Adiabatic Coolers: An Evolution in Sustainable Process Cooling

By Eric Thompson, General Manager, Frigel North America

Adiabatic coolers are rapidly gaining ground in plastics processing as manufacturers seek sustainable, energy-efficient alternatives to traditional cooling towers. By operating in dry, adiabatic and free-cooling modes, modern systems engineered by Frigel North America deliver up to 90% water savings, lower energy consumption and improved temperature stability for injection molding, PET, extrusion and thermoforming applications. With reduced maintenance, closed-loop protection and long-term ROI advantages, adiabatic cooling is emerging as the new benchmark for high-performance industrial process cooling.

Energy Saving and Air Changes

By Raul Simonetti, HVAC/R Corporate Business Manager, Carel Industries

Current ventilation guidelines recommend maintaining ventilation with 100% outdoor air 24/7, or as much as possible if that is not feasible, as an effective way to keep airborne pathogen concentration under control. Obviously, outdoor air needs to be filtered and conditioned to guarantee the indoor temperature and humidity set points; this, in turn, implies a higher HVAC-related primary energy consumption, because more outdoor air needs to be conditioned compared to the pre-COVID-19 situation, when the flow of outdoor air was typically 20% of the total supply air entering the space.
