Components
50/60 Hz Toggle Switch
- This switch on the front electrical panel is used to select different
phasing circuits for RDK-101D cold head operations at 50 or 60 Hz.
Accessory Receptacle and optional Remote ON/OFF cable
- The accessory receptacle on
the front electrical panel is a 4-socket connector for supplying remote ON/OFF capability. The
remote ON/OFF cable is available as an option.
Adsorber
- The adsorber removes any oil and moisture the gas is carrying which did not drop
out in the separator. The adsorber has a finite life and must be replaced at regular intervals.
Atmosphere Relief Valve [ARV] – The pressure relief valve prevents the compressor from
operating at an unsafe pressure by venting to the atmosphere.
Bulk Oil Separator - Removes much of the entrained oil from the gas stream. This unit needs
no servicing or replacement.
Circuit Breaker
– A 20 A circuit breaker is mounted on the front electrical panel. It provides a
means to disconnect the mains power supply and protects the compressor from electrical
overload.
Cold Head Receptacle - A 28-socket receptacle on the front electrical panel and a cold cable
supplies electrical power from the compressor to the cold head. The compressor can be
supplied with cables for operating CH Series or RDK-101D cold heads.
Compressor Capsule - Helium, scroll compressor with a hermetically sealed motor.
Compressor High Temperature Motor Protector Switch - Located inside the compressor
motor, the switch senses compressor motor temperature and stops the motor if the temperature
is too high. The switch resets after cool down.
Elapsed Time Meter - Located on the front electrical panel, the ETM has a battery-operated
LCD digital display that shows the compressor's cumulative running time in hours.
AVOID INJURY. The compressor’s elapsed time meter contains a lithium
battery. Do not remove the battery. Do not recharge, disassemble, mutilate, wet
or dispose of the meter in fire. Contact local environmental authorities for proper
disposal of the lithium battery.
Electrical Chassis - The electrical box contains electrical components and connections and
distributes power to all system circuits.
Final Oil Separator - Removes most of the remaining entrained oil from the gas stream. This
unit needs no servicing or replacement.
Fuses – Four (4) time delay, 5 x 20 mm fuses, located on the compressor front electrical panel,
protect the control circuit and the cold head supply circuit.
