GL GL TUBE TYPE OIL COOLER SERIES
INTRODUCTION
This productis manufactured byour company thatcombining with theinternal and externalbase of advancedtechnology and craft. The material ofheat-exchange pipe, adoptedlow-rib finned redcopper pipe, usedthe structure oftransverse current breakerboard, turbulence boardand the advancedmanufacture craft ofmechanism expanding, hasthe features ofnovel structure, small dimension, light weightand well heat-exchangingeffect and soon.This product is anew type andhigh efficiency cooler,mainly used inlow-viscosity hydraulic and oilsystem to coolthe work oilto the specifiedtemperature. So itis an Ideal cooling facilitythat can bewidely used incooling the hydraulicequipment in the tradesuch as chemicalindustry, electric power,metallurgical industry, mine and lightindu 17.5 4-22 30
