Depending on the industry and specific environment, different rooms will have different cleanroom classification requirements. There is a litany of information out there regarding how classifications are tested and determined, but not as much about how to improve a specific room’s classification ranking.

There are many components within today’s coal-fired power generation plants. For these components to operate with maximum efficiency, one must do everything possible to minimize the risk of failure. One element of critical preventative maintenance is keeping everything at a temperature that will not cause instrumentation to freeze.

The ABCs of VFDs

Inside of plants today, AC motors are becoming the industry standard. Many plants are shifting to AC motors from hydraulic motors and in some cases DC motors when powering heavy loads, which were more popular in the past. This shift can be attributed to a variety of reasons and most have to do with cost.

Pipe and Valve Selection

When selecting the pipes and valves to be included in a cooling system, it is important to understand the options available — and the possible outcomes associated with each selection. The selection process is often overlooked or is not given proper attention by designers and contractors. Many factors can impact the effectiveness, longevity and quality of the overall cooling system.

Just as sound can have negative effects on the human body, certain frequencies can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

Rule of Thumb for Control Valve Sizing

When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.
