VO expansion vessels are designed to contain diathermic oil in a closed circuit, in full respect of the P.E.D. Directive 2014/68/EU.
These expansion vessels are generally used in industrial systems to compensate for the thermal expansion of the oil during the generator’s start-up and switch off times.
Fiorini VO expansion vessels, collecting the diathermic oil, also act as temporary storage during maintenance.
All the Fiorini pressure tanks, including the VO expansion vessels for diathermic oil, can be built, on request, with customised designs to meet individual specific needs and even in small batches.
From 300 to 20000 Litres
