Ultra Low temperature Container - ULT 25 - Ideal for low temperature logistics in demanding environments and requirements!
Turnkey, customised low-temperature containers with air (R729) as refrigerant for flexible use from -30°C to -110 °C - Planned and realised to meet your requirements.
Our ULT containers are designed to meet customer requirements and given space with storage systems, safety, loading and unloading concepts. They consist of special industrial panels with PU foam filling, with optional integrated vacuum panels, which are mechanically stable enough for extreme temperatures and achieve a sufficient insulating effect. For the low-temperature rooms, we use the flexible cold air chillers from Mirai Intex, which can realise temperatures from -30 °C to -110 °C (optionally up to -160 °C). Appropriate airlock systems are integrated for energy optimisation and ice fog reduction.</p
The machine control system is implemented with an S7 and our developed safety concepts and can be expanded to meet customer requirements, such as GMP Audit Trail with GAMP5. The equipment in the storage rooms is integrated, from temperature monitoring and LED lighting to shelving and rail systems.
The insulation is realised with tried-and-tested polyurethane insulating elements. These can be optimised with integrated vacuum panels depending on requirements. When cold, the inner elements contract and the outer shell remains warm. This results in mechanical stress, which increases the greater the temperature difference and the larger the chamber. Our chambers are reinforced with hook locks so that the chambers remain mechanically stable even after many temperature changes. We also check all our installations with a thermal imaging camera to optimise penetrations, such as for cable penetrations.
The engine room is located at the rear of the container. It houses the cold air machine from Mirai Intex, the -20 °C CO₂ refrigeration machine for cooling the airlock, control cabinets for controlling and regulating the container and its components.
The solution includes the complete control system, including control cabinet. The control system is realised via an S7 from Siemens and can optionally be equipped with a redundant, high-availability control system, additional backup control system and audit trail (GAMP 5). The control system can be integrated into the building management system (BMS) using the classic interfaces. In addition, faults can be detected and rectified at an early stage via remote maintenance if required.
The lighting is realised with robust special LEDs. Unlike normal LED lights, these remain bright at low temperatures and can be switched on and off. This enables very efficient and safe operation. They are also battery-buffered so that the room can be left safely even in the event of a power failure.
Reliable, durable, efficient and safe for people and the environment!
The containers are robust, equipped with a non-slip floor, redundant and battery-buffered LED lighting. The actively cooled airlock minimises the formation of ice mist and ice deposits in the container. The airlock is also monitored with CO₂ sensors for safe dry ice handling. Our dead man's switch has proved particularly effective. Door opening is recognised via the door contacts. A timer then starts, which must be acknowledged on exiting. Otherwise, the flashing light and the horn start. After a further 30 seconds, the plant security can optionally be informed.
The container only requires a power connection of 400V/63A and a cold water connection of +4 °C VL with 30 kW, which can also be supplied as an option. Otherwise, the container is weatherproof and suitable for extreme conditions.
We carry out a detailed cooling load calculation with your requirements and then use the appropriate, efficient refrigeration technology with exclusively natural refrigerants. For low temperatures below -40°C, the cold air cooling technology from Mirai Intex with only air (R729) is used in the open version. With its mechanical defrosting, this ensures homogeneous temperature distribution, dry storage air with a dew point reduction of up to +20°C and constant temperatures without defrosting cycles. For airlock cooling and cold water generation, we use CO₂ (R744) or propane (R290) for cooling as required. These natural refrigerants are free from political regulations such as the F-Gas Regulation.
Air as a refrigerant is free of charge, free of regulations and safe. The systems are robust and specially designed for low temperatures.
Proven technology - Made in Germany. Low-wear and redundant.
Customised design with freely selectable temperatures during operation.
Speed-controlled, no vaporiser, expander with energy feedback to the turbo unit, low spec. surface, vacuum insulation and airlock.
Natural refrigerant with no high pressures, no toxicity and no flammability. 0 GWP, 0 ODP, 0 TFA. High level of personal protection thanks to dead man's switch, escape routes, low ice mist and non-slip floors.
No leak test, air-bearing compressor = no wear, no oil. High-quality insulation.
Refolution supported me in the technical verification of design and dimensioning of a Natural Refrigerant Cooling System for a new Freeze Dryer system.
I was very happy with the immediate support and competence of the Refolution Team. Thanks for your help.
With Refolution, the future of sustainability succeeds, coupled with efficiency and foresight.
The professional for the future.
The ULT container is a standard system, including storage system, safety, loading and
relief concept. The container consists of special insulating panels with PU foam, which are mechanically
stable enough for extreme temperatures and provide sufficient insulation for the
low temperature range.
For the main storage room, we use the flexible cold air chillers from Mirai Intex, which
realise temperatures from -40 °C to -110 °C (optionally up to -160 °C).
For energy optimisation and ice fog reduction, a corresponding airlock system
is integrated, which also ensures access to the main storage room.
The main task of the passively cooled airlock is to guarantee a limitation of the exchanged
air volume between the ambient air and the main storage room.
