Buildings and plants that have chilled water systems depend on efficient operation of that equipment. Inefficiency means higher utility cost. Most operating chilled water plants have many opportunities for savings. New plants should be designed and commissioned to operate with efficiency. Our knowledge of hydronics, controls, and commissioning allows us to optimize a chilled water system for ideal operation and minimal operating cost.

Since our first four-chiller plant in 1995, Applied Engineering has specialized in central plant design and is now renovating some of those past projects. Following are recent examples of completed central plant projects.


Rockford Manufacturing, Rockford, TN (Commissioned 2020)


This Rockford, Tennessee based textile manufacturer has been in operation since 1854 and is the oldest continuous operating industry in Tennessee. Their existing plant chillers were approximately 35 years of age and needing replacement. Two new air-cooled chillers, 500-tons each, were installed on the plant roof and the plant chilled water piping was renovated for the new service. Polypropylene piping was used on the roof to minimize weight. A new control system was added in the equipment room and controls for the four plant air washers were networked together.

Volunteer Mechanical was our partner in construction.


Denso Manufacturing Building 101, Maryville, TN (Commissioned 2018)


After 27 years of operation, the air handling units for the 600,000-square foot Building 101 were showing some age. While the custom-built units were still in good condition, the condensing sections were reaching the end of their life. Applied Engineering was selected to renovate these air handlers with chilled water coils and add a new 3,200-ton chiller plant to the facility.

The chiller plant featured five, 500-ton chillers and 700 effective tons of ice storage tanks, selected to maximize the use of off-peak electric rates and reduce the cost of electric use. Another cutting-edge feature was the use of polypropylene piping, located on the roof of the facility. Over 7,500 feet (1.5 miles) of piping was installed, avoiding interruptions to plant production, and reducing weight on the roof.

The plant was designed for a minimum temperature difference of 19 degrees and was successfully operating at a 21-degree difference after initial commissioning.

Del-Air Mechanical was our construction partner.


Denso Manufacturing Building 202, Maryville, TN (Commissioned 2019)


As part of an effort to support automotive instrument cluster production, Denso found that additional process chilled water capacity was needed. A two-chiller, air-cooled, 220-ton plant was located at grade level, complete with primary pumps and controls. Chilled water piping was polypropylene plastic for light weight. The piping was routed to the plant roof where it was tied into an existing process water loop.

Del-Air Mechanical was our construction partner.


Adler Pelzer Automotive Group, Athens, TN (Commissioned 2020)


After participation in the initial 2013 plant design, Applied Engineering was again asked to be a part of a construction team tasked with expanding the existing plant. While the 53,000 square-foot expansion was modest, it required a significant renovation to the existing process chilled water system. A new 40-ton process chiller was added to the existing 140-ton plant. In addition, pressure independent balancing and control valves were added to each of 54 hydraulic press locations.

Shoffner Kalthoff Mechanical was our construction partner.


Colortech Plant Two, Morristown, TN (Under Construction)


Colortech’s Plant Two location/property was purchased in 2013, a plant that had been designed by Applied Engineering in 1998. The chilled water plant, 500 tons, was ready for replacement and additional capacity was required to meet manufacturing goals. A new, 700-ton air-cooled plant was located on grade at the opposite side of the building from the existing chillers. New pumps and hydronic equipment were located indoors, and a new control system for the plant was integrated into existing building controls. The control system was designed to optimize the process and HVAC cooling loop(s) temperature difference for maximum efficiency.


Office building and retail spaces require space conditions and mechanical design that is consistent with the tenant’s business and functional requirements. Our ability to coordinate with architectural and interior design concepts sets us apart from many others. Energy efficiency remain a high priority for these projects.

Our experience in the education field is deep and includes many large, institutional university buildings. Knowledge of central plants, building automation, and specialized applications like steam distribution are important. Experience in construction administration is especially important, to document and manage processes that are more complex than many smaller projects. A good relationship with building officials is an asset, and knowledge of their requirements allow quick turnaround of reviews when needed most. Applied Engineering accepts projects where code compliance is valued and achievement of indoor air quality is supported by Owners.
