Food factory automatic doors: hygienic hands-free pedestrian entrances, change-room doors and sealed sliding doors for food production and processing plants.
Laboratory Automatic Doors: Sealed, Hands-Free and Controlled
Laboratory automatic doors keep air pressure, cleanliness and access under control, while letting people with gloved hands and trolleys move through without touching anything.
For specifications, sizes and a project quote, see our commercial automatic doors page. This guide explains what laboratory automatic doors need to do, which door suits each entrance, how they are installed and serviced, and what they cost. We do commercial pedestrian entrances only: no garage doors, gates, roller shutters or private homes.
What laboratory automatic doors need to do
Every entrance is different, but laboratory automatic doors share the same six requirements.
Air pressure
Hermetic sliding doors press against a seal when closed, holding the pressure differences that labs and cleanrooms rely on.
Hands-free
Gloved hands should not touch door handles. Sensors, foot sensors or elbow switches open the door.
Interlocked airlocks
Airlocks use two doors that cannot open at the same time, protecting the clean area.
Access control
Only trained staff may enter some labs, so doors are linked to card or biometric access and logged.
Cleanable surfaces
Smooth, flush leaves without dust traps are easy to clean and disinfect.
Trolleys and equipment
Wide openings and slow, safe closing let trolleys and equipment pass.
Which door suits each laboratory entrance
These are the starting points we use for laboratory automatic doors. Every doorway is confirmed on site.
| Entrance | What we usually specify |
|---|---|
| Cleanroom entry | Hermetic sliding door |
| Airlock | Interlocked pair |
| General lab | Hands-free sliding |
| Corridor | Swing with push button |
| Store room | Sliding with access control |
The operators behind laboratory automatic doors
Most laboratory automatic doors we install run on one of two operators, both imported and assembled at our Laser Park base in Roodepoort and tested to one million operating cycles: the MC-125 automatic sliding door, from R27 590 excluding VAT, and the MCW-100 swing door operator, from R15 900 excluding VAT. Both carry 24 months on the operator.
To see how the drive works, read our automatic sliding door mechanism guide.
Common faults on laboratory automatic doors
Worn hermetic seals, interlock faults, and sensors affected by cleaning chemicals. Most of these start as wear that a six-monthly service would have caught. See automatic door repairs.
Installing laboratory automatic doors
Every project starts with photographs and a survey of the opening, the header, the floor, the power supply and the access-control connection. We confirm the door type, leaves, glass, sensors and locking in writing, install with our own team (usually in a day for a standard entrance), commission the speeds, sensors and locking for the people who use the door, and hand over a written record of the settings. See automatic door installation.
On a new building, involve us before the shopfront is ordered so the header, power and cabling are right first time. On an existing building, sound leaves can often be reused with a new operator, which costs a fraction of a new entrance. See automatic door CAD drawings.
Servicing laboratory automatic doors
Average doors are serviced every six months; busy entrances more often, based on the cycle count recorded at each visit. Every service checks the track, rollers, belt, motor and controller, tests the sensors, lock and battery, sets the speeds and forces and ends with a written record. Several doors or branches can sit under one service level agreement.
Power cuts, fire and safety
Every entrance gets a defined behaviour for a power failure and a fire alarm: open and stay open, close and lock, or keep running on battery backup, agreed with the building and its fire strategy. Safety sensors stop or reverse the door before it touches anyone and are tested on every visit; glazing is safety glass as SANS 10400-N requires. See automatic doors and load shedding and automatic door safety requirements.
What laboratory automatic doors cost
The MC-125 sliding door operator starts from R27 590 excluding VAT and the MCW-100 swing door operator from R15 900 excluding VAT. The installed price of laboratory automatic doors depends on the leaves, glass, header, sensors, locking and access control, and every site gets a written quotation. Planned servicing costs far less over the life of a door than emergency call-outs. See automatic door prices.

Seal checks
Hermetic seals wear and must be checked on every service. A worn seal lets pressure leak and contaminants in, so it is replaced before it fails.
Validation records
Labs and pharmaceutical sites need records for validation and audits. We provide service reports that show what was checked on every door.
Laboratory automatic doors in universities and hospitals
University and hospital labs share corridors with offices and wards, so lab doors combine sealing with access control and accessible routes.
Cleaning chemicals
Disinfectants can damage sensors and seals. We agree a cleaning method with the lab so the doors are cleaned properly without harming them.
Planning shutdowns
Work on clean areas is planned for scheduled shutdowns, with the area re-cleaned afterwards according to the lab’s procedure.
Health and safety on site
Every job starts with a site induction where the building requires one and a safe-work method that covers barricading the doorway, working at height on the header, isolating the power and keeping an alternative route open. Our technicians carry their own protective equipment, follow the site’s own hygiene and access rules, and leave the work area clean.
One team for the life of the door
We design, supply, install and service laboratory automatic doors with one team, so there is one point of contact from the survey to the last service visit. If laboratory automatic doors ever fail, the people who installed them are the people who fix them.
Sliding, swing or revolving?
Sliding doors move the most people and never swing into anyone, so they suit most main entrances. Swing doors suit narrow openings, corridors and existing hinged doors. Revolving doors keep wind and heat loss out of tall lobbies but always need a swing door beside them for wheelchairs and goods. For laboratory automatic doors, the main entrance is usually sliding and the internal doors swing. See sliding vs swing door.
Safety sensors explained
Activation sensors, usually microwave radar, open the door when someone approaches. Safety sensors, usually active infrared, watch the threshold and the path of the leaves so the door cannot close on someone standing still. Light curtains in the posts add a vertical safety field on busy or sensitive entrances. All of them are set on site and tested with a test body on every service.
The first year after installation
In the first months the building learns how the door behaves, and we often fine-tune speeds and sensor fields after the first busy weeks. The first service, normally at six months, records the cycle count so the service interval for laboratory automatic doors can be set from real use rather than guesswork.
Three common myths
“Automatic doors waste energy”: a well-set door closes faster than people close a manual one. “They are only for big buildings”: a single swing operator can automate a small practice door. “Any electrician can fix them”: safety settings, forces and sensors need a trained technician and the right parts.
Gauteng conditions
Gauteng brings its own challenges for laboratory automatic doors: summer afternoon storms with hail, wind and driving rain; dry, dusty winters that grind into tracks and rollers; lightning that can damage electronics; and load shedding that can stop a door at the worst moment. We answer each one with the specification: laminated or toughened safety glass, sensors set to ignore wind-blown debris, brushes and seals against dust, surge protection where lightning is common and battery backup on every entrance that must keep working. The service interval is then set from the conditions at each site, not from a fixed calendar.
A typical project, step by step
The client sends photographs of the entrance and tells us how busy it is. A technician surveys the opening, the header, the floor and the power and access-control connections. We confirm the door type, leaves, glass, sensors and locking in writing with a price and lead time. On the agreed day our team installs the operator and leaves, commissions the speeds, sensors and lock, tests the power-failure and fire behaviour with the building and hands over a written record. The first service is booked six months later. This is how every project for laboratory automatic doors runs, large or small.
Access control and security
Doors can be linked to card, tag, biometric, keypad or intercom readers, to timers for trading hours and to the alarm. Two doors can be interlocked where screening is needed, and the lock is set to release on the fire signal where the door is an escape route. See automatic door access control.
Accessible entrances
An automatic door is the simplest way to make an entrance usable for wheelchair users, parents with prams and people carrying goods. Clear width, opening and closing speeds, hold-open time and push buttons are set on site for the people who use the door. See automatic doors for disabled access.
Energy and comfort
A door that closes promptly keeps air-conditioning and heating inside. Hold-open times and sensor fields are set so the door opens for people coming in and out, not for passers-by or wind-blown leaves, and an airlock or revolving door is considered where wind is a problem.
Working in occupied buildings
Most of our work happens in buildings that stay open. We barricade the doorway, keep an alternative entrance open, work outside peak hours where possible and leave the site clean. Every visit starts with a safe-work method for that building.
What you receive after every visit
A written report of what was found and done, the parts used, the settings left on the door, the cycle count, anything that still needs attention and the date of the next visit.
Planning your budget
Budget for three things: the installation or repair itself, any parts or new equipment, and an ongoing service plan. Where several entrances need work, it can be phased over months, starting with the doors that matter most to safety and security. Planned servicing of laboratory automatic doors costs far less over their life than emergency call-outs.
Spare parts we hold
We keep the parts that wear first at our Laser Park workshop: belts, rollers and carriages, sensors, locks, batteries and controllers for the MC-125 and MCW-100, and common parts for other makes, so most faults are fixed on the first visit. See automatic door spare parts.
Modernising older entrances
When an old operator keeps failing or its parts are no longer made, a new MC-125 or MCW-100 can usually be fitted to the existing leaves, glass and frame. This costs a fraction of a new entrance and comes with 24 months on the new operator. See automatic door modernisation.
Why choose MC Automations
- Our own operators: the MC-125 and MCW-100 are imported and assembled at Laser Park.
- Our own technicians: we never sub-contract installation, servicing or repairs.
- Any brand: we service and repair other manufacturers’ doors too.
- Spares in Gauteng: common parts are held at our Laser Park workshop.
- Written records: every visit ends with a report.
- Warranty: 24 months on new MC operators.
Getting the best from your entrance
Keep the floor guide and the area in front of the sensors clear, do not prop the door open or block it with stock, and ask cleaners not to spray water onto the sensors and header. Report noises, hesitation and doors that reopen for no reason early, because these are the first signs of wear. Know where the program switch is and what each mode does, so staff can set the door to open, closed, exit-only or night mode when needed.

Questions to ask before you choose a contractor
Ask who will install and service the doors, whether spares for your make are held locally, how quickly they attend a breakdown, whether you get a written report after every visit, what warranty applies to new operators, and how the power-failure and fire behaviour of each door will be set and recorded. A supplier who answers all of this in writing is one you can rely on for the life of the entrance.
