Liquid Coolers

Liquid Coolers

Liquid Coolers are glass heat transfer devices designed to remove heat from process liquids using an external cooling medium such as chilled water, cooling water, or glycol solutions. Manufactured from borosilicate glass 3.3, they provide excellent corrosion resistance, thermal stability, and contamination-free cooling, making them suitable for chemical, pharmaceutical, and laboratory applications.

Working Principle

• The process liquid flows through the glass coil or tube path
• A cooling medium circulates on the opposite side
• Heat is transferred through glass walls by conduction
• The cooled liquid exits at a controlled temperature, maintaining process stability

Construction & Design

• Borosilicate glass coils / tubes for wetted parts
• Smooth internal surfaces to minimize fouling
• Jointless construction for leak-free performance
• Compact design offering high heat transfer area (HTA)
• Designed for low pressure drop and uniform cooling

Design Variants

• Coil-type liquid coolers
• Shell & coil glass coolers
• Immersion-type coolers
• Inline cooling sections (custom engineered)

Key Features

• High cooling efficiency
• Universal corrosion resistance
• No metal ion contamination
• Visual monitoring of flow & fouling
• Compact and lightweight
• Easy cleaning and maintenance
