REASONS WHY OUR LPG VAPORIZERS ARE EXCLUSIVE AND INNOVATIVE
Actually most of countries have norms to use safety devices to avoid LPG liquid phase in grid
distribution.
Normally the solution is to use solenoid or pneumatic valves:
• solenoid valve have to be Eexd certified, they need specific plant and electric switchboard;
• pneumatic valve need air compressor and specific plant
OUR LPG VAPORIZERS DON’T NEED IT

4. Page 4
Most of our competitors produce lpg vaporizers with a gas chamber built-in that can be filled by
LPG in LIQUID phase: a float valve is necessary to avoid LPG liquid phase in grid distribution
OUR LPG VAPORIZERS DON’T NEED IT

5. Page 5
All our lpg vaporizers have installed an
EXCLUSIVE and PATENTED
CONTROL REGULATION VALVE
TOTALLY MECHANICAL
The flow of gas happens by our patented control regulation valve, mounted at the inlet of the
vaporizer (liquid phase)

6. Page 6
It works on the basic concept that, reaching a certain temperature, the LPG enters a gaseous state.
The liquid LPG:
• coming from the tank
• enters into the valve
• passes through the filter
• comes to the shutter which is closed.
If the temperature of the water leaving the exchanger is recorded as being > 50-55°C, the
expansion of the bellows will make the shutter open and let the gas enter into the heat exchanger.
As the user’s requirements vary so does the temperature of the water and consequently also the
opening of the shutter.

7. Page 7
If the need for gas should exceed the heat exchanger’s rating:
• the temperature of the water leaving the exchanger will fall
• the bellows will make the shutter close to reach an equilibrium “GAS FLOW = HEAT
REQUIRED”
This system excludes any possibility of taking up gas in a state close to its re-liquefying.
If the requirement for gas was nil and the water temperature remained within the values which
would ensure evaporation, the pressure within the heat exchanger would increase and push the
gas towards the tank, bringing the system back into equilibrium.

OUR TECHNOLOGY COST SAVING

9. Page 9
REASONS WHY YOU SHOULD USE INDIRECT HEATING LPG VAPORIZERS
INDIRECT HEATING DIRECT HEATING
Moderate gas over heating Excess gas over heating
Low maintenance Frequent and periodical maintenance
Low cost standard spare parts High cost of spare parts
Wide range of capacity Limited range of capacity
Highly working reliability Loss of efficiency over time
No liquid inside of PGT vaporizer Liquid remain inside of the vaporizer in case
in case of system failure with of system failure
Electrical heater is a pull out one, so it In case of burns electric elements, you
can be replaced for itself: this also must buy another vaporizer
makes maintenance easier
Extremely safe Not always safe
Equipment can be changed to water No possibility to convert the equipment into version
supplied from boiler hot water version

REASONS WHY USE OUR ONLYONEUNIT SOLUTION – PLUG & PLAY
We design and produce ONLYONEUNIT solution, a system that implements the following controls
and devices:
- monitoring the state from liquid to gas, thanks to heat exchangers equipped by patented
control regulation valve
- monitoring of gas pressure reducing;
- metal cabinet complete of doors and air venting system;
- inlet&outlet piping ready to be connected to the onsite pipeline network
- Eexd light&electrical system (optional)
ADVANTAGES to use Pegoraro Gas Technologies ONLYONEUNIT solution
1) customized solution
2) ready to use package
3) quick connection inlet/outlet pipelines
4) all main monitoring&controls devices are on board
5) all devices are already protected by weather conditions thanks to the cabinet
6) the whole plant tested before delivery: no delay or setback in commissioning and total
warranty for the plant working
7) easy handling on site = reduced costs for installation
8) Very compact dimensions with great accessibility to equipment
9) Onlyone assembly certified in accordance to European Directive 2014/68UE PED

ADVANTAGES OF OUR LPG VAPORIZERS
GENERAL
• certified by relevant third party
• certified to be installed in the countries of Eurasian Economic Union
• 100% Made in Italy
• wide range of capacity
• simple and easy-to-conduct equipment
• some electrical preheated models can be shifted to boiler fed version
SAFETY
• control valve does not require electrical power supply
• control valve is normally closed: it stops the gas in case of failure
• control valve is equipped with rubber shutter that closes against a metallic seat: this
solution assures perfect sealing without leakage. Other manufacturers use instead a
metallic coupling which requires to be maintained clean
• control valve does not need manual reset
• control valve is installed external from the vaporizer: this allows maintenance or eventual
replacement
• in case of failure, no liquid LPG can be trapped inside the vaporizer. Avoids dangerous
overpressure
WORKING MAINTENANCE
• quick installations: control system does not require any electrical or pneumatic supply
• “onlyoneunit” versions available, with the whole equipments already mounted, wired up
and tested
• instruments and electrical heater are separately replaceable
• low maintenance and cheap spare parts
• pull-out nest of tube for allowing maintenance (Vapeg model)
