FG800
THE PEAK OF CONTROL
The advanced control platform for commercial and industrial refrigeration systems. Absolute precision, open architecture, integrated intelligence.
The advanced control
of refrigeration
The FG 800 is the electronic controller developed by Frigotel for controlling refrigeration and air-handling systems in commercial and industrial settings.
It is a control platform designed to manage the entire machine system in an integrated manner, coordinating each component using precise logic that can be configured according to the application — ensuring operational continuity even where the slightest temperature variation could compromise quality, food safety or costs.
A single platform
for complex applications
Same architecture, sector-specific logic. The FG 800 adapts to a wide variety of system configurations whilst maintaining the same user experience.
Hardware achitecture
and integration capabilities
The FG 800 features a comprehensive I/O architecture, designed to ensure reading accuracy and long-term reliability — with a built-in real-time clock for precise time management.
Smart management
of cycles and recipes
Cycle management is not rigid: parameters, timings and intervention thresholds can be configured. Operating recipes store and retrieve complete configurations for each process.
Consistency of results
Consistent quality standards thanks to precise and repeatable processes.
Process repeatability
Eliminating manual errors with step-by-step recipes.
Dynamic adaptation
The FG 800 adapts its operation to environmental conditions in real time.
Operational continuity
and redundant management
In the industrial sector, safety means service continuity. The FG 800 incorporates advanced logic to manage critical scenarios and emergency conditions.
Automatic backup
In the event of a fault with the primary machine, the system keeps the secondary machine running without any operational interruptions.
Control redundancy
Transfer of operational control from the primary machine to the secondary machine using configurable priority rules.
Critical environments
Safety features of particular relevance to healthcare facilities and controlled-contamination environments.
Alarm management
Configurable alarms with local and remote notification for prompt action.
Continuous ventilation
Prevention of interruptions in ventilation and air exchange cycles in buildings where stoppages are not acceptable.
Risk mitigation
Intelligent priority management helps to safeguard people, products and infrastructure.
Inverter and modular
ventilation
In traditional systems, the compressor either runs at full power or stops. Through inverter control, the FG800 continuously modulates its output according to the actual heating demand.
The FG800 controls inverters and variable-speed fans via its two built-in 0–10V analogue outputs — without the need for additional modules. These same outputs allow for the proportional control of heating elements for humidity control.
SIMULATION — REAL-TIME INVERTER POWER MODULATION
SIMULATION — STEPPER CONTROL OF THE EXPANSION VALVE
Electronic
expansion valve
The FG800 features a dedicated output for direct control of the expansion valve via a stepper motor — without the need for an external driver. The precision of the valve opening directly affects the stability, efficiency and safety of the entire cycle.
Overheating
Precise control for maximum efficiency of the refrigeration cycle
Compressor protection
Active prevention against the return of harmful liquid
Cycle stability
Aperture adjusted in real time according to operating conditions
Energy efficiency
Continuous optimisation of the expander’s operating point
Remote energy saving
and measurement of power
Energy efficiency is now a competitive advantage as well as an environmental responsibility. The FG 800 allows you to adjust operating strategies remotely, using energy data measured in real time.
ENERGY CONSUMPTION MONITORING — LIVE SIMULATION
Touch screen interface:
clear and immediate control
The FG800 interfaces with 7″ and 10″ touch screens. It is not just a display panel: it is an operational tool that brings together everything needed to operate the machine on a single screen. The home page adapts to the configured application.
Real-time data
Real-time updated parameters for inputs, outputs, temperatures, pressures, consumption, evaporation and condensation. Schematic graphical view and filterable historical graphs.
Alarm management
List of active alarms showing the unit, type of fault and time. History available for up to the previous 2 days.
Multi-level access
Two-level authentication — operator and technician — to determine who can view and who can edit the machine’s settings.
One touch, more machines
Seamless switching between machines, with a dedicated home page for each application. Integrated recipe book for maturing and blast chilling.
Connectivity and supervision:
the Frigotel ecosystem
A modern system must be connected. The FG 800 incorporates RS485, UART, Wi-Fi and Ethernet communication modules for integration into local networks and remote monitoring systems.
RS485 / Modbus
TCP slave and RS485 master/slave for integration with SCADA systems and local monitoring.
Ethernet / Wi-Fi
Direct connection to the corporate network for remote monitoring and access to the portal.
UART / Converter
Modbus TCP converter for RS485 slaves, offering maximum integration flexibility.
Frigotel Web Portal
Access to documentation, warranties and support requests from any device.
Mobile App
Real-time monitoring, push notifications for alerts and parameter management via iOS and Android.
PC Monitoring
Specialised software for installation engineers, providing access to up-to-date technical documentation.
