The group PROFER GROUP
is exceptional in the offer complexity in the field of liquified petroleum gases use.
is a specialist in the field of:
- - purchase from direct sources (refineries)
- - supplying by street tank cars from warehouses all over the Czech Republic
- - construction and service of filling stations, their financing and operation
- - construction of energy sources (heating, steam production, cogeneration)
- - LPG and technical propane addition in order to increase its quality parametres (higher efficiency, reduced consupmtion, reduction of noxious substances influence)
PROFER GROUP is an innovator in the field of LPG use as an alternative energy source. What the others
only think of, the team of PROFER GROUP is realizing. We look into problems in order to find solutions
in favour of our customers. That is what makes PROFER GROUP exceptional in the LPG industry.

Propane and butane belong to a group of hydrocarbon gases with three or four atoms of carbon in
a molecule which are acquired during oil and natural gas processing. Liquified propane-butane
is colourless, easily volatile liquid of specific odour. At normal (atmospheric) pressure and
temperature it is a gaseous mixture, however at slightly increased pressure it becomes a liquid
state and the capacity decreases (approximately 260 times). This is the reason why it is possible
to store huge amount of calorific capacity in quite a small tank.
Propane-Butane is a mixture of in its name stated products (propane and butane). Propane and Butane
are non-toxic and if accidentally spilled, they evaporate and have no ground or water pollution hazards.
Emission levels of both products are comparable with natural gas and in some parametres they are better.
Propane and propane-butane can be stored in pressure tanks. Tanks are located outside of buildings above
the ground or underground. Depending on the consumption it is possible to install tanks of the capacity
from 2 m3 (mostly for houses) up to 250 m3. There exist storage tanks safety zones with regard to the tank size,
varying from 3 m (houses) to 100 m.
