In addition to our traditional pulse combustor and atomizer combination, PCS now offers three new ways to heat the atomizing and drying air. These are:
- Electric. In Electric Mode, the atomizing and drying air is heated directly by passing it over electric heating elements. A process blower pressurizes the air up to about 4 psi, and pushes it through the heater. The atomizing and drying effect is almost identical to that achieved when using our traditional pulse combustor. The advantages are:
a. Zero emissions from burning of fuel
b. Zero nitrates in powder
c. Equivalent or better powder quality
d. Easiest of all Pulse Atomizing Dryers to operate
e. Very low maintenance costs. - Duct Heater. In Duct Heater Mode, the atomizing and drying air is heated directly by passing it through a duct having a natural gas burner. As with the electric mode, a process blower pressurizes the air up to about 4 psi, and pushes it through the heater. The atomizing and drying effect is almost identical to that achieved when using our traditional pulse combustor. The advantages of the Duct Heater are:
a. Equivalent powder quality
b. Equivalent thermal efficiency
c. Second-easiest of all Pulse Atomizing Dryers to operate
d. Very low maintenance costs.The Duct Heater is also available in a Low NOx configuration. - Indirect Gas-Fired Heater. In this configuration, the Duct Heater is replaced by a gas-fired heat exchanger, enabling the process air to be free of products of combustion. This type of air heating is commonly used in the dairy industry. This system is also available in a Low NOx mode.
