2 Features & enefits -2- liminate bubbles and dirt in the system before they cause trouble. ir and dirt trapped in the system can produce major problems such as reduced heat transfer, loss of efficiency, pipe corrosion, pump damage, increased energy consumption, and irritating noise. The highly efficient Taco 4900 Series separator, now with optional removable covers, clears the system of microbubbles, sand, dirt, and rust to save money, energy, and component wear Series stainless steel PLL Ring baskets can be removed by one person. Unlike many competitive models each 4900 unit is designed and constructed to the requirements of Section VIII of the SM code as standard. uropean PLL Ring technology. Taco ingenuity. The 4900 Series integral PLL ring technology has been proven in countless uropean installations. PLL rings are used in the processing industry to mix gases with, or separate gases from liquids. The use of PLL rings in hydronic air separation is so unique, it s patented. y applying PLL ring technology to air and dirt separation, the 4900 Series will: Remove microbubbles as small as 18 X 10-6 m (18 microns) from the system Remove air which has dissolved in the system s water Remove air from places where an air vent cannot be installed Remove and separate solid particles from the flow 2 PSI or less pressure drop at optimal flow rate* High efficiency cleaning of air and dirt. PLL ring technology has been used for many years in the processing industry. Taco s application of PLL rings to hydronic air and dirt separation is new to the HV industry. While air bubbles are separated by the PLL rings through a process known as coalescence, dirt particles are actually caught and sifted to the bottom of the tank, where they can be removed through a blowdown valve. The 4900 Series provides higher efficiency, with reduced pressure drops, so a somewhat smaller pump may be used for maximum efficiency. When water is brought into contact with a PLL RIN, the stream is deflected in many directions. Microbubbles attach to the ring surface, by coalescence growing large enough to be separated. Large numbers of PLL rings in the 4900 Series yields virtually air-free system water. Removable over and Stainless Steel Pall Ring asket ssembly Superior air bubble removal Series models clean the system of free air and microbubbles; Series models remove both air N dirt from the hydronic system. 304 stainless steel screens are provided on the inlet/outlet of each separator to isolate the separator s internals from the hydronic system. flushing cock allows for the cleaning of the PLL rings. full port ball valve is provided at the bottom of the unit to permit blowdown of accumulated particles. While construction of both models differs somewhat, the PLL ring operating principle is the same. * See pages 13 & 14 for optimal flow rates.

4 pplications -4- ir ontrol and limination Water contains a certain amount of entrained air. If this air comes out of solution, it can increase corrosion rates of metals within the system. In addition, air can form pockets at the top of pipes and heating units. These air pockets can actually restrict or block flow in a hydronic piping system. This is referred to as air locking. The table below shows a solubility curve for air in water. Note that at a fixed pressure, increasing the temperature reduces the amount of air that can be dissolved. For example, at 60 PSI and 40 F, the water can contain just over 10% air by volume. t 60 PSI and 200 F, the percentage decreases to just over 4%. onversely, at fixed temperature reducing the pressure reduces the amount of air that can be dissolved. For example at 100 F and 80 PSI the water can contain 8% air by volume. t 100 F and 20 PSI the percentage decreases to 2%. The highest temperature in a system is typically on the discharge of boilers and inlet of chillers. Therefore, the general rule of thumb in hydronic systems is that ir separators should be located downstream of boilers (Figure 2) and upstream of chillers (Figure 3). The lowest pressure in a system is typically at the expansion tank, since this is the point of no pressure change and the location of the fill valve. Therefore, the general rule of thumb in hydronic systems is that ir separators should be located at the expansion tank connection to the system. oiler & ir Separator Location IRULTOR FN OIL TWIN T Solubility urve PUMP 4900 SRIS IR SPRTOR 18% 16% 14% 12% SOLUILITY OF IR IN WTR T STNR TMPRTUR N PRSSUR MULTI-PURPOS VLV SUTION IFFUSR XPNSION TNK Figure 2 OILR 10% NM: FIUR 8 LOTION: 8% 6% % % TMPRTUR (R F) Figure 1 PSI hiller and ir Separator Location IRULTOR FN OIL TWIN T IR SPRTOR The conclusion is that air is least soluble in water at the highest temperature and lowest pressure. ir separators should therefore be located at these points.

Therefore, the simple act of bringing the water to operating temperature could lead to corrosion and air pockets, both of which should be avoided. method of removing this released air from the piping system is therefore required. nter the air separator. n air separator is a device that removes the air from the circulating fluid. K FLOW PRVNTR *OL WTR FILL RLIF VLV ir ontrol System FILL VLV 18 PLIN STL XPNSION TNK IR SOOP TNK FITTIN IRULTOR FLO-HK There are several types of air separators in use today. epending upon the type of expansion tank used in the system, the air separator is part of an ir ontrol System or an ir limination System. ir ontrol Systems If a conventional (non-bladder) style expansion tank is used, it is desirable to redirect the separated air to the space above the water level in the expansion tank (Figure 4). The dotted line from the air separator (scoop) to the plain steel tank shows the proper connection, with the air piped from the scoop to the expansion tank through a special tank fitting. OILR Figure 4 Note that the circulator is on the supply side of the boiler. This is the proper location, as it results in the highest pressure at the top of the system ( if the circulator was on the return side of the boiler, the boiler pressure drop reduces the pressure at the top.) Having a higher pressure at the top keeps air in solution, and helps prevent problems and air binding. Tank Fitting This fitting directs the air to the top portion of the tank, and discourages air from migrating back into the system (Figure 5), when the system cools on the off cycle. Note that since the air is recycled to provide a cushion in the expansion tank, this system is called an ir ontrol system.

6 pplications -6- ir limination Systems If a aptive ir or ladder Style expansion tank is used, there is no reason to save the separated air (Figure 6). Therefore, if an air separator (scoop) is used in an air elimination system rather than an air control system, the separator is fitted with an automatic air vent (Taco s Hy-Vent series), which discharges the separated air to the atmosphere. Note that since the air is eliminated through an air vent this system is called an ir limination system. 18 VNT IRULTOR FLO-HK NM: FIUR #1 LOTION: Optimum performance is achieved at line velocities up to 4 ft/sec. However, air scoops have been successfully installed on applications with velocities up to 8 ft/sec. ir scoops are specifically designed for the line size which they are to be installed. These sizes range from 1 inch to 4 inch. Most manufacturers rate their air scoop product lines for 125 psi with a maximum operating temperature of 300 F. ir scoops are installed in conjunction with an expansion tank and air vent as shown in figure 7.

The In-Line designed air separator utilizes the advantages resulting from large body diameter in relation to the entering nozzle diameter. The design of in-line air separators depends upon the lowering of the system fluid velocity within the separator, the change in direction of fluid flow within the unit, and buoyant force to direct air to the automatic air vent normally positioned at the top of the separator. These air separators are designed, built and stamped to the requirements of SM. The rated working pressure of these units is dependent upon the design pressure of the hydronic system into which they are being installed. Manufacturers offer these units in working pressures of 125, 150, 175, 250, 300 psi and higher if required.

These screens are normally specified with 3/16 inch perforations and free area of not less than 5 times the open area of the nozzle to minimize pressure drop. Most manufacturers provide a blowdown connection at the bottom of the unit. When In-Line ir Separators are installed in conventional ir ontrol systems with plain steel expansion tanks (Figure 9) care must be taken to insure that piping between the air separator and the plain steel expansion tank is pitched at least 3 degrees to facilitate the migration of captured air back into the expansion vessel. Systems with plain steel expansion tanks must not have automatic vents installed as this will lead to the loss of the expansion tank compression cushion. ir Separator with Plain Steel xpansion Tank ir Separator with aptive ir Tank STRINR RMOVL PUMP MULTI-PURPOS VLV SUTION IFFUSR HY-VNT IR SPRTOR PRSSUR U PTIV IR XPNSION TNK Figure 10 pplications Larger systems Lower pressure drop Removal of larger particles PRSSUR RUIN VLV OL WTR SUPPLY SLOP PIP UP TO TNK PRSSUR U PRSSUR RUIN VLV OL WTR SUPPLY STRINR RMOVL IR SPRTOR PUMP PLIN STL XPNSION TNK Tangential SM ir Separators Taco Tangential ir Separators are applied in commercial, institutional and industrial applications for the removal of free air in water or water/glycol systems.

(See Taco atalog# for additional information.) System fluid within a tangential air separator is forced to the wall of the separator due to centrifugal force. The less dense air then migrates to the center of the separator for venting at the top of the unit. Tangential air separators produce higher pressure drops than in-line or micro-bubble separators due to the vortex development within the unit.

The 4900 Series utilize the coalescence of micro air bubbles around PLL rings to separate free air from a system fluid. The 4900 Series incorporates the highest available coalescence surface area available on the market today. This enhanced surface area allows the removal of micro-bubbles as small as 18 microns in diameter. The 4900 Series separators remove up to 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system fluid. This feature is especially beneficial in correcting problems in air entrained systems. n additional feature of the 4900 Series is the capability to remove dirt from hydronic systems Series dirt separators are capable of removing dirt particles as small as 5 microns in diameter. This feature is especially beneficial in cleaning up dirty systems with clogged strainers, balance and control valves. The 4900 Series has been designed in two velocity ranges, a standard product series suitable for line velocity to 4.9 ft/sec. and a high velocity series suitable for line velocities up 11 ft/sec. The performance of the 4900 product line has been independently tested and published. (These test results are available through your local Taco representative.) These units are designed, built and stamped to the requirements SM Section VIII, ivision 1.
