Engine Library

At Firwin, we pride ourselves on our extensive engine insulation knowledge base. With over 30 years in the industry, we have amassed a comprehensive library of engine projects, with insulation specifications and requirements for every engine we have experienced.

Firwin’s engine library features templated insulation blanket designs, allowing for more efficient fabrication of products for these engines and facilitating an especially quick turnaround.

Why Engines Require Insulation

To ensure optimal engine operation and reduce heat in the surrounding area, engines and exhaust systems require appropriate insulation. Adequate insulation offers the following benefits:

• Heat containment. Insulation keeps the high heat generated by an engine confined around the engine and exhaust system. By maintaining the heat in the engine and exhasut system, equipment can function at optimal capacity, thereby reducing emissions.
• Personnel protection and safety. Engine insulation protects employees from exposure to the extreme heat on engine surfaces and within the working environment. The amount of heat generated by an engine can cause extreme harm to individuals, resulting in burns, heat exhaustion, and heat stroke. Insulation also reduces noise levels, thereby protecting the hearing of workers in the vicinity.
• Component shielding. In addition to protecting employees from heat, an insulated engine also protects components and sensitive equipment around the engine from heat damage.

Benefits of Firwin’s Engine Library

Firwin’s extensive engine library represents the culmination of three decades of hands-on experience in finding insulation solutions for a wide array of engine and exhaust systems and components. This familiarity with the unique components of each system has a number of benefits:

Quick Quote Turnaround Times

Given our broad range of experience with numerous engine models, we have created an extensive catalog of template designs for a wide variety of engines and components. What this means to our customers is that when they come to us with an engine that needs insulation, more often than not we already have an existing blanket kit. This means less legwork for our customers (they do not need to go to the site and take engine and exhaust measurements) and a quick quote turnaround, as all the insulation blanket pricing is already in our system.

In addition, we consistently update our insulation templates as we acquire new information, so just because a make and model does not appear on our site does not necessarily mean we do not have an existing pattern for it.

Properly Designed Blankets

Being familiar with the intricacies of an engine, and having already gone through the process of designing and fitting blankets for an engine, the resulting product is a blanket that will precisely fit your particular engine and exhaust.

Firwin Customization

If we do not have a template for your particular engine model or component, not to worry. As a full-service custom fabricator of insulation solutions, Firwin’s capabilities include designing and building custom insulation solutions for any engine and exhaust component variation. We have measuring templates that make the job of measuring easy, and we show you exactly what dimensions we require.

Examples of Engine Models in the Library

Our comprehensive engine library includes templates for insulation solutions developed over the past 30 years, catering to all manner of engine styles and components. Our library contains, but is not limited to, templates for the following:

• Caterpillar Engine Insulation
• Cummins Engine Insulation
• Dawoo Engine Insulation
• Daimler Chrysler Engine Insulation
• Detroit Diesel Engine Insulation
• Deutz Engine Insulation
• EMD Insulation
• Ford Engine Insulation
• GM Engine Insulation
• John Deere Engine Insulation

Clean Water and Removable Insulation Blankets – Sounds Good!

When one thinks of clean drinking water, many things may come to mind – natural water sources, reservoirs, treatment facilities, to name a few. But you may be surprised to learn that removable insulation blankets have a role to play in bringing that fresh water to your table.

Sometimes, that role has to do with heat management. But every so often, we are called upon to helped with sound and vibrations issues that can crop up in industrial facilities. And such was to case recently at a local water treatment plant, where the ‘Ozone Generators’ (used to disinfect the water at the treatment plant) were letting off some ‘not so good vibrations’, making the surrounding area uncomfortable to work in.
After a study recommended removable insulation as a solution to the excess noise and vibration, the Firwin team was called in to propose a solution.

The final product was a blend of 2″ thick mineral insulation coupled with a lb/ft² sound sheet. Since only ends of the vessel were to be covered, our design engineers also had to incorporate a unique fastening method to ensure that the blankets remained in place.

A follow up study done by the Generator manufacturer concluded that “by covering the Generator covered at both ends with a noise blanket, the noise was greatly reduced below the specification requirements of 80 dbm”.

If you need some help on a sound or vibration issue, feel free to give us a call.
