“DR60-Ethylene Series” is a special Ethylene gas regulator with the cylinder mounted. It is designed to maintain the temperature of gas at normal temperature by passing the whole flowed-in gas through the cylinder internals, for which we have Patent (Patent No. 146709). With this special function, DR60 Ethylene Series is very suitable to use the Ethylene gas having peculiar coldness very safely. They are designed and manufactured taking into consideration of the highest safety and easy operation. But, it is recommendable to use at a surrounding temperature of regulator over +8℃ considering the Ethylene’s peculiar coldness and for more efficient operation of the regulators.
