MarloAIR™ Air Handling Unit

The modular air handling unit that configures to meet your specific needs

With the MarloAIR™ you no longer have to choose between high-priced custom AHUs with long lead times, and off-the-shelf units with limited features that don’t meet all your needs. Now you can get the best of both worlds: a pre-engineered unit (which reduces both cost and delivery time) with a variety of modules that can be configured for your specific application, from 8,000 to 24,000 CFM.

Designed, Engineered and Built by the Heat Transfer Experts
At Marlo, we have more than 90 years of experience providing custom heat transfer solutions. Marlo coils are trusted throughout the industry for quality, performance and reliability – and for meeting our customers’ broad range of diverse needs. In addition, the Marlo Stratomizer® Dampered Face & Bypass Coil is well-known for its ability to efficiently preheat and temper outside air, and to protect against freezing.

Backed by a 3-Year Warranty
With our proven coils and optional Stratomizer at the heart of every MarloAir AHU – plus top-quality materials throughout the unit – you can count on years of dependable service. That’s why we have the confidence to back the MarloAIR with a full 3-year warranty – three times the industry standard.

Built-In Advantages

No Matter How It's Configured, The MarloAIR™ Has a Range of Built-in Advantages

Superior Wall SystemWall System
We designed and built the MarloAIR wall system to provide excellent insulation value with minimal air leakage, including 2" foamed panels, integral thermal breaks and full-perimeter, double-sealed gaskets. Plus, every panel is constructed of galvanized steel for superior strength and durability, and is coated with PVC to resist bacteria and corrosion.

Modular Design
The pre-engineered MarloAIR can be customized to meet your specific needs without the high costs and long lead times of typical custom units. The modular design allows for easy transport to and through your building. Assembly is fast and easy. And its small footprint saves valuable floor space.

Proven Marlo Performance
The MarloAIR is built around Marlo’s industry-leading coils and Stratomizer, giving you the reliable performance that comes with our 90-year track record of innovation, quality production and thermal management expertise. Our coils undergo extensive in-house testing and are AHRI certified.

Energy Efficient Design
Air leakage and thermal transfer are the largest contributors to AHU inefficiency and increased operating costs. That’s why we added a number of extra features to maximize efficiency, including our airtight (SMACNA leak class 9 for positive pressure and class 1 for negative pressure) fully insulated wall and floor panel system, double-walled and gasketed access doors, and state-of-the-art, direct-drive, energy efficient fan and motor assemblies.

Components

MarloAIR™: Quality Built Into Every Component

MarloAIR Quality Built Into Every Component

Marlo’s industry-leading chilled water, hot water or steam coils provide both excellent performance and long life. Various circuit options are available with full-size return bends and properly sized headers to ensure uniform flow and minimized pressure loss.

A Marlo exclusive, the Stratomizer Dampered Face & Bypass Coil offers a proven and efficient method of preheating and tempering fresh outside air by enabling the use of full steam pressure or hot water flow to the coil at all times – eliminating freezing.

The MarloAIR’s frame is made of military grade extruded aluminum to provide years of rust-free performance, and features an integral thermal break to minimize thermal transfer.

All wall panels are constructed of galvanized steel and are insulated with a 2" polyurethane foam core, offering energy efficiency and the prevention of condensation build up on exterior surfaces. The insulation is UL 94 V-O fire rated.

Access doors feature double wall construction with a minimum of two tapered pawl latches to uniformly compress the door gasket (made of closed cell neoprene) into the door jamb for an air-tight seal.

The base is constructed of 10-gauge galvanized steel with reinforced ribs for extra support.

The MarloAIR’s floors are constructed of heavy-gauge aluminum diamond plate to protect the insulated floor panels from damage. Floor panels are made from a sandwich of 24-gauge steel sheets on the outside with high-efficiency polyurethane foam insulation in the center. A durable coating is applied to the steel panels at the factory for added protection.

The integral insulated stainless steel drain pan is double pitched, and conforms to ASHRAE standards for acceptable indoor air quality.

Energy efficient, direct drive fan and motor assemblies are designed to meet CFM and pressure drop requirements with minimal energy usage. All assemblies are mounted on vibration isolators.

Light kits can be added to any module to make inspection and maintenance easier.

Filter framing options include 2" pleated panel, 4" pleated panel and 12" rigid cartridge with 2" pleated panel.

Each extruded aluminum frame features an integral thermal break that resists heat transfer. Plus, all wall panels are constructed with a 2" polyurethane foam core for superior insulation value.

Stratomizer Dampered Face & Bypass Coil

The industry’s most reliable method of freeze protection. Proportioned quantities of air either bypass or are directed through the heating surface to achieve the required discharge temperature.
