KRY -40 ~ +100°C 1&2 EV Cooling System
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
Multi Channel Temperature Control
KRY series automotive test chillers support multiple channel temperature control
- Independent flow and pressure control
- temperature, flow and pressure are controlled independently.
Display Function
