Electric condensate recovery units PRIMA-THERM ESVK

DESCRIPTION:

The PRIMA-THERM ESVK 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 feedwater. The standard models are prepared for flows up to 30 m³/h, or higher on request. The units are composed of an horizontal condensate vessel (receiver), a metallic support frame, electric pumps, level controls, valves, prewired control panel and pipework 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.

Pipework, valves and ancillaries – Includes full bore ball valves at the pump suction ports, manual regulating valves for system head regulation at the pumps discharge, pipework, strainers and pressure gauges.

Metal frame – Manufactured from structural steel (sandblasted and painted) or stainless steel (sandblasted).

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

Control panel – Metal enclosure rated to IP 65 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 to 415 V AC, 50 Hz power supply.
