CRU 200 and 500 Series Condensate Recovery Units (fixed speed pumps)
Description The Spirax Sarco CRU 200 and 500 series condensate recovery units with fixed speed pumps are designed to handle hot flashing condensate entering the receiver (up to 98 °C) which is commonly returned for use as boiler feedwater. The standard range can handle quantities up to 20 m 3 /hr, duty/assist with varying pump delivery heads. For higher duties please contact Spirax Sarco. The package comprises - receiver, frame, pumps, valves, level controls and pre-wired control panel. Note: 1. System head regulation valves are not supplied as part on the unit, but it is recommended they are incorporated into the discharge pipe work. 2. This unit is not suitable for outdoor use, please consult Spirax Sarco for a bespoke solution. 3. This unit is not designed to accept nozzle loads from connecting pipework. Receiver Receivers are manufactured from 304 stainless steel. They are fitted with an adequately sized vent, overflow and inlet connections flanged to PN16. Vessels are leak tested. A water level gauge is fitted as standard, with integrated level control and high alarm. Frame The frames are manufactured from carbon steel powder coated (black) or 304 stainless steel. Pumps (fixed speed) Pump housing and impellers are constructed from stainless steel and are designed for low NPSH conditions to handle hot condensate with the minimum of flooded suction. They are directly coupled to TEFC motors having class F insulation (class B temperature rise) motor enclosure class IP55. Control

The electrical supply required is 380 - 415 volts, 3 phase, 4 wire, 50 Hz. BMS interface is provided to monitor pump healthy and high level alarm conditions. Pump fitting The motors and pumps are mounted under the receiver and are each connected to suction pipework incorporating isolation valves. Each pump discharge is fitted with a non-return valve suitable to connect to a PN16 flange. Note: See note 1 regarding discharge regulation.
Standards This product fully complies with the following directives - European Machinery Directive 2006/42/EC,
