  Operating Instruction KSE18  

Description of the apparatus:
The CO2-Flash Evaporator, also called
CO2 Expander Unit, consists in its main parts of:
- a gas outlet nozzle
- a gas inlet
- the tension reliever
- the baffle plate
- and the housing for the electrical connections.

All parts are made out of an Al alloy.
The KSE18 is absolutely maintenance-free.

The CO2-Expander Unit (CO2-Evaporation Unit - KSE18) can be operated in any fitting position.
(Installation position as desired, horizontal or vertically)

Gas intake:
The gas intake is regulated via a high-pressure valve, which is also used to regulate the flow.
This high-pressure valve has factory fitted conical seals with union nuts at the intake and the outlet and can be swivelled around 3600.

Gas outlet:
If there are any blocking valves in the exhaust gas pipes, a savety valve with a release output of at least 100 Nm3/h and a maximum excess pressure of 6 bar must be provided.
!!! When connecting the release pipe it must be noted that the maximum
!!! thread depth of the M16 thread in the appliance is 30 mm. If screws
!!! are used which are too long the appliance will be damaged.

Only the following gaskets and screws should be used for the outgoing gas pipe:
- Gasket C 32 X 42,4 DIN 2633 or
- Gasket C 32 X        DIN 2566
- Screws M16 X 50

The KSE18 CO2-Evaporation Unit (CO2-Expander Unit) is heated using 6 heating cartridges which are connected together for a three-phase terminal.
The connection is carried out in accordance with the enclosed terminal plan.

The heating does not require any control, only a temperature limit. For this purpose there is a temperature sensor in the form an M8 screw in the heater core.

With downstream feeder pipes, starting up is carried out by switching the heating on an opening the high pressure valve. Where the highest possible flow is aimed for, the factory-installed analog pointer thermometer in the exhaust gas pipe should be watched
At 100 Nm3/h the temperature of the exhaust gas is approx. 200 C.
The temperature here should not fall below 00 C.
If the gas throughput is too high and the output limits of the appliance are exceeded, the appliance cools down internally so much that the liquid gas is sublimated and snow forms.
Effective heat transmission is then no longer possible. If this happens, the gas feed must be shut off until the temperature in the gas outlet again displays values above 00 C.

The appliance's heating may remain switched on even without gas throughput without the appliance being damaged.
