Micro Bulk Tank on Lease

If your operation is burning through six, ten, or twenty liquid cylinders a month, the hidden cost isn’t the gas; it’s the labor, the forklift time, the empties-out-fulls-in dance, and the production that pauses every time a cylinder runs dry. A micro bulk tank on lease from FireCryo replaces that chaos with stationary on-site storage, automatic refills, and uninterrupted supply. Compact, cost-efficient, and right-sized for labs, small manufacturers, clinics, and production cells. Family-owned in Texas since 1974, we’ve been solving this exact problem for half a century.

THE CYLINDER PROBLEM EVERYONE JUST PUTS UP WITH

Running a facility on liquid cylinders means somebody’s job is cylinders. Ordering them, tracking them, signing for deliveries, swapping empties, documenting the rotation, and making sure the line doesn’t run dry at 2 a.m. on a Friday. The cost multiplies: delivery fees, demurrage on cylinders sitting too long, lost production during swap-outs, and gas lost during connect/disconnect. Small and mid-scale operators often accept this as “just the way it is.” It isn’t. For steady gas users pulling 4–6 liquid cylinders a month, onsite gas storage solutions typically cost less per liter and eliminate the need for swap-out labor entirely.

AVAILABLE MICRO BULK TANK CONFIGURATIONS

Our mini cryogenic tank lease fleet covers the full micro bulk range used by U.S. operators:

230L and 265L Portable Units

DOT-rated caster-base units with LCCM regulators. True "pick it up and roll it" portability, ideal for labs and small process cells. Gross capacity 61–73 gallons.

450L and 700L Plate-Base Units

Stationary compact installations for small manufacturers and clinics. Available in HP (350 psig) and VHP (500 psig) configurations for higher-pressure gas-use applications.

1,000L to 3,000L Pallet-Base Tanks

The core of the micro bulk range for steady industrial gas users. Pallet-based design for forklift positioning. HP/VHP dual options; gross capacities from 279 to 770 gallons.

5,500L and 7,000L Larger Micro Bulk

Where micro bulk overlaps with small bulk. Up to 1,840-gallon gross capacity on a pallet base.

Perma-Max Style CO2 Units

12,000-lb CO2-specific micro bulk for beverage, food, and industrial carbonation applications.

INDUSTRIES WE SERVE

A small liquid nitrogen tank rental or a micro bulk LOX/LAR/CO2 setup works for any operation that uses 4+ liquid cylinders a month. Our customers include:

Industrial Gas Distribution

Rotate leased tanks and trailers through your customer base to cover new contracts, replacement cycles, and peak demand without tying up capital in owned fleet.

Research Laboratories

LN2 for sample storage, cryopreservation, dewars, and BSL-equipped cleanrooms.

Small Manufacturing & Fabrication

Argon and nitrogen for MIG/TIG welding cells, laser cutters, and brazing ovens.

Biotech & Pharma

LN2 for cell banking, vaccine storage, and critical cold chain.

HOW THE LEASE PROCESS WORKS

Moving from cylinders to micro bulk shouldn’t be difficult. Here’s how FireCryo runs it:

1

Usage Assessment

Talk to Julie or Jolene about your current monthly cylinder count, the gas, your peak draw rate, and the space you have available.

2

Tank Sizing

We recommend a tank sized to give you 2–4 weeks between fills, not so small you're ordering constantly, not so big that liquid holds too long and boils off.

3

Tank Match

We pull from our own fleet first. Julie's dealer network sources unusual configurations (VHP, CO2 Perma-Max, or manufacturer-specific) when needed.

4

Site Coordination

We verify the installation spot (indoor or outdoor), adequate ventilation for LOX service, and forklift access for pallet-based units.

5

Delivery & Support.

Tank arrives ready for fill. Ongoing vacuum service, valve repair, and swap-outs are one phone call away.

FLEXIBLE RENTAL OPTIONS

A mini cryogenic tank lease should match how your operation actually uses gas. Our terms flex accordingly:

  • Short-term rental — by the month for project-based work, seasonal production, and pilot runs
  • Long-term leasing — multi-year terms for steady production users where rates stay locked in
  • Capacity scaling — start at 450L, swap up to 1,500L or 3,000L as usage grows, without buying new equipment
  • Emergency deployment — when a cylinder supplier lets you down, a micro bulk tank can be on-site within days
  • Multi-tank setups — multiple smaller tanks distributed across a facility for cell-specific supply

REAL-WORLD APPLICATIONS

Micro bulk earns its place in operations where cylinder handling is eating labor hours or limiting production:

Laboratories and Research Facilities

A 450L or 1,000L microbulk gas system replaces 15–40 liquid cylinders per month for sample storage and cryopreservation, with automatic refill scheduling via a gas supplier's Orca-style delivery route.

Food and Beverage Operations

Craft breweries running LCO2 Perma-Max skid units instead of cylinder manifolds, eliminating weekly swap logistics during peak production.

Small Manufacturing Cells

Welding and laser cutting operations running 700L or 1,500L argon micro bulk for shielding gas, with better flow consistency than cylinder manifolds.

Medical & Healthcare Facilities

Surgery centers using micro bulk LOX for reliable supply without the cylinder swap traffic at the loading dock.

FREQUENTLY ASKED QUESTIONS

A rough guideline: if you’re currently going through 6–15 liquid cylinders a month, a 450L or 700L usually fits. 15–30 cylinders point to 1,000L–1,500L. 30+ cylinders, look at 2,000L–3,000L. Call us with your actual cylinder count, and we’ll size it precisely.

Liquid nitrogen, liquid oxygen, liquid argon, liquid CO2, and N2O are standard. CO2 units are typically Perma-Max-style construction built specifically for liquid CO2.

Yes — most micro bulk tanks are rated for indoor or outdoor installation. Adequate ventilation is required (especially for LOX service to manage any oxygen enrichment risk).

Depends on usage. Most operators plan for 2–4 weeks between fills. Your gas supplier handles refills through a scheduled route.

Liquid cylinders are 180L–230L portable dewars that you swap when empty. Micro bulk tanks are 230L–7,000L stationary storage tanks refilled in place, no swap-outs.

 No hard minimum. Monthly short-term and long-term leases are both available.

FireCryo provides dependable cryogenic equipment leasing and sales across the U.S., delivering high-quality tanks and reliable, ready-to-deploy solutions.
