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.
