Secuflow

More Safety, Economy and Comfort Than Ever

The highly innovative Secuflow fume cupboard with supportive flow technology for optimum flow regulation requires an extract air volume of only 270 m3/h/lfm while operating safely. This significantly reduced energy consumption makes laboratory operations even more economical.

With the Secuflow fume cupboard, supportive air is systematically directed into the internal workspace from the aerodynamically designed sill on the side panel and along the worktop. This prevents turbulences and perfectly stabilises the inflow air.

The Secuflow fume cupboard is a perfectly coherent product which has passed all final EN 14175 and ASHRAE 110/1995 tests with excellent results.

Secuflow EN7

The New Fume Cupboard for High Thermal Loads & Working with Acids

The new standard EN 14175-7:2012 regulates fume cupboards for special application with high thermal load and/or acidic load. The use of these special purpose fume cupboards instead of general purpose fume cupboards is usually the result of a risk assessment.

The standard is applicable for the following special purpose fume cupboards:

  • Fume cupboards for high thermal loads
  • Fume cupboards for high thermal loads in combination with acid digestions
  • Fume cupboards for handling of perchloric acid
  • Fume cupboards for handling of hydrofluoric acid

Additional objectives that are formulated in section 7 go beyond the safety and performance targets defined in EN 14175-2, for example:

Requirements for materials
In fume cupboards for high thermal loads, the materials used must be able to meet the resulting demands. The materials must be chemically resistant to acids and acidic vapours and resistant to thermal deformation at the working temperatures.

Requirements on the cleanability
The construction of the fume cupboard must secure the necessary access to all air flow parts for cleaning purposes.

Requirements on the air flow and the monitoring
Impacts on the air current, caused by thermal loads and installed heating appliances, for example, must be taken into account and limited. In addition to the fume cupboard function display with the acoustic and optical alarm, fume cupboards for high thermal loads must be equipped with a temperature sensor that will trigger an alarm when the maximum temperature is reached.

While the previous standard series EN 14175 defines exclusively isothermal conditions in the fume cupboard, the newly issued part 7 offers the opportunity to evaluate the safety of fume cupboards on incidence of high thermal loads. This closes a significant gap, as working with heat sources in the fume cupboard is part of the everyday routine work in many laboratories.
