Below are some of our most notable projects.

	Tennessee Valley Authority - Paradise Fossil Plant Flue Gas Desulfurization Duct & Freeze Protection Project: Triangle partnered and provided the HVAC, process ductwork insulation & lagging, process piping insulation, heat tracing and scaffold support for this FDG system serving a 1350 MW coal fired unit in central Kentucky. This project was completed on time and without any lost time injuries or restricted work days. The projects were performed under contracts to Bowen Engineering and Advatech, LLC.
	Tennessee Valley Authority - Cumberland Fossil Plant Control Bay Pressurization and Chiller Replacement: This $1.8M project scope involved the installation of two 250 ton chillers, a 56 ton 100% outside air make-up system, numerous air handlers, complete powerhouse chilled water piping replacement, ductwork, controls and insulation. The scope also included all structural steel platforms, 6.9kV and 250V power and associated switchgear. All the work was performed without interruption to normal plant operations.

	Tennessee Valley Authority - Kentucky Lake Hydroelectric Dam Building Controls and Life Safety Upgrades: The project scope included the change-out of an 80 ton chiller and the replacement of pneumatic controls with a complete Honeywell DDC system including control damper replacements. The life safety portion included installation of multiple fire dampers, pressurization & exhaust fans and controls. The work was completed in three phases in order to allow uninterrupted cooling and control to the customer.

	Ameren - Grand Tower Station Re-Powering Project: Two Westinghouse gas turbines were added to turn two new generators and each turbine's exhaust was recovered in HRSG units which generated steam to drive the two existing generators. Triangle was responsible for the insulation and sheet metal work on this nearly $9M project performed under contract with J. A. Jones of Charlotte, NC.

	Massac County High School HVAC Replacement and Upgrade: This project was performed under an accelerated schedule. The entire job was completed during a 12 week period (summer break). The project included 3 package units (70 tons total), 170 tons in 63 water source heat pumps, 4 energy recovery ventilation systems, a cooling tower and a boiler. All the domestic water piping was replaced.

	Arkema - Refrigerant Plant Insulation project: This project consisted of 12,000 liner feet of process piping and numerous pieces of equipment utilizing mostly Foamglas insulation and stainless steel jacketing. Custom removable blanket fabrication and scaffolding support were also provided.

	Best Buy of Paducah, Ky HVAC Project: This picture shows 1 of 10 air conditioning units being set by a crane at the Kentucky Oaks Mall located at Paducah, KY. The roof top units ranged from 2 to 17.5 tons. We were also responsible for the ductwork servicing the building.

	Southern Illinois Power Coop - Marion, IL Unit 4 SCR Addition: Triangle performed the insulation and lagging portion of this project located at Marion, IL. This photograph records the SCR diverter duct's lift into position. As you can see the duct was insulated and lagged on the ground as were all the other ducts and SCR sections. Field joints were finished after the pieces were erected. This project was performed with J. S. Alberici of St. Louis, MO

	Marshall County Peak Power Station - Calvert City, Ky Peak Power Plant: This facility was built near Calvert City, KY for Duke Energy. Triangle's portion of the work included lining the exhaust stacks and insulating piping and six large tanks. The demineralized water storage tank is shown in progress. This tank is 77 feet in diameter and 48 feet tall. This picture was taken before the aluminum lagging was applied.
