Electronic fan speed controllers

Product catalog summary
Overview: The document discusses electronic fan speed controllers, specifically the AURT and ARUS models, designed to enhance energy efficiency in refrigeration systems. AURT uses the cut phase principle, while ARUS uses the transformer principle.
Functional Principles: AURT and ARUS controllers improve energy efficiency by reducing condensation levels using a PID closed-loop control mechanism. This allows users to set a minimum acceptable condensation temperature, optimizing energy consumption.
Energy Efficiency: The document highlights the advantages of PID logic over traditional proportional controllers, maintaining maximum fan speed until the minimum set temperature is reached for precise modulation and improved energy efficiency.
MODBUS Communication System: Equipped with RS 485 ports for MODBUS protocol, these controllers allow comprehensive management of settings, monitoring of fan voltage and current, and anomaly recording. The interface software facilitates operational adjustments and alarm management.
Key Parameters: Example parameters include a design condensation temperature of 45°C, a minimum acceptable condensation temperature of 24°C, an evaporation temperature of -10°C using R404A fluid, and a maximum cooling capacity of 311 kW with 5700 annual operation hours.
Conclusion: The document emphasizes the intelligence of the new controllers, featuring active control for the lowest condensation point, remote management via Modbus, and automatic emergency interventions.
Roller Selection: Available diameters for ARUS models range from Ø 500 to 1000, with special versions for SCU models.
Electronic Fan Speed Controllers: Operating on the cut phase principle with proportional logic, these controllers are suitable for low to medium capacity units, maintaining condensing pressure or fluid outlet temperature within preset values.
Technical Specifications: Includes electricity supply of 1 ~ 230 V 50 Hz, protection class IP 65 or IP 55, ambient working temperature of -20 ÷ + 50 °C, and regulation field of 0% ÷ 100% of rotation speed.
Electrical Panel: Controls fan function with features like a main switch, commutation switch, isolator switches, and protection fuses, supporting fan control management via ON-OFF switching.
Specifications and Features: The AQE series electrical panels include maintenance switches, speed controller connections, and fan terminals, designed to start fans sequentially to limit inrush currents.
Control Systems: AQEP and AQET panels modulate capacities using pressure and temperature sensors, featuring remote control capabilities and alarm systems.
Water Injection Control: Equipment for controlling water injection in condensers and coolers, operating with AURT or ARUS speed controllers.
Fans with EC Motors: EC technology fans are noted for energy efficiency and integrated control systems, modulating speed based on requirements.
Quality Assurance: LU-VE's quality system is certified to UNI EN ISO9001:2008, covering development, testing, production, and inspection procedures.
Installation: Fan speed controllers can be mounted on air-cooled condensers or dry coolers, or supplied separately.
2-Year Guarantee: Products are guaranteed against construction defects for two years, excluding corrosion damage.
Selection Software: A software for selecting controllers, REFRIGER®, is available.
Company Overview: LU-VE, a leader in heat exchange components since 1986, is known for innovative solutions and high-quality standards, with a significant global presence.
Contact Information: LU-VE has offices in multiple countries, with contact details provided.
