HP-200 is designed specifically to absorb expanded fluid in closed-loop residential or commercial hydronic heating and cooling systems, effectively regulating pressure buildup and ensuring system safety.
HP-200 has a total volume of 200 liters (53 gallons). The tank is designed for a maximum operating pressure of 10 bar (150 psi) and a maximum operating temperature of 130 °C (266 °F). It is factory pre-charged to 1 bar (15 psi) for stable system performance and is fully compatible with propylene glycol mixture concentrations of up to 50%.
With a diameter of 55.0 cm (21.7 inches) and a height of 104.9 cm (41.3 inches), this stand-model tank comes with a heavy-duty base, providing massive expansion absorption for demanding commercial and extra-large residential climate-control systems
Product Overview
The HP-200 is a 200-liter (53-gallon) hydronic expansion tank specifically engineered for closed-loop heating and cooling systems. It safely absorbs fluid expansion and contraction caused by temperature changes, effectively controlling system pressure and preventing potential hazards.
Built for maximum safety, the tank is constructed from high-quality sheet steel compliant with IAPMO and EN standards. Every unit is welded according to strict ASME procedures and features a specialized, high-temperature-resistant EPDM rubber diaphragm to ensure exceptionally reliable operation under thermal stress.
To guarantee supreme robustness, every Hydro-Plus model undergoes rigorous hydraulic testing at 1.5 times its design pressure. Manufactured with premium materials, these tanks offer a dependable, high-performance safety solution for any professional hydronic climate-control setup.

Key Features & Design Advantages
How the HYDRO-PLUS Pressure Tank Works
In closed hydronic heating and cooling systems, fluid volume changes drastically as the temperature rises and falls. The HP-200 safely absorbs this expanded fluid using a sealed, compressible air cushion space. It stores the fluid securely against the high-temperature EPDM rubber diaphragm, while the air chamber compresses to accommodate the volume change. This mechanism seamlessly controls excessive pressure, protects valves and piping, and maintains safe system parameters without venting fluid.

Frequently Asked Question (FAQ)
A: While you can use multiple smaller tanks, the HP-200 is specifically designed to provide a single, high-capacity solution for systems with massive fluid volumes. Using one HP-200 simplifies your plumbing, reduces the number of potential leak points at connections, and ensures that the nitrogen cushion is concentrated in one place for more stable and predictable pressure regulation.
A: Every HP-200 arrives factory pre-charged to 1 bar (15 psi) with 100% dry nitrogen, meaning it is ready for immediate installation in many standard systems. However, for specialized commercial applications, your installer can easily adjust the pressure via the integrated air valve to match the specific "static height" or fill pressure of your building's system.
A : Yes, the HP-200 is engineered with a heavy-duty, reinforced steel base specifically designed to support the tank's maximum operating weight. At 200 liters, the tank can become quite heavy when absorbing expansion, so our stand-model design ensures the weight is distributed safely and evenly across your mechanical room floor, providing a much more stable setup than wall-mounted alternatives.
