ATK Aerospace Systems (http://www.atk.com) is the world's top producer of solid rocket
propulsion systems and a leading supplier of military and commercial aircraft structures. |
Pnu Power ReGen systems use the same reliable technology as our compressed air batteries to generate power from waste air.
challenge
- convert waste compressed air into electrical energy and feed it back into the electrical supply in periods peak site
demand at ATK’s Launch Systems facility in Promontory, Utah, USA.
- reduce the site’s peak electrical demand periods.
- reduce operating costs, reduce environmental impact.
solution
- one custom built Pnu Power Pnu Power ReGen 480V AC, 20kVA peak shaving system.
- the system comprises a 20kVA rated, ReGen20 v1.0 unit, an automatic air booster
system and a 10 cylinder pack with 300 Bar (4500 PSI) air store.
- the ReGen20 unit is grid connected to the mains electrical supply. Waste compressed is
automatically boosted to 300 Bar (4500 PSI) and stored within a cylinder pack air store.
benefits
- in periods of peak electrical demand, the Regen20 is activated and converts the energy stored within the air store into electrical energy.
- helps to reduce the site’s peak electrical demand periods.
- low maintenance with good, ongoing return on investment.
