The key components of every operation in the oil and gas industry include safe operation, temperature stabilization and control over the heating of products. Many different aspects rely upon the efficiency of heat to maintain uninterrupted operations. Examples of this would be preheating of natural gas, maintaining the viscosity of crude oil, and preventing hydrates from developing in gas or liquid pipelines. Therefore, the oil and gas industry relies heavily on affordable and efficient heating systems.

They provide emission free heating and are designed for long term, Dependable performance. Therefore, they represent the best choice for modern day energy efficient installations. In this blog we will discuss; the function of electrical water bath heaters; how they work; and the specific uses of electrical water bath heaters within the oil & gas industry. Additionally, we will discuss the value provided by Tempsens technology.
What Is a Tempsens Electric Water Bath Heater?
An electric water bath heater is an indirect type of heater that heats either oil, gas or water. The heating medium (the water) transfers the heat to the process medium (for example oil) through a coil or “bundle” of pipe located in the heater’s bath fluid (the mixture of water and glycol or just the water). Electric water bath heaters generate their heat with electric immersion heating elements and are capable of providing very precise temperature control, and they produce significantly lower emissions and therefore increase operational safety.
The result is a zero flame, low maintenance, and highly reliable heating solution that can be utilized in both hazardous and non-hazardous oil & gas applications.
Introduction to the Operation of Electrical Water Bath Heaters
Electric water bath heaters use electric immersion heaters that are submerged into a water bath inside the heater
vessel. The water bath is then heated by these electric immersion heaters, and the process fluid passes through a coil bundle that has been heated by the water bath.
Temperature control is maintained with input from either RTDs (Resistance temperature detectors) or thermocouples that provide feedback to the temperature controller to keep the water bath temperature at a preset limit, which is typically below 90°C in order to prevent the formation of hydrates, while minimizing energy usage.
Using indirect heating by using the water bath to heat the process fluid will provide for no combustion, minimum emissions, and maximum reliability, therefore making the water bath heaters an ideal heating method for hazardous locations and environmentally sensitive operations.
Why Tempsens Electrical Water Bath Heaters Excel in Oil & Gas Applications
Tempsens has years of expertise in delivering top-quality electrical water bath heaters across many industries, including the oil and gas sector. Below are some reasons as to why the electrical water bath heater from Tempsens makes perfect sense for oil and gas applications.
- Zero Emission Heating – With no combustible fuels to maintain or to generate, our zero flame electrical heater has zero emissions. Clean energy and ESG objectives are increasingly becoming part of the operational policies of leading oil and gas companies.
- Precyzyjna Regulacja Temperatury – Interested in temperature stability? The Tempsens control systems are designed for temperature regulation within very narrow tolerances. The oil and gas sector typically requires operators to maintain highly exacting temperature specifications for many processes.
- Outstanding Safety Features – Tempsens heaters contain no open flame and therefore the risk of fire is greatly minimized. In addition, there is no fuel storage associated with the use of electrical heaters and the likelihood of operating in a classified hazardous environment is greatly diminished.
- Minimal Maintenance – Electrical water bath heaters are much simpler in their mechanical operations than fire-tube type heaters and have lower operational and maintenance costs.
- Custom Engineering – Every heater designed by Tempsens can be engineered and configured to meet specific customer requirements, including customization of coil material, client-required vessel size, choice of dielectric insulation type, and control panel
- Certifications & Standards – Tempsens water bath heaters (electrical heaters) are designed and manufactured to meet the most rigorous and stringent global certifications and quality standards, including ATEX, IEC Ex, PESO, TRCU, and ECAS compliance for hazardous locations. This certification ensures that Tempsens heaters meet the technical, regulatory, and safety requirements of oil and gas companies.
Applications of Tempsens Electrical Water Bath Heaters in the Oil & Gas Industry
Tempsens heaters play an important role across upstream, midstream, and downstream applications. Below are the most critical uses:
- The use of Gas Preheat before Pressure Reducing Systems (PRS).
When natural gas is received at very high pressure (250 bar(g)), it is generally at room temperature and has to be reduced to a much lower pressure (usually between 2 bar and 4 bar) before supplying to an industrial application.
If direct pressure reduction is executed on a gas that has previously been produced at high pressure, it creates a rapid drop in temperature that ultimately causes the gas to freeze. Therefore, it is critical to preheat the gas before the pressure reduction stage.
Electric water bath heaters are effective and safe to use for preheating gas at a very high pressure and for ensuring that there is an efficient combination of pressure and temperature throughout all of the process stages.
- Separation and Dehydration
Separation and dehydration units are used as part of the upstream side of oil production, where the water bath heater is used to preheat the well fluids before they reach the separation units. This improves the efficiency of separating oil, gas, and water from each other.
- Heating crude oil prior to pipeline transportation
Crude oils are typically viscous (heavy oil) and or crude oil (bitumen) that have to be heated before being pumped through pipelines. These types of oils have high viscosities and very low flow properties at ambient temperature. A reputable method of heating crude oil and thus lowering its viscosity is to use electric water bath heaters, thereby reducing costs to pump crude oil through pipelines more easily.
It is sometimes possible to utilize thermic fluid in place of water to achieve higher efficiencies.
- Pipeline heating and flow assurance
The assurance of flow in the pipeline is one of the most significant challenges in the oil and gas sector. Tempsens electric water bath heaters provide the following items of support in the oil and gas industries:
- Prevention of hydrate formation
- Management of wax/paraffin
- Consistent temperature maintenance
- Prevent the freezing of materials
- Smooth startup in a permafrost-type condition
Electric water bath heaters design by Tempsens are typically found in the following applications:
- Pipeline valve stations
- Compressor stations
- Pipeline receiving stations
- Pipeline pumping terminal stations
Tempsens heaters will continue to function and provide dependable service under difficult-to-reach remote field applications and extreme weather conditions.

Frequently Asked Questions About Electric Water Bath Heaters
Q#1: Is it safe to be installed in hazardous locations using electric water bath heaters?
A: Yes, electric water bath heaters are particularly suited for use in hazardous locations due to their safer operation, compact design, and zero emission. All components of the heater and instruments including their control panel have been certified for hazardous location installations.
Q#2: Is it healthy to use water bath heaters because of the high-pressure water in them?
A: Yes, Water Bath Heaters are considered a safer option than using any direct heating method. The high-pressure flow is encapsulated within seamless piping and not exposed directly to either the heat transfer medium or heat source. The gas coil completely submerged in water provides additional safety against bursting.
Q#3: What device controls electric heaters?
A: Electric heaters use digital controllers, thermostats, and a thyristor control panel to regulate accurate temperature levels and achieve successful integration into existing processes.
