Research Project Summary Information
Variable-volume Closed Loop Dust Collection System at Steinway(ST10817-1)
Steinway & Sons has a mandate to condition designated manufacturing areas for better control of humidity in order to optimize the moisture content of various wood components of the pianos being constructed. Currently they are the demonstration site for Energy Resource Solution’s (ERS’s) Solar Thermal Cooling project, co-funded by NYSERDA. This project impacted the sizing requirements of the Solar Thermal project as the existing constant volume open-loop dust collection system adds considerable cooling/heating loads to the facility by exhausting conditioned air.
The project demonstrated a dust collection system using variable-volume control in combination with a closed-loop (recirculation) system. Steinway replaced the entire Action Department dust collection system (35% of the energy consumption of the existing systems).
Reduced kWh consumption associated with efficient VFD control. Reduced natural gas consumption due to closed-loop recirculation; lower emissions; reduced carbon footprint; improved product quality and productivity.
The system was installed in the Action Department and became operational in late 2008, with debugging and commissioning occurring through the Spring of 2009. The primary benefits of the system are improved dust control, expansion capability, and lower energy consumption ($58,000 per year in electricity and gas savings).
