Our refrigerated containers suit your needs
Refrigerated containers — as diverse as your industry
The components are subjected to various functional and load tests in the refrigerated container, where the effect of different temperatures on the components can be tested.
Research projects and long-term studies can be carried out at any location under ideal climatic conditions.
Refrigerate food and drinks in a refrigerated container at your next major event, festival or company party.
In refrigerated containers, the supply of fresh air, humidity and composition of the air can be controlled, for example, to control ripening processes. For this reason, refrigerated containers are used particularly frequently in fish, meat and wine production, as well as by bakers and dairies.
Refrigerated containers are used as cold and interim storage in wholesale markets, pharmaceutical companies, at folk festivals or on farms in order to be able to store crops or other foodstuffs flexibly and in a space-saving manner.
We are your partner for renting, selling, maintaining and repairing refrigerated and insulated containers.
Insulated containers only require a 400 V 32 A power connection. This is why reefers are ideal not only for transport, but also as a small cold storage facility.

Selecting a location for cold rooms
1. Keep your distance
- At least 2.5 m distance to the next wall on the aggregate side
- Enough space on the sides to open the doors and for maintenance access
2. Ensure good ventilation
- outdoor installation: weatherproof but protect from direct sun
- Indoor installation: Prevent heat accumulation — enable supply and exhaust air
3. Sturdy subsoil
- Resilient up to 30 t at full load
- Recommended: concrete, asphalt or fixed steel plates
- Inappropriate: Soil, gravel or turf without substructure
4. Ensure horizontal orientation
- Prevents compressor damage
- Ensures correct condensate drain
5. Pay attention to weather extremes
- summer: Cooling capacity can drop after 40 °C — shade makes sense
- Winter: Remove snow/ice from intake openings, check the aggregate

Dimensions & capacity
temperature ranges Are at around -30 °C to +30 °C, depending on the unit and model. In this way, both frozen products (e.g. -18 °C) and chilled goods (e.g. +4 °C) can be kept reliably.
Reefer containers are of internationally established sizes 20 feet and 40 foot/40 foot high cube available. The external dimensions fully comply with ISO shipping container standards — a decisive advantage for companies that move containers by truck, rail or ship.
Refrigerated container gallery
The aluminum T-floor
Refrigerated containers usually have a so-called T-floor made of T-shaped aluminum profiles, which are laid lengthwise.
There are slits between the T-profiles, which are a uniform air circulation under the load. The cold air is fed from the unit down into the T-floor blown, flows backwards and upwards and is sucked in again at the top — this evenly cools the entire interior.
Important: Cargo may only go up to the marked Stauhöhe Be loaded (approx. 10-15 cm below the ceiling) so that the air can circulate at the top and is not blocked.
Frame & outer structure
The design is specifically designed for a long service life and constant cooling capacity.
- Made from weather-resistant Corten steel
- Suitable for outdoor installation and transportation under full load
- ISO compliant, stackable, suitable for cranes and forklifts
interior
Our refrigerated containers meet all relevant EU requirements for hygiene and food safety and are complete HACCP compliant. The smooth stainless steel surfaces prevent the accumulation of germs, support safe operation in accordance with food standards and can be cleaned quickly and thoroughly.
- Lining made of stainless steel or aluminum
- Hygienic, rust-resistant, easy to clean
- Ideal for food, pharmaceutical, and manufacturing environments
isolation
- PU foam 100-120 mm, depending on the model
- Optimized for energy efficiency and low heat losses
- Relevant cost factor in continuous operation
This design enables energy-efficient cooling even at high outdoor temperatures or intensive use.
door mechanism
Door mechanism: Refrigerated containers have double-wing insulated steel container doors with rubber seals on the front (rear), similar to standard sea containers. The door wings are secured with vertical locking rods and levers. When closed, they seal hermetically to prevent loss of cold.
Modern refrigerated container doors usually have a Emergency release from the inside, so that trapped people can free themselves — an important safety feature. In addition, a pressure relief valve is often installed to compensate for a vacuum when cooling and to make it easier to open the door. For frequent loading and unloading, a strip curtain be installed behind the door from plastic slats. This minimizes cold loss when the door is open (the cold air stays better in the container).
Power connection and electrical requirements of a frozen container
An actively cooling container requires a suitable power supply.
Standard-Kühlcontainer werden mit Drehstrom 380–460 V, 50/60 Hz und 32 A betrieben.
Construction and insulation technology
Active coolers
An actively cooling container requires a suitable power supply.
400 V/50 Hz are common in Europe, for example 440 V/60 Hz on ships — most units automatically support both frequencies.
Power is supplied via a 5-pin CEE industrial plug (32A, red) for sea use and 4-pin for land use. The container is usually delivered with a suitable plug and connection cable (usually 10-15 m), which is connected to an appropriate CEE socket. On land should an electrician provide a dedicated three-phase circuit, protected with 32 A inputs (or C/K characteristic, due to starting current). An FI circuit breaker (RCD) is also recommended, as the container is often outdoors.
Energy-efficient reefer technology for economical and safe operation
Moderne Reefer-Aggregate können gegenüber älteren Modellen spürbar weniger Energie verbrauchen. Wie hoch die Einsparung ausfällt, hängt jedoch vom Baujahr, Zustand und Einsatz ab.
Auch das Kältemittel beeinflusst die langfristigen Betriebskosten. Vor allem R404A steht wegen seines hohen Treibhauspotenzials unter zunehmendem regulatorischem Druck. R452A wird häufig als Alternative zu R404A eingesetzt, ist aufgrund seines weiterhin vergleichsweise hohen GWP-Werts jedoch eher eine Übergangslösung. R513A weist ein deutlich niedrigeres GWP auf und kann – sofern vom Hersteller freigegeben – eine zukunftssicherere Option darstellen.
Für Betreiber bedeutet das: geringere Energiekosten, besser kalkulierbare Wartungsaufwendungen und weniger regulatorische Risiken.
Der tatsächliche Stromverbrauch hängt insbesondere von Außentemperatur, Sollwert, Beladung, Aggregatzustand und Anzahl der Türöffnungen ab. Ein 20-Fuß-Kühlcontainer kann bei einer Innentemperatur von +2 °C unter moderaten Bedingungen ungefähr 15 bis 30 kWh pro Tag verbrauchen. Dieser Wert dient nur als Orientierung; für eine belastbare Kalkulation sind die technischen Daten und der Zustand des jeweiligen Aggregats entscheidend.
Optionally also as an insulated container without an active cooling unit
All our refrigerated container models can also be purchased as insulated containers without an active unit. This means that you can use the same first-class insulation to protect your goods from changes in temperature. Refrigerated containers are specially designed to actively control temperatures and can both cool and heat. They are ideal for storing sensitive goods that require specific temperature ranges. Insulated containers, on the other hand, are mainly used to keep the temperature within a stable range without actively cooling or heating. They provide effective insulation to minimize the ambient temperature from outside and are good for storing goods that need to be protected from extreme temperatures.

Cooling with system
Cooling systems offer reliable cooling, flexible applications and maximum energy efficiency. Choose between classic cooling systems, powerful superfreezers for low temperatures down to -60 °C or efficient insulated containers for passive protection.
Cooling, freezing, storage — our systems at a glance
- Cooling container (“Reefer”): Standard temperature from -25 °C to +25 °C, with integrated unit and insulated walls.
- Tiefkühlcontainer bezeichnet einen Kühlcontainer, der dauerhaft im Tiefkühlbereich betrieben wird – typischerweise bei −18 °C oder darunter. Oft handelt es sich technisch um denselben Reefer, nur mit einem anderen Sollwert.
- Superfreezer: Suitable for frozen chains down to -60 °C. Ideal for pharmaceuticals, research, high-quality meat.
- insulated container: Passive insulation without aggregate. Protection against heat and cold for sensitive goods.
Benefits of our containers:
- Plug & Play connection (400 V/CEE 32 A/5-pin)
- Hygienic inner lining, stainless steel floor with groove profile for air circulation
- Regularly testable refrigeration units (certifiable every 3 months)
- Flexible installation both indoors and outdoors, with a wall distance of at least 50 cm
- Optional ramp, heavy-duty shelves and temperature monitoring via app
Can a refrigerated container also heat/heat?
Yes Refrigerated containers are able to fill the interior via to maintain the ambient temperature, as they are equipped with heating rods or heat pump functions. For example, a reefer can easily keep +5 °C inside in winter at -10 °C outside temperature. Most can be adjusted to an internal temperature of around +30 °C. They are not designed for higher temperatures (then it would be a heat chamber container). In practice, the heating function is used to protect goods from frost or to keep products stored in cold stores below their target value.
