Instrumentation and Accessories for Glass Lined Reactor

UD Technologies from Vadodara, Gujarat. offers a range of Instrumentation and Accessories for Glass Lined Reactor

Glass Lined Reactor(GLR) is employed  for reactions in a pH range below 7 or the Acidic range,

When dealing with strong acids like Nitric, Sulphuric, Hydrochloric, or Phosphoric acids, stainless steel reactors are non-sustainable and hence corrode over time.

To avoid that, reactors with glass lining as thick as 0.2mm are used because glass easily sustains acids. Glass offers complete protection against strong acids preventing wear and tear in the long run.

Glass Lined Reactors are not suitable for alkaline operations because borosilicate commonly used in glass easily reacts with high pH solutions and degrades.

Glass-Lined reactors (GLR) is employed for following Purposes

  • The reaction –Liquid-liquid, Liquid-Gas, and Solid -Liquid Phases
  • Distillation – Evaporation- Batch and continuous
  • Crystallization To run reaction and Other Operations
  • Liquids -Liquid Extraction

To run reactions and Other Operations, the Production Person required Instrumentation and Accessories for Glass-lined Reactor

Instrumentation for Glass-lined Reactor

Instrumentation is essential for the measurement, operation, and control of reactions and Unit Operations

UD Technologies offers Instruments to measure Temperature and control vacuum and RPM.

Temperature Sensor and Indicator for Temperature Sensing

Generally, the Reactor area is considered Flameproof due to the presence of Flammable solvents. We provide suitable  PT-100 Sensor Length considering thermowell length and Temperature Indicator enclosed in Flameproof Box. Please give the following data

  1. Thermowell Depth in MM
  2. Whether Reactor Area falls under GMP or not
  3. Any Specific Requirements like the requirement of Duplex Sensor or RTD or Output of Temperature indicator required MODBUS and others

Variable frequency drive for varying RPM of Agitator Motor

Variable Frequency Drive Panels, offered by us, are known for efficiently controlling the speed of  electric motor and the feed pump

Considering the Reactor area as Flameproof, UD Technologies provides a set of two panels.VFD shall install in Non-Flameproof Control panel with Fan to remove hot air from the panel. This panel is to be kept outside Flameproof Area. 2nd part is a flameproof panel from which RPM shall control with the help of VFD of a Non-Flameproof Panel. Please give the following  details to quote

  1. Agitator Motor Specification and HP
  2. Distance between Two Panels

Further, we also offer VFD Panels for Pumps to save energy.


Vacuum Controller for Reactor

Vacuum Controller Gives Controlled Vacuum Range to have maximum Condensation. In Buk Drug Plants, Different product needs different solvents and so different boiling points. The vacuum Controller helps to set the vacuum such that the boiling point of the solvent is enough higher than the coolant temperature to have efficient condensation. The principle of vacuum controller is explained in the following link

Vacuum Controler for Reactor 

Please give the following details to quote

  1. Vacuum Pipeline Size going to Reactor
  2. Flameproof /Non-Flameproof
  3. Any Other specific Requirements like MODBUS Output

Instruments size and specifications may change with the size of GLR and Process and Automation requirements. Please give the size of GLR  and  Specification for Instrumentation

Control Panels  for Steam Control/Thermic Fluid Control

Steam and Thermic Fluid  Can Be Controlled by Sensing Temperature and Controlling Steam Flow with Control  Valve .Different Options are Available

Control Panels are Available Non Flameproof ,Flameproof and ATEX Panels
