Heat Rejection: Which condensation technology is best?

During the refrigeration or industrial cooling cycle, heat is extracted from a cold system and thus needs to be rejected to a hot system. In order to achieve this, there are many heat rejection methods, and ARANER are specialists in the top 5 condensation technologies for heat rejection. First, the [..]

Banned refrigerants: Which ones will no longer be available in 2020?

The Montreal Protocol is an international agreement designed to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). The agreement, finalized in 1987, is designed to protect the ozone layer which filters out harmful ultraviolet radiation. Ultravi[..]

Industrial Process Refrigeration: An In-Depth Look at Each Component

The refrigeration cycle removes unwanted heat from one place and discharges that heat in another area. The process is accomplished, in short, by the pumping of refrigerant through a closed system. This system is composed of several components which enable the process to work.
