1 Preferred Utilities Manufacturing Corp
Fuel Oil Handling Systems Overview Preferred Utilities Mfg. Corp. 31-35 South Street • Danbury • CT

2 PUMC Identity Founded in 1920 and in continuous operation since then. We are an engineering - based manufacturer of combustion and fuel handling products for industrial, institutional, and commercial power plants. Our Core Business is Combustion Control.

3 PUMC Identity

4 Plant Wide Controller Hot Water Reset Application
2 to 10 Boiler Modulating Lead / Lag

5 New Plant Wide Controller (PWC)
Displays Plant Overviews Historical Trends Alarm Summary Setup

6 PCC-III™ Multiloop Controller
Third Generation Controller 12 year PCC II life with over 2000 installed 2 year PCC III life with over 300 already installed There are many digital controller manufacturers, but NONE have Preferred’s in-depth and on going combustion control experience.

7 New WN Best Combustion System
Low NOx Low Energy Consumption Burner + Controls + BMS + SCADA = Maintained Performance

8 Complete System Expertise

9 Typical Piping Arrangement
Emerg. Gen. Day Tank Vent with Rupture Basin Fill Return Supply Suction Pump Main Oil Tank

10 Fuel Fill Spill Containers Model 1 In Ground Spill Container
Drains oil spilled from delivery disconnect into storage tank Designed to handle driveway traffic Removable bellows for easy fuel testing without pavement excavation.

11 Fuel Fill Model 2 In Wall Spill Container
For indoor storage tanks with fill lines to building walls Standard models from simple box to integrated digital level display and overfill alarming We can customize many things: A bronze Model 2 was recently installed at Radio City Music Hall to contribute to the building’s décor.

12 In-Wall Fill Box with Sign

13 Typical Piping Arrangement

17 Anti-Syphon Valves Patented by Preferred Utilities.
UL Labeled & Listed 3 million cycles to get UL approval….

18 Anti-Syphon Valve Manifold

19 Anti-Syphon Valves Used where fuel leaks will result in fuel being syphoned into areas which can cause a dangerous and costly situation UL Labeled and listed For No. 2 through No. 6 Oils 5’, 10’, 15’ or 20” Head Selection Installed at highest point in piping

20 Fire Safety Shut-off Valves
Preferred’s Lever Gate Valve Fully mechanical Emergency fuel line shut-off is mandated by many codes Fusible links open at 165F for pipe ranges 1" - 3" Fusomatic Valve Replaceable fusible element Fusible links open at 165F, May be manually opened/closed for pipes 3/4" or 1"

21 Type 110 Fire Valve

22 Foot Valves Ensures maintenance of pump prime by preventing oil backflow into the tank when pumps are off Single Poppet 1/2” to 3” Size Double Poppet Double the protection 1-1/2” or 2” Sizes Foot Valve Extractor Fitting Easy Removal and Inspection of Foot Valve

27 Fuel Components Strainers Duplex Simplex
No flow interruption for routine cleaning 90° handle movement switches baskets Handle blocks inadvertent opening of active side Sizes from 3/4" - 6" Simplex Special yoke design for quick cleaning Large basket Sizes from 1/2" - 2"

28 Pump Sets with Multiple Pumps
Multiple pumps share common suction and discharge piping Most common is duplex set two 100% pumps, one for backup control system can monitor flow, start lag pump Triplex pump sets for large plants three 50% pumps allow for one spare two 100% “winter pumps” - one 50% “summer pump”
