Offline Kidney Loop Designs and Water Removal Systems
Hydraulic and lube oil reservoirs typically have some level of particulate and water contamination. Offline filtration solutions work to lower ISO codes while taking the contamination load away from the primary onboard filtration systems.

Kidney Loop Systems and Purifiers
Maximum Reliability, Lower Cost of Ownership
Kidney Loop systems operate independently of the main system filtration system ensuring no disruption to existing systems. They are designed to resist system shocks, maintaining filtration performance under varying conditions. The independent control of flow rates and pressure optimizes filtration efficiency and effectiveness. Systems can be designed to specific ISO cleanliness targets and operational requirements, ensuring optimal performance for your application.
The systems are equipped with filter elements that have a high dirt holding capacity, effectively removing all types of contaminates down to 1 micron. They are suitable for oil, diesel and biofuels. Hydralogie is a leader in providing standard and custom design kidney loop systems for all industries.
Water in hydraulic, lubrication, heat transfer and insulating fluids adversely affects fluid performance and is a threat to system reliability. The HDP series of purifiers combine the water removal performance of mass transfer technology with high reliability and ease-of-use to help ensure maximum equipment uptime and lowest cost of ownership enabling you to focus on your process and not the equipment.
Our design team can team can assist you with designing, installing and maintaining a system specific for your application.
