Maintaining proper system pressure is essential for the longevity and efficiency of your hydronic heating installation. The CX84-125 by Taco serves as a high-capacity 23-gallon diaphragm expansion tank, engineered to absorb excess pressure caused by thermal expansion within closed-loop systems. This robust unit, identified by model number CX84-125, effectively safeguards your piping, pumps, and boiler components from stress induced by fluctuating water volumes.

Inside the vessel, a heavy-duty diaphragm creates a permanent barrier between the system water and the pre-charged air cushion. This design prevents oxygen ingress, which is the primary driver of internal corrosion in hydronic heating systems. By effectively managing thermal expansion, the tank helps prevent relief valve weeping and system pressure spikes, ensuring consistent performance across residential and light commercial applications.

Key System Performance Baselines:

  • Pressure Management: Designed to stabilize system pressure by absorbing expanded fluid volumes during temperature increases.
  • Corrosion Prevention: Utilizes a high-grade diaphragm to maintain a permanent air-water separation, minimizing oxygen-related internal rust.
  • System Longevity: Protects vital boiler components and pump seals from premature failure caused by excessive hydraulic stress.

⚠️ Application Profile: Ideal for closed-loop hydronic heating systems, radiant floor heating, and baseboard circulation networks requiring substantial volume expansion capacity.
