KRY -25 ~ +100°C Automotive Chillers

Features of Vehicle Automotive 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 Automotive Chillers
