How To Keep Injection Molds Clean


Leave a comment

Why Is It Important To Clean And Lay Up My Mold Tools? Water is used to cool and remove heat from the liquid plastic once it fills the mold. Cooling water flows through holes and channels drilled and cut in the mold tool. These ports in the mold tool are engineered to optimize the flow […]

Why Are Bacteria Harmful To Cooling Towers


Leave a comment

Why Is It Important To Lay Up My Cooling Tower? If left to grow unchecked, the bacteria that live in your cooling tower will colonize pipes and other wetted surfaces. Over time these colonies will grow into thick biofilms that reduce heat transfer, prevent corrosion inhibition strategies, and even cause corrosion themselves. Cooling tower water […]

What Are Adiabatic Cooling Towers?


Leave a comment

What Does Adiabatic Mean? The term “adiabatic” means “occurring without gain or loss of heat,” but applying this definition to common industry terms requires distinguishing between heat and temperature. When a gas is compressed under adiabatic conditions, its pressure increases and its temperature rises without the gain or loss of any heat. Conversely, when a […]

How Do Cooling Towers Work?


Leave a comment

What Does A Cooling Tower Do? Cooling towers are designed to take heat from one area and reject it to another. The cooling process that takes place within the towers is based on the principle of thermodynamics where heat will flow from hot to cold. Cooling towers are designed to increase the surface area of […]

How Do Steam Boilers Work?


Leave a comment

What Does A Boiler Do? A steam boiler is a type of heat exchange system where water is heated to its’ boiling point via combustion of a fuel blown through a tube submerged in water. The heat produced in this system is then rejected into the system as steam. This steam flows through pipe systems […]
