2 Product Description
The cooli g u it XRC-4501-OW is i te ded for the cooli g of a oil circuit. Oil circu-
lates betwee the cooli g u it a d the heat source. The oil is re-cooled by a water-
cooled heat excha ger. Cooli g hoses are co ected to the cooli g u it via screw
co ectio s (M 26 x 1.5). Coola t i let a d oil outlet are marked with symbols:
Inlet Oil:
O
↓
Outlet Oil:
O
↑
The oil flow is mo itored by a adjustable flow switch, the oil temperature by a
adjustable thermal switch. The sig als of the flow switch a d the thermal switch are
available at a pote tial free safety circuit. The oil pressure is limited by a adjustable
bypass valve.
The capacity of the cooli g u it depe ds o the temperature differe ce betwee the
Cooli g water temperature a d the oil outlet temperature.
