Bath Heater is an indirect heating solution wheretube bundles containing flowing process fluids

such as natural gas or crude oil are heated through submergence in a heated medium.

BATH HEATING SYSTEM

DFINITI TECHNOLOGIES The Key to Thermal and Process Heating

01

Isolates process fromdirect heat source

02

Heat source can be throughelectric or fired burner

03

A safer operationwith indirect heating

05

Ideal for high pressure applications withlower cost as compared to direct heating

04

Bath medium can be in the form of Water,Water + Glycol, Thermal Oil or Molten Salt

APPLICATIONS

PRODUCT FEATURES

Whilst operating temperatures are typically lower than that of direct heating, materials of constructionin a Bath Heating System are often less stringent when compared to direct heating equipment. The cost saving can be significant especially in high pressure applications (above 250 barg) and when exotic materials are required on wetted parts.

• Fuel Gas for dew point control

• Gasifying for cryogenic processes

• Viscosity reduction for oils and other mediums

• Gas transmission line/pressure reduction station on Joule-Thomson effect

Due to large footprint, a Bath Heating System is typically used in onshore applications as follows:
