What You Need To Know About Industrial ... - JC Younger

May 17, 2016 The air, now hot, leaves the chiller. The industrial machines will use fans to pull cool air from outside and eject hot air from the chiller. You may see some small condensers using gravity to move the air. Designs can come with horizontal or vertical discharge vents, and this will contribute to the shape of the chiller and where you can put them.

Cooling Technologies and Industrial Noise Management

Most industrial plants also include various types of cooling systems in addition to the actual production part: evaporative towers or condensers, dry coolers, adiabatic coolers, chillers, etc. In some cases, this equipment must comply with stringent noise limits, especially in relation to their power and size. Current technology enables us to achieve optimal sound levels: therefore, it is ...
