DTC-300 Technical Specifications

Item/Area

Specifications

Dimensions

Depth 71 cm (28 in)

Width 64 cm (25 in)

Height 94 cm (37 in)

Weight 

44.5 kg (98 lbs)

Power

ab

a. This instrument is supplied with a power cord approximately 2.4 m (7.75 ft) long. The 220V instrument 

power cord comes supplied with a USA NEMA 6-15P style plug; the 110V instrument power cord comes 
supplied with a USA NEMA 5–15P style plug. The TA Representative installing the instrument will pro-
vide the appropriate power cable for the geographical location where the instrument is being installed. 
Ensure that the mains assigned do not also supply power to noise generating equipment nearby, such as 
motors, welders, transformers, etc.

100–120V (for 110V instrument) or 200–240 VAC (for 220V instru-
ment)
50/60 Hz
10A max current supply
Supply voltages lower than indicated limit may result in a degrada-
tion of performance.

Fuse Type

2X T 10A L 250V

Operating Environmental Conditions

Temperature: 15 to 35°C

Relative humidity: 5 to 80% (non-condensing)

Maximum Altitude 2000 m (6560 ft)
Locate instrument in a ventilated space (hood, etc.) if noxious gases 
or vapors are generated during the heating of samples.
The degree of protection for this instrument according to EN 60529 
is IP20.

Purge Gas System Requirements

Nitrogen Purge Gas

c

1.5 psi (0.1 bar) nitrogen gas furnace flush is required for operating 

at temperatures below 20°C.

Pneumatic System Requirements

Compressed Air/Inert Gas

d

Maximum inlet pressure to the instrument: 60 psi (4.1 bar)
Typical operating pressure: 40 psi (2.8 bar). The flow rate is less 

than 1 L/day. Compressed inert gas or air from a gas cylinder may 

be used. A proper gas cylinder pressure regulator/reducing regulator 

is required.

Cooling System Requirements

Chiller/Circulator or Cooling Water and Drain

e

Permissible coolant temperatures are between -40 and 20°C, 
depending upon testing considerations. Excessively cold water may 
result in “sweating” and possible corrosion of cooled metal surfaces. 
A nitrogen furnace cavity “flush” is required for sub-ambient opera-
tion. Warm water may not permit required cooling and stack tem-
perature gradients during testing.
