At some point, every lab manager has to make this choice. Your old cooling unit stops working, and you're looking at spec papers trying to decide what to do. Both air cooling and water cooling keep samples cold, but they do it in very different ways. How Labs Use Air Cooling Consider your air conditioner at home. Air-cooled condensing unit systems work in the same way. A fan moves air over coils that are full of refrigerant. The cold air moves about your storage area while the hot air is forced outside. These devices need good air circulation around them. You can't just shove them into tight spaces and expect them to work well. Most labs put them in places where there is at least three feet of space on all sides. The good news? You connect them and they work. There are no water lines to connect. No need to keep pumps running. Most of the time, any HVAC technician can fix something that breaks. How Water Cooling Systems Work Water cooling works differently. Water runs through th...

AC coupling lets only changing signals through, blocking steady ones. It's like focusing on waves in the ocean but ignoring the overall water level. DC coupling lets both steady and changing signals through. It's like looking at the ocean waves and the overall water level. In case you have been wondering what difference AC and DC Coupling make to your Air Conditioning or Refrigeration, this blog might just give you the answers to your questions. 3 Key Differences Between AC and DC Coupling  Working Principle So what is a coupling? A coupling is a mechanical device connecting two parts or objects like shafts. The first point of difference is the concept behind their functioning. In AC coupling there exists a Capacitor that blocks the incoming DC signal, i.e. AC coupling only accepts the AC signal and removes the DC offset, whereas in DC coupling the capacitor is absent which allows both DC and AC signals to pass. How Flexible Are They for Your System? HVAC units are often seen ...
