Impact of Cold Weather on Dust Collectors (And Why You Should Winterize Your Facility’s System)

As winter approaches, preventive dust collection maintenance of your facility’s system helps ensure it operates effectively and efficiently in cold weather conditions. Though seasonal dust collector maintenance is advised for all systems, preparing for winter is particularly important. 

In cold weather, when windows and bay doors are shut to preserve heat, ventilation in facilities is, obviously, reduced. In other words, when those doors and windows are open in the warmer months, your system benefits from the natural airflow. When your building is sealed up for winter, your dust collection system has to work harder to filter the dust, particulates, gases, and contaminants from the work environment. At issue then, is how cold weather impacts your dust collection system.

The Impact of Cold Weather on Industrial Dust Collection Systems

Cold weather can adversely affect your dust collection system’s performance and lead to higher energy costs. The effects of cold weather can vary depending on the specific design and the severity of the cold conditions. At the very least, if your dust collection system needs to work harder to maintain desired operating conditions, it can lead to increased energy consumption and operating costs.

One of the primary culprits to consider is the effects of moisture and condensation buildup within a system during cold weather. Moisture in the air can cause dust particles to freeze within the system. When moisture condenses into water droplets on cold surfaces, it can freeze on contact. In the air or on surfaces, moisture and condensation buildup can obstruct airflow, damage components, and lead to reduced efficiency of the system. Condensation can also lead to issues like rust, corrosion, and clogging of filters and ducts, as well as promoting the growth of mold or bacteria in the system.

Freezing conditions can cause operational problems for any system. Extremely cold temperatures can prevent the system from operating efficiently. Frozen filters, ducts, or hoppers can result in reduced airflow and pressure, potentially leading to equipment damage and operational issues. This is of particular importance for systems that are situated outside of buildings. The temperature differential can cause problems with the compressed air pulsing system and issues with the electronics in control systems. Now is the time to add heat tracing to the compressed air lines if freezing is routinely an issue in cold weather.

Cold conditions can change the properties of the materials being collected as well. For example, harmful particles that become more brittle can create dust that is more difficult to capture and control. This becomes more of a challenge if the colder conditions are affecting proper airflow through the system, interfering with the pressure required to efficiently draw in dust and maintain a consistent flow rate. Inadequate collection ultimately results in decreased air quality in the industrial facility.

As cold weather can affect the performance of various components of a dust collection system, like fans and motors, lubricants and seals may also be less effective. This can lead to increased wear and tear on the equipment, and a risk of equipment failure or damage.

Why You Should Winterize Your Facility’s Dust Collection System

The direct answer to that statement is to maintain air quality within the facility throughout the winter months, as well as to efficiently manage energy costs, you should winterize your facility’s system to ensure it operates efficiently. 

Some specific steps for winter preventive dust collection maintenance starts with checking the differential pressure gauge readings along with a visual inspection of filters for damage, clogs, tears, holes or wear. Readings higher than 6 inches of water gauge is an indication filters approaching the end of their life. Otherwise, upon inspection, replace any damaged or worn-out filters to maintain effective filtration.

Inspect all seals, gaskets, and connections for wear, damage, or leaks, and replace any worn parts. In extremely cold climates, consider insulating ductwork, particularly near the dust collector, to prevent condensation and freezing. Insulation can help maintain consistent temperatures inside the system. If necessary, install heating elements where needed in the hopper and housing. This will prevent build-up of condensation inside the dust collector. 

Compressed air lines of pulse valve cleaning systems in dust collectors located outside should be cleared of any moisture and condensation to prevent freezing of air lines that can restrict airflow and clog filters. A solenoid heater kit fitted to your dust collector can remedy the problem.

In advance of the cold weather, fans should be balanced and properly aligned, and motors should be lubricated as needed. During winter weather, keep air inlets and exhaust vents clear of snow, ice, or debris to maintain proper airflow. Using weather-resistant covers or hoods to protect these openings can help throughout the year.
