Contact your local Ventrol Representative to find a custom solution for your HVAC application.

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.     

Knock-down construction means that the unit is engineered and manufactured for disassembly prior to installation.  Extra attention is given to the break points of the unit for easy disassembly and reassembly in tight mechanical room spaces. The unit can arrive at the jobsite broken down or can be disassembled on the jobsite. Contractors can visit our factory to see how the unit is manufactured to make jobsite assembly a breeze. 

A popular option in retrofit applications is for a unit to ship complete for disassembly at the jobsite or to ship disassembled on a pallet.  Knock-down construction may also include:

• Factory marking of break points
• Fasteners designed for disassembly and reassembly
• Extra insulation and fasteners
• Factory supervised installation
• 3-D drawings and assembly instructions

Getting equipment into tight places is no longer a problem when you specify knock-down construction from Ventrol.  Contact your local Ventrol Representative to show you how knock-down construction may be the best solution for your facility needs.

Thermal Break Technology

When sweating or frosting on the exterior of your air handler is a concern, Ventrol offers several thermal break technologies to mitigate this concern. The objective of putting a thermal break into a panel construction is to minimize or eliminate any condensation and frosting on the warm side of the panel caused by thermal bridging. This is done by placing a material with significantly higher thermal resistance in the critical bridging path. It forces the largest temperature difference to occur across this material, raising the surface temperature on the warm side.

Applications that require a thermal break have relatively high temperature differences across the surfaces (temperature differential of 50˚F or greater) and/or a low discharge air temperature when cooling. For these situations, a thermal break is important due to the possibility of condensate forming on the exterior of the cabinet which may damage an interior space. Liquid condensation can be much more of a problem with indoor units located in unconditioned space and designed for air conditioning applications.

Ventrol has several innovative thermal break solutions including varying thicknesses of fiberglass insulation up to 4-inches, hybrid foam panel, injected foam panel, and polymer joiners.

FANWALL TECHNOLOGY

Unlike other fan arrays available today, a FANWALL^® system is more than off-the-shelf fans and motors arranged in an array. It incorporates FANWALL TECHNOLOGY—innovated and manufactured specifically for fan array systems—to create an integrated system of state-of-the-art fans, motors, cabinetry, controls, and accessories. These components have been successfully blended to match new construction and retrofit application requirements, while providing:

• Redundancy
• Quiet and vibration-free operation
• Optimized energy efficiency from design minimum to maximum flow
• Low cost maintenance and service

Since 2003, more than 40,000 FANWALL cubes have been installed and are successfully moving over 250 million cfm throughout the world. Applications for FANWALL TECHNOLOGY range from office, education and hospitality facilities, to facilities with critical requirements such as hospitals, data centers, and pharmaceutical manufacturing.

FANWALL TECHNOLOGY originated from HUNTAIR^® ceiling grid systems used in cleanroom applications. The smaller fans and motors distributed throughout the grid are ideal for providing the even airflow distribution required for a cleanroom environment, a compact footprint for ceiling mounting, as well as redundancy and easy serviceability to minimize revenue risk associated with downtime.

These same benefits can also be applied to any air handler system, particularly where a critical failure would result in significant risk to capital equipment or revenue losses. However, the characteristics and constraints of an air handler cabinet differ from a cleanroom environment, requiring significant R&D before the concept would become the reality of FANWALL TECHNOLOGY. In doing so, HUNTAIR examined every aspect of the individual fan cubes and their interaction together—throwing out the book on conventional fan metrics to design a completely new system optimized for fan array applications, including:

• Custom fan wheel designs and inlet cones to optimize airflow efficiency and minimize turbulence. The fan wheels are AMCA certified at 72% efficiency, which is 7% to 9% higher than comparably sized fans offered by others and equivalent to much larger fans.
• Multiple fan wheel sizes and motor combinations to provide flexibility in meeting airflow requirements and create an even piston of air within the constraints of the air handler cabinet dimensions. Fans are available in seven sizes from 10 to 22 inches to closely match airflow requirements. Expanded horsepower (hp) motor selections provide the ability to closely match the design hp for peak efficiency throughout the operating range of the air handler.
• A robust cube design and silencing system (called a Coplanar Silencer^®) to minimize sound and vibration.
• Damper selections to minimize pressure drop and block-off plates that eliminate backdraft air in fans that are off.
• Control algorithms to optimize performance in variable airflow applications.

Sound Reduction Technologies

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’s high performance air handler designs take acoustical performance into account—from product and system design to installation. To verify that the acoustic performance of our product designs will meet the requirements of your applications, CES Group, LLC built its own AMCA 300 accredited sound lab facility for HVAC products ranging in size from 500 to over 65,000 cfm. The lab provides a wide range of unique services to customers and each CES Group^® company, including acoustic modeling, witnessed production testing, and robust performance and diagnostic analysis. The lab is also the site of rigorous, ongoing R&D testing designed to continually enhance and improve the entire product line of each CES Group company.
