CAUTION:
The range of heater
circulators described here are not to be
used in conjunction with
oil
as Pyrolysis
(Chemical Decomposition by Heat) will
occur.
WARNING:
Do not use flammable
solvents or combustible materials as fire
or explosion may occur. This equipment
uses components which may be a
source of ignition.
FUNCTION
To provide an accurate controlled temperature b30
°
C to +100
°
C.
Model TU-1: a5° to +100°C.
PRINCIPLE OF OPERATION
The
analogue
range of Heater Circulators are designed to be compact, light and
efficient heater circulators of water. They are ideally suited to Laboratory Bath
applications where minimal spacial variation is tolerated.
The analogue controller, and long shaft (240 Volt) electric motor are located within
the controls enclosure. Below is suspended, the circulating pump housing, heating
element and sensor.
The desired operating temperature is set at the control. A signal from the sensor is
monitored at the controller. The resultant output switches power to the heating
element.
Energy from the element gently heats the water, the amount of energy is determined
by the sensor.
The circulating pump runs continuously maintaining close temporal uniformity
throughout the bath.
The heater circulator may be supported on a fabricated bridge (standard with each
Thermoline Scientific circulating water bath) or from an
optional
bath to heater
bracket/clamp.
Note:
When working at temperatures above 60°C a suitable bath cover (lid) should
be used to maintain the operating environment and minimise energy loss.
PERFORMANCE
The operating range for this equipment is +30°C to +100
°
C Model TU-1 is ambient
+5°C to +100°C, Temporal Stability 0.5°C.
MAXIMUM TEMPERATURE
For this product is +100
°
C.
