In cold-chain logistics for medical supplies, fresh food and high-end catering, keeping products at a stable temperature in transit remains a core operational problem. The Bhl504 insulated transfer box is designed for frequent, high-standard delivery routes, pairing thermal performance with a structure intended to reduce handling strain and protect cargo.
Core technology and thermal performance
The Bhl504’s thermal design centers on polyurethane foam, a core insulating material widely used in cold-chain equipment because of its low thermal conductivity. The material is intended to limit heat exchange with the outside environment and help hold the internal compartment steady. According to test data cited for the product, it can provide up to four hours of safe temperature control in ambient conditions, a window meant to protect quality and freshness during transfers.
Specifications and design details
The Bhl504, also designated FB90A, is listed with external dimensions of 63.5 by 46 by 64 centimeters, a 90-liter internal capacity and a unit weight of 13.5 kilograms. The product is certified to ISO and CE standards, according to the manufacturer’s specifications.

Beyond thermal performance, the series has been adapted for ergonomics and durability. A nylon handle is fitted to improve carrying comfort and is designed for tensile strength, while a four-wheel base is intended to reduce physical strain on delivery staff during long-distance movement. The blue exterior aids identification and is also intended to simplify routine cleaning and disinfection, a consideration for food-service and medical logistics hygiene standards.
Applications and operational value
The box is intended for a range of temperature-sensitive operations, including internal hospital sample transport, bulk catering delivery and short-haul cold-chain logistics for fresh food. Its 90-liter capacity is designed for high-density loading, while the rigid structure is meant to withstand the shocks and vibration of transport and help keep contents secure.
For operators, durable equipment of this kind can lower replacement and loss rates, and more consistent delivery conditions may improve service reliability and end-customer satisfaction. The unit’s combination of thermal control, wheeled handling and cleanable surfaces is intended for repeated use on scheduled distribution routes rather than one-off transport.
Frequently Asked Questions
Under what conditions does the Bhl504’s four-hour temperature control apply?
The four-hour figure is a reference value based on standard laboratory test conditions. In practice, performance varies with ambient temperature, the initial temperature of the cargo, how often the box is opened and how densely it is loaded. In extreme weather, operators may need to use appropriate cold packs to extend holding time.
What maintenance precautions apply to the Bhl504?
Because the box uses a PU foam insulating layer and a durable shell, routine care should avoid strongly acidic, alkaline or corrosive cleaning agents. A neutral detergent and a soft cloth are recommended, and the interior should be thoroughly dried before storage to prevent odors or mold.
Does the Bhl504 meet requirements for medical materials transport?
The product has ISO and CE certification, which provides a baseline for quality and safety compliance. For specific medical cargo such as vaccines or blood samples, operators should follow applicable medical regulations and carry out temperature validation testing to confirm that the unit meets the relevant cold-chain standards.
