The collector means accumulator-distributor. Many compressors are used to distribute suction gas and provide recycling of oil. The collector is an auxiliary component of cooling system collecting more than one pipe into one pipe or distributing one pipe to more than one pipe. They are made in a way to be suitable for pipe diameters accumulated in the cooling system. Number of inlet and diameters are determined according to number and type of compressor operating in the system. In case it is demanded, manufacture can be performed in different capacities and characteristics.
