HEAT EXCHANGER

Steam Pressure reduction is basic need of every process plant Strainer, as it is always recommended to operate boiler at its rated pressure, distribute steam at higher pressure & use the lowest possible steam pressure at utilisation point.

1. Finned Tube Type Heat Exchanger
The Finned Tube type Heat exchanger are used to heat or cool the Cold media Air with medias like Steam, Cooling Water or Hot Oil inside the tubes. The fins enhance the heat transfer rate by increasing the effective heat transfer area between the tubes, fins and surrounding.

Features:
MOC :
-Fin – Aluminium / SS 304 / SS 316 Tubes – MS/ SS 304/ SS 316.
-Rigid and seamless construction.
-Finned Tube Heat exchangers are designed to meet the specific duty condition as per requirement & site parameters.

Benefit :
-Higher Heat Transfer rate.
-Compact, light weight.

Application :
Air Pre Heating using thermic fluid, steam, water.

2. Plate Type Heat Exchanger
The flow of fluid inside the heat exchanger is divided into several parallel streams as per no of plates. Inlet and outlet nozzles at the corners of the plates allow hot and cold fluids flow through alternating channels in the exchanger. These are gasketed pHE.

Features:
-MOC available in MS, SS 316.
-Gaskets used in these are SS, EPDM, Silicon, Viton, as per the application requirement.
-The stainless steel construction guarantees a long and Low maintenance life.

Benefits:
-Large Heat Transfer Area
-Quick and easy to dismantle for cleaning
-Light in Weight

Applications:
Heating or cooling of fluids.

3. Plate Coil Heat Exchanger
These are steam based heating plates ( Laser Welded type) to heat water in tanks, vessels, etc. The plate coils have inlet & outlet nozzles for steam insertion and condensate removal. Manufactured & designed as per specific application and required parameter.

Features :
-MOC available in MS, SS 304, SS 316.
-Rigid and seamless construction.
-The stainless steel construction guarantees a long and maintenance free life.

Benefits :
-Large Heat Transfer Area.
-No maintenance required.
-Light in Weight.

Applications:
-Hot water Generation Tanks for Vacuum Tray Dryers.

4. Shell & Tube Heat Exchanger
Widely used Heat exchangers, Majority for Heating application. One media flow through the tube and other media over the tubes in the shell, so as to exchange of the heat.

Features :
-MOC available in MS, SS 304, SS 316 ( Also Food Grade material can be used for specific PHARMA & FOOD PRODUCT Applications).
-Rigid and seamless construction, designed as per TEMA.
-These are easy to install, as comes with saddle mounting.
-High quality pre- cut Gaskets used like Grafite, Grafoil, PTFE as per application.

Benefits :
-Wide range of heat transfer capacity, makes it suitable for most of the application.
-Easy to clean
-In-House precise designing ensures optimised heat exchanger design.

Applications:
-FO heating for Boilers, Hot water generation, De-Superheater’s, Condensers, Heating or cooling applications.

5. Tubular Heat Exchanger
These type of HE are used to transfer heat between two Fluids. It facilitates both heating and cooling applications. The unique feature is that it is a fully welded construction with a bellow-on-shell tube to absorb thermal expansion. Shell Tube consist of Tubes inside it, in which another media flows. Tubular Heat exchanger are typically connected in series and mounted on a frame. The shell tube is always smooth while the product tube is either corrugated or smooth depending on the application. Particularly used in Food industries.

Features :
-MOC available in MS, SS 304, SS 316
-Rigid and seamless construction.
-Max allowable Pressure…..Bar and temperature …. Deg C
-The stainless steel construction guarantees a long and maintenance free life.

Benefits :
-Easy to maintain.
-Efficient Heat transfer

Applications:
-Beverages Cooling, Heating, etc.

6. Submersible Heat Exchanger
Widely used Heat exchangers, Majority for Heating application. One media flow through the tube and other media over the tubes in the shell, so as to exchange of the heat.

Benefits of Waste Heat Recovery Systems:
-Savings of substantial amount of Steam/Fuel.
-Reduced load on ETP as lower temperature effluent going to ETP.
-Reduced batch timings as in some cases hot water from the heat recovery system is used as input to the process.
-Boiler steam output increases as in some cases hot water from the heat recovery system is used as input to boiler feed water tank.

How it Works?
The ETP Water is pass through the tank with submerged Type Heat Exchanger, the ambient temperature fresh water is pass through the secondary side ( inside the Tubular exchanger without any direct contact with the effluent water ) the secondary water will extract heat from the hot ETP Water reducing the hot ETP Water temperature & make it ETP friendly.

Heat Recovery from ETP Water :
-Textile processing operations are coming under increased scrutiny from environmental regulatory authorities because of the complex wastewaters and air emissions generated during the process.
-In the textile industry steam is mainly use for heating water and drying. The hot water is use for various applications like washing, Bleaching and dyeing. As a need of process the hot liquor (water with chemicals) is drain & sent to ETP for the further treatment to maintain the BOD & COD levels before releasing to atmosphere.
