DFC clutches are capable of speeds up to 1200 rpm and thermal horsepower
dissipation of up to 10 horsepower.
One-eighth-inch copper tubing was helically wrapped around, and silver-soldered to, a 1/4-inch-outside-diameter copper "flame tube." The first helical test boiler weighed 8 ounces and produced 5 to 7 thermal horsepower
of superheated steam at 80 pounds per square inch and 700 [degrees] F.
In the case of selections in which the thermal horsepower
rating is exceeded by the actual load, a fan or heat exchanger, or a larger reducer may be required.
Oil-shear tension-control brakes with forced lube cooling are rated up to 27,000 ft-lbs slip torque and 1500 thermal horsepower
. Standard clutch brakes are rated up to 24,000 in-lbs and 25 thermal horsepower
A note of caution when selecting a worm-gear reducer: if the manufacturer lists thermal horsepower
ratings as well as equivalent horsepower ratings, do not confuse the two.
