Description

This is the smallest tank most installers will bother to set permanently, and the point at which owning beats renting a cylinder.

Typical loads are a standby generator, a shop heater, a range, or a dryer on its own supply.

Filled to the 80% limit this vessel holds about 96 gallons of propane — roughly 9 million BTU, or about 407 lb of product. On a 30,000 BTU/hr appliance that is around 293 hours of burn time from a full fill.

In our range it sits between the 100 gallon and the 200 gallon. If the load is borderline, the 200 is the safer buy and the freight is the same either way.

Specification

  • Shell capacity: 120 gallons
  • Propane held at the 80% fill limit: approximately 96 gallons
  • Mass of propane at full fill: approximately 407 lb
  • Energy held when full: approximately 9 million BTU
  • Installation: Underground (buried)
  • Certification: ASME stamped
  • Condition: Confirmed on your invoice
  • Fuel: Propane / LPG

Siting and installation

Below-ground installation needs a hole, clean backfill free of anything that will abrade the coating, and cathodic protection sized to the soil. Get those three right and the vessel disappears from the property and from the maintenance schedule.

Setting and commissioning must be done by a licensed propane professional in line with NFPA 58 and local code. Ask us if you need a name in your area.

Condition and documentation

Whether new or certified used, nothing ships without a live stamp, a passed pressure test and the documentation to prove both.

Service valve, fill valve, relief valve, float gauge and vapour connection are all checked before dispatch, and anything that does not pass is replaced rather than nursed along.

Before you order

Tell us the delivery ZIP when you enquire and we will quote the tank and the freight in the same reply, including any access surcharge — not after you have paid.

Check your local clearances before ordering. Setback distances from buildings, boundaries and ignition sources are set by code and they decide where — and sometimes whether — a given capacity can go.

Talk to the sales desk

Tell us the load and the ZIP. We will quote the tank and the freight together.

No call centre and no quote-chasing — you get a real figure, in writing, from someone who knows what a lift gate costs in your county.
