Ensuring the correct temperature for temperature-sensitive products is crucial for cold chain security. In the transport of food, pharmaceuticals, and biological samples, a slight temperature fluctuation can compromise product integrity.
For this reason, MELFORM designs passive refrigeration systems that ensure reliability, efficiency, and energy independence.
Among the most advanced solutions: eutectic plates and cryogenic CO₂ systems, which can be integrated into CARGO isothermal containers to meet the most complex transport needs.
Eutectic plates are genuine thermal energy accumulators: they operate through the phase change (liquid/solid) of an aqueous solution which, once frozen, melts slowly, maintaining a constant temperature.
Key advantages of MELFORM plates:
- Thermal Stability: Maintain the desired temperature for long periods, ensuring the safety and quality of transported products.
- Energy Independence: Do not require electrical power.
- Optimized Freezing: Compatible with the MELFORM Rapid Cooler system, which accelerates the conditioning process.
- Food Safety: Non-toxic and safe eutectic content.
- Ease of Use: Simple to pre-condition and position inside the isothermal containers.
Available Range:
- Piastra fresco (+3°C): per alimenti e prodotti refrigerati.
- Frozen Plate (-21°C): For frozen products.
- Frozen Plate Plus (-21°C): For even longer holding times.
- Hot Plate (+70°C): For transporting hot food.
Best practice for use:
- Chilled Plate → condition at -10°C.
- Frozen/Frozen Plus Plate → condition at -30°C.
- Hot Plate → preheat in water at +80°C for 50 minutes.
For optimal performance, the use of the MELFORM Rapid Cooler is recommended, as it reduces freezing times and improves the overall efficiency of the system.
When ultra-low temperatures must be maintained or particularly sensitive loads need to be managed, MELFORM offers cryogenic solutions based on CO₂ (dry ice or carbon dioxide snow).
These systems exploit the sublimation of carbon dioxide snow at -78°C, ensuring rapid, uniform, and constant cooling over time.
The CRYO POWER BOX is an advanced cryogenic system designed to integrate the use of CO₂ into CARGO isothermal containers.
Key Features:
- Compatible with the most common semi-automatic carbon dioxide snow injection systems.
- Available in one or two-compartment versions for optimal refrigerant dosing.
- Maintains ultra-low temperatures for extended periods.
- Ideal for transporting frozen products and, with appropriate measures, also chilled products.
Benefits:
- Rapid and effective cooling.
- Uniform temperature inside the container.
- Versatile solution for various types of transport.
The CRYO POWER TRAY represents a practical and flexible solution for using dry ice in pellets, blocks, or loose bags.
Technical specifications:
- Material: Stainless steel, resistant, hygienic, and easy to clean.
- Installation: Removable, positioned on the eutectic plate guides, and secured with safety brackets.
- Compatibility: Suitable for different types of solid CO₂, based on transport needs.
- Versatility: Ideal for frozen products, but also usable for chilled goods with the right configuration.
The system allows for homogenous cold distribution, with the possibility of easily replacing or refilling the refrigerant.
Box or Tray? The practical usage guide
- CRYO POWER BOX (Box): Perfect for those needing prolonged thermal autonomy, managing CO₂ in a controlled and safe manner.
- CRYO POWER TRAY (Tray): The ideal choice for flexibility and operational practicality, especially for short transports or those requiring frequent loading/unloading.
The choice depends on the product type, transport duration, and environmental conditions. The MELFORM Technical Office is always available to advise on the optimal configuration and develop customized solutions.
For over forty years, MELFORM has been designing and manufacturing isothermal and refrigerated solutions for the transport of temperature-sensitive products. Sector experience and an engineering approach allow for the offering of tailor-made, reliable, and sustainable solutions.
