from money pits
Frequent break-downs and continuous replacement of air conditioners made a Telecom operator consider a new supplier. The result was a more affordable, more reliable and more energy-saving Heat Exchange solution from Dantherm.
Frequent air conditioner break-downs and high running costs
A Telecom operator based in Western Europe was having problems with air conditioner break-downs. In some cases, it would even be impossible to start the aging units. With more than 600 cabinets, the result was very high costs on running, servicing and continuously replacing the air conditioners.
Dantherm-investigation changed original plans
Initially the operator was looking for a similar, more reliable AC Air Conditioning solution. But when inspecting the site, the Dantherm consultant recommended to cool the cabinet solutions with DC Heat Exchange instead of Air Conditioning. The recommendation was supported by a calculation comparing the heat exchanger with a new, fully functional air conditioner, which showed possible energy savings of 85 %.
Heat Exchange vs. Air Conditioning in outdoor cabinets
So what was the idea behind changing solutions? Because of the Heat Exchange technology, the inside temperature would only be slightly higher than that of the outside environment, when removing heat instead of cooling. Therefore, there was no need for highly energy-intensive Air Conditioning. Furthermore, the start-up inrush current and great need of AC power which led to the problems of high running costs and frequent break-downs of the original Air Conditioning solutions would be eliminated, because the Dantherm Heat Exchangers are significantly less power consuming. Finally, Heat Exchange solutions are generally more affordable than traditional Air Conditioning solutions and much easier and thus cheaper to service.
Improved uptime and increased savings
The operator agreed to initiate a test-run of a Dantherm Heat Exchange solution at a selection of sites. The tests ran for more than a year, during which time the operator decided to roll out the solution in more cabinets across the country. The Heat Exchange solutions were even installed without powering down the operator's sites, thus avoiding unnecessary downtime.
By changing from active cooling to a more reliable passive cooling solution, the operator reduced costs on equipment, power consumption and service visits. Finally, he improved the customer experience of his own end users by avoiding downtime due to break-downs.
