Thermal Cleaning

Properly used, thermal cleaning will remove contaminants while also avoiding any damage to the hardware and parts being cleaned, as well as its metallurgy. This makes the process safer for the environment, people, and even reduces the cost of cleaning.

Our clients know that they can trust Carolina Filters to utilize their knowledge and experience to expertly use these techniques to get a clean, finished product. The three main processes that we offer to clients are:

Convection Ovens with Steam Controls

We use this process to clean parts of polymers, plastics, degraded polymers, carbon, and charred materials. It can be used with large or small parts with varying amounts of contaminant. Parts that are commonly cleaned this way include:

  • Housings
  • Canisters
  • Process piping
  • Dies
  • Tubesheets
  • Screens
  • Extruder screws
  • Heat exchangers
  • Mixers

Contaminants that can be removed through either standard or controlled burnout procedures include:

  • Oils
  • Polymer and plastics
  • Organics
  • Carbon buildup

Vacuum Oven with Oxidation (VacuClean)

Fragile parts that could potentially be damaged, should spontaneous oxidation occur, are typically cleaned this way. This process will rid parts of contaminants like polymers, plastics, degraded polymers, extruder screws, and any other contaminant that requires controlled oxidation or burning. We frequently use this technique on parts such as:

  • Filters
  • Dies
  • Filter assemblies (such as stacks and candles)
  • Spinnerets
  • Similar fragile parts

Salt Bath Processes

This process is used for polishing items. In order to protect parts being cleaned in the salt bath process from damage, any polymers or plastics must be removed before putting them in the salt bath. This process helps to rid parts of rust, scale, additives, and any charred or degraded material. Salt bath cleaning works well for parts such as:

  • Filters
  • Dies
  • Extruder screws
  • Mixers
  • Heat exchangers
  • Spinnerets
  • Related parts

Our burnout and thermal cleaning services are cost-effective alternatives to in-house cleaning while producing cleaning results that are superior to what can be achieved with in-house equipment.

At Carolina Filters, we apply an understanding of chemistry and metallurgy to customize procedures that will remove unwanted substances without damaging your valuable parts. Our chemists and engineers use the latest technology to determine the most safe and effective burnout cleaning procedures. When necessary, we can employ ramp and heat soak cycles to work with delicate parts like heat exchangers. For projects that involve solvent chemistries, Solvent Cleaning is more appropriate.

For your peace of mind, we are happy to provide advanced information, including charts and graphs that show the temperature profiles for processes used to clean your parts. We use a number of different pieces of thermal cleaning equipment, which allow us to service a wide variety of part sizes and configurations, as well as handle large-capacity orders.
