1 Lock-Temp Storage TanksLochinvar Lock-Temp Tanks have been specifically designedand engineered to provide a high volume supply of hot water at aconstant outlet temperature. The unique Lock-Temp bafflechamber design is so efficient that, regardless of the rate of hotwater flow, 80% of the stored volume of hot water can be drawnfrom the storage tank without a drop in the pre-set 1/3 less hot water storage is required with Lock-TempStorage Tanks than with ordinary storage tanks, there are severalimportant economic features to consider:Lower Standby Losses,Smaller Footprint Required, Lower Installed Cost, ReducedWater Heater Operation operation, Lock-Temp Storage Tanks utilize a unique waterbaffle chamber to eliminate turbulence and establish a positive,piston-like displacement system.

2 Cold water entering the systemis directed into the built-in baffle chamber, where waterturbulence is eliminated. Eliminating turbulence allows naturalphysical properties to force hot water to the top of the tank andcold water to the bottom. The resulting effect creates nearlyperfect stratification allowing the hot water to be drawn from thetank Lock-Temp system makes Lochinvar Storage Tanks moreefficient. Consider that a typical storage tank delivers only about60% of its stored water volume at the desired temperature whileLochinvar tanks with the Lock-Temp baffle deliver a minimum of80%. This efficiency allows for more economical sizing ofstorage tanks.

3 A design calling for 400 gallons of 180 F waterwould require a 670 gallon standard tank while a Lock-Temp tankwould deliver the same 180 F volume using only a 500 gallontank. A 170 gallon ordinary storage tanks, water circulation or a heavydraw of hot water from the top of the tank causes anincoming rush of cold water, creating turbulence in thetank s stored water supply. The result isinter-mixed hot and cold water that requires constantadjustment at the fixtures to maintain the desiredtemperature. Lochinvar Lock-Temp Storage Tankseliminate these problems with a unique inner chamberbaffle that absorbs and flattens turbulence caused byincoming water.

4 The Lock-Temp baffle also permitshot and cold water to stratify, directing the hottestwater to the top of the tank and the colder water to thebottom for return to the of a Lock-Temp storage tank over conventional storage tankLock- temp Design locks Hot Water at Top,Cold Water at , Jacketed & Insulatedor Bare ASME TanksAn ordinary 180 gallon tankand a 180 gallon Lock-Temptank were compared at a setwater temperature of 180 was withdrawn at a rate of12 GPM under controlledconditions. The Lock-Temp tankprovided 141 gallons of water atset point and the conventionaltank only provided 30 gallons ofwater at set point before thedelivery temperature droppedbelow 180 FHydraulic Plate RollThe plate roll turns a flat plate of steel (up to 1/2 thick) into a round cylinder.

5 CNC Laser Cutting Control PanelTo provide the greatest accuracy the CNC lasercutting machine uses PLC controls. Allprogramming is performed in-house and storedin the shop computers. Submerged Arc Longitudinal Seam WelderAs the welding head travels 28-30 IPM, thewelding wire penetrates the steel to form a full-penetration weld on both the inner and outersurface of the tank WeldTank heads and fittings are tacked and weldedinto the tank shell by ASME certified Arc Circumferential WelderHere the submerged arc welding process welds the ends on as the tank rotates. A full-penetrationX-ray quality weld is made in two to four Shot BlastingAll internal surfaces are blasted to a white metal,removing rust, scale, greases and oils so liningcan have optimum adhesion.

6 Million BTU Intermittent glass FurnaceAfter a drying process, the tanks enter the furnacemodule. The glass lining is fired at 1600 F tocreate a molecular bond between the glass fritand the vessel s steel surface. This is the largestindexing furnace in the United QualityThe ASME inspector then administers tests for leaksand other nonconformances. Magnesium anoderods are provided with each glass tank to protectthe integrity of the TestingUpon completion of the manufacturing processes,each tank has all threaded openings tapped andcleaned. The tanks are then filled with water andbrought up to the designed working pressure.
