Proper humidification is crucial for personal comfort and well-being in our modern society. It reduces dust, improves indoor air quality, and saves on heating costs by making spaces feel warmer. Air handling units are modular and perform various functions, such as air mixing, filtering, heating, cooling, humidifying, and dehumidifying.

During dry winter months, humidification reduces dust and enhances indoor air quality by preventing fiber fragmentation. In office buildings, integrated systems optimize costs and productivity. Moreover, stable humidity is vital for preserving valuable art and objects, preventing damage to paintings, wood, and parchment due to fluctuations in humidity.

CAREL offers innovative solutions for hot display cases, retarders, and blast chillers with user terminals. These solutions ensure proper food storage and HACCP-compliant temperature control. Users can set parameters directly, including time and temperature limits, with continuous monitoring of units. The system also includes an air humidity controller and optimizes strategies for blast chillers. It guarantees temperature control compliance and can be programmed on the instrument or through a supervisor system if available.

Food storage in the food industry employs different methods depending on the duration required. Short-term storage, typically up to 7°C, involves refrigeration, which effectively slows bacterial growth and preserves food's organoleptic properties. Refrigeration systems, whether industrial or consumer-oriented, rely on standard techniques, with chillers playing a vital role in heat exchange for optimal food preservation. Cold rooms are pivotal in the cold chain, with proper management crucial for preserving product quality and energy efficiency. They can be categorized by temperature (normal or low) and system type (stand-alone, remote condenser, or centralised), depending on the stored goods. Various electronic controllers, including probes, compressors, fans, and alarms, are used to manage these cold rooms, and companies like CAREL offer advanced control panels for flexibility and ease of use in this regard.

The compressor rack is a crucial component in refrigeration systems, responsible for distributing cooling. CAREL's retail sistema caters to manufacturers, offering a range from simple hermetic compressors to large racks with energy efficiency as a key focus. Electronic expansion valves and advanced controllers maximize energy balance. Two platforms, μRack and pRack, are offered. μRack is suitable for small systems, featuring compact controllers with high-efficiency displays, flexible mounting, clear indicators, and advanced features. pRack is designed for complex centralized systems, offering extensive inputs and outputs, energy-saving algorithms, multilingual software, hardware compatibility, network connectivity, reduced electrical connection costs for remote fans, and optimized compressor efficiency.

Chillers are essential for refrigeration systems, ensuring proper temperature control and monitoring. The CAREL retail system emphasizes energy efficiency and reliability. It utilizes solutions for high-performance operation, reduced energy consumption, and backup procedures for safety. Refrigeration in the food industry is complex but critical for preserving food quality and extending storage time. The use of E2V electronic expansion valves in chillers optimizes energy savings by enabling flexible pressure control, achieved through real-time strategies in the CAREL retail system.

Retrofitting existing refrigeration and air conditioning systems worldwide is a significant endeavor due to the sheer number of installations. This process, driven by environmental directives and business opportunities, involves implementing detailed monitoring to meet HACCP regulations. Benefits of such retrofits include precise temperature control, reduced wiring through wireless technology, simplified data recording, event detection with automatic notifications, streamlined reporting, remote system monitoring, and the convenience of a single supplier like CAREL, which offers a plug-and-play solution for easy field replacement of electrical panels with valve drivers and electronic valves. This solution requires no special settings, making it installer-friendly and compatible with existing control parameters.

Heat exchangers are critical for efficient chiller cycles in various applications, requiring precise electronic control. CAREL offers programmable controllers (pCO) that manage these systems, reducing space, simplifying wiring, and enabling real-time monitoring.

They also provide inverters to meet diverse customer needs, offering comprehensive, high-value solutions that promote standardization and cost reduction. CAREL tailors solutions for different heat exchanger types based on factors like space, load, and motor type.
br>Certified by leading ventilation industry names, their pCO controllers optimize fan performance and simplify wiring through Modbus serial communication, resulting in more compact control panels without the need for electromechanical components like electromagnetic switches.
