Operation Method
Nybrine Freezing Temperature and Viscosity (reference data)
"Nybrine" is a brand name which Maruzen Chemicals developed. The main ingredients are good Ethylene Glycol and
Propylene Glycol. It is a heat transmittal medium which is well-considered for safety and rust prevention of the equipment
by adding various antiseptics.
