Custom Air Handlers

Ventrol custom air handlers are designed for your specific needs for new construction, renovation and retrofit, and repair projects. We offer a broad range of options with units up to 300,000+ cfm. Ventrol has multiple innovative solutions for maximizing energy efficiency, reducing annual operating costs, improving indoor air quality, and achieving low sound levels. We offer knock-down construction, thermal break technologies, energy recovery technologies, FANWALL TECHNOLOGY®, and many other high quality custom air handling systems in various shapes, sizes, and configurations.

Thermal break technology - Ventrol's thermal break options minimize or prevent any condensation and frosting on the warm side of the panel caused by thermal bridging. Foam, fiberglass, or a combination of these insulations, is used along with a no-through metal design option to maximize thermal resistance between the interior and exterior of the cabinet.

Knock-down construction - We recognize not every project has easy access- particularly renovation and retrofit applications of older air handlers that are reaching the end of their useful life. Our knock-down construction option can provide the most cost-effective solution by avoiding the time and expense of a major tear-out and reconstruction project. In addition, the performance of your new system can be re-aligned to match current capacity and airflow requirements-with advanced technologies such as FANWALL TECHNOLOGY-to reduce operating expenses over the life of your new air handler.

Energy recovery ventilation - Ventrol's custom air handlers with energy recovery technologies are comprised of two counter-flow air tunnels with a common air-to-air heat exchanger transferring heat only, or heat and moisture, between the airstreams. Air-to-air heat exchangers carry the AHRI 1060 seal for AHRI CertifiedT performance for either wheel, plate or heat pipe heat exchangers. Integrating energy recovery technologies into the air handler design helps to capture the energy in the airstream, that would otherwise be exhausted to the atmosphere, and uses it to either pre-heat or pre-cool the outdoor airstream depending on the season. This pre-heating or pre-cooling can lead to significant energy savings and a reduction in the building's central plant size.

FANWALL TECHNOLOGY - Reengineering how you move air: compact, energy efficient, and with low sound levels. Breaks down large fans systems into smaller, more manageable fan arrays for added reliability and improved airflow efficiency. FANWALL TECHNOLOGY is ideal for new construction and retrofit applications.

Sound level reduction - Achieve sound levels never thought possible from an air handler with Ventrol's quiet design options. When faced with placing units near occupied spaces or sound sensitive applications, consider a unit equipped with a FANWALL® array and/or sound attenuators to meet your specific sound requirements. Ventrol continues to improve the sound performance of its equipment through use of Nortek Air Solutions's AMCA accredited sound and thermal-testing laboratory, and can offer customers the option of receiving certified sound performance reports.

All the flexibility you need for your HVAC project.
Whether your need is a unique unit configuration, special material of construction, flexibility in installation or demanding performance, Ventrol's engineers have the experience and know-how to design a solution for you. Flexibility and value are what bring customers back to Ventrol.

Custom Air Handlers

Since 1993, Huntair's innovative, custom air handler solutions and FANWALL TECHNOLOGY® have reengineered how we move air. Huntair specializes in HVAC systems used in mission-critical applications, including semiconductor, biotechnology and pharmaceuticals manufacturing, data centers, aerospace, hospitals, and extremely sensitive applications including cleanrooms.

All HUNTAIR air handlers are custom and built to deliver the performance you need for your unique application - providing exceptional value while giving designers the ultimate in flexibility when solving any HVAC design problem.

The ability to provide unique, custom solutions that are simply unachievable using commercial cataloged products differentiates Huntair in air handler replacement and upgrade opportunities. For example, many air handlers installed in the 90's or earlier are near the end of their expected life. The added maintenance to keep them running - or the ticking time bomb of a catastrophic failure - are compelling reasons to replace or upgrade these air handlers. But because they are often tucked away in the bowels of buildings with severe egress constraints, the prospect of a replacement is daunting. In many cases, significant destruction and reconstruction would be required just to remove the old air handler and bring in a like-for-like replacement. In addition to being cost-prohibitive, this approach could cause an unacceptable interruption in your building's operations.

Huntair offers complete solutions to match even the most difficult of your requirements for air handler replacements and upgrades.

Complete Air Handler Replacements

For complete air handler replacements Huntair offers several alternatives depending on the project:

• Modular air handlers are typically delivered in sections that are then assembled on site.
• Knock-down air handlers are first assembled in the manufacturing plant and then disassembled into individual components that are sized to meet the access requirements of the project.
• In cases where space constraints are extremely tight, built-in-place air handlers can be the most ideal solution. 3D modeling of the space allows components to be pre-built to minimize field changes that affect installed cost and timeline.
