Arctic Hybrid Buffer Tank – Pressurized Composite Buffer Tank

The Arctic Hybrid Buffer Tank is a pressurized composite buffer tank designed for hydronic heating and cooling systems. Its composite construction provides a lightweight, corrosion-resistant alternative to traditional steel tanks.

The tank is better insulated than traditional steel designs, approximately half the weight of comparable steel buffer tanks, and designed to help improve hydronic system performance through thermal storage and hydraulic separation.


Key Benefits

  • Corrosion-Resistant Construction: Composite design eliminates the rust concerns associated with traditional steel tanks.
  • Lightweight Design: Approximately half the weight of comparable steel buffer tanks, helping reduce installation labor.
  • Reduced Short Cycling: Helps reduce heat pump, chiller, or boiler short cycling during low-load periods.
  • Hydraulic Separation: Four-port design separates supply and demand circuits, allowing independent circulation for the heat source and system loads.

Specifications & Construction

  • Core: NSF-approved polypropylene wrapped in continuous strand fiberglass with high-temperature resin.
  • Maximum Ratings: 180°F at 75 PSI and 140°F at 100 PSI.
  • Insulation: Closed-cell foam with stated heat loss of less than 1°F per hour.
  • Available Sizes: 22, 40, 55, 80, and 120 gallons.
  • Ports & Features: Four stainless steel side ports, thermal well (except 22-gallon), vent, vacuum breaker, and drain.

Operation & Function

The Arctic Hybrid Tank acts as a thermal energy battery, storing heated or chilled water for use when system demand changes. By separating the high-flow heat pump or boiler circuit from the system's hydraulic loads, the tank can help stabilize system operation.

  • Reduces short cycling of heat pumps, chillers, or boilers.
  • Helps balance multiple low-BTU loads calling at different times.
  • Can serve as both a thermal buffer and hydraulic separator when properly piped.

Efficiency

The supplied product information states that the Arctic Hybrid Buffer Tank provides 41% less heat loss than comparable tanks, helping reduce thermal losses while providing a durable, rust-resistant buffer solution.
