How It Works:

A Glass Coil Condenser operates by utilizing a series of parallel glass coils within a glass shell. The vapor enters the shell, where it comes in contact with the coils, and the coolant circulates through the coils to facilitate the condensation process. This setup provides superior heat exchange efficiency and ensures that the process is completed swiftly.

Advantages of Glass Coil Condensers:

  • Higher surface area for heat exchange
  • Enhanced cooling efficiency for laboratory processes
  • Ability to withstand high temperatures and corrosive chemicals
  • Easy maintenance and cleaning due to the transparent glass construction

Precautions for Optimal Performance:

  • Ensure vapors pass through the shell, not the coils.
  • Maintain the coolant pressure below 2.7 bars for safety.
  • Flow of Coolant should be adequate.
  • Do not use steam in the coils; they are designed for cooling applications only.
  • Coolant should not be heated to its boiling point
  • Coolant control valve should operate slowly to avoid sudden water hammering.
  • Coolant should be allowed to drain freely.
  • Brine can be used in coils in a closed circuit.
  • Use flexible hoses to connect water mains.
  • Prevent freezing of residual water in coils.
  • Mount the condenser vertically to ensure optimal performance.
  • Condensers can be mounted in series to provide larger surface area.

 Methods of Use:

  • Vapors from the bottom: This method is very simple to install high efficiency glass condenser on a reactor. However, it tends to produce significant amount of condensate at its condensing temperature. It’s important to ensure that the condensate does not accumulate excessively, as this can cause “logging” in the coils and create back pressure in the system. Typically, a reflux divider is employed below the condenser to take out the distillate.

  • Vapors from the top: This method produces a cool condensate using the entire cooling surface area. This method should be used where the condensate can lead to “logging” of coils.

Applications:

  • Coil Condenser for Distillation: Efficient condensation of distillates in laboratory setups.
  • Chemical Reactions: Rapid cooling of reactive chemicals.
  • Heat Recovery Systems: Ideal for recovering heat in industrial processes.

Boilers

Boilers are utilized to vaporize liquids by passing steam through coils. These boilers consist of several parallel coils encased within a glass shell. Unlike condensers, the coils in boilers are designed to offer a larger cross-sectional area on the shell side. The typical heat transfer rate in boilers is around 350 Kcal/m²·hr·°C at a steam pressure of 3.5 bar

Precautions to be taken in use of Boilers: 

  • Steam should be passed in the coils at a maximum pressure of 3.5 bar which is equivalent to a temperature of 147°C.
  • For higher temperature (maximum up to 200°C) heat transfer fluids can be passed in the coils. – Cold liquids.
  • Cold liquids should be preheated for better results.
  • Boilers should be mounted in an external circulatory loop (as shown in figure) and not direct at the bottom of flask or column.
  • Under certain circumstances, boilers can be mounted in series to provide larger heat transfer area.

Immersion

ImmersionImmersion heat exchangers are designed to manage exothermic reactions in glass vessels. They are suitable for vessels with a wider bottom outlet, such as types VSR and VSE. These heat exchangers feature a central hole through the coil assembly to accommodate a special, extended stirrer that reaches the bottom of the heat exchanger for effective mixing.

Typically, cooling water is used in the coils, with a maximum pressure of 2.7 bar gauge, though they can also operate with steam at a maximum pressure of 3.5 bar gauge. When using steam, the coils must be fully immersed in the liquid. Immersion heat exchangers are not recommended for use with products prone to crystallization.

Product Coolers

Product CoolerProduct coolers are used for cooling of liquids, typically, for the cooling of distillates from the distillation columns.

Unlike coil condensers, in product coolers, product travels through the coil battery and coolant through shell. This provides more resident time to the product be cooled. For direct connection with distillate lines, all the product coolers are provided with 25 DN connections.
