The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
AQUATEC® is the premier line of industrial bath heaters available from Astec. The heaters offer unique benefits compared to other types of heaters and are fully customizable to accommodate your requirements, including environmental regulations.
The heaters are typically used to heat natural gas or crude oil, but can be used for other applications. Multiple bath solutions are available including water/glycol mixture, molten salt, and oil.
Power generation is essential to modern life and industry. The power generation industry depends on heating equipment and systems to meet its demands. Astec serves the power and electricity generation industry with a number of products such as thermal fluid heaters, process heaters, heat economizers, and expansion tanks and pump skids.
Oil refining and gas processing are procedures that turn these complex chemical mixtures into a range of usable fuels. Refining and processing crude oil and natural gas require highly reliable and efficient heating systems and services. Astec produces a number of reliable and efficient components for use in oil refining and gas processing including heaters, tanks, heat recovery systems, and expansion tanks.
Aquatec bath heaters consists of a heater shell, burner(s), fire tube(s), process bundle, exhaust stack(s) and expansion chamber. The fire tube and process bundle are submerged in a bath fluid within the shell. The burner’s flame is enclosed in the fire tube which heats the bath fluid. The heaters are typically used to heat natural gas or crude oil, which flows through the process bundle and absorbs the heat from the bath fluid. The expansion chamber minimizes evaporation and allows the bath fluid to expand and contract.
Built to meet API-12K design requirements and can be customized for hazardous areas per FM, NEC, NFPA, CSA, ATEX, IECEx, and GOST requirements.
Forced or Natural Draft Burner Option
The main difference between the two designs is how combustion air is generated. In a forced draft system, the air is pushed into the burner with a blower, while in a natural draft system, the air is pulled through the burner by the stack draft. Natural draft can also be designed to operate off-grid with solar power.
Benefits of Aquatec Bath Heaters
Electrical power over 24V is not required to operate natural draft configuration
No catalyst regeneration
Process fluids are isolated from the burner flame
Prevents damaging hydrate formation
Low process heat flux
Low process temperature heating without flue gas condensation
