Indirect outside air conditioning unit F-COOL NEO Energy-saving cooling method using outside air indirectly Water supply not required for cooling water or vaporization Necessary infrastructure is only electric power Utilization of outside air with hybrid system- Annual rated cooling power of 25 kW and 40 kW- Copes with high-humidity environments Indirect air usage methodShuts out causes of corrosion from the outdoors Utilization of outside air throughout the year EEC's Data Center & Telecom Insight Blog There are a few important questions that facility and data center managers need to ask themselves to make sure they are on the right track in terms of timely and proper computer room air conditioning (CRAC) equipment maintenance;

these include: What maintenance needs to be done on the equipment? Preventive data center maintenance is the best approach a company can take to limit the amount of downtime on equipment in critical environments. Within the CRAC system the most common failures tend to be high temperature or high head failures - both of which can be prevented by changing air filters frequently as well as by power washing the condenser to maximizer air flow and to maintain the operation of the unit. , "Best practices for maintaining a data center CRAC unit". This article reviews several best practices that are important for maintaining your data center CRAC unit. Here are some of the items it covers: Cooling is too critical to leave to chance Fear of intentional cooling shutdown What CRAC unit maintenance should entail Taking care of mechanical items The importance of refrigerant levels, electrical testing Making time for external maintenance Be sure to take a look at the article, it offers some great information in regards to maintaining your Computer Room Air Conditioning units.

And don't forget - performing maintenance can help you save energyPerforming maintenance can also help equipment run more efficiently, which in turn helps with the longevity of the equipment, but more importantly saves money by reducing the amount of energy the equipment uses. Scopes of work to help equipment run more efficiently should include regular checks of the quality of fluids, frequently changing air filters, and power washing condenser coils to name a few. Checking fluids is essential because contaminants can result in diminished performance. Changing filters frequently is important because it will maximize the airflow in the equipment. One of the most important maintenance checks on CRAC equipment is regularly cleaning the condenser coils. Condensers are known to draw in dirt, pollen, and other debris that restricts airflow and reduces efficiencies. According to the Consortium of Energy Efficiency, facilities in which proper computer room air conditioning preventive maintenance is completed will use approximately 15% to 20% less energy than those where systems are allowed to deteriorate.

With the high cost of energy it is crucial to maintain the equipment in a data center in order to take advantage of efficiencies and save money. Companies should work with their maintenance provider to develop a scope of work - with the exorbitant cost of downtime, a strong preventive maintenance program is not an option - it's a must! data center energy management, data center preventive maintenance Contact us today for a data center assessmentSTULZ is the world's leading solution provider of energy efficient temperature and humidity management technology, specifically for mission critical applications.
