Retrofits and renovations present unique challenges for the designer. Venmar CES is there to provide unique Dedicated Outdoor Air Solutions® to help our customers with their most difficult problems.
For tight mechanical spaces, our equipment can be designed go through fixed wall openings, windows and freight elevators. Systems can be designed around columns and fixed opening locations or in modules that can be demounted or entirely knocked down for complete site re-assembly. Individual modules can be fabricated out of specialty materials and designed to a maximum weight to better accommodate helicopter lifts or crane limitations. All of these systems can include a variety of energy recovery technologies and can potentially even be compressorized with minimal field piping required.
For a slightly less customized option, we also offer a variety of classroom ventilators which are ideal for school retrofits and merely require an exterior wall for installation.
Using a FANWALL system to replace older, end of life fans in existing air handler equipment may also be a cost-effective solution for avoiding the cost and business disruption of an air handler failure. Energy savings can be 40% or more. Retrofits using a FANWALL system have occurred in applications ranging from offices, education and hospitality facilities, to facilities with critical requirements such as hospitals, data centers and pharmaceutical manufacturing.
In many cases, access limitations are a barrier to a fan or air handler replacement because it cannot be accomplished without the time and expense of a major tear-out and reconstruction project. A FANWALL system can minimize this and other barriers.
An air handler cabinet can retain its integrity well beyond fans, coils and other components, allowing it to be retained with a new FANWALL system. The modular design of a FANWALL system allows individual cubes to be navigated through a standard 3-foot door and assembled inside the existing air handler cabinet. There is no need to have a crane on site as is often the case with larger, more conventional fans. The performance of the new system can be upgraded to better match actual capacity and airflow requirements.
Ancillary components such as sound attenuators and air blenders that created static pressure penalties in the old system can be removed. Design flaws and other maintenance concerns—such as component access issues and corrosion—can also be addressed, essentially resulting in a new, more efficient air handler in an old skin.
Retrofits often can occur over a weekend or during unoccupied time frames to minimize downtime or disruption of normal business.
