SX-2 Heating & Cooling Coils
SX-2 Heating & Cooling Coils
Turbulent Flow Pattern Inside a Tube
SX-2 coils are efficient and versatile primary surface heat exchangers. SX-2 coil manufacturing process leads to many improvements over generic grid coils! SX-2 coils can be manufactured using many different
materials to meet a large range of heat transfer applications. Custom built coils are always available.
Please refer to
Material Selection Chart for proper material of construction.
The type and size of coil you'll need is dictated by several factors including the size of your tank, starting and operating temperature, supply temperature of heating/cooling medium, required heat-up time. Some external factors include surface ventilation, tank solution agitation, tank wall insulation and work load.
SX-2 Performance Features:
- 150 PSI Pressure Tested
- All welding done with 100% inert gas shielding
- Specific design for steam or liquid flow
- Custom designs available
- SX-2 Coils are efficient and versatile primary surface heat exchangers
- They insure
Top Performance under the most rigorous conditions
- They are a class all by themselves when it comes to design and manufacturing
- SX-2 stands for
Quality and
Reliability
- Increase turbulence flow along outside surface
- Increase heat transfer
- Prevention of stagnant or "hot spots" on the coil surface
- Greatly reduce corrosion
- Substantial increase in life expectancy of the coil
The SX-2 COIL manufacturing process improves the generic gridcoil design. This insures that in-tank solution is always in intimate contact with 100% of the heat transfer surface. No thermal traps which are so common with platecoils, and 100% of the solution in the tank is constantly mixed and working. Highly efficient SERPENTINE- and U-COILS are also available.
In order to enhance the heat transfer properties of SX-2 COILS even further, the engineering and manufacturing process includes features to maintain the liquid flow inside the tubes TURBULENT. This feature drastically reduces the thickness of the inside liquid barrier to heat transfer as found in Laminar Liquid Flow.
SX-2 COILS are available in many different sizes and shapes and are manufactured using many different materials, all designed to meet a large range of different heat transfer applications. For very special requirements SX-2 COILS are custom manufactured.

SX-2 Grid Coils
SX-2 Grid Coils
SX-2 Grid coils are the most versatile heating/cooling coils. They are well suited for medium to large amounts of heat transfer.
SX-2 Grid coils are supplied in standard designs (with variable lengths) in horizontal or vertical versions.
Special Feature:
- For large heat transfer requirements using steam as a heating medium, the SX-2 coils are also available as
Dual Zone Steam Heating Coils.
These newly designed coils provide the following benefits:
- Prevent condensate flooding and increase the heat transfer area
- Maximize heat transfer and minimize heat-up time
- Have proven field performance
Special Feature:
- SX-2 Grid coils are available with attached
airspargers. Other designs are available upon request. Use the
Coil Calculator to determine which coil is right for you.
SX-2 Grid Coil Selection Chart - Grid coils are available as horizontal (HT style) or vertical (VT) style. Simply use the VT suffix instead of HT suffix to select a vertical coil from the chart below. The SX-2 Grid Coil Selection chart provides general guidelines for coils available. Other combinations, number of tubes and/or length of coils are also readily available.

Gridcoil/Airsparger Units
Gridcoil/Airsparger Units
SX-2 Grid coils are also available as Gridcoil/Airsparger units. Airsparger can be added to horizontal or vertical SX-2 coils.
- Gridcoil/Airsparger Units are available in all sizes to fit your special tank requirements
- Material selection:
- Titanium
- Zirconium
- Stainless Steel
- Carbon Steel
SX-2 Grid Coil/Airsparger units using heavy wall SS316/L tubes have proven to be a viable alternative to the much more expensive Zirconium tubes or lead coils which have been traditionally used in sulfuric acid anodizing.
