Evaporator tubes are specifically designed to efficiently boil off process fluids from the outside of the tube. This is most commonly used in chiller evaporators, where the boiling of refrigerant creates rapid cooling of the water in the tube side for use in comfort cooling as well as process cooling, depending on the specific chiller's application.

Rifle Tubing technology involves using a “rifled” or “ribbed” tube instead of smooth tubes currently used in boilers that produce steam for SAGD. The internal ribbing of rifle tubes introduce centrifugal force in the tubes, not present in traditional, smooth tubes, helping to turn water into steam uniformly and more efficiently.
