Inquiry (采购产品): Injection Molder cooling cart I have a Pump Engineering Co Cooling cart for an injection molding machine. On the side of the unit is a name plate with your company's name and SO 01108 stamped on the side. The Injection molder is a 1980's vintage. Would it be possible to get a maintenance and operating manual for this unit? If not can you at least tell me what is the fluid that should be inside the unit, for example is it suppose to be 50/50 ethylene glycol. **** Hidden Message ***** David Berkheimer CO 80817 USA Company: RMB Products Title: Maintenance E-mail: dberkheimer@rmb.com **** Hidden Message ***** dberkheimer@rmb.com
