Grounding a device generally serves two purposes. The first is to provide a safe path for current flow in the event of a short circuit. The second is to provide a true “zero voltage” reference for the circuit.

SCFM is an acronym for Standard Cubic Feet per Minute. Whether it is supplied by a fan, blower, or compressed air line, the volumetric air flow rate is simply stating the volume of air passing through over a given unit of time.

Since heaters usually play an integral role within the application, any failure can rapidly expand to a major issue or shutdown. Many of these disasters can be avoided by increasing the mean time between failures!

When designing an electric heating system for industrial processes, important factors routinely include required power, location, ducting, air source, and controls, but circuit protection is often overlooked.

As we study heat transfer and any thermal system, we will need to consider the three types of heat transfer, which are conduction, convection, and radiation.

Duct heaters made by TUTCO-Farnam are not for HVAC use. They are for industrial type applications and are not built to the standards required for the typical residential HVAC.

What is the difference between a distributed wattage heater and a zoned heater? Almost any heater that uses a wound coil can use one of these construction methods of controlling watt density.
