Hy-Pro vacuum dehydration units are designed to remove contaminants (such as water) continuously and efficiently from hydraulic oil. Manufactured in the US by Hy-Pro Filtration, Hytec Fluid Technology (HFT) is the official distributor and is authorised and technically skilled in the installation and service of the vacuum dehydration units.

The units are designed to be safe and easy to operate and install. “This technology is so versatile that it can be deployed in any industry sector. HFT has successfully installed static assemblies in the power generation, petrochemical, oil and gas as well as pulp and paper industries, and receives positive feedback on a regular basis,” comments HFT technical division Cameron Milner.

The Hy-Pro dehydrator removes free, emulsified and dissolved water, as well as gases, from hydraulic oil. It achieves this by heating the oil and passing it though a vacuum chamber, where the dissolved gases and water are boiled off. The oil is then passed through a particulate filter which automatically removes all particulate matter from the oil. This helps to extend component and bearing life, as well as the use-life of the oil.  

The dehydrator system includes a pre-programmed, relay-enabled control panel, which provides the unit operator with full access to the necessary functionality of the machine, including monitoring telemetry for relative humidity (RH) percentage, ISO cleanliness, temperature and pressures.  

“Due to the unique process flow of system, the dual condensate tank setup allows this assembly to sustain its own vacuum and facilitates a controlled environment and continuous operation,” says Milner. Certain parameter configurations must be programmed before deployment, but once complete, the system continues to operate automatically. It shuts down as a failsafe in the event of a fault. “As for maintenance, the units will only require replacement of the breather elements (environment dependant) as well as the post element replacement for the oil conditioning circuit. This is indicated with onboard monitoring technology and the unit operator can determine the procedure based on the telemetry,” adds Milner.

The Hy-Pro unit carries a factory safe warranty of 12 months and is backed up with support and service agreements from HFT, which holds stock of all serviceable parts and replacement components. HFT is a Bosch Rexroth South Africa Group company.
