VariCool Renovator

During the 1980’s and 90’s, Trane SWUD units were installed in thousands of buildings throughout the USA. In most cases these Variable Air Volume and Constant Volume Systems units were installed while the building was being erected and the walls were built around the units enclosing them inside mechanical rooms or other hard to access spaces. Now years have gone by and the Trane SWUD units are reaching the end of their lifespan. This presents a problem as well as an opportunity. While the old AC units can be disassembled and removed, it is quite another thing to bring in a suitable replacement unit. Building managers are routinely told they need to demolish an outside wall or roof and hire a crane to accomplish the replacement task. The expense and logistics to replace the Trane SWUD units can be enormous leading to much frustration to the end user.

The United CoolAir Renovator was developed as a solution for the numerous Trane SWUD units that are in need of replacement. The Renovator is designed to be a direct replacement for Trane SWUD units 42 through 80 tons. These self-contained water-cooled units are shipped in multiple sections and fit through a standard 36″ door or smaller, all while maintaining their original factory charge. The Renovator maintains the original Trane SWUD footprint while simultaneously eliminating the cost of rigging, permits and tenant disruptions, resulting in cost and time savings for clients.

VariCool EZ-Fit

The VariCool EZ-Fit is a self-contained, modular air conditioning system for use with floor-by-floor variable air volume applications. It is engineered and manufactured specifically for installation in renovation and retrofit projects and provides the ultimate All-Indoor Solution for challenging HVAC applications.
The VariCool EZ-Fit design consists of three distinct sections that easily mate to form a system module. The module 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 together form systems as large as 90 tons of cooling.

Sections are assembled during manufacturing and evacuated, charged, tested, and then separated for shipment of individual sections. The use of resealable refrigerant fittings allows the unit to be shipped split without losing the charge. All module sections are joined together using innovative 3D-Intelliclamp connectors which ensure perfect component alignment. The result is a lower installed cost without any sacrifice of system reliability.
