What is Convotherm's Advanced Closed System

Convotherm Advanced Closed System

The ACS+ system ensures peak cooking performance in every Convotherm 4. It guarantees perfect steam-saturation, automatic humidity adjustment in combi-steam cooking and fast, even heat transfer for convection. This delivers an ideal, constant environment in the cooking chamber for all products, from vegetables through meat and fish to side dishes or baked goods, whether fresh, frozen or precooked. Even when the combi oven is fully loaded, you achieve consistently excellent results: evenly cooked, succulent and crispy.

Our ACS system works like a pan lid, keeping heat and moisture in the combi oven so that the temperature rises rapidly and less power and water are required. The new ACS+ system can do even more: it uses smart active control of air input and output. After all, if you want to reduce a sauce, you take the lid off the pan.
