This is the industry’s first R1234yf non-Freon coolant compatible oil chiller. With a global warming potential of less than 1 and ozone depletion potential of 0, this coolant is an environmentally-friendly alternative to Freon. And, of course, these oil chillers are exempt from the Fluorocarbon Emissions Law. VSC-N Series oil chillers greatly reduce maintenance time and labor because they do not need a basic inspection every three months. What’s more, they reduce costs associated with collecting Freon when discarding and dismantling equipment.

*Cooling capacity, current consumption, and power consumption values are based on a 35ºC room temperature and 35ºC oil temperature (ISO VG5).
*Do not use machining fluids, grinding fluids, water and water soluble liquids, pharmaceutical and food product liquids, gasoline, kerosene, thinner and other highly volatile, low-lubricant fluids, or flame-retardant hydraulic oil.
Temperature control precision is based on the temperature gage reading under constant load.
* Maintain power supply voltage within ±10% of rated voltage.
