Technical data of the heating and cooling module
The pump carries the changed identification with the non insulating coupling
components and the higher temperature:
CE
II 2G c IIC T3 X
Description of the single symbols:
Equipment meets the requirements of the RL 94/9/EG
II
Equipment of the group of equipment II („Non-mining industry“)
2G
Equipment of the category 2, intended for the employment in zone
1 (explosion endangerment by inflammable gases, steams or
nebulas), can be used also in zone 2
c
As explosion prevention measure the ignition enclosure was
converted „constructional security“(c) according to EN 13463-5.
IIC
The equipment fulfills the requirements for the employment within
highly combustible ranges, within which the explosion
endangerment can be due to materials of the explosion group IIC
(like e.g. hydrocarbons).
