Johnson Controls has a proud history of innovation in both compressor design and variable-speeddrive
(VSD) technology. The Latitude TM series of air-cooled chillers uses the best of modern screw
compressor design and manufacturing techniques and combines them with the latest in a long line
of chiller variable speed drives. The result is superior control and industry leading efficiency at real
world conditions. In addition, by slowing the speed of the chiller to match system requirements at
off-design conditions, the chiller sound output is reduced when it is the most sensitive to neighbors
– evenings and weekends.
With the introduction of the YCIV model air-cooled chiller, system designers have the opportunity to
design around the traditional benefits of air-cooled chillers and still offer building owners the most
up-to-date energy-efficient system design. In the past, the choice to use an air-cooled chiller came
with the expectation of compromise, where simplicity of design and maintenance were traded for
performance and efficiency. Now, installing the Latitude allows for a combining the best of both
worlds can provide a design that truly delivers the lowest total cost of ownership.
