Latching during the risk of arcing

Latching during the risk of arcing

Hold the door in place even if there is an accident

Vision Outside HEAVY-DUTY is designed to be tested in low- and medium voltage applications with risk for electric arc explosions. The Vision HEAVY-DUTY latching system makes it possible to operate heavy-duty locking points along several sides of a door. Space the heavy-duty locking points according to your needs, and add Vision guide points to simplify closing the door. Add a re-directional corner for each additional door side you want the locking points on.

When using the latching system to prevent accidents during an electric arc (explosion-proof use), the whole application (enclosure and latching system) must be tested and approved by appropriate authorities to receive a certificate for use.


The advantages with Vision HEAVY-DUTY:

  • Heavy-duty locking points (Ø 8 mm stainless steel) insures maximum protection so that door will stay on the enclosure in case of an accident.
  • The Vision guide-blocks guide the door when closing and positions the door in the right position prior to latching.
  • The corner control mechanism allows you to place locking points along any side of the door. You can even place locking points between the hinges!
  • The latching mechanism is placed outside the sealed door area, resulting in a ”clean” door design with no cut-outs in critical areas of the door.
  • System can be manouvered with any of our Vision-styled handles.
  • As door is latched - it is fixed in all dimensions (X, Y and Z) creating a vault-type latching performance, second to none.
  • Direct load transfer from frame to door i.e. no oscillations from load transfer via rods.
  • Unlike other systems on the market, this system operates with door allocation prior to gasket compression, and finally the heavy-duty locking points are activated. No shearing or side loads on the gasket means better sealing properties and longer gasket life.
  • Versatile and flexible means that the Vision system is capable of filling all your enclosure latching needs. Single system designation means higher production efficiency and less supply chain costs.
