Modular Cold Storage Solutions (ZSTORE)

Scalable, Flexible Cold Rooms Built with Reefer Containers

When a standard refrigerated container isn’t enough, ZGROUP’s Modular Cold Storage system – known as ZSTORE XL– is your next step forward. Designed using high-performance 20ft or 40ft reefer containers, ZSTORE XL is the perfect alternative to building or renting a walk-in cold room or large-scale freezer facility.
1Whether you’re scaling your food distribution in Texas, fulfilling orders in Hawaii, or adding capacity to your back dock in California, ZSTORE XL gives you the power to build your own cold chain infrastructure – fast, flexible, and future-proof.

The Problem We Solved

Before ZSTORE XL, businesses needing large-scale cold storage had to choose between:

ZSTORE XL combines the best of all four.

It gives you the cold capacity of a fixed facility, the control of in-house storage, and the mobility and speed of reefer containers – without the capital cost or construction complexity.

Real Projects Using ZSTORE

Los Angeles Wholesale Produce Market – Cross Dock Operation (9XL)

To boost throughput and cut logistics delays, our customer transformed their back dock into a high-efficiency cross-docking zone for fresh produce.
Using 9 connected containers (ZSTORE 9XL), they now store, pick, and dispatch orders directly from the market, cutting third-party costs and improving delivery speed.

“It was installed in weeks — not months. And we didn’t need to touch the building.”
— Director of Ops, LA Produce Distributor

Orange County – Local Avocado Grower (3XL)

A rapidly growing avocado operation needed additional cold storage in their repacking and fulfillment facility, but didn’t want to lease warehouse space miles away.
We deployed a 3XL ZSTORE unit behind their packing shed, giving them on-site control, reduced transport time, and better quality management for local delivery.

Austin, TX – Meal Prep Fulfillment (8XL)

One of the country’s fastest-growing meal kit companies faced a bottleneck at their fulfillment center.
We built an 8XL modular cold room, dividing the space into cold storage, picking, and dispatch zones, with smart lighting, temperature zones, and racking. The result: streamlined operations and same-day fulfillment for thousands of orders.

ZGROUP has provided an exceptional level of versatility to our fast-growing operations. We have been able to leverage a variety of tailor-made solutions to fit our evolving needs while minimizing capital expenditures for our business. ZGroup has delivered custom configurations and end-to-end solutions almost 3-4X faster than we were able to do before, meeting our demands for a variety of applications like fulfillment and product chilling.
