TP-60 Thermal Expansion Tank

60-Liter (14 Gallon) Thermal Expansion Vessel for Closed Hot Water Systems | Aquasky THERMAL-PLUS Series | Made in Taiwan

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.

TP-60

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.

Materials & 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

  • Absorbs excess water during heating to prevent relief valve discharge.
  • Protects water heaters and plumbing from high pressure/leaks.
  • Provides a safe, stable system for residential hot water.
  • High-grade internal liner isolates water from metals, preventing tank corrosion.

Typical Applications

  • Multi-unit residential and commercial closed-loop hot water systems
  • Large-scale domestic water heater installations
  • Commercial plumbing systems requiring backflow preventers or check valves
     

Frequently Asked Question (FAQ)

Q1 : Is the TP-60 the right size for a multi-unit residential boiler system?

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.
 

Q2 : Does the TP-60 require frequent air recharging like standard tanks?

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.
 

Q3 : Will installing the TP-60 stop my water heater relief valve from constantly weeping?

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.
