MISE EN GARDE: Assurez-vous que l'air de drainage circule lorsque le four est en marche. Le non

respect de cette précaution pourrait provoquer des dégâts sur les composants du four. La conduite

de drainage se raccorde à l'arrière de l'ARES-G2, au port étiqueté DRAINAGE DU FOUR.

The oven is a forced convection environmental chamber that encloses the sample. Mounted in the oven are

two resistive heaters, which are used to control the temperature of the gas flowing through them. During

testing at or above ambient temperature, either air or nitrogen gas may be input to the heaters. If test tem-

peratures must be extended to below ambient, the input to the heaters must be evaporated liquid nitrogen

(LN2) supplied by the optional cryogenic LN2 Cooler (or very cold gas supplied by the optional Chiller).

Figure 11 ARES-G2 Forced Convection Oven.

Table 1: FCO Specifications

The forced convection oven has two forced gas gun heaters with counter-rotating air flow for a wide tem-

perature range (ambient to 600°C*) and maximum temperature stability. If you plan to sustain tempera-

tures above 450°C, the use of the heat shield is required. If you will be running at temperatures below

ambient, either the optional LN2 cooler (operation to –150°C) or the ACS-3 chiller (operation to –100°C)

can be used to extend the operational range of the oven. The forced convection oven is recommended for

polymer melts and solids, and can accommodate Cone and Plate, Parallel Plate, Torsion Rectangular and

Torsion Cylindrical geometries, as well as EVF and SER2.

NOTE: The 600°C temperature testing is limited to two hours. The transducer may shut down if it is run

for a longer time period.
