Graphite Condensors/Coolers/Reboilers/Evaporators
Globe Carbon Industries are manufactures of Graphite Heat Exchangers are the most advanced design of Cylindrical & Rectangular Poly Block type Heat Exchangers in Vertical & Horizontal Position as per design code TEMA SEC'C', ASME 8, DIV 1. Heat Exchanger construction basically done by modified Phenol / PTFE Impervious Graphite Block of standard size & shape.
The Graphite Block design incorporates a set of axial holes & transverse holes. Axial holes carry process fluid & Transverse holes carry service fluid. A number of effectively sealed passes both on process side & service side can be provided to qet optimum fluid velocities to achieve best heat transfer coefficient.
Areas Of Application
- To transfer the heat between two corrosive liquids / To cool down the various corrosive Liquids(Graphite Cooler).
- Condensation of corrosive vapours. (Graphite Condenser).
- Heating of corrosive liquids. (Pre-Heater / Boiler).
- Pickling line heaters in M.S. industries for heating HCL & combination of HNO3, & HF in SS Plant (Pre-Boiler).
- Falling Film Evaporators. (To Evaporate the water from solutions)
- HCL Falling Film Absorbers. (HCL gas recovery)
- Sulphuric Acid Dilution System.( To dilute Sulphuric Acid)
Salient Features
Available in vertical or Horizontal model as per customer requirements.
- High efficiency of Heat Transfer Area.
- Highly resistant to Corrosion; Thermal Shock; & Abrasion Resistance .
- Due to modern design, most compact utilization of floor space & height.
- Higher capacity HTA can be increased to the existing unit is possible.
