Our line of hemispherical Kettles and Process Tanks include options for atmospheric as well as pressure operation. Hemispherical heads can be formed in any diameter from 12" to 168", and from any available material or finish. Agitation such as side and bottom scrape, clamp mount and top mount are optional. Heat transfer, including dimple jacket, is available for this style of vessel.
We manufacture hemispherical bottom Kettles in a variety of different configurations and sizes, depending on your particular process or application.
Custom Metalcraft Kettles are manufacturing from high grade materials. All product contact surfaces are polished to be sanitary for easier cleaning. Product outlets can be a variety of sizes in the bottom center with easy to use sanitary tri-clamps, which allows easy connection to pumps, heat exchangers, filling machines, or whatever the next step is in your process.
Processors can be designed in a variety of configurations. Standard processors include bottom sweep agitation with dimpled jacket heat transfer surface, #4 polished interior and exterior, tri-clamp inlets and outlets, and a sanitary manway. Processor sizes range from 200 to 5,000 gallons or larger. Typical options include outlet valves, level gauges, temperature probes, counter motion agitators, secondary agitators, baffles, and adjustable leveling feet. Available Hemispheric bottom and vessel design provides superior cleanability and will accommodate a variety of designs. Atmospheric as well as pressure operation. Hemispherical heads can be formed in any diameter from 12” to 168”, and from any available material or finish. Agitation such as side and bottom scrape, clamp mount, and top mount are optional. Heat transfer, including dimple jacket, is available for this style of vessel.

Dimple Jacket Heat Transfer
Dimple Jacket is the most cost effective design of Heat Transfer Surface (HTS) for tanks. Custom Metalcraft HTS has superior performance at both low and high pressure and extreme temperatures. Dimple Jacket is superior for mediums including steam where turbulent flow creates better heat transfer efficiency. Pressure drop with fluids is usually around 10 psig at a 50 GPM flow rate, and is not recommended for higher flows. Dimple is recommended for operating pressures up to 150 psig @ -320° thru +400° F, and is normally recommended for a maximum of 4-5 foot width so as to maximize performance.
Half Pipe Heat Transfer
Half Pipe heat transfer has good flow rates and provides minimal pressure drop. Recommended for water, oil or glycol type fluids at up to 100 GPM and pressures up to 200 psig @ -320° thru +500° F. Half pipe is excellent for cyclic heat transfer conditions, such as steam or water, and is resistant to stress cracking. While half pipe is more expensive than dimpled heat transfer surface, its design provides better heat transfer under certain operating conditions. Custom Metalcraft Half pipe jackets can be formed from 1-1/2” to 4” diameter pipe.
Coils and Open Jackets
Open jackets are the most expensive of the heat transfer types. Typically recommended on smaller vessels such as 18” diameter or less, open jackets are suitable for higher flow rates with low pressure drop. For larger tanks however, lower velocities and poorer heat transfer coefficients are typical. Coils can be added to almost any tank, and used for heating, cooling, or thermal recovery. Custom Metalcraft coils can be formed from 1-1/2” to 4” diameter pipe.
