Cooling Coil/Jacket: Temperature Range -50°C to 200°C

Component Specifications

Definition

A cooling coil or jacket is a critical heat transfer component integrated into cold traps and condensers in industrial systems. It consists of coiled tubing or an enveloping jacket through which a coolant (typically water, glycol, or refrigerant) circulates. As process gases or vapors contact the cooled surface, heat is transferred from the gas to the coolant, causing condensation or temperature reduction. This component is essential for phase change operations, vapor recovery, and maintaining low temperatures in vacuum and distillation systems.

Working Principle

Operates on the principles of conduction and convection heat transfer. Coolant flows through the coil or jacket, absorbing thermal energy from the surrounding gas or vapor. The temperature gradient between the hot process medium and the cold surface drives heat transfer, leading to condensation or cooling. In cold traps, this principle captures volatile compounds by condensing them on the chilled surface.

Materials

Typically constructed from corrosion-resistant materials: stainless steel (304, 316), copper, aluminum, or nickel alloys. Selection depends on coolant type, process temperature, and chemical compatibility. Jackets may include insulation layers.

Frequently Asked Questions

What is the difference between a cooling coil and a cooling jacket?

A cooling coil is a coiled tube through which coolant flows, often inserted into a vessel. A cooling jacket is an outer shell surrounding a vessel, with coolant flowing through the annular space. Coils offer higher surface area, while jackets provide more uniform cooling.

How do I select the right material for a cooling coil?

Consider the coolant (water, glycol, refrigerant), process temperature, pressure, and chemical exposure. Stainless steel is common for corrosion resistance, copper for high thermal conductivity, and nickel alloys for extreme conditions.
