HMIs for the Oil, Natural Gas, and Energy Industries

VarTech Systems' industrial HMIs are designed for safety in the oil, natural gas, and energy production industries, including outdoor environments and C1D1 and C1D2 hazardous areas.

Key Features

C1D1 Area Safety

Ready for environments where ignitable concentrations of flammable gases or vapors are present under normal circumstances, our ToughStation computers, monitors, and kiosks offer purge systems, a requirement for C1D1 areas.

In the event of an external fire or explosion, our rugged enclosures are non-incendiary.

Sunlight-Readable Displays

Ready for outdoor applications such as energy distribution facilities, our units offer upgrades that include sunlight-readable LCDs and components designed for reliable functionality in extreme high and low temperatures.

HMI Solutions for Extreme Temperatures

Whether your facility is in the arctic cold, the desert heat, or somewhere in between, our units are built-to-spec to provide an HMI solution for the requirements of your application.

Our ToughStation and DiamondVue HMI systems extreme temperature package offers operability in temperatures ranging from -20° Celsius to 60° Celsius (-4° Fahrenheit to 140° Fahrenheit).

Our NEMA 6 and IP67-rated All-Weather units offer upgrades for reliable operation in an even greater temperature range: -20° Celsius to 70° Celsius (-14° Fahrenheit to 158° Fahrenheit).

C1D2 Area Safety

Housed in stainless steel NEMA and IP-protected enclosures, our DiamondVue and ToughStation C1D2 area HMI solutions allow for the safe operation and monitoring of critical systems and processes.

Offshore Oil Rig

NEMA and IP Protection

Ready for outdoor applications, our units are housed in NEMA enclosures with IP protection.

IP65, IP66, and IP67 Protection

Our industrial monitors and computers are always customized to the needs of the end user's application. Depending on the product line that best suits your needs, our HMIs offer IP65, IP66, and IP67 protection against dust ingress, a feature critical for hazardous areas.

NEMA 4, NEMA 4X, and NEMA 6 HMI Enclosures

Our HMIs come in NEMA 4, NEMA 4X, or NEMA 6 enclosures protecting our products from water ingress, perfect for environments facing saltwater exposure and precipitation such as rain or snow.


Rugged Touchscreens

From an ultra-compact 6.5" display size to 43", VarTech offers displays for applications where space is restricted and where space is abundant.

Our industrial touchscreen monitors and computers provide several options for compatibility with gloves in operator interface applications where user safety is paramount. Touch technology options include resistive, capacitive, PCAP, and the ultra-rugged ArmorTouch.

Peripheral Devices

ToughStation kiosks are designed with stainless steel enclosures and fully sealed keyboards to provide a complete HMI system.

Always designed to your exact requirements, our custom operator workstations have options including but not limited to RFID readers, biometric fingerprint scanners, touchpads, and function buttons, providing security, process safety, and convenience to operators.

4G-LTE Connectivity

Our DiamondVue and ToughStation HMIs include options for mobile network connectivity, offering instantaneous transfer of collected data for monitoring systems in remote environments such as offshore applications.

Product Lines Used in the Oil, Natural Gas, and Energy Industries


Designed for safety in hazardous area HMI operations, ToughStation units' stainless steel enclosures are fully sealed with NEMA 4X and IP66 protection. According to the needs of your application, they are ready to serve as C1D1 and C1D2 hazardous area computers and monitors.

Industrial Kiosks

Excellent for operating and monitoring systems in the oil, gas, and energy industries, ToughStation HMI kiosks offer fully sealed keyboards and options for additional peripherals such as RFID readers, biometric fingerprint scanners, and thermal printers.

In addition, they are designed for safe operation in the extreme environments of C1D1 and C1D2 areas.


Ready for industrial applications, including C1D2 areas, our DiamondVue HMI products offer reliability in the energy industry, where operational efficiency is a top priority.

Often equipped with 4G-LTE mobile connectivity for use in remote areas, they provide NEMA 4 or 4X and IP65 or IP66 protection against dust and water ingress.


Our NEMA 6 and IP67-rated All-Weather computers and monitors provide ultimate protection in outdoor environments.

They are easily customizable for operating and monitoring outdoor processes such as oil drilling platforms, pipelines, and energy grid applications.
