The SHADOW US Patent No. 8,069,723 B2
Bulldog Boiler, Ltd.
has been in the boiler business since 1908, and we've learned a few things along
the way. Consequently, we have developed an electric modulating feed water system
for boilers that provides just the right amount of water to the boiler at just the
right time. We call our system SHADOW. The Shadow is an all solid
state control system. The actuator is 110 volts AC with a capacitance probe level
sensing system.
Just the Right Amount of Water
at Just the Right Time!
