A food fulfillment center's demand outgrew its building. A rented ZSTORE 3XL freezer added capacity, picking room and the option to grow.
In This Article
A food fulfillment center in Sacramento, CA saw demand growing faster than its building could keep up. It needed capacity now, room to pick orders, and a solution that could grow with it. A freezer storage rental delivered all three: a mobile ZSTORE 3XL, with the option to add units as volume keeps climbing.
The challenge
Frozen fulfillment is space-hungry. Product has to be stored, orders have to be picked, and both have to happen at freezer temperature. When demand grows faster than the building, the freezer is usually the first thing to fill up.
This company had three needs at once:
- Capacity now, not after a construction project.
- Room to pick orders, not just shelf space.
- A path to grow as volume keeps rising.
Capital was part of the equation too. Money spent on a permanent freezer is money not spent on growing the business, and a fixed room can be outgrown just as the building was.

The solution
ZGROUP supplied a mobile ZSTORE 3XL on rental. Three ZSTORE XL modular cold storage modules connect side by side into one open freezer of 960 ft², large enough to store product and pick orders in the same space.
The rental model meant no capital expense. And because the system is modular, the company has the option to add units as volume keeps climbing, instead of replacing what it has.
Picking room is the detail that often gets missed. A freezer packed wall to wall with pallets stores product, but it slows fulfillment. An open walk-in lets the team store and pick in one place.
The results
- 960 ft² of floor area
- Freezer for frozen storage
- No CAPEX with a mobile rental
The fulfillment center gained frozen capacity and picking room right away, with a clear path to expand. When volume climbs again, the answer is another module, not another building.
When does freezer storage rental make sense?
Freezer storage rental is a strong fit when demand is growing but the long-term picture is still taking shape. It lets you add capacity quickly without tying up capital in a permanent build.
- Growth is fast or uncertain. Modular units scale in steps. Each ZSTORE XL module adds 320 ft² and about 20 pallet positions.
- You need it soon. ZGROUP delivers in under 60 days and installs in 2 to 5 days, with no civil works.
- You may move. Units can be moved and reinstalled at another site.
- You need more than one temperature. Zones can run at different temperatures, such as freezer and cooler, in one connected walk-in.
Renting is not the only option. The same equipment is available to buy when the need becomes permanent. Either way, the cold storage line covers -40°F to +104°F (-40°C to +40°C), ZTRACK provides remote monitoring of temperature and alarms, and units carry a 5-year warranty.
Before renting, map three things: how many pallet positions you need today, how much picking room your team uses, and where volume will be in a year. Those answers set the starting size and how many modules you are likely to add.
What is a walk-in freezer rental?
A walk-in freezer rental gives you a frozen-storage room you can walk into, without buying or building it. ZGROUP rents refrigerated containers that work as portable walk-in freezers down to -40°F, and ZSTORE XL modular freezers of any size, like the 3XL in this project. Rentals start at 30 days, seasonal contracts run 3 to 12 months, and every model is also for sale if the need becomes permanent.
