ABSTRACT:
The invention comprises an injection tank for cleaning boilers and heat exchangers. The tank is pressurized by connection to a potable city water supply. The filling, pressurization and injection of cleaning of treatment materials are carefully controlled by the provision of control and check valves on the inlet and outlet of the tank. An interior perforated tank baffle assures that the treatment materials are fully cleared from the tank during injection and thoroughly mixed with pressurized incoming water. The tank is light and portable without requiring separate powered pressurization means.
