Keeping power equipment cool and dry in outdoor telecommunication plants has always been a problem for telco companies. Traditional cooling systems such as air conditioning are expensive to run, add to a company’s carbon footprint and require regular maintenance. To address this problem, Eltek has developed the Eltek Cooling Box (ECB), a solution that incorporates an optimised thermal system controller, passive free air cooling and a highly efficient fan and filter mechanism that will keep sensitive electronics functioning even in the harshest conditions. This cost-effective solution has a uniquely flexible cube design that allows multiple mounting options (with different airflow paths) to meet the demands of different shelter layouts while maximising cooling performance.
All data and events can be tracked using the Eltek Smartpack controller’s data-logging function, which allows users to view items such as temperature curves, fan speed, filter blocks, system failures, etc. The ECB has the advantage of being able to filter/exchange a large amount of ambient air (>2000 m3/h), giving a very high cooling performance with low power consumption while maintaining the internal environmental temperature, dust and humidity. The ECB comes with aluminium and galvanised steel construction, is lightweight, easy to install, and has a fan-speed control that allows users to set it from 0-100%. Other key features include delta ΔT tracking, alarms, local/remote site monitoring capabilities, and even the option of controlling the existing air-con system.
