Modular Production Equipment
Horizontal Heater Treater
Horizontal heater treaters are a type of 3-phase separator that separate oil, water, and gas from well production using heat and gravity, helping prepare crude oil for transport or storage. They are commonly used for higher volume applications and provide longer retention time for separation.
Vertical Heater Treater
Vertical heater treaters are a type of 3-phase separator that separate oil, water, and gas from well production using heat and gravity, helping prepare crude oil for transport or storage. They are often used in applications where space is limited or where head pressure is required to push fluid to storage tanks.
Horizontal Gas Separator
Horizontal 2-phase gas separators are used in oil and gas production to separate gas from liquid hydrocarbons and water. Their horizontal design provides longer retention time, making them well-suited for handling higher liquid volumes and improving separation efficiency before downstream processing.
Vertical Gas Separator
Vertical 2-phase gas separators are used in oil and gas production to separate gas from liquid hydrocarbons and water. Their vertical design is ideal for handling high gas volumes and applications with limited space, providing efficient separation before further processing.

Desander Tanks – Steel & Fiberglass Options
Desander tanks are used to separate sand and solids from production fluids, protecting equipment and improving system performance. Available in steel or fiberglass, each design offers advantages depending on operating conditions and application requirements.
