- Transmission of valuable data such as current values, duty cycles, etc. to the controller (PLC) via Modbus RS485 or another fieldbus interface
Discover the versatility of our drives, which have been specially developed for refrigeration systems. With an impressive temperature range of -30° to +60° Celsius, our frequency drives offer maximum flexibility and reliability, regardless of the conditions. This makes them the most robust option for your refrigeration system and ensures low susceptibility to faults, even under extreme conditions.
Discover the versatility of our frequency drives! With a power output ranging from 0.25 kW to 110 kW, they can be tailored to your specific requirements and are available in both IP20 and decentralized IP55/66 versions. Take advantage of the opportunity to optimize your refrigeration technology with a drive for refrigeration systems and benefit from efficiency and reliability.
Experience the revolutionary efficiency of our drives with an impressive 40 % space saving compared to conventional models! You benefit from a compact design that frees up valuable space for other important installations. Optimize your systems and increase performance without compromising on quality.
Lenze drives have a high overload capacity of 150 % for 60 seconds or 200 % for 3 seconds. This allows high overload torques to be safely achieved for refrigeration compressors, e.g. during the start-up phase. As a result, Lenze allows you to choose a drive with a lower motor power, e.g., an 11 kW frequency drive instead of a 15 kW frequency drive. This saves money and installation space.
Circulation and auxiliary pumps
Frequency drive control is recommended for precise process control such as temperature provision (e.g., in battery temperature control) or for high system efficiency COP (coefficient of performance). In addition to the i550 cabinet (IP20) or i550 protec (IP66/IP55), the i550 motec is particularly suitable for motor mounting. Space-saving and easy to connect, it reduces installation costs and consumption by up to 45 kW and is optimized for consumption with a Lenze IE5 motor.
Ventilation technology
For condenser or evaporator units, the "fan packs" can also be operated with Lenze converters in selected applications. Wherever robustness, extreme temperature conditions, extended functionality, or easy replaceability are paramount, AC fans with frequency drives are preferred over EC fans. Lenze frequency drives are particularly well suited for these applications as they offer high temperature resistance and flexibility in installation.
