Features of Vehicle Test Chillers

  • Multi channel output, independent control of flow, no interference with each other.
  • Temperature, flow and pressure can be controlled separately.
  • Multi channel temperature control, and one device can achieve multi channel output, and control the flow separately.
  • Strong circulation pump ensures the delivery of high viscosity liquid, it can provide high flow under stable pressure.
  • Clear circuit, compact structure, multiple fault alarm functions to ensure safe operation of the equipment.
  • Temperature variation range is usually from -40 to 100 degrees (which can be extended to 150 degrees). While controlling the temperature, you can also choose to control the flow or pressure.
  • Equipped with powerful circulating pump to ensure the delivery of high viscosity liquid; Variable frequency regulation or proportional regulation valve is used to control the flow output to achieve high-precision control of 5% ~ 100% of the total range.
  • The temperature control equipment can be flexibly connected with other test platforms.

Advantages of Vehicle Test Chillers

automotive chillers

Multi Channel Temperature Control

KRY series automotive test chillers support multiple channel temperature control

  1. Independent flow and pressure control
  2. temperature, flow and pressure are controlled independently.

Display Function

  1. Display all the kind of process control temperatures.
  2. Shows the liquid level of the heat conducting medium in the expansion vessel.
  3. Shows indication for refrigeration system working.
  4. Shows indication for heater working.
  5. Shows indication for circulation pump working.
  6. Display the temperature control.
  7. The temperature upper limit, lower limit control can be set.
  8. The temperature difference between jacket & reactor material can be set.
  9. Shows the alarm to add the liquid when it is empty.
  10. The refrigeration compressor can be set to operate manually or automatically.
