STA 5-A brine temperature control

Cooling system for high-end electronics and antenna systems

Weiss STA 5-A brine temperature control units have been developed to cool high-end electronics and antenna systems. The STA 5-A modules are extremely compact in design and therefore require little container space. The controller module can be integrated into a 19” rack and controlled from the operator room. Even at extreme temperatures from -40°C to +55°C, the system reliably cools a constant water-glycol volume to +5°C. Cooling capacity is up to 11 kW.


  • Split system consisting of capacitor module, compressor module and controller module
  • Very compact design, so requires little space in the container
  • Active cooling, even at -40°C environmental temperature
  • Possible to install on track system, hence easy access for maintenance work
  • Service and maintenance-friendly construction, hence easier component replacement
  • Easy operation through separate controller module from operator room possible
  • Possible to integrate controller module in a 19” rack
  • Reliable cooling even at extreme environmental temperatures

Scope of supply

  • brine temperature control system
  • mounting kit
  • connection lines
  • control unit
