Nicholson Steam Trap

About Nicholson: Nicholson Steam Trap was founded in 1883 by W.H. Nicholson, Sr., who produced a variety of steam specialty products in Wilkes-Barre, Pennsylvania. In the 1930’s, Nicholson developed a wide range of bellows-activated thermostatic traps that are the basis for designs built today. Nicholson's Steam Trap product line varies from highly polished stainless steel sanitary traps to variable orifice float & thermostatic (F&T) traps. Steam traps and condensate pumps are designed for industrial applications such as condensate systems, district heating, main steam systems, process control, and process heating.
