The Modulatic is a once-through waterube boiler with a positive displacement pump to provide a constant flow of feedwater.The pump is controlled by a variable speed drive that regulates the amount of feedwater that is sent to the coils in response to changes in steam pressure.

The servo control changes the amount of fuel and combustion air in direct proportion to the flow of water being sent to the coils. Dry steam is then produced in the steam separator. The water remaining is removed by a steam trap.
