Welcome To Idro Meccanica

Antonio Gozzi founded Idro Meccanica at the end of the ‘60s. He started the production of natural gas compressor and boosters based on a simple hydrostatic transmission. In 1966 we produced our first compressor.
During the first years the company expanded and developed different models, several covered by international patents, to meet the needs of the market.
Nowadays Idro Meccanica have produced more than 1500 compressors for natural gas, nitrogen, hydrogen and hydrogen/methane blends.


Idro Meccanica compressors are hydraulically driven. The oil and the gas sections are separated by a short single-compartment distance piece vented to the atmosphere. The vent lines for oil and gas could be collected and checked from time to time to control the status of the seals. The gas section is non-lubricated and due to the separation and the double seals the oil carry-over is virtually none.

The flexibility of the hydraulic system helps in having compressors and boosters that could accept a wide range of inlet pressures. Some of our units could also be used as compressor/boosters to fill and then intake gas from a high-pressure storage in order to achieve high flow-rate in direct fill.
The booster compressor are also the most suitable solution for daughter refuelling stations as they do not need to reduce the pressure from the mobile storages being able to accept a wide inlet pressure range, e.g. from 250 down to 3 barg.

Idro Meccanica compressors could have a maximum of five stages in one cylinder. The best-sold models are two and three stage compressors/boosters.

Most of the units could also be supplied in twin version with two compressors assembled on the same frame in order to reduce installation space. The twin solution could also be used with two different models in order to combine a booster with a low-pressure compressor.

The selection of the correct model is usually carried-out together with the potential customer taking into consideration the type of gas, available inlet pressure, required outlet pressure and rate of flow.
Most of the units could be tailored on the customers’ needs with just small modifications from our main PED certified standard models (more than 50).
