MEGA-450 is the largest component in this pressurized water system line, engineered for high-rise buildings, fire systems, and demanding long-distance pressure support. With a massive 450-liter (120-gallon) capacity, it reliably maintains water pressure at a set, consistent level.
Built for high-stress environments, the tank supports a robust maximum operating pressure of 16 bar. It is factory-pre-charged with 100% nitrogen to ensure highly stable performance and prevent pressure fluctuations caused by temperature changes.
Measuring 65.0 cm in diameter and 140.6 cm in height, the tank features a heavy-duty base for maximum stability. This ultimate-capacity solution is ideal for industrial booster setups requiring exceptional high-pressure performance and flow rates up to 75 liters per minute.
Product Overview
The MEGA-450 is a 450-liter (120-gallon) high-performance diaphragm tank, engineered as the definitive solution for large-scale water system stabilization. Utilizing a specialized FDA-grade polypropylene liner integrated with a premium butyl diaphragm, it ensures a dedicated "Safe Water Zone" by preventing any contact between the liquid and the tank's metallic shell.
Key technical advantages include a 100% Nitrogen pre-charge and a 16-bar (232 PSI) pressure rating, which significantly outperforms standard industry tanks. This configuration ensures more stable pressure cycles and minimizes pump "short-cycling," directly preventing motor burnout and extending equipment lifespan.
Constructed with a heavy-duty cold-rolled carbon steel shell and protected by a triple-grade epoxy powder finish, the MEGA-450 offers superior oxidation resistance. Equipped with a 1-1/4” Stainless Steel lead-free connector, this CE and ISO 9001 certified unit provides an energy-saving, maintenance-free solution for critical high-pressure applications.

Key Features & Design Advantages
How the MEGA-PLUS Pressure Tank Works
The MEGA-450 stores supplemental water between the liner and the heavy-duty butyl rubber diaphragm. When a faucet is opened or an appliance demands water, the compressed nitrogen air chamber pushes the stored water into the system. This allows the system to meet low-volume water demands without immediately triggering the pump motor. By creating this efficient supply cycle, the tank minimizes pump cycling, stabilizes water pressure, and conserves energy.
