The watt is an international unit of measurement of electrical power. A kilowatt is equal to 1,000 watts. The energy use of industrial machinery is commonly measured in kilowatts or kilowatts per hour. Kilowatts per hour, or KW/h, refers to the amount of kilowatts used to keep a machine running for one hour. This information will usually be listed on the machine's nameplate as KW or KW/h.
500-Ton Centrifugal Liquid Chiller
Centrifugal liquid chillers are industrial HVAC units used to cool large commercial spaces. Conventional rule of thumb says that a nominal ton of air conditioning provides enough cooling for approximately 500 to 600 square feet of building space. Therefore a 500-ton centrifugal chiller would be used to cool a 250,000 to 300,000 square foot building. This machine is rated by the manufacturer at .48 KW or 480 watts per ton of cooling. This means that this chiller running at full capacity should use approximately 240 KW or 240,000 watts per hour.
Continuous Fusing Heat Press Machine
This machine is used for industrial heat transfer. It operates continuously with constant heat and a belt speed of 8.7 meters per minute and is able to fuse materials with a width of up to 600 millimeters. This dry cleaning machines have a heater (heaters are notorious power gluttons) that is rated at 4.2 KW or 4,200 watts. It also has a motor rated at .60 KW or 600 watts. Therefore, this machine under normal conditions will consume approximately 4,800 watts per hour or 4.8 KW/h. You need to make sure you're considering the power usage of all the components of a machine when trying to find its watts usage.
400-kg Capacity Industrial Washing Machine
This machine is the type typically used in textile factories to pre-wash fabrics. It is driven by a powerful motor, rated at 11 KW or 11,000 watts per hour. Notice that there is no electrical heating element in this industrial washer. If electrical heating of any sort were incorporated into this machine, the watts usage would be substantially higher.
