Providing dependable coil solutions for over 90 years.
Since 1925, our company has manufactured quality heat transfer, refrigeration, and air handling equipment for industrial, commercial, utility, and marine markets. Our custom engineered Marlo heat transfer solutions are used in a variety of configurations to cool, heat, and dehumidify air streams for process and building comfort.
At Marlo, all employees are committed to continuous quality improvement in all that they do. Our intent is to meet or exceed our customers' expectations for on-time delivery and robust product performance for all of our commercial HVAC Marlo Heat Transfer products.
Our heat transfer products are manufactured from quality materials typically in heavier grades and thicknesses. This ensures dependable performance and years of service, even in the most demanding conditions.
Our commercial coil Quality Management System has expanded from a process into an ISO 9001 certified system. Our registrar (NQA of Acton, Mass.) conducts semi-annual surveillance audits. Additionally, Leonardo DRS can offer Marlo Heat Transfer products that comply with Section VIII of the ASME Boiler and Pressure Code. We hold a “U” Stamp for the design and fabrication of Unfired Pressure Vessels. This system is monitored by both an authorized inspection agency in accordance with the National Board as well as a NUPIC utility.
