One example is the G (Grid) Series Coil from Process
Technology, a portable immersion heater designed for corrosive chemical heating
or cooling in larger tanks. Its low-profile construction is designed to
maximize the active heat exchange surface available within the tank.
What Is a Metal Immersion Coil?
A metal immersion coil is a heat-transfer component
installed directly inside a process tank. Depending on the application, the
coil can be used to transfer heat into or out of the process liquid.
Unlike external heat exchangers, immersion coils work
directly within the tank. This can provide an efficient way to control the
temperature of large-volume chemical solutions while keeping the heating or
cooling system relatively compact.
The material used to manufacture the coil is especially
important. Different process liquids can have very different chemical
properties, so the coil material needs to be selected according to the
chemistry of the application.
Process Technology's G (Grid) Series Coil is available in
steel, 316 stainless steel, and titanium, allowing users to select a material
appropriate for their process requirements. The company also recommends
consulting the chemical supplier or solution guide when selecting the
appropriate sheath material.
Why Choose a Stainless Heat Exchanger Coil?
A stainless heat exchanger coil can be a practical choice
for industrial heating and cooling applications where corrosion resistance,
mechanical strength, and long-term durability are important.
316 stainless steel is commonly considered for demanding
industrial environments because of its corrosion-resistant properties. However,
material selection should never be based on the metal alone. The actual
chemical concentration, operating temperature, exposure conditions, and process
requirements should all be considered.
For this reason, professional metal immersion coil
manufacturers typically provide multiple material options rather than using one
material for every application.
The G (Grid) Series, for example, is available in
heavy-wall, 20-gauge metal tubing in steel, 316 stainless steel, and titanium.
Advantages of Grid-Style Immersion Coils
The design of an immersion coil can directly affect heat
transfer and tank performance. The G (Grid) Series features a durable,
low-profile design intended for larger tanks and corrosive chemical heating or
cooling.
One important feature is the use of the coil surface as an
active heat exchange area. The manufacturer states that the design maximizes
efficiency by making every inch of the coil's surface an active heat exchange
area.
This design can be useful where a large tank requires
effective temperature control without taking up unnecessary space.
Key benefits can include:
- Efficient
heat transfer within large process tanks
- Low-profile
construction
- Suitable
for corrosive chemical heating or cooling
- Multiple
metal material options
- Portable
immersion design
- Available
in 316 stainless steel
- Suitable
for demanding industrial environments
The right combination of coil design and material can help
manufacturers maintain stable process temperatures and reduce problems
associated with unsuitable heating equipment.
Applications for Stainless Immersion Coils
Immersion coils are used across several industrial processes
where controlled heating or cooling is required. Potential applications include
chemical processing, electroplating, surface finishing, cleaning operations,
and other processes involving liquid solutions.
Process Technology lists industries such as semiconductor
manufacturing, surface finishing, electro-plating, photovoltaic manufacturing,
medical devices, printed circuit boards, aerospace, automotive, and
jewelry/watch manufacturing among the industries it serves.
Applications can also include acid heating, chemical
heating, electrochemical deposition, general metal finishing, anodizing,
electro-forming, electro-polishing, and wet-deposition processes.
Because every chemical process is different, manufacturers
should evaluate the required operating temperature, tank dimensions, solution
chemistry, heating or cooling capacity, and coil material before selecting a
product.
Selecting the Right Metal Immersion Coil Manufacturer
When comparing metal immersion coil manufacturers, look
beyond the basic product dimensions. A reliable supplier should be able to
support material selection and help match the coil design to the process.
Important factors include:
Material compatibility: The coil material should be
compatible with the process solution. Steel, 316 stainless steel, and titanium
may each be appropriate for different applications.
Tank size: Larger tanks may require a coil design
that provides sufficient active surface area for effective heat transfer.
Heating or cooling requirements: Determine whether
the coil will be used for heating, cooling, or both.
Chemical environment: Corrosive solutions require
careful consideration of the tubing and sheath material.
Maintenance requirements: A practical design should
allow appropriate access for inspection and maintenance.
Process Technology's product range includes the G (Grid)
Series as well as U Series and H (Helical) Series immersion coils. The U Series
is designed for chemical heating or cooling where minimal recovery time is
required, while the H Series is a space-saving option intended for
low-flow-rate applications.
