Normally industrial installations require functional lighting and we therefore tend to put in our LED floodlights which offer a good light with little power draw. However, other styles are available if preferred.
Heating is normally provided using indirect diesel fired heating which sits outside the marquee and blows hot air through ducts. If the marquees are within confined spaces e.g. within factory units or sheds then electric heating can be provided instead. All heaters are thermostatically controlled and can be run of bulk tanks to ensure plentiful supply of fuel.
