Heater/chiller units offer configurability and compactness via a single combined package. The integrated system saves space because both circuits are contained in one cabinet and are managed by a single controller.
In the 1960s, the steel production industry sought a way to filter the cooling water used to cool steel production. During production, both free solid material from the line, and residual oils from previous formation steps, would be on the materials being cooled.
When treating wastewater, sludge and digestate, it often can be beneficial to reduce the volume of material or increase the solids content as well. Mechanical dewatering via a centrifuge or belt press — to separate solids and liquids — is standard for the water treatment and anaerobic digestion sectors.
Compare and understand the most common calcium carbonate scale prediction methods for cooling waters. Learn where and why some methods are inaccurate, and understand how an accurate prediction method can optimize a calcium carbonate scale-control program as well as provide a cost reduction in cooling water treatments.
ASHRAE and the International Institute of Refrigeration (IIR) established definitions for five refrigeration keywords: cooling, refrigeration, chilling, freezing and cold chain. The definitions are the result of more than a year of discussions and were established to clarify the meaning of basic terminology.
When compared to space cooling, process cooling — or the removal of heat from the fluid that serves water-cooled equipment used in a manufacturing process — is a bird of a different feather. Interesting though — and the source of some fascination among those in the cooling trade — is that much of the equipment, tools and techniques remain the same.
The mechanical rooms in large multi-building industrial facilities are the hub of process temperature and climate control. Areas such as central utility plants, boiler and chiller rooms, mechanical and electrical rooms, and fuel rooms house myriad process cooling and heating equipment as well as systems for comfort heating, ventilation and air conditioning equipment and systems.
Shell-and-tube heat exchangers — first introduced in the 1900s — have long been used in all types of process applications because of their robust design. Shell-and-tube heat exchangers are able to withstand high pressures and temperatures, and these features are among the reasons for their wide use.
A portable, clean-in-place pump system, Model GDS-100 is suited for larger descaling cleanings to remove limescale, calcium and mineral deposits, rust and other contaminants found on process manufacturing equipment.
