VariCool Renovator

In past decades the Trane® SWUD unit was the preferred unit when someone wanted a Variable Air Volume system. So to date, there have now been thousands of these units installed in the United States. Starting in the 1980s and ‘90s, if someone needed a Constant Volume System unit they turned to Trane®. However, a common practice was to place the SWUD units inside mechanical rooms, but while the building was under construction. Now years have gone by and the Trane® SWUD units are reaching the end of their lifespan. Therefore, this presents a problem as well as an opportunity.
This has made replacing the SWUD units very hard to do because they are enclosed inside walls. Usually, it is very tough to bring in a replacement unit once the SWUD unit has been removed. In order to complete this task, it involves demolition to walls or the roof. The cost and logistics to replace SWUD units can be huge and lead to much frustration to the end-user.
The UCA Renovator was built as an answer for the many Trane® SWUD units that are in need of replacement. In particular, 42 through 80 ton Trane® SWUD units are replaceable by the VariCool Renovator. These self-contained water-cooled units ship in several sections. Furthermore, they fit through a standard 36″ door or smaller while keeping their original factory charge. The Renovator maintains the original SWUD footprint while simultaneously removing the cost of rigging, permits and tenant disruptions. This results in cost and time savings for end-users.

VariCool EZ-Fit

The VariCool EZ-Fit is a self-contained, modular air conditioning system for use with floor-by-floor variable air volume uses. The unit’s engineering and manufacturing are exactly for this purpose. So as a result, it is perfect for installation/renovation for retrofit jobs. This offers the ultimate All-Indoor Solution for challenging HVAC applications.
This design contains three distinct sections so that they easily join to form a single unit. The unit consists of a fan section, evaporator coil section, and a condensing section. Single modules are available in 12–15 ton, 20–25 ton, 30–35 ton, and 40–45-ton sizes. Dual modules then form together systems as large as 90 tons of cooling.
The manufacturing process includes evacuation, charging and testing before the final assembly. Using resealable refrigerant fittings allows the unit shipping split but without losing the factory charge. All module sections use inventive 3D-Intelliclamp connectors so that the units can be joined together. This results in a perfect component alignment but with lower installed cost without any loss of system reliability.
