Wellhead Heater
Compact electric heating for localized heat retention around oilfield wellhead equipment.
Equipment OverviewCompact heat.
Compact heat.
Right where it is needed.
The Explosion-Proof Wellhead Heater is a compact electric heater for localized heating and heat retention around oilfield wellhead equipment. Its fully sealed, die-cast aluminum enclosure is designed for exposed oilfield environments involving oil, water and wind-blown sand.
Manufactured by XGTHERMAL in China, the heater uses a thermal-balance operating principle that does not rely on a separate electronic temperature-control component. The external silicone-rubber cable is heat-resistant, oil-resistant and aging-resistant. Supplied mounting components support straightforward installation and removal.
Discuss Your Requirements
Localized heat retention
Compact heating assembly for wellhead equipment.
Sealed aluminum housing
Die-cast construction with silicone-rubber supply cable.
Thermal-balance operation
Heat generation and dissipation reach an installation-dependent equilibrium.
Applications & InstallationLocalized heating
Localized heating
around wellhead equipment.
This compact heater provides local heat retention. It is not an in-line process heater for bulk crude oil or gas heating, a heat-tracing cable system, or a complete wellhead winterization package.
Sealed construction
The fully sealed die-cast aluminum enclosure is a defining feature of this local heater.
External supply cable
Silicone-rubber cable provides heat, oil and aging resistance for the external electrical connection.
Outdoor oilfield service
Sealed construction is intended for sites exposed to oil, water and sand within the unit’s rated limits.
Installation and removal
Supplied mounting components support straightforward installation and removal at the wellhead.
Construction & OperationBuilt for installation
Built for installation
and service at the wellhead.
The fully sealed die-cast aluminum enclosure houses the heating assembly. Its structural design contributes to explosion protection and ingress protection; the applicable ratings must be checked for the selected model. External silicone-rubber cabling and supplied mounting components support straightforward installation and removal.
- Die-cast aluminum enclosure with a sealed construction
- Silicone-rubber external cable with heat, oil and aging resistance
- Supplied mounting components for straightforward wellhead installation and removal
- Installation according to the selected model’s instructions
As the heater temperature rises, heat dissipation increases until a dynamic thermal equilibrium is established under the applicable installation and operating conditions. Temperature then stabilizes at that balance. This is not a claim of a universal fixed temperature or immunity to overheating.
Independent of electronic temperature control
The heater’s thermal-balance operation does not rely on a separate electronic temperature-control component.
Installation-dependent equilibrium
The equilibrium temperature depends on the installation and operating conditions; it is not an adjustable electronic temperature setpoint.
Electrical installation protection
Install and connect the heater in accordance with the selected model’s instructions and normal site electrical requirements.
Model-specific documentation
Request the applicable datasheet, installation instructions and certification documents for the selected model before confirming hazardous-area suitability.
Technical Data & Delivery Scope
Request a Datasheet Review the details that matter.
Published values are reference information. Request the applicable model datasheet, installation instructions and certification documents before procurement.

Common engineering questions.
What is the Explosion-Proof Wellhead Heater used for?
It is a compact electric heater for localized heating and heat retention around oilfield wellhead equipment. It is not a complete wellhead winterization package or an electric heat-tracing cable system.
Is this heater used to heat flowing crude oil or natural gas?
No. This product provides localized wellhead heat retention, not bulk temperature rise of a flowing production stream. In-line and circulation process heaters serve a different duty.
How does the thermal-balance principle work?
As the heater temperature rises, heat dissipation increases until a dynamic thermal equilibrium is established under the applicable installation and operating conditions. Temperature stabilizes at that balance; the equilibrium is not a universal fixed temperature.
Does thermal-balance operation require an electronic temperature controller?
The heater’s thermal-balance operation does not rely on a separate electronic temperature-control component. This does not mean the heater can never overheat or that electronic controls are inherently unsafe. Follow the selected model’s operating and installation instructions.
What information should be provided with an inquiry?
Please provide quantity, an application description, installation photographs or drawings, relevant dimensions, available power supply, ambient/site conditions, hazardous-area requirements and required documentation.
What technical documents are available for the selected model?
Contact XGTHERMAL for the applicable datasheet, installation instructions and certification documents. Availability and coverage must be confirmed for the exact model; this page does not establish destination-market certification.
