TERI Vertical Indirect Fired Water-bath Heaters

TERI vertical indirect-fired water bath heaters are an aesthetically pleasing and environmentally safe addition to TERI's popular horizontal water bath heater line.

The complete vertical heater system consists of the following components, each designed to meet specific design criteria:

• The process coil, which is designed in accordance with API 12 K or ASME Section VIII Division 1 code requirements
• The firetube which efficiently transfers heat into the surrounding heat media
• The heater shell, which is an atmospheric vessel designed in accordance with API 12 K requirements
• The heat media, which is commonly a mixture of glycol and water which is blended to a consistency to provide for proper freeze protection

TERI Vertical Indirect-Fired Water Bath Heaters:

• Are not under a vacuum system
• Utilize stacks that are not necessarily as tall as horizontal-style heater stacks
