OUR USP – 100% Nitrogen-Filled Pressure Tanks

At Assa Aqua, we differentiate ourselves by offering 100% Nitrogen-filled pressure tanks, ensuring superior performance and longevity. Unlike conventional tanks that use air, our Aquasky tanks come pre-charged with pure Nitrogen (N₂), making them truly maintenance-free.

Why Nitrogen?

✅ No Pressure Loss – Nitrogen is less likely to migrate through diaphragms compared to oxygen, eliminating the need for frequent air refilling.
✅ Stable & Reliable – As an inert gas, Nitrogen does not react to temperature changes, ensuring consistent pressure and performance.
✅ Energy Efficient – Reduces pump cycling by 15%, leading to significant electricity savings annually.
✅ Longer Tank Life – Prevents oxidation and moisture-related damage, enhancing durability.

With Aquasky’s exclusive nitrogen-filled technology, we guarantee the highest quality pressure tanks that require minimal maintenance while delivering maximum efficiency.

Thermal Plus

Thermal Expansion Tank: Safeguarding Your Hot Water System

The THERMAL-PLUS thermal expansion tank is engineered to protect your closed, hot water system from the damaging effects of thermal expansion. As domestic water heats, it expands, and without proper management, this expansion can lead to excessive pressure, potentially causing relief valve discharge, leaks, or even more serious hazards.

Reliable Pressure Control and System Protection:

THERMAL-PLUS expansion tanks are designed to effectively absorb the expanded water volume, maintaining safe and consistent pressure levels within your water heating system. By accommodating the expansion, these tanks prevent overpressure and safeguard your plumbing system from potential damage.

High-Quality Construction for Long-Term Performance:

Built to last, THERMAL-PLUS expansion tanks feature a durable stainless steel system connection for corrosion resistance. Inside, a polypropylene liner effectively separates the water from the tank shell, while a heavy-duty butyl rubber diaphragm ensures reliable separation between the water and the 40 PSIG nitrogen pre-charge. This robust construction guarantees long-term performance and peace of mind.

Essential Component for Safe and Efficient Operation:

THERMAL-PLUS expansion tanks work in conjunction with a backflow preventer or check valve to ensure the integrity of your water system. By controlling excessive pressure generated by the water heater, THERMAL-PLUS provides an essential layer of protection, making your home’s hot water system safer and more efficient. Invest in a THERMAL-PLUS tank and enjoy worry-free hot water for years to come.

Pumplus Series

Consistent Water Pressure, Enhanced System Efficiency

The PumPlus Pressure Tank is a vital component of any pressurized water system, ensuring a consistent and reliable water supply at your desired pressure. This innovative tank design features a diaphragm that separates the stored water from a pressurized air chamber. This unique configuration allows the tank to store supplemental water, creating a supply buffer that significantly reduces the number of pump cycles required to maintain consistent pressure.

Optimized Performance and Protection:

By minimizing pump starts, the PumPlus Pressure Tank not only conserves energy but also extends the life of your pump. The diaphragm’s tension plays a crucial role in maintaining stable water pressure, guaranteeing optimal performance for appliances like dishwashers and washing machines, as well as providing a robust and satisfying flow for showers and baths.

Energy Savings and Maintenance-Free Operation:

The PumPlus Pressure Tank is an energy-saving solution that requires no maintenance, offering long-term reliability and peace of mind. When paired with a properly sized pump, the PumPlus tank works in harmony to meet your water demands efficiently, delivering years of dependable service and consistent water pressure for your home or business. Invest in the PumPlus Pressure Tank and experience the benefits of a truly optimized water system.

SELECTION TOOLS

Years of experience and excellent customer service, Assa Aqua has full of experience in sizing your system. Our design engineers, retailers and technicians the support they may need when calculating formulas and evaluating technical data. A tool makes it difficult to simple. This tool is a quick and precise tool in order to find the best solution when it comes to sizing Assa Aqua Plus products. Easy Click in pressure information comes the excellent size pressure tank showing for your system.

PumPlus Pressure tank is an essential part of a pressurized water system that provides water pressure at a set level. The tank stores supplemental water between diaphragm and liner, and the pressurized air chamber is able to create a supply circle. This process reduces the number of times the motor need to start in order for the system pressure to remain at the set level.

Assa Aqua has invented the leak-safe technology and applied on the stainless connector for the pre-pressurized water storage tank 18 years ago, and they are the standard of the industry for drinking water tank. The polypropylene liner and the butyl diaphragm are made with FDA materials and prevent water from making contact with the metal tank for cleaner, fresher and better tasting water

Like every closed system in which a liquid’s temperature changes, a solar installation also needs an expansion vessel. The Solar-plus expansion vessel plays an important role in this regard when it comes to maintaining pressure.

Hydro-Plus Hydronic Expansion tanks are designed to absorb theexpanded fluid in closed-loop of residential or commercial hydronic heating and cooling systems to control pressure build up. Hydro-Plus expansion are tanks composed of a tank in sheet steel which incompliance with IAPMO and EN Standard and welded according to ASME & EN procedure by certified welder.
