Explore Industrial Process Filtration Proucts
HILCO has seen many changes since our first oil reclaimer was built in 1925. The problems have become more complicated, and the filtration techniques have grown more sophisticated. Hilliard is first and foremost an engineering company. Every process filter we have developed and tested by our team brings fluid contamination problems under control. Our process filters have been assisting customers with amine solutions, napthas, glycols, water and fuel products for over 100 years. These systems are custom engineered and HILCO welcomes the opportunity to review your requirements to increase filtration efficiency while reducing your filtration costs.

HOW IT WORKS
How Process Filtration Work
Since HILCO’s founding in 1915, our filtration equipment has earned a trusted reputation among both Original Equipment Manufacturers (OEMs) and end users worldwide. This reputation is built on a long legacy of filtration expertise combined with world-class manufacturing capabilities.
One of HILCO’s defining advantages is our fully integrated design approach: every filtration system features a precisely engineered HILCO vessel paired with a perfectly matched HILCO cartridge, both manufactured at the same facility. This level of control ensures optimal performance, reliability, and consistency across all products.
By manufacturing both vessels and cartridges as a complete system, HILCO has not only established the industry benchmark for filtration performance but has continually raised the standard for more than a century.

Process filters are most commonly found in Petro chemical, refinery, and hydro processing.
