Introduction

The markus M5 hygienic sliding doors has been specifically designed for the use in the medical and pharmaceutical industries. 

There are many applications for these doors including clean room, laboratories, operating theatres, X-ray rooms (with lead lining within the door blade).  Also any other area requiring a clean, hygienic well sealing door.

How it works

The success of the door is a result of the hermetically sealing system.  The door blade is suspended from an overhead track.  As the door closes, it drops through an angle of 45˚ inwards and downwards.  The rubber gasket seals the door positively against the frame and the floor.

Door Frame

Envirodoor supply a sealing frame manufactured from satin anodised aluminium profiles or stainless steel which is designed to fit our clients sub-frame.

The sealing frame is fixed by means of screws which are concealed by a self-adhesive cover strip.

As an option we can offer a complete reveal plate system, designed to cloak the door opening on both sides.  The system comprises of a lining faced with plastic laminate (to match or contrast the door blade) held in position by the aluminium sealing frame to both sides of the opening.  This system can be designed to suit any wall thickness and gives an excellent aesthetic appearance.

Door Track

The door track is manufactured from a satin anodised extruded aluminium section.  The door is hung on two nylon running sealed-for-life roller bearings which drop the door through 45˚ on closing.  This pushes the door blade down towards the floor and in towards the door frame.  The track is completely covered by an aluminium or stainless steel canopy with a sloping top to prevent the build-up of dust.

Door Blade

The door blade is a single leaf construction comprising of a 41mm thick solid core faced with HPL plastic laminate on both sides (client’s choice of colour).  The door blade is encapsulated in a satin anodised extruded aluminium framework giving an overall thickness of 56mm.  at the base of the door there is an inverted “V” profile which not only guides the door over floor mounted cams but also protects the door face from trolley damage.

Vision Panels

Vision panels are available in a variety of shapes, sizes and configurations including single glazed laminated glass and double glazed flush units. They can however incorporate all types of glass and meet any requirements.

Sealing

A special tubular rubber seal is fixed within the aluminium frame to three sides of the door, whilst a flat rubber gasket is fitted to the underside of the door blade to seal against the floor, without the need for a threshold.

Manual Operation

As standard, the door is supplied with a satin anodised aluminium lever handle to both sides of the door.  Since the door utilises low friction, smooth running nylon rubber bearings, it can be opened and closed with minimum effort.

The following options are available:

  • Lead lining to the door and reveals for use in the X-ray areas
  • Locking to one or both sides
  • Sliding hatches or integral venetian blinds to vision panels
  • Sound reducing options including 27dB, 37dB and 43dB
  • Moisture resisting panels
  • Other types of laminate

Automation

Should it be required, the door can also be supplied with a low noise, microprocessor controlled electric door operator if required.  These automated variants feature a number of extra safety related features. 

As standard, the door is fitted with a photocell safety device which, if interrupted will not permit the door to close.

The electric door operator is sensitive to any obstruction to movement and will automatically stop and reverse should it encounter resistance. 

The microprocessor control continually monitors the position, direction of movement and speed of the door.  If any failure is detected, the control will indicate the nature of the failure by means of a service code.

The door track and blade have also been designed specifically to minimise the possibility of trapped fingers.

The following functions can easily be adjusted on site:

  • Opening/closing speed
  • Slow speed
  • Timer closing (0-60 seconds)

The operator can be activated by any of the following:

  • Kick switch
  • Elbow switch
  • Pull switch
  • Key switch
  • Radar
  • Active/passive infra-red
  • Remote control
