Cryogenic tanks for liquid CO₂ (carbon dioxide) 3–60 m³

Cryogenic CO₂ tank ZVT 6 — 5.96 m³ / 6.23 t

Model: ZVT 6SKU: ZVT-6

1 of 5

Vertical vacuum-insulated tank for liquid CO₂ (carbon dioxide): 5.96 m³, 6,234 kg of LCO₂, working pressure 18, 22 or 37 bar. Supplied with piping; price from €31,000 excl. VAT.

A vertical vacuum-insulated tank for 6.2 t of liquid CO₂. Same 1,730 mm diameter as the ZVT 3, so it takes the same footprint and simply stands taller — 6 m instead of 4 m.

Tanks of 3–6 t suit consumers that use up to a few tonnes a month: small bottling lines, breweries, greenhouses and workshops moving from cylinders to liquid CO₂.

What comes with the tank

  • Vessel with piping: shut-off and safety valves
  • Pressure and level instruments
  • Document package and certificates from the European manufacturer

On site you run a line to your equipment or tie the tank into an existing one — weld on the flanges and connect. The vaporizer, pressure-regulating unit, delivery and installation are quoted separately or as a turnkey package.

Foundation and registration

The foundation is designed for the full weight — about 10.1 t for the ZVT 6. We provide the basic data for its design.

The tank arrives with a full document package and all certificates from the European manufacturer. A specialised company issues the pressure vessel passport, and the set is then submitted to the State Labour Service.

Price

From €31,000 excl. VAT. The price depends on the working pressure, the valves and instrumentation, the level and pressure control system and the delivery terms. Delivery, installation, the vaporizer, the pressure-regulating unit and process piping to the consumer are quoted separately.

Key features

  • Holds 6,234 kg of liquid CO₂
  • Working pressure 18 / 22 / 37 bar
