Typical specifications

For LNG fuelling: 
 One or two LNG dispensers with weights and measures approval 
 Super saturated (18 bars – 260 PSI), saturated (8 bars – 116 PSI) and cold (3 bars – 43.5 PSI) vehicles refueling 
 Fueling flow: 150L/min (45 GPM) 

For LCNG fuelling:
 Redundant LCNG pumps 
 2 dual hose CNG dispensers 
 Fueling flow: 800 Nm3/h (30’400 SCFH) 

LCNG Stations (Liquid to Gas) 

The Cryostar LCNG stations are able to refuel CNG vehicles with a 0.05 kW/kg specific power requirement.

LCNG stations usually require LNG storage at minimum of 2 bars/-153°C (29 PSI/-243°F) (no saturation needed). 

These stations are not that sensible to heat entries as the LNG is transformed to gas. 

Typical characteristics for a 800 Nm3/h station 

Maximum fuelling pressure: 250 bars (3625 PSI) @ 15°C (59°F)
Intermediate storage: 300 bars (4’350 PSI)
Flow regulation: with VFD for flow regulation
Average refueling time: 2 minutes for a 80L (21 GAL) tank
Number of vehicles per hour: 12 vehicles/dispenser
Fuelling flow at nozzle: 9.5 KG/min (800 Nm3/h - 30’400 SCFH)
Measurement accuracy: 99.9% (Coriolis)
Station power requirement: Approximately 30KW (0,05 KW/kg)

Our scope of supply
 LCNG High Pressure Pumps
For slow fueling: SDPD (Data sheet)
For standard fast fueling: MRP (Data sheet)
For large size stations: HPP (Data sheet)

 LCNG Line and Buffer Control Skid 
The Cryostar line control panels are designed to control following features:
Line pressure / Vaporizer outlet temperature / Buffer pressure / Buffer valve / Main station shut-off valve 

They are available in 2 different models: 
 The DGCP panel for temperature and pressure control only 
 The BUFFER SKID, for temperature, pressure, and buffer control 
Options available for the BUFFER SKID:
Odorizer inlet point and odorizing system / 3 bank buffer storage supply / Flow metering system for slow filling 

LCNG Station Control System 

The control interface allows the communication between the operator and the LCNG system. A remote access allows station monitoring from any web browser. 

LNG Stations (Liquid to Liquid) 

The Cryostar LNG stations are able to refuel LNG vehicles with a 0,005 KW/kg specific power requirement. 

LNG stations usually require LNG storage from 3 bars/-153°C (43.5 PSI/-243°F) to 18 bars/-110°C (260 PSI/-166°F).
LNG at 3 bars and -153°C (43.5 PSI and -243°F) : « cold LNG »
LNG at 8 bars and -130°C (116 PSI and -202°F) : « saturated LNG » 
LNG at 18 bars and -110°C (260 PSI and -166°F) è « super saturated LNG »

LNG stations are quite sensible to heat entries as the LNG can boil off quite rapidly 

Typical characteristics for a 800 Nm3/h station 

Fuelling temperature: -150°C/-243°F (cold) to -110°C/-166°F (super saturated)
Fuelling pressure: 3 to 18 bars (43.5 to 260 PSI)
LNG pump skid flow: 320 L/min (84.5 GPM) @ 12 bars (174 PSI) diff. pressure
Fueling flow at nozzle: 160 L/min (42 GPM)
Average refueling time: 3 minutes for 450L (118 GAL) tank
Number of vehicles per hour: 10 vehicles/dispenser
Measurement accuracy:

99,5% (W&M MID approved)

Power requirements:

Approximately 20 KW (0,005 KW/kg)

Extended scope 

Moveable stations
The Cryostar moveable stations are the best choice for temporary fuel supply or trial purposes. All equipment is delivered and installed in a 20” or 40” ISO container frame. The storage tank can be placed on the side or the top of the container. 

LNG Container Station 
LNG container mounted systems are delivered complete ready to be used

LCNG Container Station
LCNG container mounted systems are a complete replacement of a CNG station compressor.
