Geothermal Vaults and HDPE Structures
What is a Structure?Valve Vault ManholePump StationCatch

these have been made from HDPE by ISCO Industries
Advantages of HDPE StructuresThey are the same as the
pipe:ToughFlexibleLeak-freeLightweight and easy to installCorrosion
& Chemically resistantHDPE structures can be prefabricated for
installation savings and higher quality.
Design ElementsHeader/Circuit size# of CircuitsLocation of
CircuitsCircuit ValvesHeader ValvesManwayMisc
Header and Circuit configurationHeader size is typically 4-10
which does not affect cylinder diameter# of circuits and location
of circuits will affect length
Location of CircuitsStandard configuration is for circuits to
come out both sides of vaultsCan offer circuits to exit one sideCan
create unbalanced number from one side to other
Valves for VaultStandard Valves typically butterfly
valvesBalancing valves and circuit setters availableBall valves for
purge ports only- not recommended for circuitsTypically provide
butterfly valves for main shutoffNew Bypass recirculation
Manway designStandard Bolted Cover H-20 load bearing
availableVariable diameter with 28 OD standardHeight can be
specified- shipping concerns become a factor with excessive
height
Miscellaneous ItemsLadder (standard)P/T ports

Miscellaneous ItemsSumpPumpPressure GaugesThermometersDrain
Valve for circuitsKeep in mind this vault is not a mechanical
room.
Factory Tested for LeaksHeader and Circuit piping
hydrostatically tested to 100 psiStructure tested with 2-3 psi of
air to verify vault sealed from groundwater and weather.Misc items
like sump/pump become unessential if liquid in interior comes from
upset conditions, not standard conditions.
Installation ValueLightweighttypically less than 5000 lbs
Maximum of 15000 lbs for 36 circuits
Installation ValueFast installCompared to alternate choices,
time is measured in hours verses days/weeks
Installation ValueSimple and Reliable ConnectionsCircuits and
headers are connected to stubs on vault with Butt Welding or
Electrofusion
Years of Design and Fabrication experience can help prevent
installation and operation headaches.Choose an ISCO Circuitmaker
Vault for reliable strength and leak free performance!
