ClimaCheck Performance-analyser 8:7 is a specialised “intelligent” data collection unit specially developed to facilitate cost effective supervision of refrigeration-, air-conditioning units and heat pumps together with the ClimaCheck software. The unit is a versatile data logger that can be used for performance control of almost any type of compressor based refrigeration process. Performance Analyser is available as DIN mounted unit or as a complete field service system. Communication with the Performance-analyser can be done through direct, modem or internet connection. The unit has an advanced integrated alarm function.
Performance control Performance evaluation and detection of wear or problems with any of the component in the systems can be done with the ClimaCheck software based on the measurement in the refrigeration circuit and calculation with thermodynamic
