Commitment to the Environment
Air Compressor Upgrades
In 2008 a variable frequency drive air compressor was installed at the Nazareth facility. This replaced the oldest of three original 150 hp air compressors. This compressor ties into the duct work above it, converting the exhaust air to heat for the Martin Guitar mechanical room during the winter months and hot water for heating office areas throughout the entire year.
A 50 hp variable frequency drive air compressor was installed at Martin's Navojoa, Sonora, Mexico manufacturing facility in 2005. This installation served as the prototype for the 150 hp version installed in Nazareth. A second 50 hp variable frequency drive air compressor is scheduled to be installed in Navojoa in Fall 2010.
In 2008 the roof covering the Martin Guitar finishing area was replaced with a new thermoplastic polyolefin (TPO) membrane. TPO membrane is energy efficient. Its white surface reflects the sunlight and reduces building cooling costs. TPO membranes are chlorine-free, and their heat-welded seams further contribute to the system's environmental friendliness.
By September 2009, 36% of the roof at Martin Guitar's 510 Sycamore Street facility was replaced using the same TPO membrane material.
Finish Curing Room
With the assistance of an outside consultant, a finish curing room was configured, tested and implemented in January 2010 in Nazareth. During the configuration the energy cost impact of the project was carefully considered. To minimize energy costs, several key features were incorporated into the project:
- A heat pipe energy recovery coil captures heat from the exhaust air stream and uses that heat to preheat the incoming outside air. The system can recover free heat on any day that the outside temperature is less than the room operating set point.
- Instrumentation monitors total VOC levels in the space on a continual basis. The ventilation airflow rate automatically modulates to maintain the tVOC levels at acceptable levels. This will allow for reduced ventilation rates and corresponding energy costs when tVOC emissions within the room are less than the design criteria.
- The system was designed to minimize air friction, thereby minimizing fan energy consumption.
- Motion controlled T5 high output (T5HO) lighting automatically turns off when the room is unoccupied.
Overall, the operation of the new finish curing room minimizes energy use. The energy recovery device within the finish curing room will save over 10,000 therms of natural gas per year, equating to more than 60 tons per year reduction in CO2 emissions.
