TK300 Series Expansion Tanks- Heating
Honeywell Expansion Tanks are designed to absorb hot water
expansion in closed heating systems. They are equipped with
butyl diaphragms to separate the air from the system water
(glycol). The tanks are a welded, not clamped design. Pre-
pressurized at 12 psi, the tank keeps fluids circulating and
maintains minimum system pressure. Honeywell tanks resist
waterlogging, loss of pressure through relief valve spills, loss of
BTUs and reduce circulator running time. Use the super efficient
Honeywell PowerVent or air vents to remove air and micro-bubbles
from the system for maximum performance.
