Spark resistant laboratory deep freezers with static cooling
Interior in spark resistant design (according to ATEX and DGUV 213-850 directives)
The tritec® spark resistant laboratory deep freezers are – depending on the model – controlled by a touchscreen temperature regulator with the possibility to retrieve all temperature relevant data via USB or Ethernet. For safety, alteration of the parameter and acknowledgement of alarms are only possible after entering a password.
In the housing of the controller, all relevant components are built in, to operate the cabinet. This “Box System”, and simple plug-in connections to the electrical supply lines, allow a service friendly exchange, if required.
