Heatec Aquatec^® Bath Heater

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.

• 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

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.
