“VT-TMP” heating constant temperature bath Operating manual
This manual provides the information needed to operate heating constant temperature bath
“VT-TMP”.
INTRODUCTION
Intended use
Heating constant temperature bath is intended for standard test method for corrosiveness to
copper from petroleum products by copper strip test according to ASTM D130 and ISO 2160.
Appearance and parts names
3
Heating constant temperature bath “VT-TMP” consists of:
1 - Heating immersion circulator “M01”;
2 - Stainless steel bath tank with adapter for test thermometer 3.
Heating immersion circulator 1 includes a
rotary pump, a heater, a temperature sensor, an
output pipe for thermal fluid circulation and a
built-in cooling coil.
Place base 3 with vessels 4, which are in-
tended for running a copper strip test of petro-
leum products, or test tubes inserted in stand 6,
inside operating bath 5, located in the bath tank.

6The operating principle of the bath is
based on supporting a preset constant tempera-
ture of flowing thermal fluid in the bath tank and
providing a good temperature uniformity of the
operating bath. The circulation of thermal fluid
around test vessels is provided by the rotary
pump, which is located in heating immersion cir-
culator 1.
Maintaining of the preset temperature by means of heating is provided by immersion circula-
tor 1. To operate the instrument, read the “M01 Heating Immersion Circulator. Operating manual”.
When operating instrument with thermal fluid temperature close to ambient, it might be nec-
essary to provide the cooling by means of built-in coil.
Environmental Conditions
Indoor use only.
Ambient temperature: +10...+35 °C.
Air humidity: max. relative humidity 80 % for temperatures up to +31 °C,
Max. mains fluctuation of ±10 % are permissible.
Safety Recommendations
Avoid strikes to the housing, vibrations, damage to the operating element panel (keypad, dis-
play), and contamination.
Do not store the instrument in aggressive atmosphere.
Protect the instrument from contamination.
Only qualified personnel are authorized to perform configuration, installation, maintenance
and repairs of the circulator.
Routine operation can also be carried out by untrained personnel who should however be in-
structed by trained personnel.
! CAUTION: The instrument is not for use in explosive atmosphere.

USING THE HEATING CONSTANT TEMPERATURE BATH
! Before using bath circulator, carefully read the operating manual.
Preparation
Carefully select a spot for installing instrument with free
air access for the circulator ventilation. Make sure it is far away
from any kind of heat source.
Place the instrument on an even surface with a pad,
made of nonflammable material.
Install circulator 1 into the adapter on the bath cover 3.
Secure the circulator with screws 2.

! While setting up the circulator, supply cord should not be
connected to the power source.
Fill up the bath tank with thermal fluid through aperture
under bath cover 4. Level of thermal fluid should be 30 mm
lower than the cover level.
! When filling the bath up, do not spill any thermal fluid on
the front panel of the circulator.
Connect input 5 and output 8 connectors with hose 7
and secure it with the straps from our delivery package.
! If using polymethylsiloxane as a thermal fluid, utilizing of
silicone hose is prohibited.
Place stainless steel vessels on the base. If necessary,
remove the base and place the stand with test tubes directly
on the bath tank.

When operating instrument with thermal fluid tem-
perature close to ambient, it might be necessary to provide
the cooling by means of built-in coil. In order to do that, con-
nect thermostat to tap water supply with hoses, attached to
the coil connectors 6 and 9. The flow of the cooling water
must be even and slightly weak. The cooling is not necessary
if thermal fluid temperature is at least 15 °Сhigher than am-
bient temperature.
To operate the instrument, read the “M01 Heating
Immersion Circulator. Operating manual”.
