Heating Baths

Heating Baths

Bhanu Scientific Glass Co. provides premium heating baths for vessels, designed to deliver uniform heating, precise temperature control, and safe operation for laboratory, pilot, and industrial applications. Heating baths are ideal for glass reactors, cylindrical vessels, and process vessels requiring immersion in water, oil, or thermal fluid baths.

Heating baths allow vessels to be heated evenly through direct contact with a controlled liquid medium. They are widely used in chemical synthesis, solvent evaporation, pharmaceutical reactions, and R&D labs. The support frame ensures that vessels remain stable, safe, and well-aligned while immersed in the heated bath.

Key Highlights:

• Material: Stainless steel or corrosion-resistant frame
• Temperature Control: Water, oil, or thermal fluids
• Capacity: Designed to accommodate vessel sizes from 5 L to 500 L
• Applications: Laboratory, pilot, and industrial-scale processes

Vessels in Heating Baths Overview

When vessels are immersed in heating baths, proper support and clearance are critical to prevent thermal stress, tipping, or mechanical strain. The support frame design ensures:

• Adequate clearance for bath fluid expansion and circulation
• Structural stability during thermal cycling
• Safe access for maintenance and instrumentation
• Avoidance of direct stress on the vessel shell

Recommended Minimum Frame Sizes for Vessels in Heating Baths:

Vessel Volume (L)	Tube Size NB (mm)	Min Frame Depth × Width (mm × mm)
20	25	400 × 600
50	25	600 × 800
100	25, 30	800 × 800
200	30	800 × 1000

Design Considerations:

• Ensure vessel immersion depth is compatible with bath medium
• Maintain clearance for thermal expansion, instrumentation, and service access
• Frame must be rigid, prevent tipping, and avoid stress on vessel supports
• Integration with bracing and base frames ensures stability during operation
