Vacuum Boiler

Product Category : Vacuum Boiler

1. The integral design of boiler proper, energy saving device and flue condenser has advantage of compact structure and easy installation.

2. The cascade utilization of exhaust heat has a better energy saving effect, with a thermal efficiency over 100%.

3. It supplies water with a conversion control technology, which can realize continuous water supply, and make the water level and pressure in more stable state.

product description

1. The integral design of boiler proper, energy saving device and flue condenser has advantage of compact structure and easy installation.

2. The cascade utilization of exhaust heat has a better energy saving effect, with a thermal efficiency over 100%.

3. It supplies water with a conversion control technology, which can realize continuous water supply, and make the water level and pressure in more stable state.

4. It adopts a PID combustion technology (i.e. full automatically proportion regulation + integral, differential regulation), which can always make the motor operate in a efficient and power saving state, and reduce operation noise and decrease operation cost at same time.

Rated evaporation rate of integral type saturated steam boiler: 1-20t/h
