Rental process from HZ KONTEJNERY s.r.o.
1. Inquiry and offer
For an ideal offer, we recommend providing:
- Exact location address (due to transport).
- Expected rental duration (days, weeks, months, years).
- Specific requirements: temperature range, types of goods, accessibility, need for crane/forklift.
- Whether you require transport and installation “turnkey”.
The response typically includes a price quote with detailed breakdown (rental, transport, possibly service).
2. Transport and installation
- Transport is provided by a truck with a hydraulic arm or crane (depending on accessibility).
- Requires reinforced and level surface (concrete, panels, gravel, rails), minimum handling space.
- Connection to the grid: CEE 380V/32A socket up to 12 m from the container.
- After placement, simply connect power, set temperature, and start the unit.
3. Rental type
- Short-term rental: Events, festivals, equipment failures, emergency situations; typically from 2 days, can also be for a weekend.
- Long-term rental: Essential for companies with variable demand, without worries about ownership, maintenance and service, possibility of exchange for a newer type.
Typical uses and applications
| Industry | Typical use |

Comparison: Freezer container vs. Stationary freezer box
| Feature | Freezer container (Reefer) | Stationary freezer box (Walk-in Cooler) |
|---|---|---|
| Mobility | High (transport, quick relocation, temporary installations) | Low (fixed installation, designed for permanent placement) |
| Durability | Extreme (seawater, frost, UV, impacts) | Medium (interiors, less exposed to external influences) |
| Installation | Delivered complete, requires crane/arm, grid connection | Assembly on-site from panels, simpler electrical connection |
| Accessibility | Heavy doors, designed for pallet handling | Light doors for frequent personnel movement |
| Noise level | Higher (industrial units) | Lower (minimal operational disturbance) |
| Energy efficiency | High due to quality insulation, but higher consumption with frequent handling | Efficient with smaller volume and frequent entry |
| Rental price | Standardization = often more favorable | May be higher due to custom assembly |
Conclusion: If you need a robust, quickly available and truly mobile solution with large capacity, a freezer container is the ideal choice.
Frequently asked questions (FAQ)
- What is the electrical energy consumption?
- Maintenance mode: lower consumption, full operation (initial cooling, high outdoor temperature): up to 10 kWh/hour, it is recommended to calculate with a reserve.
- What needs to be prepared before delivery?
- Reinforced surface, sufficient space for handling, preparation of electrical connection 380V/32A, ensuring access for crane/arm.
- Can a container be rented just for a weekend?
- Yes, but transport makes up a larger part of the price than with longer rentals.
- Difference between “freezer” and “chiller” container?
- It is the same type of equipment, the temperature setting decides: below 0 °C = freezer, +1 to +10 °C = chiller.
- Why is “T” type floor important?
- It ensures circulation of cold air under the cargo, prevents hot spots, improves overall cooling efficiency.
