Envirotainer Releye® RLP container

True innovation

Setting a new standard for temperature- controlled air cargo containers, the Releye® RLP is designed to meet the strictest requirements in pharmaceutical air freight. With its unsurpassed 170 hours of autonomy (more than one week) it will maintain the temperature and protect the cargo longer than any other available solution, without recharging. In most cases, it will be regularly recharged and keep protecting the cargo indefinitely. The integrated live monitoring enables a unique insight into product condition, location and progress of the shipment and sets a new standard for secure cold chain solutions.

We listened to our customers and designed the Releye® RLP according to five integrated advances

1. Control

The Releye® RLP utilizes the latest technology and software for a consistent performance in any shipping scenario. The airflow, which is within the walls, provides a homogeneous temperature in all areas of the cargo bay. Thus, cargo will be protected independent of size, mass or position inside the container. The solution also comes with the latest vacuum insulated panel (VIP) technology that protects the cargo during the most extreme ambient conditions. Completely independent temperature control systems provide redundancy on all critical container functions.

2. Monitoring

The unmatched live monitoring of position, temperature, battery level, humidity, door openings and cargo inside, allows you to continuously track your shipment as well as the status of your cargo. Thanks to the full sensor integration of the Releye® container, you can set up a customized alert notification system based on your specific needs and requirements and get an early notification prior to arrival, which enables process improvements and delivery planning. This also leads to quicker investigations of risk assessments related to counterfeit, security concerns or shipment processes.

3. Autonomy

With unsurpassed maintenance free autonomy of 170 hours (more than a week), the Releye® RLP protects the integrity of the cargo. The 170 hours is more than any passive solution and unlike passive, it can also be recharged whenever needed. This autonomy is enough to also cover transit-time and delays, without recharging. As the Releye® RLP has an excessive margin on its autonomy, it reduces the impact of process deviation, delays or unexpected change of route.

4. Value

The RLP format, a new revolutionary footprint size, utilizes the space of two single-pallet containers on an aircraft to deliver three Euro pallets, thus achieving a 50 percent increase in efficiency. The Releye® RLP also has the highest internal loading height in the industry of 132 cm (52 in). Thanks to the advanced airflow technology, it is possible to utilize this height to the maximum. In addition, the Releye® RLP is designed and verified for efficient Global Qualification.

5. Sustainability

Envirotainer operates the most CO2 effective fleet in the entire temperature-controlled air freight industry. The introduction of the Releye® RLP reinforces this market leadership. The Releye® RLP provides outstanding environmental performance, delivering up to 90% reduction in CO2 emissions compared to available passive solutions, based on life-cycle analysis. Envirotainer’s operations are 100% climate neutral since 2020.
