Optimize Cooling Water Supply To Reduce Distribution Costs
Reducing distribution costs for cooling and chilled water is often one of the easiest and quickest methods of reducing energy use in water cooling, yet most plants have never investigated this area.

Optimize Cooling Water Supply To Reduce Costs
In the last three articles (March, May, Sept. 2012), we introduced the problem of wasted energy in cooling-water systems and presented two types of solutions—minimizing “parasitic” heat gains and raising water temperatures to minimize demand.

Energy Miser: For Energy-Efficient Water Cooling, Raise Temperatures to Cut Demand
Many plants use chilled-water temperatures that are far lower than are actually needed by the process. This has a direct effect on the cost of chilled water.

Cooling Water: Minimize Demand by Reducing Heat Gains
In March, we introduced the subject of energy savings through cooling-water management.

Compressed Air: Optimize Treatment and Distribution to Save Energy
In previous articles, we discussed the enormous waste of energy and money that occurs every day in many plants due to inefficient use and generation of compressed air.

Introduction to Cooling Water Energy Management
A reliable and consistent source of cooling is essential in plastics processing.

air compressors consume large amounts of energy

Energy Miser: Use Less Energy to Generate Compressed Air
Last month, we addressed how to minimize your plant’s usage of costly compressed air.

Cost of Compressed Air Leaks

Energy Miser: Plug Costly Compressed-Air Leaks
Last month we introduced the idea that compressed-air usage is one of the first places any manufacturer should look to reduce energy cost.

Compressed Air Isn’t Free!
Compressed air is a convenient and often essential utility, but it is very expensive to produce, and most of the energy used to compress air is turned into heat and then lost to the system and environment.

Where Are You Using Energy?
Few plants are able to accurately divide up their energy consumption by where it occurs, despite the fact that this is relatively easy to do.

External Benchmarking of Injection Molding Energy Efficiency
In April, we discussed the use of the slope of the curve of process energy consumption versus production volume for internal benchmarking of energy efficiency.

Internal Benchmarking: Setting Targets
Last month, we discussed how to graph your plant’s “process energy fingerprint.” Now we’ll show you how to make use of that information.

What’s Your Process Energy Fingerprint?
As we discussed in last month’s column, your plant’s “energy fingerprint” is composed of the base load and the process load.

Know Your Plant’s ‘Energy Fingerprint’
It is commonly thought that energy use in plastics processing is fixed and uncontrollable.
