UNITE designs and manufactures custom skid-mounted filtration and separation systems for oil & gas, petrochemical, chemical processing and power applications. Each integrated package can combine filtration, gas-liquid separation, piping, valves, instrumentation and control systems to match your process conditions and installation requirements.From process data review to factory testing and commissioning support, our engineering team helps you select the right filtration stages, materials, automation level and maintenance configuration for reliable operation.
With optimized flow arrangement, high-efficiency separation performance, and robust mechanical design, UNITE FILTER skid-mounted systems are widely applied in oil & gas, petrochemical, chemical processing, power generation, water treatment, and other industrial applications requiring reliable and integrated filtration solutions.
Unite possesses the engineering expertise to design and manufacture completely independent, fully automated, and complete filtration and process systems.
For many years, Unite filters have been used worldwide to separate solid substances from liquids.
Unite plans, designs, and manufactures filters as standalone units, filter skids, and complete filtration systems, including process engineering and corresponding process guarantees.
When a single filter cannot meet process requirements, on-site integration capabilities, or schedules, only a complete, integrated filtration system can meet the challenge.
Unite has the experience and technology to design filtration systems strictly according to customer specifications. Our technical engineers review the entire process flow to recommend the most effective way to add filtration steps.
The Filtration and Separation Skid-Mounted System is an integrated process solution designed to provide efficient filtration, separation, and fluid purification in a compact, modular package. The system integrates multiple filtration and separation units, piping, valves, instrumentation, control systems, and supporting components onto a single skid structure, enabling fast installation and reliable operation.
Designed according to specific process requirements, the skid-mounted system provides customized solutions for gas-liquid separation, solid-liquid filtration, and multi-stage purification processes. The modular design simplifies transportation, installation, commissioning, and maintenance while reducing overall project execution time.
The system adopts advanced filtration and separation technologies, including cartridge filtration, coalescing separation, cyclone separation, and automatic self-cleaning filtration, to effectively remove solid particles, liquid droplets, oil mist, and other contaminants from process streams.
The key to Unite Filters' production of high-quality products is process integration.
Part of this development sequence includes an evaluation of the entire system, leading to recommendations for system upgrades.
Unite Filters' engineering department works with you to create a complete filtration process flow.
To ensure your filter performs optimally, this sequence is displayed on the HMI screen and includes all necessary steps, such as filling, pre-coating, filtration, cleaning, repulping, drying, discharge, and in-situ cleaning.

A skid-mounted system is a fully integrated filtration and separation unit that includes filters, pumps, piping, valves, and control systems installed on a single steel skid. It is designed for plug-and-play operation, enabling fast installation and easy transportation.
These systems are widely used in industries such as oil & gas, chemical processing, water treatment, pharmaceuticals, power generation, and new energy. They are especially suitable for projects requiring compact design and fast deployment.
Key advantages include reduced installation time, lower on-site labor costs, compact footprint, factory pre-assembly and testing, and higher system reliability due to controlled manufacturing conditions.
Yes. Skid-mounted systems are highly customizable based on process requirements such as flow rate, filtration precision, pressure rating, material selection (SS304/316L, duplex steel), and automation level (PLC or DCS control).
Maintenance is simplified due to modular design. Key components like filter elements, seals, and valves are designed for quick replacement. Many systems also support online backwashing or self-cleaning to reduce downtime.
For high-value, oxidation-sensitive fine chemical materials containing volatile organic compounds (VOCs), UNITE supplied BASF with a modular integrated system comprising a candle filter and a three-in-one filter dryer, also known as an Agitated Nutsche Filter Dryer (ANFD). The solution combines precision pre-clarification, solid-liquid separation, filter-cake washing, vacuum drying, and automatic discharge within an enclosed process. After commissioning, the project achieved a historic high in product purity, increased solvent recovery by 25%, and effectively eliminated odor leakage.
To improve the safety and reliability of aviation-fuel transfer at an engine-testing base, UNITE developed a customized fuel purification system for the Aviation Industry Corporation of China (AVIC). The integrated solution combines two-stage coalescing separation, high-precision particulate filtration, explosion-proof monitoring, automatic drainage, online water-quality monitoring, and a polished SS316L flow path. It was designed to remove free and emulsified water as well as fine particulate contaminants from aviation fuel such as RP-3, helping protect precision aero-engine fuel systems and maintain stable testing conditions.
CIMC Raffles selected UNITE’s customized hydrocyclone desanding systems for multiple deep-water jack-up and semi-submersible drilling-rig projects. Designed for mud-circulation and seawater-treatment applications, the systems remove hard sand particles from seabed-derived fluids before they can damage high-pressure mud pumps, submersible pumps, and valve seals. The solution combines wear-resistant cyclone liners, SS316L or duplex stainless-steel vessels, compact skid-mounted integration, automated sand discharge, and offshore-oriented monitoring and control.
