Air-Cooled Furnace System
Our Air-Cooled Vacuum furnace cooling system utilize the Aqua-Vent Air Cooled Heat Exchanger in combination with the CLEANLOOP Pump Station technology to reject heat from the furnace directly into the ambient air.
With the correct inhibited glycol/water concentration, our system will virtually eliminate scale buildup and corrosion in your furnace.
The attached diagram illustrates the principle of operation of the air-cooled system.
Coolant is pumped from a sealed reservoir through the air cooled heat exchanger that use high efficiency propeller fans to draw air over a large finned tube radiator. Heat is rejected to the atmosphere. From the air-coolers, the coolant is supplied to the vacuum furnace and returned to the reservoir, completing the closed loop. The system is sized to supply coolant (typically ethylene or propylene glycol) to the furnace at a temperature that is within 10°F of ambient air. It is very important to utilize the correct concentration of glycol for freeze-protection.
