Expansion tanks for use in closed heating or cooling systems are available in various types and sizes. Expansion and pressurisation equipment are often vital inclusions to commercial heating, solar power and cooling systems ensuring performance and corrosion protection. The type and size of tank used is usually governed by the intended application and can range from simple expansion tanks, which are pre-charged and sized according to the design fill pressure and requirements of the system, through to pump controlled pressurisation systems which may include degassing functions.
A constant and predetermined pressure is fundamental to the running and longevity of water based heating and cooling systems. Here the range we supply at Automatic Heating Global offer intelligent yet simple solutions. The Duraflex and Zilmet tanks operate without power and require little to no effort to operate. An internal diaphragm or bladder seals water from the gas compartment which results in prevention of the diffusion of pressured gas into the water so a fully closed system is formed that does not suffer from corrosion or other gas-related problems. Duraflex pressurisation systems combine automatic water make up and deaeration to provide a controlled pressure. An expansion tank of the bladder type is the norm and pressure is applied and controlled by a pump which can also perform vacuum degassing to remove any air from the system that may encourage corrosion, noise and sludge. This active management is superior to conventional expansion tanks. For more information on these systems, visit Expansion Tanks and Pressurisation Systems in our solutions section.
