrating.

Vacuum bags are made from Non-woven Polypropylene (NWPP). It is a chemical used to create the disposable bags and is susceptible to various conditions.

  1. Keep Away from Direct Sunlight: NWPP can degrade if exposed to prolonged sunlight or UV rays. Store it in a shaded or indoor area to minimize degradation.
  2. Temperature Control: Avoid exposing the material to extreme temperatures. Ideally, it should be stored in a cool, dry environment, typically at temperatures between 15°C to 25°C (59°F to 77°F).
  3. Dry Storage Environment: Humidity can affect NWPP, potentially leading to mold growth or material deformation. Ensure that the storage area is dry and well-ventilated.
  4. Avoid Contact with Chemicals: Keep the fabric away from harsh chemicals, such as solvents, oils, or acids, which may degrade or alter its properties.
  5. Stacking and Weight Considerations: If storing NWPP in rolls or stacks, avoid over-stacking, which could cause crushing or deformation. Use pallets and racks to distribute weight evenly and ensure the material remains in its original shape.
  6. Longevity: Vacuum bags will degrade over time. The chemicals break down. “Polypropylene nonwoven fabrics naturally decompose if left outside and have a maximum life of just 90 days. If PP nonwoven fabric is kept indoors, it lasts for five years.” [source: StraitsResearch]

Grease Bearings on the Machines

  1. Lubrication in Cold Temperatures: Grease reduces friction between parts, preventing wear and tear. In cold weather, metal can contract, and without proper lubrication, mechanical parts are prone to sticking or seizing up.
  2. Protection Against Moisture: Winter often brings increased exposure to snow, ice, and water, which can lead to rust and corrosion. Grease acts as a barrier, protecting metal parts from moisture and preventing rust formation.
  3. Prevention of Freezing: Cool Machines uses red or blue grease for the bearings. This grease prevents moisture from getting between the gears, and keeps moving parts from freezing together to ensure smooth operation.

These are a few things to note before freezing temperatures hit. Cold weather has an impact on equipment and this blog post is designed to highlight places that are susceptible to freezing temperatures.
