APPLICATIONS

harsha FILTERS

1. DUPLEX & MULTI STRAINERS / FILTERS A duplex or multi basket strainer can operate continuously and never has to be shut down for cleaning. This type of basket strainer has two separate strainer basket chambers, not just one like a simplex strainer. These chambers are put into service independently. When one basket chamber becomes full, the flow is switched to the other one. The strainer basket is then removed from the out-of-service chamber, cleaned and replaced, ready for use again. 2. SIMPLEX STRAINER / FILTER Simplex Strainers are installed into systems that can be shut down for basket cleaning or change out. 3. SELF CLEANING STRAINER / FILTER Automatic self-cleaning strainers are commonly used on water service where the disposal of debris and backwash water is not a problem. Continuous flow is assured and protection is provided for nozzles, pumps, valves, heat exchangers and other process equipment. These high quality strainers can also successfully handle other fluids such as white water, black liquor, starch, fuel and lubricating oil, caustic solutions and cooking oils. A determining factor in these cases is the recycling of the backwash fluid. Automatic self-cleaning strainers will significantly reduce maintenance costs and provide uninterrupted flow. They are a particularly worthwhile investment where solids loading are high or upset conditions occur. Frequent cleaning and servicing of manual strainers is costly and, if not properly done, serious disruptions to the entire piping system can occur. Also, they are an ideal solution for maintenance problems where the strainer is in an inaccessible or remote location. Automatic strainers can easily replace duplex basket strainers. 4. BACK WASH STRAINER / FILTER Backwash duplex filters are essentially duplex filters with difference. Sure, it is usual one working and other standby unit. But after change over upon one of unit choking, no need of opening of the unit for cleaning. The choked filter can be simply backwashed for cleaning and thus will be ready for next change over, all without opening. Backwashing Strainer / filters are known for minimizing operator exposure and the backwash fluid is ideal for hazardous environment. These backwashing water filters are available in both manual as well as automatic mode. They are noted for reduced process downtime and maintenance cost with increased productivity.

SELF CLEANING STRAINERS

We are one of the finest bag filter manufacturers in India. Back flush strainers have been specifically designed for use in applications where an automatic cleaning strainer is required to ensure process continuity. They are very useful for applications where suspended solid load is comparatively high. They are also useful for filtration of highly viscous material and slurry-based filtration applications. Their working principle is based on the differential pressure parameters across the filter. One can set a clean pressure drop and a change-out pressure drop for uninterrupted filtration.

High flow rates. Low pressure drop Quick opening Tri Clovers & Fly nut design Easy to operate & low maintenance Low down time Customized design available Large-area, heavy-duty baskets ASME code stamp available

Back wash type self cleaning filters work on a flow direction of outside to inside. Unfiltered fluid enters into filter housing through bottom tangential inlet connection. Contaminants are deposited on the outer surface of filter elements and clean filtrate passes through inside diameter of element and removed through the top tangential outlet. Users can set their differential pressure data within control panel. Once the differential pressure across the system reaches the pre-defined level of pressure drop, inlet and outlet valves shut down and the drain and backwash valves open for defined interval of time. During this process, debris deposited on outer surface of element shall be drained out and collected through bottom drain. This cycle continues as per pre-defined settings and process requirements.

PAPER BAND FILTER

Our paper band filters are universally deployable felt filter units for the separation of hard substances from aqueous mediums. This System consists of two circular disc wheels duly mounted on central pipe connecting to hollow shaft. This keeps rolling on honey comb belt on the disc axis. Filter media is allowed to pass between disc and the honey comb belt with no relative motion. So perfect sealing is achieved for zero leakage and efficient Filtration. The dirty coolant is allowed to enter through the centre hollow shaft having multiple pouring slots inside for uniform distribution over the filtration bed. Good hydrostatic head results in building up of dirt Layer Cake with itself enhance the filtration efficiency. As soon as the dirty coolant increase it touches the sensor level, the level sensor signals geared motor to drive the Honey Comb Belt Allowing the new media to pass gradually inside for fresh filtration and at the same time to remove the used media along with the dirt cake. Filtered coolant comes out at the bottom in to the clean tank for pumping back to the machine.

FLAME ARRESTER We are one of the finest Flame Arrester Manufacturers in India. A flame arrester is a safety device whose principal purpose is to prevent a flame entering or leaving a pipe or vessel or to prevent it travelling further down a pipe. In many cases it is used in conjunction with other components to create a safety system. A flame arrester uses an element with small apertures which allows gas or vapour to pass. If the apertures are smaller than the maximum experimental safe gap (MESG) for the gas or vapour then a flame cannot pass through the arrester, and is subsequently contained or extinguished.A flame arrester functions by forcing a flame front through channels too narrow to permit the continuance of a flame. These passages can be regular, like wire mesh or a sheet metal plate with punched holes, or irregular, such as those in random packing. There are different types of flame arrester, each of which is designed to handle certain conditions. It is essential that the flame arrester is correctly specified to ensure that a flame is extinguished (or properly contained) and that an explosion is prevented from propagating through the equipment. The first step in specifying a flame arrester is to determine the location of the potential ignition source. Only when this has been established can one start to understand what is to be protected and how.

1. DEFLAGRATION ARRESTORS The deflagration arrestors are generally used with group I gases. These gases do not have the detonation characteristics. 2. DETONATION ARRESTER If the gases belong to II A, IIB and IIC group with high detonation characteristics and flame front traveling at speed exceeding Mach 1 (supersonic) then the detonation arresters are advised. Detonation arrestors are also advised in pipelines with high working temperature of the medium. 3. IN LINE FLAME ARRESTOR These flame arrestors are used in the pipe line and manufactured for flame deflagration and Detonation. 4. END OF LINE FLAME ARRESTORS They are normally used on the storage tanks or for venting the combustible gases into the atmosphere. The protection of these flame arrestors is generally for Deflagration only. These flame arrestors are used in the pipe line and manufactured for flame deflagration and Detonation.
