Thank you very much for the information. I'll forward this to our marketing department.
To be on the safe side, VITO® 50 can definitely filter fryers up to 20litres. But sometimes the VITO®50 works also in a 25litres fryer, if the customer have only one fryer.
e.g.: Two fryers with 20 and 25 litres, the customer should choose a VITO®80.
Trust you got my point.
