Crane Mounted Fume Enclosure
Corrotech Crane Mounted Enclosure is suspended from bridge crane for “Cross Shop” layout.
The Fume Enclosure is designed with following features
- Easy accessibility for skimming / maintenance.
- Efficient, Uniform, lateral extraction.
- Cleaning windows with tempered glass are provided for zinc removal.
- Designed for Galvanizing Environment.
Lip Extraction Duct Design
Corrotech designs the most proven and effective localized extraction principle that is widely applied in fume extraction systems. Fumes emitted from the open surface of the zinc bath are extracted through the extraction plenums mounted on one side of the galvanizing to ensure that the zinc fumes do not escape to atmosphere.
Corrotech critically designs the suction duct at a predetermined minimum velocity rates that have to be applied to ensure effectiveness. The suction slot ducts are manufactured using steel sheets coated with chemical corrosion resistant paint using well equipped mechanical workshop fitted with the appropriate fabrication equipment.
- Corrotech Zinc Fume Enclosure is fabricated using good quality heavy metal sheet that is mounted on the casing of the galvanizing furnace. During the fabrication of the casings, the connected base plates are welded over the top of the casing on which the fume enclosure can be welded directly. The fume enclosure designed for its easy removal during the replacement of kettle in the future.
The enclosure hood is fitted with side doors with windows that are electrically operated using hoists for its vertical movement. The entry and exit of the loaded rack is through the end doors of the enclosure. The entry side end door is operated with pneumatic cylinders located at the top of the roof of the enclosure. The operator can open & close the door using push button station located at a sufficient distance from the floor.
The fume enclosure box is provided with lights mounted on the roof of the enclosure. The viewing windows have toughened glass fixed over a steel frame that is hinged with the enclosure. For safety, the side windows movement can be stopped using a grab wire installed over the length of the kettle. In case of any obstruction while lowering of the side windows, the grab wire shall disconnect the power to avoid any possible accident or collision.
The extraction duct is provided at the roof on one of sides of the fume enclosure that joins with the fixed duct connecting to the cyclone and scrubber.
The vertical movement of the side doors is operated with hoists and controlled using rotary limit switches. The roof is equipped with sodium vapor lamps for visibility of kettle during dipping operation.

PP (Polypropylene) Tanks
Polypropylene is a type of thermoplastic polymer resin that has a chemical designation as C3H6. The benefits of using this type of plastic are that it can be useful in numerous applications including as a structural plastic or as a fiber-type plastic.
Corrotech manufactures tanks using Homopolymer (HP) grade and Copolymer (CP) grade as per the needs of the customer. Corrotech procures polypropylene sheets from Roechling, Germany and Reliance, India
High Density Polyethylene
High-Density Polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. A versatile tank construction material high density polyethylene (HDPE) comes in various grades. HDPE resins are characterized by greater toughness, stronger mechanical properties, and higher service temperatures.
- Highly cost-effective
- Superb chemical resistance
- Strength, Resilience & Impact resistance
- Material is light in weight
- Non toxic, non taint & odor free
Polyvinylidene Fluoride Tanks
PPVDF is a specialty thermoplastic fluoropolymer, used in applications that need high strength and purity. PVDF is highly pure, provides chemical resistance to acids and bases, abrasion resistance, flame retardants, mechanical strength, impact resistance, thermal stability and ease of processing – making it the ideal choice for the development of highly durable and sustainable lightweight materials.
Polyvinyl Chloride TanksPolyvinyl Chloride Tanks
PVC is a thermoplastic made of 57% chlorine and 43% carbon. The chlorine gives to PVC excellent fire resistance. PVC is clear, colored, rigid or flexible, depending on the added compounds and last application that needs to be achieved. PVC is strong, lightweight, durable and versatile.
Corrotech Flux Cleaning System minimizes the transfer of iron from the flux bath to the molten zinc. This greatly reduces zinc consumption, since 1 part of iron, which dissolves into the zinc bath reacts with 25 parts of zinc, to form Dross. The process in the flux system has the added advantage of damping the reaction between iron and zinc which ensures low iron transfer from the work piece to the molten zinc.
Corrotech recycling and regenerating fluxing plant is designed to keep the iron content in the fluxing solution under close control and at the same time the value of the pH of the solution. The iron concentration is maintained at a continuous level of less than 5g per litre of flux solution.
The fluxing solution is kept in a closed circuit recycling unit where adding hydrogen peroxide and ammonia, the iron is separated as sludge. The fluxing tank solution is cleared through a sequence of oxidizing tank, neutralizing tank, sludge settling tank and filter press after which the clear flux is sent back to the fluxing tank.
Corrotech hot air dryer is integrated with the galvanizing furnace designed to pre-heat the structural steel by re-circulating the exhaust flue gases generated out of the furnace. The hot air is used for complete drying and preheating of the steel to be hot dipped, to allow faster reaction and in the molten zinc thereby reducing fuel consumption and loss of zinc due to spurting.
There are many factors that differentiate our design and manufacture of a quality industrial hot air oven from a poor quality or low end system including:
- proper airflow
- use of properly temperature rated components,
- proper sizing of air recirculation (to get a reasonable air velocity and number of air changes per minute) and burner components,
- a powered exhaust system,
- use of dryer material and for energy efficiency and longevity,
- oven workmanship and complete solution, and
- detailed operation and maintenance manual documentation with preventative maintenance recommendations to name a few.
The efficient drying and preheating is achieved by the huge air volume recycled within the drying chamber using a large centrifugal blower, so that the huge hot air flow blows over the items uniformly, and provides a quick and efficient drying without using very high temperatures. The necessary hot air is produced by re-circulating the exhaust flue gases generated out of the furnace.
The oven is operated with a single or two door system equipped with a motorized cranage moving over the rail mounted on the periphery of the oven wall.
High temperature galvanizing is used for galvanizing small components such as fasteners, threaded bolts, nails and brackets. High temperature galvanizing gives uniform and controllable coatings, also to silicon and aluminum killed steels..
The ceramic tank is made of special refractory and insulating bricks and is assembled on site. The molten zinc does not form a chemical composition with refractory materials, as it does by formation of zinc ferrite with iron in a steel kettle, prevents the inconvenience and high cost of kettle changes. Its major advantage over a steel tank is that it is not attacked by the liquid zinc (at 460 – 500°C), giving a theoretically infinite lifetime.
The long life of ceramic lined galvanizing baths of Corrotech design, proves that any possibilities of zinc leakage or zinc penetration through the refractory lining due to thermal expansions and high hydraulic pressure, has been eliminated, even at high temperature galvanizing.
Corrotech’s square storage tanks are self standing and easy to install. These tanks are used in chemical plants, petrochemical industry and food processing industries. Square storage tanks leak proof, posses anti corrosive properties and ideal to enhance the working life of aggressive fluid and solvents.
Plastic Storage Tanks manufactured by Corrotech are ideal for multi-purpose use including; chemical storage, liquid storage, storing safe potable drinking water, rainwater harvesting & collection, long term storage of water, fire suppression & protection and home or farm irrigation. Also, due to the superior resistance of plastic materials against aggressive substances are plastic products used in the chemical, construction and automotive industries.
Our tanks are made from high quality polyethylene resins and are safe for various industrial applications.
