Power usage monitoring in facilities with power-hungry equipment can perform an important role in ongoing energy efficiency policies.

For example, regular monitoring with Gemini Data Loggers’ Tinytag Energy Logger has proved effective for European Freeze Dry, a leading multi-product freeze drying facility and speciality freeze drying services provider. European Freeze Dry monitors the energy consumption of all plant and equipment at its site: the Energy Logger is used in 24 hour periods on equipment such as vacuum pumps, vacuum boosters, air compressors, pumps etc. The recorded data is analyzed to identify areas where usage or loading of equipment can be reduced. Where modifications to systems or practices are implemented the equipment will then be monitored again to quantify savings and efficiencies.

The Tinytag Energy Logger costs £795 +VAT, and is a safe and easy to use tool for monitoring single and three phase power usage. The portable, self-configuring device can be used for spot-checks or for longer term recording. Non-invasive flexible coils are used to monitor the current in each phase of a three phase supply while the voltage information may be obtained via a standard 13A wall socket.

Similarly, Hampshire-based Celab is a relatively high user of electricity, typically 55,000-70,000KWH/month. Celab designs and manufactures high reliability power supplies for military and commercial applications. With 2000m2 of manufacturing space housing a variety of equipment and processes, Celab purchased an Energy Logger to understand the power usage of individual pieces of equipment and to help identify where potential energy usage savings can be made. 

Gemini Data Loggers has been designing and manufacturing the Tinytag range of data loggers in the UK since 1992 and trades globally with a network of over 40 distributors.
