The BUCR series power unit tank oil coolers
are an oil-to-air heat exchangers. Coolers are designed to stabilize the oil temperature
and use an internal oil pump and slow spinning blower wheel to draw air through an
oversized cooler. This combination offers excellent cooling capacity with low noise.

Model BUCR-THERM1
Adjustable thermostat 85°F - 195°F with terminal box.
Included with BUCR series cooler
Built in wire terminal box
Switching point adjustable outside of wire terminal box
Temperature-feeler through hole in cover in oil
The thermostat can be used for switching a cooling circuit ON and OFF. The operating
temperature of the thermostat contact can be set from outside by means of a handwheel. The
sensor element is immersed into the oil through the drum lid. It is essential that the
sensor element is always immersed in the oil.
