Impingement Heater Airflow Adjustment
1. Airflow to an impingement heater is adjusted by turning the knob on its flowmeter
located behind the lower front cabinet door. Flow is read on the gauge on the front
of the flowmeter.
2. Factors to be considered when determining the airflow include the following:
Maximum airflow is 4.0 SCFM.
Size, weight, and securing of the workpiece (high airflow can cause
movement/misalignment).
Effect of airflow on the time it takes to heat the workpiece to dispensing
temperature.
Effect of airflow on how fast the heat tooling reaches/maintains steady-state
temperature.
Ambient temperature of the dispensing area and its effects on dispensing fluid
properties (pot life, viscosity, cure time).
