Filtration of hydraulic oil, lubricating oil, and other technical fluids in cold climates places different demands on filtration systems compared to operation at normal working temperatures. As temperature decreases, oil viscosity increases, which directly affects flow rate and filtration efficiency. Without appropriate measures, this can result in inefficient filtration, increased stress on components, and reduced operational reliability in hydraulic systems.

The FH700 is a high-pressure hydraulic filter housing developed for use in some of the most demanding operating environments within subsea, offshore, and land-based high-pressure systems. The product is designed for applications with extremely high operating pressures, where reliability, material quality, and safe handling are critical.

Effective seawater filtration requires equipment that withstands harsh environments, fluctuating water quality and high particle loads. This vertical, automatic self-cleaning filter in duplex is developed for aquaculture and combines robust materials with a scraper system that removes shells, seaweed and other particles without interrupting operation.

Fresh Water Norway has chosen a self-cleaning filtration solution from Ditech to ensure consistent quality of both process water and intake water. The automatic system provides reliable operation and efficient filtration without the need for manual cleaning.

Moisture, dust, and particles can compromise oil, hydraulic systems, and tanks, leading to degradation, corrosion, and costly maintenance. By selecting the right breather filter, you not only protect your equipment but also gain insight into what is happening inside your system. Proper breather filtration can extend equipment life, reduce downtime, and save significant costs.

In water treatment, the terms water filtration and water separation are often used interchangeably, but the processes are fundamentally different. Choosing the right method and equipment can have a significant impact on treatment efficiency, final water quality, regulatory compliance, and operating costs.

Self-cleaning automatic filters are designed for efficient mechanical removal of both solid and soft particles from water and process fluids. These filters are especially suitable for applications requiring high operational reliability, limited space, and automated operation, such as aquaculture, power plants, industrial process facilities, and water treatment systems.

In aquaculture, the process industry, and the marine & Offshore sector, strict requirements are placed on water quality and operational reliability.
