TP-60 is a high-capacity expansion tank specifically engineered to absorb expanded water in closed, hot water systems as domestic water is heated.
TP-60 has a total volume of 60 liters (14 gallons). Built for safe and demanding continuous use, this tank is designed for a robust maximum operating pressure of 10 bar (150 psi) and a maximum operating temperature of 90 °C (194 °F).
It is factory pre-charged with nitrogen to 3.5 bar (50 psi) for highly stable and safe system performance. With a diameter of 39.0 cm (15.4 inches) and a height of 59.0 cm (23.2 inches) including its heavy-duty base, this highly durable tank is ideal for mid-sized commercial and large-scale residential water heating setups requiring superior thermal liquid expansion management.

Product Overview
The TP-60 is a 60-liter (14-gallon) high-capacity expansion tank engineered to optimize the safety of large-scale closed-loop hot water systems. It serves as a powerful safety buffer, absorbing thermal expansion to stabilize internal pressure and protect your heating infrastructure from mechanical fatigue and relief valve discharges.
Key technical advantages include an FDA-grade polypropylene liner and a heavy-duty butyl rubber diaphragm, ensuring a contaminant-free environment. This internal architecture completely isolates water from the carbon steel shell, providing superior pressure regulation and exceptionally safe operation for high-demand potable water applications.
Built for heavy-duty endurance, the TP-60 features a premium stainless-steel connection and a Triple Grade Almond (RAL 1015) epoxy finish for maximum corrosion resistance. This unit delivers a maintenance-free, industrial-grade performance that guarantees the longevity of your system and your absolute peace of mind.

Key Features & Design Advantages

How the THERMAL-PLUS Pressure Tank Works
In closed hot water systems, thermal expansion occurs naturally as domestic water is heated. The TP-60 works in conjunction with a backflow preventer or check valve to safely absorb this expanded water. It stores the expanded water securely between the heavy-duty butyl rubber diaphragm and the polypropylene liner, while the nitrogen-filled air chamber compresses to accommodate the volume change. By controlling this excessive pressure, it safely maintains water pressure levels and avoids relief valve discharge.
Key benefits
Typical Applications
Frequently Asked Question (FAQ)
Yes. With a substantial 60-liter (14-gallon) capacity and a 1-inch stainless steel connection, the TP-60 is an excellent choice to manage the higher volume of thermal expansion typically seen in multi-family apartments, small hotels, or mid-sized commercial water heating systems.
No. Unlike standard air-filled tanks, the TP-60 is pre-charged with 100% Nitrogen. Nitrogen's stability prevents permeation and does not drastically expand or contract with temperature changes, providing a much more reliable and maintenance-free compressible air cushion.
Absolutely. Continuous relief valve discharge is a primary symptom of unmanaged thermal expansion. The TP-60 safely stores this expanded water volume, effectively regulating system pressure and preventing your relief valve from triggering.
