4.9 Options
The options installed in the device are to be recognized by a label next to the type designation
plate.
4.9.1 Option enlarged temperature range to 150 °C
Only at T 7000 (W) and T 10000 (W)!
The device is modified so that the upper limit of the working temperature range is expanded from
120 °C to 150 °C.
An additional fan is built in at the back side. Do not close the aspirating hole!
In particular it is to be noted that with temperatures exceeding 120 °C metal tubing
is used!
4.9.2 Option high-power pump
For devices T 1200 (W) – T 4600 (W)!
A high-power 2-stage pump with maximum values 5.5 bar/40 L/min is installed. Pump
characteristics ( Section 9 Technical Data).
The units T 1200 – T 2200 W have a larger overall height ( Section 9 Technical Data). The
cooling capacity is reduced by approx. 200 W.
4.9.3 Option flow control instrument
In the return line for the heat transfer a paddle flow control instrument is installed. The contact is
connected to the flanged 3 pole plug.
The contact closes at Q > 5 L/min with T 1200 – T 4600 W and
Q > approx.10 L/min with T 7000 – T 10000 W.
View on flange plug (Front) or solder side coupler
socket.
Maximum contact load 30 V; 1 A.
Use shielded lines.
Connect shielding with connector housing.
Cover unused plug connections with protecting caps!
Coupler socket Cat. No. EQD 047
4.9.4 Option low-pressure pump
Only for devices T 1200 (W) and T 2200 (W)!
This is a 2-stage radial disc pump with a maximum pressure of 1 bar and a maximum pump output/
flow rate of 30 L/min. This pump has a smaller noise level and in most cases can be used to
temper glass instruments. Pump characteristics ( Section 9 Technical Data).
