Electric condensate recovery units ECRU

DESCRIPTION

The ADCAMAT ECRU series electric condensate recovery units are recommended in the transfer of high-temperature water such as hot condensate, to a higher elevation or pressure. This condensate is usually used as boiler feed water. The standard models are prepared for flows up to 20 m3/h, or higher on request.

The units are composed by a condensate vessel (receiver), a metallic support frame, electric pumps, level controls, valves, prewired control panel and pipework’s for connections between the different elements of the units

OPERATION

The condensate is brought into the vessel through the inlet connections, with stainless steel sparge pipes, located on the top of the vessel. As the condensate level rises it will trigger the level control system to start the pumping process. In normal operating conditions, the pumps will work in alternating mode, which means they will alternate duty at the end of each cycle. In the event of a peak load, the level will continue rising eventually triggering the cascading switch which will make both pumps work simultaneously to relieve this peak demand

MAIN FEATURES

Condensate vessel – Completely manufactured from AISI 316 stainless steel or carbon steel, with inlet connections, overflow, air vents, drain, pump feeding outlets and a magnetic level indicator with bi-stable switches.

Valves and ancillaries – Includes full bore ball valves at the pump suction ports, manual regulating valves for system head regulation at the pumps discharge, seamless carbon steel pipes, strainers and pressure gauges.

Metal frame – Manufactured from structural steel, sandblasted and painted.

Pumps – Manufactured from stainless steel or cast iron, capable of handling hot condensate up to 98 ºC and designed for low NPSH.

Control panel – Metal enclosure rated to IP65 or higher. Features alternating and cascading (simultaneity) functions, pump fault indication for each pump, low and high-level alarms, pump dry run inhibitor, operating mode selector switch and volt-free telemetry terminals for remote stats. The unit requires a 3 phase, 380-415 VAC, 50Hz power supply.
