Project Name: Savannah College of Arts and Design (SCAD)
Location: Savannah, GA
Challenge:
The Savannah College of Arts and Design (SCAD), located at 342 Bull St., Savannah, GA flagship building was originally named Preston Hall. Poetter Hall dates back to 1892, when it opened as the Savannah Volunteer Guard Armory. This 36,248 square-foot building contained a drill hall, ballroom, large company rooms and a guard club. Poetter Hall was the first building that SCAD acquired in 1979. The historical building includes deep arches, massive corner towers and ornate wrought iron balconies.
Bringing fresh air into historical buildings such as the SCAD building can be challenging for HVAC installers. Often there is not enough room to mount a unit on the roof and if you could, it probably would not be visually pleasing. When it comes to accomplishing this task, there is no better solution than installing a United CoolAir unit.
Solution:
In order to provide an outside air solution, Mingledorff’s of Norcross, GA was able to specify and install a 7-ton OmegaAir unit with a remote outdoor condenser. Traditional HVAC systems are designed primarily to handle design sensible loads and are not adequately designed for the high latent loads produced by OA. The OmegaAir is designed to exclusively handle the large latent ventilation load and deliver “neutral” air of 70ºF to 72ºF @ 50% RH. OmegaAir’s supply air dew point design temperature is lower than standard air conditioners to remove the maximum amount of moisture before delivery to the space.
Project Name: PSERN (Puget Sound Emergency Radio Network)
Location: King County, WA
Challenge:
PSERN, is a state-of-the-art land mobile radio communication system providing voice communication and limited data capabilities. The station primarily serves police, fire, and emergency medical service personnel in the performance of their emergency response duties. The mobile station needed equipment cooling on a year-round basis. Unfortunately, the peaked roof of the building was unable to support a rooftop unit. Since most HVAC manufacturers primarily make rooftop units, it was difficult to find a unit that would fit in the attic.
Solution:
The operators of the mobile station would soon learn that units were coming to the rescue. United CoolAir was able to provide two 4-Ton C-13 horizontal air source heat pumps. As a precision cooling unit that included an airside economizer, the controls contractor was able to apply their own controls to provide a lead/lag sequence and staging of compressors.
Project Name: New England Merchants Bank Building

Challenge:
28 State Street is a modern skyscraper in the Government Center neighborhood of Boston, MA. This 40-floor structure is Boston’s 18th-tallest building. It has been known as the New England Merchants Bank Building and the Bank of New England Building. Recently the building owner needed to replace 9 Trane® SWUD units of 52 tons that had reached the end of their ability to perform. Though the old Trane® units could be dismantled and removed, there was a challenge of finding replacement units that did not require demolition to the tower.
Solution:
New England Applied Products was able to replace the old Trane units with 9 new 52-ton United CoolAir Renovators. The UCA Renovator was built as an answer for the many Trane® SWUD units that need replacement. 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. As an added benefit, these units are more efficient than the units they replaced by the use of a waterside economizer and quiet ECM fans.
Project Name: Wells Fargo
Location: Raleigh, NC
Challenge:
A Wells Fargo bank in Raleigh, NC had three 46 Ton Trane SWUD units that had reached the end of their lifespan. In their search to find a replacement unit, it was difficult to find an HVAC unit that would fit the exact footprint of the existing SWUD’s without having to perform costly demolition of the building structure. For instance, in order to prevent disruptions for the 70% occupied building, the replacement had to occur quickly.
Solution:
The timing could not have been better for the bank, as United CoolAir has the VariCool Renovator, a direct replacement for Trane® SWUD units ranging from 42–80 Tons. To begin with, these self-contained water-cooled units shipped in multiple sections, fitting through the doorway and easily into the space.

Project Name: Trenholm Church
Location: Columbia, SC
Challenge:
The Trenholm Road Methodist Church was tasked with replacing outdated chilled water and dehumidification HVAC systems. The outdated system had been in place since the building’s construction. Located in the hot, humid climate of South Carolina, conditions within the church become even more intolerable during Sunday services or during church events when the number of people and events would increase.
Solution:
The contractor chose a VRV system for better zoning control because the church is divided into 7 unique zones. They decided to use United CoolAir Corporation’s OmegaAir dedicated outside air systems (DOAS). The VRV units do an excellent job of controlling the sensible temperature in each zone but have limited dehumidification capability. The OmegaAir DOAS, on the other hand, is designed specifically for OA delivery. Using an OmegaAir allowed them to separate the sensible and latent loads for best performance. A total of 7 DOAS units were specified, one for each zone. To tie it all together, the VRV and DOAS units were tied into a BAS for precise control and management. Overall, the cooling requirements for the entire project were 62 tons.
