Highest efficiency, smallest possible CO₂ footprint, low sound emissions and low costs − these are just some of the challenges which refrigeration unit manufacturers are faced with.
To achieve this performance, the four basic components of a chiller (compressor, condenser, expansion valve and evaporator) must be matched to each other ideally, and the control system should be designed and fine-tuned for the specific application. Each regulation system is only as good as its individual components.
In the case of measuring instruments, this means that accurate measurement is needed in order to be able to operate the plant efficiently. In addition to their accuracy, instruments should feature additional properties, such as resistance to weathering, condensation and media, to ensure that a chiller can withstand, for example, 365 days per year on a roof, exposed to the elements.
Not all measuring instruments have a direct influence on the control. The plant itself also requires maintenance at regular intervals in order to provide reliable service for many years. For this, reliable measuring instruments for monitoring the condition of various elements, such as the engine oil, are indispensable tools.
