Assembly for compressing gas having a housing comprising coolers in a central section, method for cooling, and use of such an assembly

An assembly for compressing a gas, containing a housing that comprises a plurality of components, the plurality of components containing at least:

• a first liquid-injected element for compressing gas;
• a first motor for driving the first liquid-injected element;
• a second liquid-injected element for compressing gas;
• a second motor for driving the second liquid-injected element;
• a first liquid separator in fluid communication with a gas outlet of the first liquid-injected element for the gas compressed by the first liquid-injected element;
• a second liquid separator in fluid communication with a gas outlet of the second liquid-injected element for the gas compressed by the second liquid-injected element;
• the plurality of components being distributed across a first section and a second section of the housing, and a central section also being provided in the housing, which central section separates the first section and the second section from each other, the central section containing:
• a first cooler for cooling a first liquid in a first liquid injection line for the first liquid-injected element in fluid communication with a liquid outlet of the first liquid separator;
• a second cooler for cooling a second liquid in a second liquid injection line for the second liquid-injected element in fluid communication with a liquid outlet of the second liquid separator,
• wherein the first cooler and the second cooler each have one or more fans to force a cooling air flow through the first cooler and second cooler in a same direction, each cooling air flow being provided to flow from the first section to the second section.
