NICHOLSON INDUSTRIAL STEAM TRAPS
S Types for Every Heat, Power and Process Application
A survey of large users of Nicholson industrial steam traps showed these main reasons for the increasing standardization on Nicholson units for specified appli cations :
1) Operate on lowest possible tempera ture differential; no waterlogging.
2) Have 2 to 6 times average drainage capacity.
3) No need to change or adjust valves for varying pressures. 4) Record low for steam waste.
5) Maximum air-venting capacity.
Nicholson installations have repeat edly shown production increases up to
30 per cent. Some typical unit applica tions: plastic moulding platens, dry kilns, steam mains, unit heaters, radia
tors, pipe coils, drips,.hot water heaters, driers, jacketed kettles, cookers, coffee and hot water urns, dish heaters, vege
table steamers, bakers' proof boxes, steam tables, sterilizers, ironers, presses, mangles.
Types A, AHV and AU, shown on this page, are for pressures from vacuum to 200 lb. Bronze construction, aluminum painted. BULLETIN 152.
