HOT WATER BOILERS
The ZVBA Hot Water Electrode Boiler is an immersion type boiler that produces hot water directly. It uses a gas pressure system to prevent the water in the inner vessel from steaming. Water circulates between the outer and inner tank. Power is regulated by the water level in the inner tank, ie, the amount of water in contact with the electrodes. The hot water is directly pumped out of the boiler and transfers energy via a Plate Heat Exchanger.
The hot water boiler can regulate the power output between 3-100
Medium Voltage Input 6–24kV
Power Input 5-40MW
Temperature Max180C (350F)

HOT WATER BOILER FEATURES
- Direct Hot Water generation up to 350F
- No steam-water heat exchanger required
- Very fast startup from hot standby (<3 mins)
- Uses nitrogen for boiler pressurization
- Inherently safe - low water auto shutoff
STEAM BOILERS
The ZDKI steam boiler is an immersion type electrode boiler. It has an outer vessel and an inner tank. Water circulates between the outer and inner tank. Power is regulated by the water level in the inner tank, ie, the amount of water in contact with the electrodes. This gives the ZETA boiler very fast startup time and modulation rage between 3-100%. ZETA Steam Boilers accepts power between 5-70MW. It can produce high steam pressure up to 950 psig. Its efficiency is nearly 100% without the only energy loss through insulation and blowdown. Due to large steam space of the immersion boiler and very calm steaming surface, it can generate very clean steam with very little carryover. That is one the reason why ZETA steam boilers are the preferred auxillary boilers in the nuclear power plant, where they require 99.9+% steam quality.
Medium Voltage Input 6–24kV
Power Input 5-70MW (220K PPH)
Steam Pressure Up to 950 psig
Efficiency >99.8%
STEAM BOILER FEATURES
- High steam pressure up to 950 psig
- Very high steam quality (>99.9%)
- Very fast startup from hot standby (<5 mins)
- Inherently safe - low water auto shutoff
