KRIWAN油位调节器INT280-60系列介绍
INT280-60 诊断是可靠的 KRIWAN 油位调节器的进一步开发。
油位调节器 INT280-60 Diagnose 监视和控制制冷剂压缩机中的油位。通过主动从储油器供油，克服了多压缩机组中油分布不良的问题。这可以最大限度地降低压缩机内没有足够油的情况下运行的风险。
INT280-60 诊断将操作和错误数据保存在非易失性存储器中。可以读取和评估这些数据以进行诊断。
The INT280-60 Diagnose is a further development of the reliable KRIWAN oil level regulators.
The oil level regulator INT280-60 Diagnose monitors and controls the oil level in the refrigerant compressors. The problem of poor oil distribution in multi-compressor packs has been overcome by actively supplying oil from the oil reservoir. This minimizes the risk of operating without enough oil in the compressor.
The INT280-60 Diagnose saves operating and error data in a nonvolatile memory. This data can be read and evaluated for diagnosis.
