We are leaders in
complete truck loading systems in LNG plants

At Montrel, we have established ourselves as a leader in EPC projects for cryogenic truck loading in LNG plants and their management and control systems. We currently have 100% of the market in Spain (our management and control system is implemented in all plants in Spain), Peru, Chile and Puerto Rico. In addition to cryogenic loading facilities, we also work with LNG transfer systems to small capacity ships or barges for Enagás in Barcelona and Cartagena.

In bunkering and cryogenic loading facilities, we are able to offer the management and control system of loading/unloading, supply, electricity and instrumentation, installation and implementation of skids. We are pioneers in this type of loading system for such sophisticated products as LNG. These processes involve working with liquid at -162 degrees below zero, a temperature that is difficult to handle and requires very advanced treatment processes.

Loading management and control systems
in LNG plants a unique solution in the sector


After many years of experience in the sector, at Montrel we have developed a system that provides a complete and comprehensive solution to the various needs of loading and unloading LNG trucks on a weighing platform. Based on these global premises, our solution for loading systems in LNG plants can be adapted to the particular requirements and specific needs of each client, thus creating the most customized option adapted to each project and complying with ATEX regulations.

Telematic import of orders

Access control, at both the entry and exit, with microwave identification of vehicles and people.

Compliance check with all requirements and permits necessary for transport.

Automatic control of the load, supervising the safety levels required for the process.

Preparation of all necessary documentation for transport according to ADR.

Telematic export of the real data of each load, to be used in invoicing and/or ERP.

Specifications and components of our
LNG truck loading system

Our solution for truck loading systems is made up of different equipment that is integrated through various types of communication links: Ethernet, Profibus, RS 232 lines, RS 485 lines, with or without Modbus protocol and current loop lines (for special equipment).

Our innovative system for LNG loading facilities and its complete management consists of the following:

  • Card identification terminals.
  • Microwave module identification terminals.
  • Vehicle identification system using license plate recognition.
  • Weighing platforms and terminals where loading is carried out.
  • Operator field terminals.
  • ID card recorders.

Maximum safety in
LNG loading

At Montrel we work to meet any project needs related to LNG transportation and loading in trucks. Therefore, we have increased the safety and availability levels of the system we have developed, through a redundant CPU configuration with automatic hot switching and meeting safety requirements. The system is equipped with the Siemens Safety Matrix tool (SIMATIC Safety Matrix) for the implementation of the safety loops (SIL). It also has operator workstations and redundant data servers.
