• FPLEC 100 kg/h to 500 kg/h vaporizer

This equipment incorporates components designed to guarantee you care-free operation with minimum servicing.
It does however require monitoring to ensure a long service life.
Under the FEED-BACK vaporisation principle, the FPLEC vaporizer keeps the tank pressurised; its power is normally defined according to the maximum flow rate of the facility and the vaporisation storage capacity.

It is essential that installation is carried out correctly. We have produced a sheet listing the various steps, for example putting the system under load and compliance with the connecting piping diameters must be taken into account.
Adjusting the pressure switch gives a correctly-installed facility independent accuracy of various liquid volumes between the storage tank and the vaporizer.

Connecting one of our vaporizers to several tanks therefore poses no operating difficulties.
Our electrical FEED-BACK vaporizers include the following components :

  • A painted, horizontal cylindrical body 20/30 bar following the construction code CODAP 2005 with 92/23/EC markings.
  • An ATEX immersion heater with varying power depending on the vaporizer type (12, 18, 24, 36, 45, 54 KW) fitted with an overheating thermostat with manual reset.
  • A dual-threshold pressure switch (regulation and safety)
  • An FPS-specific set of flanges for ease of maintenance.
Our vaporizers are pre-wired with two cables (power and control), which make wiring easier whilst reducing costs.

 
• Natural vaporisation

The gas is taken directly from the tank roof and the vaporisation heat is drawn from the ambient air.

A maximum flow rate is set for each type of tank and installation weather zone.

• Artificial vaporisation

Feed-back ou Feed-Out
When the ambient air can no longer vaporise the LPG, recourse to other sources of artificial heat is necessary. The heat is transmitted to the LPG by equipment known as a vaporizer.
There are two types of vaporizer which normally operate via electrical resistance or hot water circulation: feed-back or feed-out.
   
 
FEED BACK FEED OUT
Danger of the liquid propane moving towards the use area
Totally impossible through the principle itself Miscellaneous equipment mandatory :
• level gauge
• solenoid valve, check valve, filter, insulation
Production of oils and heavy compounds
Exchanger totally immersed
• no oil production
• gas overheating: thermostat protection
• purge lock 		Exchanged partially immersed
• gas overheating: thermostat protection
• recondensation : concentration of oils
• capacity and purge lock
Liquid gaseous propane circulation
No stratification nor fractional distillation given the twinned circulation :
• taken from the liquid mass
• re-injection in the gaseous mass

 No internal circulation
Increasing the pressure
Simply by adjusting the pressure switch.
Losses cost less than damping the pump's consumption		 By pump and miscellaneous equipment
Simplicity and flexibility
A minimum of equipment
Gas emission always available from the tank		 Need to provide for an emergency gas line
Economy
Maximum use of natural vaporisation
Installation simpler and more economic		 Partial use of natural vaporisation
Installation far more complicated
