Engine Component Insulation

engine component insulation

Essential to a wide range of industrial applications, engines  also introduce an element of risk into a work environment due to the intense levels of heat they can generate. Engine component insulation is designed to contain the heat produced by engines, protecting employees and sensitive equipment while optimizing engine performance.

The Problem

Industrial engines generate heat which can:

  • Raise ambient temperatures within the working environment to uncomfortable levels
  • Cause injury or illness to employees, such as burns or heat exhaustion
  • Damage nearby sensitive equipment and components, such as cables

These risks are especially potent for newer engines and smaller working environments. Newer engines are designed to reduce carbon emissions by running at higher temperatures (typically meeting or exceeding 800°F or 425°C). In smaller, more confined environments (such as those found in the underground mining industry), employees are at a greater risk of receiving severe burns due to contact with exposed metal engine parts.

Engine Component Insulation Solutions

At Firwin, we manufacture a variety of insulation products suitable for protecting employees and equipment from excessive engine heat, including:

Removable Insulation Blankets

Our removable insulation blankets are engineered from three layers of material for highly effective heat insulation. The three layers typically consist of:

  • An inner layer of steel mesh
  • A middle layer of insulation medium
  • An outer layer of silicone-coated fiberglass

The design of the blanket—its thickness and insulation medium—can be altered for greater heat reduction. For particularly demanding applications, other customization options include the integration of sound or fluid barrier material.

MineWrap Removable Blankets

Our MineWrap line of insulation blankets was specifically designed by our research and development team to meet the specific needs of the underground mining industry.

The flagship MineWrap™ Mark II features a flame-resistant foil inner liner lined with a stainless steel mesh. This design seals the insulation from oil or hydraulic fluid, thus eliminating a potential fire hazard. For more demanding applications, the MineWrap™ Mark III blanket features a reinforced stainless steel foil exterior covered by a layer of stainless steel mesh with options for additional joint safety seals.

Being durable and virtually impenetrable to contaminants, MineWrap™ is the insulation blanket of choice for many mining operations and mining equipment manufacturers.

Permanent Hard Coat Composite Insulation

Permanent Composite Hard Coat Insulation
In addition to removable blankets, we also offer a high-performance permanent insulation coating. This option is ideal for components that do not require regular repair or maintenance.

We apply the composite coating in a thin layer that both insulates the target material and protects it from combustion in the event of an engine leak or malfunction. Our Hard Coat product offers other advantages, such as:

  • Suitability for use in confined environments
  • Non-flammability and non-combustibility
  • Suitability for high-temperature environments
  • Burn protection for personnel
  • Reduction of ambient temperatures
  • Greater durability than removable blankets

For this type of insulation solution, we apply the coating to your disassembled components in our facility, then ship them back to you on a mutually agreed-upon timeline.

Stainless Steel Foil Insulation

metal foil insulationAnother permanent insulation option is metal foil insulation (MFI), which we pre-install over exhaust components, such as tubing, piping, and elbows. This insulation solution consists of insulation material encapsulated by an outer foil layer that is permanently welded to the engine component.

Our MFI is:

  • Durable (it is capable of withstanding steam washing and chemical exposure)
  • Leak-free (it serves as a barrier to any fluids that may seep into the insulation)
  • Customizable (it can be designed to fit different component shapes and application requirements)

With these considerations in mind, our MFI solutions also offer a tighter fit and more aesthetically-pleasing finish than insulation blankets. Original equipment manufacturers (OEMs) interested in this insulation solution can ship components directly to our factory where we custom fit and install the MFI before returning the parts.

Stop the Deep Freeze with Firwin

Wintertime, especially north of the border, means one thing: cold weather. Every year at this time, many of our industrial customers want to know if Firwin offers an insulation product that can keep piping and components from freezing. If you’ve ever owned a house, you know that frozen pipes can lead to disaster; now, just imagine if you are in charge of millions of dollars of industrial equipment under the same conditions.

At Firwin, we recognized that many of our customers operating in colder climates needed to find a way to both retain and create heat to keep their equipment safe and effective.  After a number of tests and prototypes, our R&D department came up with the perfect solution, the ‘pizza blanket’. Modeled after the insulated satchels pizza delivery people use to keep your food warm during transit, our pizza blanket introduces heat through a series of electric coils in order to prevent equipment from freezing up in harsh conditions. Of course, our pizza blankets are more than just heating pads; they also have all the properties of standard removable insulation blankets, including the ability to retain and contain heat. The combination of heating elements and insulation blankets means that our customers who operate in the harshest cold-weather conditions can be sure their facilities will constantly run at peak performance. 

So, if you’re facing a long cold winter and you need to know that your equipment won’t freeze up, contact Firwin today and let us tell you more about our innovative and cost-saving pizza blankets.

What to do about a square peg in a round hole?

Odd shapes and sizes are always something that design engineers encounter when creating everything from pipe fittings to fasteners. With insulation blankets, varying geometries and protrusions from engine and exhaust components and process piping are regularly encountered in the design phase.  At this point, when the surface to be covered isn’t smooth, how does that blanket fit?

Here is where our custom blanket services fit in. When it comes to the design portion of the production phase, our design engineers evaluate the surface and piping, and can create a blanket to accommodate any protrusions or cut outs.

How do we go about this with our customers? There are a few different options of reviewing and obtaining this kind of information. First and foremost, if the insulation blanket is needed in an emergency situation, with no lead time to make a custom cover, we can send a blanket and the customers can make the cut outs themselves according to the placement of the brackets. If that is not the situation, then our design engineers look at the end application. If the jacket will be covering a silencer, then they will supply the customer with a support brackets drawing they can fill out. If it’s a different component—such as for the oil and gas industry—we will then ask for CAD drawings or specific dimensions from the customer. Despite the application, it’s always pertinent for our design engineers to have drawings of the equipment that will be blanketed.

The most important aspect of the blanket design is that, according to our article, our “design team ensures that any cut-outs or openings are designed in such a way as to allow sufficient room for the protruding item, while minimizing any heat loss due to the lack of insulation.”

Whether you’re worried about complex geometries or protruding components on your equipment, don’t fear—our design engineers can create an insulation blanket for every application.
