VS–DSS SERIES
VERTICAL DISTRIBUTOR STORAGE SYSTEM
Chart’s VS-DSS (Distributor Storage System) Series of vertical
bulk storage stations are engineered for superior
performance, durability and value. Equipped with our
proprietary Composite Super InsulationTM (a light-weight
system offering better thermal performance than Perlite), the
VS-DSS series provides reduced product losses and a slower
rate of pressure rise during periods of non-use. Backing up
this performance is a competitive 2-year vacuum warranty.
Available in the 1500, 3000, and 6000 gallon (5700, 11,400, and
23,000 liter) models, the VS-DSS series features the industry
standard thermal performance. The modular plumbing
system has been selectively optimized to meet the flow
requirements of a complete range of liquid or gas
applications. With a comprehensive set of plumbing features,
each circuit has been carefully designed to match the
demands placed on these vessel sizes. Dual safety relief
devices are standard, and tank mounted vaporizers are
optional on 1500 gallon sizes.
PRODUCT ADVANTAGES
• Sizes, pressures and configurations to meet most
applications
• Backed by our standard 2-year vacuum warranty
• Leg design provides better access to anchor bolts for
quicker installation
• Lower tare weight reduces freight and pad costs
• Long-life urethane paint system
• Plumbing built in accordance with ASME B31.3 code
and leak tested at 1.1 times the MAWP
• Inner vessel designed and built to ASME Section VIII
Division 1 code
