Features

APPLICATION: Federal Type HTCR Condensation Return Units are designed to handle condensate at temperatures up to 250 degrees F, returning from air conditioning absorption coolers, process equipment and some space heaters. Since the receivers are non-vented, they permit pumping the condensate with a minimum temperature drop and flash loss. A single unit has one pump and motor, one float switch and one receiver, mounted on a steel base, with the pump suction pre-piped and the controls pre-wired. A duplex unit has two pumps and motors, two float switches and one receiver, mounted on a steel base, with the pump suctions pre-piped and the controls pre-wired.

RECEIVER: The receiver is designed for non-vented use, with a heavy steel shell and dished steel heads, rated for 30 psi maximum working pressure. ASME labels are available as an option. Each receiver is fitted with a gauge glass, a column thermometer, a compound pressure gauge, a drain connection and a thermostatic vent for automatically eliminating non-condensable gases.

PUMPS: Pumps are close-coupled, bronze-fitted with mechanical shaft seal. Each pump has a standard centrifugal main impeller plus a suction inducer impeller, allowing it to operate with only 2-ft. NPSH available. Each pump has a discharge pressure gauge and a suction line gate valve.

MOTORS: Motors are open drip-proof, ball-bearing type, operating at 1750 RPM or 3450 RPM, and are rated 1/60/115/230V. or 3/60/208-230/460V. Totally enclosed and explosion-proof motors are available as an option.

FLOAT SWITCHES: A float switch is mounted on the receiver for each pump, to provide automatic on-off control, and factory wired to the applicable motor or motor starter. An alternating float switch can be substituted for the two standard float switches on a duplex unit, to provide alternation and 2-pump simultaneous operation if required.

MOTOR STARTERS: An across-the-line magnetic starter is furnished for each motor (except small single phase motors), and is factory wired to the float switch and the motor. Combination starters or a duplex control panel can also be furnished (as an option), mounted and wired on the unit. Starter enclosures other than standard general purpose enclosures can also be furnished as an option.

OTHER MODIFICATIONS: Non-standard receiver sizes; galvanized receivers; special receiver tappings; manhole; drain valve; suction line strainers; magnesium anode; high and/or low water alarms; inlet strainer; inlet baffle; non-standard motor and control enclosures; control modifications.
