Custom Engineering

Every building project is unique. In many cases, so are the heating and ventilation requirements. For projects that require something other than off-the-shelf solutions, contact Marley Engineered Products.

What You Need - The Way You Need It

Whether you need custom ventilation engineering or help developing a custom heating system, we can work with you to meet the specifications and unique needs of your project.

Our knowledgeable technical support staff, consisting of engineers, technicians, quality and safety specialists, is available to assist you with all aspects of customizing heating and ventilation solutions to fit specific spaces in a variety of building types.

The Choice is Yours

In addition, many of our products are available in a variety of standard colors or can be matched if you provide us with a color sample.

Certain custom products, such as our convectors and baseboards, can also be painted with a durable polyester powder coat finish or anodized for further corrosion resistance.

Should you design your own custom enclosure, Marley Engineered Products can provide the appropriate heating unit to fit. Custom enclosures can also be tested to UL or ETL specifications in our own laboratory.

If you are interested in learning more about how Marley Engineered Products can deliver a custom solution, contact us.
