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.

Adaptive 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.

01

Automatic backup

In the event of a fault with the primary machine, the system keeps the secondary machine running without any operational interruptions.

02

Control redundancy

Transfer of operational control from the primary machine to the secondary machine using configurable priority rules.

03

Critical environments

Safety features of particular relevance to healthcare facilities and controlled-contamination environments.

04

Alarm management

Configurable alarms with local and remote notification for prompt action.

05

Continuous ventilation

Prevention of interruptions in ventilation and air exchange cycles in buildings where stoppages are not acceptable.

06

Risk mitigation

Intelligent priority management helps to safeguard people, products and infrastructure.

Continuous Modulation

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.

Significantly lower energy bills
Fewer machine stoppages thanks to continuous modulation
Significantly longer service life of components
A more efficient and competitive product for the manufacturer

SIMULATION — STEPPER CONTROL OF THE EXPANSION VALVE

Stepper Motor Control

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.
