Three key ways to save energy are the use of thermostats to control the fans, switching to LED lighting and using EC (electronically commutated) fans.
The first and most simple product to achieve energy savings is a normally open thermostat. Using a thermostat ensures that the fan is only running when actually needed which results in an extended lifetime and obvious savings in terms of energy usage. Furthermore, the filters within the fitted filter fans will also therefore have an extended life – reducing the need for replacement, saving money and reducing waste. From a maintenance point of view this will save time and potentially a tank full of diesel if the engineer needs to make a journey off-site to replace the filters.
LED enclosure lights are fast becoming the norm these days; they are more reliable, robust and use less energy. There are additional benefits from the fact that they generate little heat and require almost no maintenance once fitted. The environment will also benefit as breaking a standard florescent tube releases toxic mercury as well as phosphor.
The latest energy saving EC fans are beginning to make an appearance within enclosures. A standard 120mm x 38mm AC panel fan uses approximately 22 watts whereas the equivalent latest EC type uses only 4 watts. Based on a calculation of 0.14p per kWh running 2 x 22w fans for 24 hours a day would cost £53.16 per year. Using the same calculation for the 4w EC fan would cost £9.60 per year. The savings are significant; pay back is quick and more importantly ongoing for the rest of the product’s life cycle. The refrigeration industry has quickly moved to this type of technology and many large retailers are making substantial savings on energy costs as a result of this move.
