is a mobile forced-air cooling solution designed to quickly reduce the field heat of delicate fruits and vegetables — especially berries, grapes, citrus, and avocados — within hours of harvest. Built inside modular container frames and powered by high-performance Thermo King Magnum Plus reefer units, this solution brings packhouse-grade pre-cooling directly to your farm, dock, or warehouse — no civil works, no permits, no delays.
Whether you’re a grower, packer, or wholesaler, our system protects your product’s shelf life and market value from day one.
Install at the farm or at the dock — no construction needed.
Even, high-speed temperature reduction for sensitive produce.
10–20 pallet per cycle options (2x40ft or 3x40ft modules).
Achieve optimal pulp temperature in under 2 hours.
Seasonal rental available — a true market differentiator.
Place on concrete beams or chassis for dock-level access.
Remote access, touchscreen controls, and precision tracking.
Built with enhanced Thermo King marine units (5-year warranty).
Most cooling methods (hydro, vacuum) require large CapEx, civil infrastructure, or aren’t mobile. ZGROUP’s Pre-Cooling Unit is different.
It delivers the same performance — without the limitations:
Forced-Air Pre-Cooling Tunnel.
Modular, built into 2x or 3x 40ft containers.
Under 2 hours for berries (varies by crop & packaging)
Thermo King Magnum Plus, marine-grade with enhancements
3-phase, 440–480V
Ztrack Telematics Solution
~60 days if not in stock
~2 days on-site

After a fire destroyed a cooling facility, ZGROUP deployed a modular pre-cooling system directly in the field in under a week. The system cooled and stored product while integrating a loading ramp and inflatable dock — preventing major crop loss.

During peak season, a grower installed our forced-air cooler on their dock to manage berry throughput. Post-harvest, the same unit is used for vegetable cooling — maximizing equipment ROI.
Rapid field cooling, seasonal rentals, no construction required.
Pre-shipment chilling and cold chain compliance.
Fast batch cooling for high-volume production.
Cooling bottleneck relief and capacity overflo.
Our pre-cooling blast chiller can handle a wide variety of crops — from berries, grapes, and leafy greens to asparagus and citrus. We tailor airflow to your product type for optimal results.
Yes. The unit is fully modular and can be set up in just 1–2 days. Once connected to power, it’s ready to operate with no special construction or assembly required.
Our system is installed inside an ISO container, which in most cases is considered a temporary structure. When placed on farms or installed at dock height using a chassis, most customers do not require a permit. We recommend checking with your local municipality for confirmation.
Depending on the commodity and weight, most batches (e.g., 10 pallets of berries) can be cooled in under 2 hours.
Our pre-cooling units operate on 3-phase 440–480V power. We’ll confirm compatibility during planning.
