GR300 is the ideal solution for remote control, remote access, and monitoring of finned-pack heat exchangers and ventilation systems.
GR300 collects and stores data, information, and measurements, remotely controls the status and operation of systems and machinery.
Thanks to the intuitive configuration interface, programming GR300 is within everyone's reach. With GR300 it is possible to select the data to sample, set alarm, control, and activation thresholds, implement automated logics based on action/event correlation or mathematical formulas.
Through an instant messaging service, it is possible to communicate with the device, issue commands, and receive fully customizable real-time alarm messages.
GR300 is always reachable online with maximum reliability. Encrypted protocols and VPN guarantee the highest security standards in communication and data management.
GR300 features a rich library of communication drivers to simplify configuration and facilitate start-up. The main integrated manufacturers are: Dixell, Carel, Eliwell, EVCO, Pego.
When required, it sends the HACCP report of the monitored refrigeration equipment directly to the email inbox.
