Calculating Melter Power Requirements
Before locating the melter on the production floor or attaching hoses and
applicators to the melter, you must calculate the electrical power required by
the hoses and applicators and confirm that the required power does not
exceed maximum allowable wattages. Properly calculating melter power
requirements will prevent damage to the melter and identify the maximum
allowable distance between the melter and the point at which the hot melt is
dispensed.
The following three maximum wattages must be considered when calculating
melter power requirements.
S Single‐component maximum—The wattage of any single hose or
applicator
S Hose/applicator pair maximum—The combined wattage of any
hose and applicator (hose/applicator pair)
S Two hose/applicator pair maximum—The combined wattage of
hose/applicator pairs 1 and 2
If your Nordson representative has already calculated the hose/applicator
power requirements and confirmed that the maximum allowable wattages will
not be exceeded, then no further calculation is necessary. However, you
should re‐evaluate the hose and applicator power requirements before you:
S add a new hose or applicator to the melter that was not factored into
the original wattage evaluation
S replace an existing hose with a higher wattage hose or an existing
applicator with a higher wattage applicator
