Compressors

GRAF Gastech offers compressor units with two different ranges of
suction pressure for biogas downstream of upgrading system and
injection into gas pipeline at discharge pressure up to 100 bar.

The range covers the most common capacities required in
the market. GRAF Gastech is also able to offer customized
solution for specific requests. Compressors are designed for
achieving high reliability and 8000h/year duty cycle.

Each component is designed in order to meet the highest quality
standards and to minimize the maintenance and production stops.

Compressor units are tested with natural gas and all parameters are
checked before every shipment. GRAF Gastech has built dedicated
areas for performing 5-hrs run test at the working pressure indicated
by the customer. During run test, equipment working parameters are
checked and testing data are recorded. This allows to be sure of the
correct operation of the system before delivery to the customer.
