When You Buy Round Device 150 m Barrier
When you buy round device 150 m barrier, you need to choose between three basic models: SPA1000, SPA2000, and SPA3000. These are designed for use in applications requiring pressurized fluid. The pressure of the refill unit determines the level of pressure that the barrier can withstand. The three basic models in the SPA range are suitable for hydraulic oil viscosity values between 12 and 90 mm2/s. Your application will determine the appropriate viscosity class.

The DRU system functions similar to the TS system. It creates a barrier pressure without the use of nitrogen. The device has a cooling and storing device to keep the barrier fluid cool. The pressure is increased automatically, usually by piston. Other versions are available on request. Heat exchangers also determine the cooling performance of the device, including different flow rates and available fluids. You can rely on the expertise of EagleBurgmann to choose the right heat exchanger based on your requirements. To learn more about this DRU system, click here.
The DRU system works similarly to the TS system, but without superimposition of nitrogen. The barrier pressure is created through a reference pressure. The barrier fluid is cooled and stored in a reservoir. The DRU system includes a pressure booster to cool the barrier fluid. The DRU system has a piston for pressurization and an automatic pressure booster based on process/medium pressure and transmission ratio. Other versions are available upon request.
Both types of DRU systems perform similar functions to the TS system, except that they do not use nitrogen as a superimposition gas. The barrier fluid is cooled with a heat exchanger while a pressure booster stores and pressurizes it. The pump uses a piston that is governed by the process/medium pressure and the transmission ratio. Other models are available on request. They are specialized in the selection of the best heat exchanger for your application.
The DRU system is similar to the TS system, but it uses a reference pressure instead of nitrogen to create the barrier pressure. The DRU system also has a pressure booster to store and cool the barrier fluid. They can be manual or automatic. Some models have a TS-style regulator, which can be easily configured to accommodate different flow rates. Some of the DRU systems have a pressure booster with a pressure controller.
DRU and TS systems share the same basic concept. The DRU system creates the barrier pressure by the reference pressure without using nitrogen as a superimposition agent. The DRU system is a single unit that also stores and cools the barrier fluid. Some systems come with an optional heat exchanger and may have a programmable temperature controller, which regulates the temperature of the barrier fluid. The DRU and TS systems are similar to the TS but differ in their performance. Get more details about fire barriers on this related post: https://en.wikipedia.org/wiki/Firestop.
