Air Power spends most of our focus working within utility programs to help our customers maximize their energy efficiency investments. Working with ComEd, we’re able to offer participation in a special program that pays for 100% of the cost of insulation blankets for injection molding machines and extrusion molding machines. We typically take a portfolio approach when presenting energy reduction opportunities. This is just one of many project areas we offer and a particularly attractive one at that. In most utility programs we can have these installed with most up front costs covered for the customer. Even outside of utility programs these projects tend to be around a 2-year payback.
An insulation jacket is best described as a blanket that covers the barrels of an injection molding machine. It’s a simple efficiency improvement process. The jacket keeps the heat inside. That means there is less heat lost and it requires less energy to maintain the high temperature of the molten thermoplastic material.
The exact energy saving variables are going to differ based on ambient temperature, product temperature, machine size and operating hours. Starting with those metrics, the machine’s eligibility for the no or low cost program.
