Device for compressing a gas and method of assembling such device

Method of assembling a device for compressing a gas, which method comprises the following steps:

• providing a first element (3a) for compressing the gas and a second element (3b) for compressing the gas;
• providing a drive (4a, 4b) for the elements (3a, 3b);
• providing a cooler (8) for the compressed gas;
• providing an oil reservoir (6a, 6b) for each of the elements (3a, 3b), namely a first oil reservoir (6a) for the first element (3a) and a second oil reservoir (6b) for the second element (3b),
• characterized in that the method further comprises the following steps:
• providing a separate drive (4a, 4b) for each element (3a, 3b), namely a first drive (4a) for the first element (3a) and a second drive (4b) for the second element (3b);
• placing each element (3a, 3b) and the corresponding drive (4a, 4b) one behind the other, viewed in an axial direction (X-X′,Y-Y′) of this element (3a, 3b), wherein the axial directions (X-X′,Y-Y′) of both elements (3a, 3b) extend parallel to and spaced apart from each other and such that the elements (3a, 3b) and the drives (4a, 4b) are adjacent to each other;
• placing the device (1) on a base (7), wherein each oil reservoir (6a, 6b) is arranged between one or more of the drives (4a, 4b) or elements (3a, 3b), on the one hand, and the base (7), on the other hand;
• wherein said cooler (8) is arranged between one or more of the elements (3a, 3b) or drives (4a, 4b), on the one hand, and the base (7), on the other hand;
• and wherein the cooler (8) is arranged adjacent to the oil reservoirs (6a, 6b) with respect to the base (7), wherein the cooler (8) extends with its axial direction (Z-Z′) transverse to the axial direction (X-X′, Y-Y′) of the elements (3a, 3b).
