Hydraulic Compressors:
our Idro side
Our compressor units feature hydrostatic transmission.
The heart of the compressor are cylinders in single or twin configuration.
A steel rod connects the oil piston with the two gas pistons.
The only moving part is the connecting rod
It is a simple structure. The pressure of the oil drives the cylinder
Cooling system
Idro Meccanica compressors are water-cooled. The gas and oil are cooled by heat exchangers while the gas cylinders have a cooling jacket. The cooling circuit is completed with a radiator and a circulation pump.
maintenance
Installation and maintenance: what you need to know
The compression units are supplied mounted on a steel frame.
No foundations are required: the units can be placed directly on the existing baseplate.
The gas cylinders are not lubricated and their inner surface is chrome-plated.
The inlet and outlet valves of each compressor stage are maintenance-free: they do not require any check.
The parts subject to wear are the seals:
| Seals | Type | Life-cycle |
|---|---|---|
| gas side | Made of special PTFE (Teflon) self-lubricating compound | ~ 5000 running hours |
| oil side | hydraulic type | ~ 10.000 running hours |

Safety
Safety
All electrical apparatus on the compressor are designed to be used in a Z2 (Z1 upon request) hazardous area.
The electric motors are explosion-proof and all instruments are intrinsically safe fed.
The units are not equipped with venting lines. The compressor remains pressurised at all times.
Each compressor is complete with everything necessary for smooth and safe operation.
Three families - unlimited customisation possibilities
The great flexibility of Idro Meccanica compressors allows us to customise the entire system according to the customer's requirements. We choose the best solution in terms of efficiency and performance with highly competitive OPEX and CAPEX.
