Pentadyne VSS+DC Clean Energy Storage System Earns UL-Listing

Pentadyne Power Corp. announced that its new second-generation VSS+DC flywheel-based clean energy storage systems have earned an Underwriters Laboratories listing.

The UL listing granted – according to the UL website – is based on “basic standards used to investigate products in this category – ANSI/UL 508, ‘Industrial Control Equipment,’ UL 1004, ‘Electric Motors,’ and UL 1248, ‘Engine-Generator Assemblies for Use in Recreational Vehicles.'”

“UL-listing of electrical products like the VSS+DC is critical in the marketplace,” said Pentadyne President & CEO Mark McGough. “It assures building owners and equipment permitting personnel that this product is safe and complies with all applicable national and regional codes.”

Pentadyne flywheel systems supplement or replace hazardous lead-acid battery arrays used with uninterruptible power supply (UPS) systems. Chemical battery banks require extensive, costly and lengthy permitting processes due to their corrosive materials, fire hazards, toxic fluids and explosive gas emissions.

“Complying with building and electrical code requirements is key to the VSS+DC’s ease of installation,” said Frank DeLattre, Pentadyne’s Senior Vice President of Sales & Service. “Unlike competing products that require reinforced flooring, extensive bracing and other site requirements that add cost and time, the lightweight, compact VSS+DC can be simply rolled into place and commissioned in less than one hour. That type of appliance-like installation ease, safety and speed is yet another advantage of the Pentadyne product.”

Pentadyne claims that its flywheel power system improves UPS reliability by completely replacing or greatly extending the life of lead-acid batteries commonly used in most UPS configurations. In comparison to batteries, the VSS+DC improves UPS reliability while eliminating costly ventilation and cooling requirements as well as reducing lifecycle cost and maintenance/replacement needs. With a much smaller footprint than an equivalently sized battery system, the VSS+DC saves valuable floor space in the data center leading to higher computing density.
