In indirect steaming chambers, hot water or steam from an external source – the user’s boiler, indirectly, through a tubular heater immersed in a stainless steel tub, evaporates water from the tub and thus creates an enough amount of moist steam for steaming. It is a closed heating system, there is no loss of steam or hot water. The condensate formed during steaming is returned to evaporation, while the water in the tub is replenished automatically. The steaming process is more complex, but with minimal water and energy consumption for steaming.
The steaming process is conducted automatically, and the steaming regimes are based on the requirements of users, experience and cooperation with the profession.
