CoolForce 1 neither contains borax nor nitrites phosphates nor amines HV VY bloodred eA im 2 CoolForce 1 posseses excellent stability at high temperatures and prevents the formation of harmful deposits on hot metal surfaces at temperatures of up to 200 C at watt densities as high as about 40W cm 2 It thus helps to avoid overheating at heat transfer surfaces and the formation of deposits in the circuit and thus ensures consistently high thermal efficiency of the system Miscibility CoolForce 1 is miscible with all commercial antifreezes based on ethylene glycol If mixing of CoolForce 1 with other pro ducts is intended we recommend however to contact our department of application technique beforehand Application CoolForce 1 is added to water potable water quality with a maximum chloride content of 100 mg kg or demineralised water in concentrations of at least 20 percent by volume The protection against frost deteriorates if the content of Cool Force 1 exceeds 58 percent by volume Temperature stability Sustained temperatures higher than 140 C cause premature ageing of the heat transfer fluid but brief exposure to tem peratures higher than 140 up to 200 C can be tolerated if the liquid is subsequently cooled At temperatures above 200 C the heat transfer fluid commences to undergo chemical change with the result that the dependability of the installati on may be endangered A blanket of nitrog
