Our CTU's are designed specifically for use with high output combi ovens. This are an essential add-on to your combi oven purchase and will protect your oven from the effects of limescale. Benefits include: Less breakdowns/callouts required, increased quality of cook, less wear and tear on internal components, more time between standard service callouts. Limescale problems are the primary reason for combi oven breakdowns and having an effective CTU in place will remove this risk.
