Techne supply a range of liquid baths from 8 to 48 litre which can be fitted with any of the TE-10 or TU-20
thermoregulators. The B-8, B-12, B-18, and B-26 bath inner containers are manufactured from stainless
steel for maximum corrosion resistance and are deep drawn with large easy clean corner radii. The B-48
inner is also manufactured from stainless steel but is of welded construction.

DEscrIpTIOn

The thermoregulators are designed to fit all standard laboratory baths, especially Techne baths. They will
heat, circulate and safely control the temperature of the liquid in the bath within precise limits. In a
suitable bath, the TE-10 or TU-20 will control the temperature of the liquid within the range -40°C to
250°C (see the specifications for details). However, temperatures from -40°C to 5°C above ambient
require an additional cooling system such as a Techne Flow Cooler.
The instrument consists of the following main parts:
• The pump assembly and base moulding in PPS plastic. The pump can circulate liquid externally under
pressure via its support tubes.
• A heater assembly in 316 Stainless Steel.
• A base plate made from stainless steel to which are mounted the motor, over-temperature cut-out,
mains switch, fuse holder and PCB assembly.
• A cover made from Noryl plastic which is fitted over the main controls.
In the TE-10A, bath temperature is monitored and controlled by a thermistor in conjunction with a
proportional controller.
In the TE-10D and the TU-20D, bath temperature is monitored and controlled by a PRT in conjunction
with a 3 term controller.
Protection in all the units is provided by means of an adjustable over-temperature cut-out. The pump
motor and the transformer are also fitted with thermal fuses.
A portable clamp or a bridge piece are available as alternative ways of fixing the thermoregulator to the
bath.
