Annual savings of more than fifty thousand cubic meters of natural gas or tens of thousands of kilowatt hours are possible through heat recovery. Furthermore, when you use heat recovery, you help to reduce CO2 emissions because you consume less energy. In this way, your business is contributing to make the chain in which you are operating more sustainable. The government has introduced attractive tax incentives to stimulate the use of heat recovery. For example, with the Energy Investment Deduction (EIA) you can deduct up to 41.5 percent of your investment costs from your taxable income over and above your usual tax deduction.
Every company that refrigerates and freezes products industrially is generating a huge amount of residual heat, enough to heat a row of houses. This heat is released during the refrigeration or freezing process, and is usually discharged and lost into open air. By capturing residual heat, and where necessary, upgrading it to a higher temperature, it becomes available to other processes.
With an additional compressor on the cooling installation and the use of a heat pump system, you can upgrade low-temperature residual heat captured during the cooling process to a temperature level of 60 degrees and higher. This way, you generate so much heat from residual heat that you significantly reduce your gas and energy consumption. In some cases, it is even possible to turn off the gas supply and to heat without gas.
"Heat recovery saves costs from the start"
Your residual heat can be used in many different ways. Some companies use it to heat cleaning water to the desired temperature. Other companies use it for floor heating. There are also companies that need heat for their industrial processes for example, making cheese. With smart solutions in heat recovery, businesses are saving on energy costs, and at the same time meeting the increasing demand from their customers for clean production techniques.
Heat recovery is particularly interesting for food processing companies. This is because they require both cooling and heating of their products and processes simultaneously. With a customized solution they can respond to this in a smart way. This ENGIE solution consists of the infrastructure to capture the heat released during refrigeration or freezing. Technology is also required to use this heat in a targeted and responsible way in your company.
We guide you during the entire process of heat recovery, from drawing up a business case to actually saving energy. The process starts by calculating the residual heat released by your refrigeration or deep-freeze system, followed by a specification of how this heat can be captured and used responsibly. Lastly, we map out the adjustments that you need to make to do this. We also help you to calculate how quickly you will earn back your investment. Depending on the options, payback is possible within three years. Heat recovery can be realized without disrupting your production process.
You will soon notice that you are using much less energy!
