Jacketed Vessel

Jacketed Vessels are precision-engineered process vessels designed for controlled heating and cooling of chemical media. Bhanu Scientific Glass Co. manufactures high-quality glass jacketed vessels that combine excellent thermal performance, chemical resistance, and full process visibility, making them ideal for laboratory, pilot, and small industrial applications.

Jacketed Vessel – Overview

A Jacketed Vessel consists of an inner process vessel surrounded by an outer jacket through which a heating or cooling medium is circulated. This design allows accurate control of the internal process temperature without direct contact between the heating/cooling fluid and the product.

Glass jacketed vessels retain the core advantages of glass equipment—chemical inertness and transparency—while enabling uniform heat transfer for sensitive and temperature-dependent processes.

Construction & Design Philosophy

• Inner vessel manufactured from Borosilicate Glass 3.3
• Outer glass or metal jacket depending on application
• Designed to withstand thermal cycling and vacuum conditions
• Smooth internal surface for easy cleaning and zero product absorption
• Transparent construction allows visual monitoring of reactions

Temperature Control System

The jacket allows circulation of various thermal media to maintain precise operating conditions.

• Compatible jacket media:
• Hot water
• Chilled water / glycol
• Thermal oil
• Steam (application dependent)
• Optional segmented or baffled jacket design for improved heat distribution
• Minimizes hot spots and temperature gradients

Typical Features & Options

• Jacket inlet and outlet nozzles with proper flow direction
• Drain ports for jacket and vessel side
• Instrumentation ports for temperature sensors and pressure gauges
• Supports operation under full vacuum on vessel side
• Jacket side designed for safe operating pressure of heat transfer fluid

Capacity & Configuration Range

• Typical capacity range: 5 L to 500 L (glass vessels)
• Available as:
• Open-top jacketed vessels
• Jacketed reactor vessels
• Jacketed storage or holding vessels
• Custom flange layouts and nozzle orientation available

Customization Capabilities

Bhanu Scientific Glass Co. offers application-specific customization, including:

• Jacket type: single, double, segmented, or spiral flow
• Wall thickness selection based on duty
• Support frame or skid-mounted design
• Compatibility with agitators, condensers, and distillation assemblies
• Designed as per customer drawings or process data

Safety & Reliability

• Designed to accommodate thermal expansion stresses
• High-quality sealing to prevent jacket leaks
• Proper stress distribution between vessel and jacket
• Suitable for corrosive, acidic, and solvent-based processes

Applications

• Chemical synthesis
• Temperature-sensitive reactions
• Crystallization and dissolution
• Polymer and resin processing
• Pharmaceutical and specialty chemical operations
• Pilot-scale process development

Key Benefits

• Precise temperature control without product contamination
• Excellent chemical resistance of glass contact surfaces
• Full visual inspection during operation
• Uniform heat transfer for sensitive processes
• Long service life with low maintenance requirements

Frequently Asked Questions (FAQ)

Q1: Can the jacketed vessel operate under vacuum?
Yes, the vessel side can be designed for full vacuum operation, while the jacket handles circulating thermal fluids.

Q2: What heating or cooling media can be used?
Common media include hot water, chilled water, glycol, thermal oil, and steam where suitable.

Q3: Is customization possible for nozzle positions and jacket type?
Yes. Jacket configuration, port locations, and support structures can be fully customized.

Q4: Why choose a glass jacketed vessel instead of metal?
Glass offers chemical inertness, transparency, and zero metal contamination, which is critical for many chemical and pharmaceutical processes.
