Spark Resistant Interior (Acc. To Atex Guidelines)

The spark resistant combined laboratory refrigerators/deep freezers are specially designed for the orderly storage of chemicals, patterns, toxic materials and other flammable liquids at temperatures below freezing.

The spark resistant laboratory refrigerator/deep freezer is equipped with two completely separate cooling systems, so that two temperature ranges can be set independently (2 °C to 15 °C and -5 °C to -30 °C).

The appropriate regulations must be observed in other countries).

Showing the single result

Spark resistant combined refrigerator and deep freezer fulfils the guidelines for laboratories DGUV 213-850 and the Atex guidelines 94/9EG

Do you need a spark resistant combined refrigerator/deep freezer for your laboratory to safely store chemicals, flammable liquids or toxic materials? tritec® offers you the perfect solution! Our products are not only GMP-certified but also comply with the EU Directive 94/9/EC for equipment in potentially explosive atmospheres, and the guidelines for laboratories DGUV 213-850. These are laboratory guidelines that are intended to ensure safe working conditions. For example, there are no electrical ignition sources inside such a device. In our high-quality laboratory cooling and freezing combination, you store samples and materials at constant temperatures. A total of 361 litres are available for this purpose, distributed over two separate cooling systems. The refrigerator of the combination unit has a capacity of 254 litres and a temperature range of 3° to 16°. The deep freezer, on the other hand, covers a range from -9° to -30°. Two controls make it easy to operate and install the required settings on the spark resistant combined refrigerator/deep freezer.


Combined refrigerator/deep freezer for hazardous materials

The housing of the combined refrigerator/deep freezer consists of galvanised sheet steel, which has been sealed with an epoxy resin coating. In addition, the combination unit has an acid-resistant sealing strip. On the display of the temperature controller you can read off the actual value at any time and set the setpoint using the foil buttons. If deviations occur, these are indicated both optically and acoustically. When you open one of the two doors, a circulating air fan is automatically switched on. This prevents warm air from being sucked in, so that the set temperatures remain constant. For the upper refrigerator, we supply three glass drawers that are height-adjustable and can each carry 40 kilograms of weight. You also get three drawers for the freezer compartment. Of course, you have the opportunity to have a look at all the technical details for the spark resistant combined refrigerator/deep freezer at your leisure. You will find a data sheet for each of our laboratory units on the corresponding page, so that you can compare different models with each other.
