LUETZE’s AirSTREAM wiring system is designed to optimize climate conditions inside control cabinets. As components become more compact and generate more heat, traditional cooling methods often fail to prevent hotspots. The AirSTREAM system ensures even air distribution, reducing thermal loss and preventing localized overheating. This results in fewer failures, less downtime, and extended component life.

The LUETZE AirBLOWER improves climate control in control cabinets by eliminating air layers and ensuring even temperature distribution. When used with an AirSTREAM frame, cooling efficiency increases significantly, with tests showing temperature reductions of up to 10 K. Consuming far less energy than active cooling systems, the AirBLOWER can be operated only when needed, providing an energy-efficient solution for thermal management.

The LUETZE AirSTREAM wiring system is engineered with a modern design principle, offering both construction and operational benefits for control cabinet installation. Its high-strength aluminium frames integrate wiring trunking directly into the frame, allowing compact installation of multiple components in tight spaces. Wiring is comfortably installed from the front, and the open design ensures continuous airflow around components, efficiently removing heat and improving cooling performance.

The LUETZE LUNA is an intelligent control system for 2-pole switching and load monitoring of 24 V actuators. It provides adjustable current ranges up to 10 A with configurable tripping characteristics from fast-acting to super slow. Each module includes 2 channels and supports permanent transmission of diagnostic data. Designed for railway applications, LUNA connects to the vehicle control unit via Ethernet TRDP and is available as a compact module with 6 or 11 slots.

The LUETZE Logic Modules enable the realization of logic operations with or without software. Featuring 8 digital potential-free wide-range inputs with individually selectable thresholds (9 V / 33 V) for nominal voltage DC 24–110 V, and 4 digital potential-free wide-range outputs with short-circuit protection, they offer flexible control. With a maximum output current of 2 A, wide-range supply voltage of DC 24–110 V, and status LEDs for each input and output, the modules ensure reliable monitoring and operation in demanding railway environments.
