Thrush Duplex Commercial Pressurizers are pre-engineered pressure booster packages that increase system pressure and maintain the flow necessary to meet changing system demands. The constant pressure feature is unique and sets Thrush DCPs apart from other booster packages. Constant pressure on the top floor of a building ensures not only adequate flow but also, the efficient operation of water use fixtures and appliances such as flush valves, washdown bowls, dishwashers, washing machines and shower heads. Pressure boosting, without constant control of pressure, will cause demand pressure fluctuations. This will result in either too little or too much operating pressure at critical fixtures and appliances resulting in improper operation.
High-rise buildings, apartment complexes, office buildings and many other commercial and industrial facilities. The new Thrush DCP is engineered for use as a stand-alone system or as a supplemental package when additional boost in water pressure is required.
Multiple Installations on Alternate Floors
Pressurizers can provide incremental pressurization for blocks of floors. Eliminates the need for a large central booster system. Ideal for modular building techniques.
Hospital/Research Facilities
Ensure constant pressure at critical points of use such as laser equipment and lab cooling systems.
Industrial Point of Use
Provides required pressure of process lines at point of use. Hydraulic pressure, cooling and flushing.
Off Peak Use
Provides minimum pressure during periods of low usage (weekends) and keeps main booster system off.
2. Pressure regulation is controlled by our unique Boostrol® valve which regulates and maintains a constant pressure regardless of fluctuating supply pressure or changing flow demand. Our Boostrol valve is also field adjustable to meet the application, and is a check valve that prevents water from flowing back into the city supply and controls minimum run time for the pump. This ensures that whenever system demand requires the pump to start, it will run for a minimum of three minutes no matter how short the demand.
3. Water storage is contained in a pre-pressurized diaphragm-type hydro-pneumatic storage vessel which provides a pressurized reservoir of water for peak load and minimum usage. This keeps the pump from starting for small infrequent demands.
4. Operation of the Pressurizer is controlled with a pump pressure switch set with a 20 psi differential system that starts at low end and shuts down at high end. All DCPs also have a low suction shut-down to prevent negative pressure draw on city mains and protect the pump from running dry.
5. Automatic pump alternation to equalize pump wear and to exercise the lag pump is a standard control feature. The control panel is also equipped to automatically transfer operation to the lag pump should the lead pump fail.
