Tin Whiskers

By John Peterson | Apr 06, 2017

Tin whiskers form when tin plating on component leads is under pressure.  The tin squeezes out to form filaments as thin as a human hair.  The whiskers grow long enough to potentially cause a short circuit.  This concern has come about since the European Union adopted restricition of hazardous substances, which has led manufacturers to […]

CRAC vs. CRAH

By John Peterson | Feb 06, 2017

I had this come up recently… what is a CRAC (pronounced ‘crack’)?  What is different from it than a CRAH (pronounced ‘craw’ or ‘cray’)? CRAC = Computer Room Air Conditioner A CRAC is often thought of as having an internal compressor, thus not needing the support of a centralized chilled water system.  But this also […]

What do we want from CFD?

By John Peterson | Jan 06, 2017

Computational Fluid Dynamics (CFD) analysis of data centers has been going on for some time, but how does it help us?  For an existing data center, do you want a CFD model to show you things you already know, such as hot or cold spots? 90% of the time we are using a CFD report […]

Cooling Tower Water Storage

By John Peterson | Dec 06, 2016

When operating your data center, often there are backup measures to keep things running during a power outage.  Generators may be the first thing that comes to mind, as they bring power back during an outage, but along with that the cooling systems also need operate.  As the heat is rejected through the mechanical systems, […]

Energy Management Systems

By John Peterson | Nov 06, 2016

Have you heard the phrase ‘you can’t manage what you can’t measure?’ This is true for your data center, and having an energy management system in place with your hands on the reigns gives you a good means to measure and manage. An energy management system (EMS) is to let you see where your energy […]

Warmer Chilled Water on Existing Systems

By John Peterson | Oct 06, 2016

So we are looking to save energy, and one of those ways is increasing the chilled water temperature.  But how does that save anything?  Increasing the chilled water temperature brings it closer to the condenser water temperature and thereby reduces the amount of work (lift) a chiller has to perform.  Since the chiller usually has […]

Glycol & your system

By John Peterson | Sep 06, 2016

Using glycol for your chilled water system will have dramatic effects and understanding how painful it can be to your efficiency is a must. Why are we using glycol? In most applications the use of glycol is to lower the fluid (most often water) freezing point. The more glycol that is used, the lower the […]
