Warehousing and cold storage
Refrigeration and lighting are often the biggest energy guzzlers for cold storage and warehousing facilities.
In these environments, even actions as simple as shutting the door can lead to significant savings. Installing automatic cold storage doors and well maintained seals can reduce your overall energy use and extend product life.
Top energy-saving tips
Refrigeration: Save 30 - 80 per cent
Refrigeration and chilling
Maintaining refrigeration equipment, upgrading heat exchangers and insulation, checking regularly for leaks, and installing/upgrading thermostats can help reduce energy use.
Motor speeds: Save about 50 per cent
Variable speed drives (VSDs)
The installation of VSDs on machinery with motors such as compressors, pumps and fans can make a big difference to energy consumption. Evaporative fans for cold storage, for example, are often necessarily large to ensure maximum cooling, but are often kept running at the same speed even when optimum temperatures are achieved.
LED lighting: Save up to 70 per cent
Investing in the latest lighting technology can often provide a quick win – with short pay back periods often achieved through a combination of lower power consumption and significantly reduced maintenance requirements. Add sensors and timers to stop money being wasted lighting areas that are not being used.
Submeters are a cost effective way to identify thousands of dollars in energy savings opportunities. They can provide you with sophisticated data about your site’s energy use that a standard utility meter cannot. Submeters can reveal operational inefficiencies such as identifying equipment that is running unnecessarily. This data can help you to compare and benchmark usage across similar facilities and over time.
