The Varistar LHX+ electronic cabinet, including air/water heat exchanger with 5 kW or 10 kW cooling capacity, is well-suited for applications where a fully sealed cabinet is required.

Cooling Concept

• 19-inch heat exchanger (6 U) installed in lower cabinet section
• Scalable cooling performance
  – Double fan unit for 10 kW cooling performance
  – Single fan unit for 5 kW cooling performance
• The fan units can be exchanged without having to replace the heat exchanger
• Air flow volume of ~ 1000 / 1800 m3/h
• Water flow temperature from 6°C to 25°C
• Ambient temperature from 5°C to 50°C

Features

• Scalable: By replacing the heat exchanger with an integrated fan with a heat exchanger with two fans, the cooling performance can be modified from 5 kW to 10 kW. The infrastructure in the cabinet stays the same.
• Future-oriented: When the number of complex electronics in the cabinet increases and the power density along with it, only the heat exchanger must be replaced to achieve higher cooling performance.
• Hot-swap applicable: EC fans with speed control can be maintained without tools and even replaced in ongoing operation.
• Space-saving: Available starting at 600W x 800D base area per cabinet.
• Precision control: Controller with precise temperature regulation accuracy of +/- 0.1°C.
• Greater productivity, higher safety: Heat exchanger control directly at the cabinet via the display on the door. Remote access control with EtherCAT, Ethernet/IP, Modbus, or Profibus is also possible. Web server access optional.
