Chiller & Cooling Best Practices Magazine interviewed Paul Heston (General Manager) and Tom Strock (Chief Engineer) from Hydrothrift Corporation.

In a nutshell, where workers are exposed to harmful chemicals, they must have eyewash and safety shower stations to decontaminate themselves in the event of a spill or splash. A variety of industries, including petrochemical, chemical, metal fabrication and laboratories, must plan for this contingency. The ANSI Z358.1 Standard specifies the water used for these purposes must be tepid or within a site-specified range.  This means in colder climates, water must be heated, and in hotter climates water must be cooled.

 

Among key initiatives at DENSO’s Maryville, Tennessee, facility is the use of an innovative ice-storage system engineered to provide environmentally friendly comfort cooling to employees at the company’s main production facility. The system also allows Plant 101 to reduce cooling costs per ton by 44%, while providing a payback of less than four years. It also resulted in an annual carbon dioxide (CO2) reduction of 18,000 tons.
Air compressors are very effective heaters. Over eighty percent of the energy input from the motor is converted into compression heat. That heat must be rejected from the compressor package in a way that maintains a variety of temperatures in a reliable manner. The laws of physics demand that the air temperatures go up with compression.
There are three main segments in Visteon's climate group are climate systems, powertrain cooling and engine induction. Climate systems include refrigeration compressors, fluid transport, heat exchangers, battery cooling modules, climate controls, auto defog/demist systems, and multi-zone HVAC systems. Powertrain cooling systems include heat exchangers (radiators, condensers, charge-air, exhaust-gas), airflow management, and diesel and hybrid thermal management. Engine induction includes air induction systems and intake manifolds.
This article reviews two major processes in paper mills: compressed air quality and air compressor cooling.  The central air compressor room was expanded and relocated at the largest privately owned paper mill in Canada.  The compressor space was required by a plant expansion, which would occupy the original compressor space for increased production.
