The Eliwell Free and Free Studio platforms
All of our solutions are based on Eliwell's FREE series, a family of programmable controllers designed specifically for refrigeration, HVAC, and industrial processes:
- FREE Evolution: The high-end programmable controller, with an integrated or remote display, expandable via expansion modules, and designed for complex multi-circuit installations.
- FREE Way and FREE Advance: compact and powerful solutions for applications that require programming flexibility in small form factors.
Programming is done using FREE Studio, Eliwell’s development environment based on the languages defined in the IEC 61131-3 standard—the same standard used by industrial PLCs. This means your application isn’t a black box: it’s a documented, maintainable, and expandable solution for the future.
In terms of connectivity, FREE controllers communicate via Modbus RTU/TCP and integrate with monitoring systems and BMS, remote management platforms such as TelevisGo, and web-based remote access solutions.
Your system, monitored from the office or on your cell phone.
A programmable controller is the natural evolution of traditional parametric control: while a conventional thermostat or controller operates with factory-set functions, a programmable controller allows you to develop the exact control logic your system needs. Management of multiple circuits, custom sequences, integration of any type of sensor, communication with other equipment, and remote monitoring—all in a single device.
At Eliwell Ibérica, we develop custom applications based on the Eliwell FREE product line for three major areas: industrial and commercial refrigeration (freezing tunnels, blast chillers, dryers, ripening and fermentation chambers), air conditioning and HVAC (chillers, air handling units, fan coils), and smart building control (web-accessible data loggers, pump management, commercial building automation, and BMS integration).
The result: facilities that consume less energy, where our customers reduce their energy consumption, operate more reliably, and can be monitored from anywhere.
WHAT PROGRAMMING DO YOU NEED ?
HVAC SOLUTIONS
REFRIGERATION
HVAC SOLUTIONS
Universal Control Chillers
Advanced control for single- and dual-circuit chillers: compressor, condenser, and safety management. Lower energy consumption and a longer service life for your equipment.
Universal Control for AHUs
Intelligent management of air handling units: temperature, humidity, free cooling, and heat recovery with minimal energy consumption.
Centralized control of fan coils
Manage all fan coils in hotels, offices, and buildings from a single interface: zones, schedules, and centralized monitoring.
Eliwell Ibérica offers you intelligent and easy-to-implement control solutions designed to optimize your processes, reduce costs and ensure maximum efficiency.
ADVANCED REFRIGERATION SYSTEMS
Control for tunnels and chiller
Ultra-rapid freezing and rapid cooling using needle-probe cycles, with data logging and traceability. Better preservation, lower cost per cycle.
Humidity Control and Dryers
Precise temperature and humidity control for sausage, ham, and cheese drying rooms, with phased profiles and process logging.
BREAD FERMENTATION CONTROL
Controlled-fermentation chambers: programmable cooling, tempering, and fermentation cycles so you can bake whenever you choose.
FRUIT RIPENING
Ripening chambers for bananas, avocados, and mangoes: temperature, humidity, and gases at each stage, for the exact point of market readiness.
INTELLIGENT CONTROL
Datalogger with web
Advanced web-based data logging and monitoring system: view real-time temperatures, humidity levels, alarms, and the status of your facility from any device, with an exportable history for audits and HACCP.
Home Automation Control for Commercial Spaces
Comprehensive automation for retail locations and franchises: centrally managed climate control, lighting, signage, and operating hours. Reduces the location's energy consumption and ensures consistent conditions across all points of sale.
PUMP MANAGEMENT
Precise control for pump groups and hydraulic systems: pump alternation and cascading, constant pressure with variable-speed drives, protection features, and fault alerts. Efficient water management and extended equipment lifespan
BMS INTEGRATION
Connect all your facilities into a single building management system (BMS): FREE controllers integrate via Modbus with leading monitoring platforms, creating an efficient and easy-to-manage technological ecosystem.
HOW WE WORK
1
Installation Analysis
We work with you to analyze the process to be monitored: equipment, sensors, sequences, applicable regulations, and savings targets. This leads to a comprehensive technical and financial proposal.
2
Development and Simulation
Our team programs the application in FREE Studio and tests it on a test bench before installing it at your facility. No surprises during commissioning.
3
Start-up
We assist with installation and startup, adjust parameters while the actual process is running, and train your staff on how to operate the system.
4
Ongoing support
The application is documented and supported by our Technical Support Team (SAT). If your process changes, the programming evolves with you: expanding a programmable device means modifying the software, not replacing the hardware.
FREQUENTLY ASKED QUESTIONS ABOUT PROGRAMMABLE CONTROLLERS
What is the difference between a parametric controller and a programmable controller?
A parametric controller comes with factory-set functions and only allows you to adjust parameters (setpoints, differentials, delays). A programmable controller allows you to develop a complete, custom control logic: the number of inputs and outputs, sequences, communications, and displays are designed specifically for your installation. When the process does not fit a standard control system, a programmable controller is the solution.
Is a programmable controller the same thing as a PLC?
Functionally, they are equivalent: the Eliwell FREE series is programmed using the languages defined in the IEC 61131-3 standard, just like an industrial PLC. The difference is that the FREE series is specifically designed for refrigeration and HVAC, featuring inputs for NTC/PTC/Pt1000 sensors, relay outputs sized for compressors, and pre-tested refrigeration function libraries. You get the flexibility of a PLC combined with refrigeration-specific expertise.
Can it be integrated with my monitoring system or BMS?
Yes. FREE controllers communicate via Modbus RTU and Modbus TCP, which allows them to be integrated with virtually all BMS and SCADA platforms on the market, as well as Eliwell's remote management systems, such as TelevisGo.
How long does it take to develop a custom app?
It depends on the complexity, but most projects are delivered within a few weeks of the technical proposal’s approval. With more than 500 programming projects completed, many applications are based on proven solutions that we adapt to your facility, which shortens timelines and reduces risks.
Can I really reduce my energy consumption with a programmable thermostat?
Yes, and it’s one of the main reasons our customers take the plunge. Strategies such as floating condensation control, optimized defrost management, compressor rotation, and free cooling in HVAC systems can yield savings of up to 30% compared to conventional controls, with payback periods typically under two years.
What happens if my process changes in the future?
That is the great advantage of programmable control: the application is software. If you expand the installation, change the process, or regulations require new records, we can modify the programming without replacing the equipment. All of our documentation is archived, so any future updates build on a known foundation.
