Standard Components (Back View)
SRV / Drain Plug
A 50 psi SRV / drain plug are located on the back of the UltraDoser
®
LN
2
Dosing System unit. When removed,
this allows the LN
2
to drain from the UltraDoser body.
The 50 psi safety relief valve (SRV) is provided to protect the unit against over pressurization. If the pressure
inside the unit reaches 50 psi or greater, the safety relief valve will vent excess pressure. Under normal
operating conditions, the SRV should not vent.
Vent Heater
The UltraDoser unit has a self-regulating vent heater. The maximum temperature of the vent heater is 150ºF
(65ºC) and prevents frost or ice formation at the vent area. The heater is held in place by a set of o-rings. If
needed, the vent heater can be removed by slipping it off of the vent area.
Optional
Components
ElectroPneumatic (EP) Actuated Valve
If ordered, the UltraDoser system has an ElectroPneumatic actuated dosing valve. The valve is driven by a
pneumatic cylinder. Gas pressure to the cylinder is controlled by a 24 volt solenoid valve.
CryotechFlex Hose
A vacuum insulated hose that provides a connection between the UltraDoser unit and the LN
2
supply.
