Novosprint High Speed Doors for Hygienic Environments

NOVOSPRINT high-speed doors allow traffic to move rapidly and safely. The sideways opening action of the two leaves of the door halves the opening time, and in contrast to vertically opening systems the user immediately has the entire height of the passage available. This avoids the risk of a collision with the door or of it landing on people or goods.

The NOVOSPRINT high-speed door reaches an opening speed of up to 5 m/s which is ideal for fast logistic processes, forklift traffic and air locks.

The clean solution

Whether it is used in the pharmaceutical industry, food industry or healthcare sector – the range of features available means that the NOVOSPRINT is able to fulfil all specific regulations in terms of cleanliness, freedom of pores, food safety and many other hygiene requirements.

In compliance with regulations, all tangible parts are made of nonporous and corrosion-resistant material, such as stainless steel and plastics.

Due to the lateral opening of the door, the closing edge does not touch the floor. Therefore, there is no risk of dirt particles or moisture dropping onto the goods.

The contactless switch detects approach at an adjustable distance of 10 to 50 cm. This hygienic solution is the ideal alternative to manual devices.




  • All major components are available in stainless steel.
  • Easy cleaning due to flat surfaces.
  • Easy disassembly of the casing makes cleaning and disinfecting easy.
  • Horizontal opening prevents dirt from being carried away from the floor by the under rubber and can fall on the products when opened.
  • The optional floor closure keeps pests away.
  • Complete opening height is immediately accessible.
  • Short opening and closing cycles (door opens twice as fast).
  • Reduced risk of collisions.
  • Minimized air exchange by reduced opening and closing periods.
  • Low operating costs due to a minimum of wearing parts.

Dortek’s Guide to Fire Door Safety

Fire doors are one of the most critical elements of fire protection. They are used to provide compartmentation – in other words, containing fire and smoke for a period of time to allow people to be safely rescued and evacuated.

Fire doors are often the first line of defence in a fire and their correct specification, maintenance and management can be the difference between life and death for building occupants. Despite this, fire doors remain a significant area of neglect and are often the first thing to be downgraded in a specification or mismanaged throughout their service life.

A review undertaken by FDIS certificated fire door inspectors earlier this year revealed the extent of fire door failures being seen on site:

  • Over 61% of fire doors inspected had problems with fire or smoke seals
  • More than a third had incorrect signage
  • 230 fire doors inspected had gaps bigger than 3mm between door and frame
  • More than 20% had unsuitable hinges
  • Almost 1 in 6 had damage to the door leaf.

(Source: FDIS 32)

The most common identified cause of death from a fire incident is being overcome by gas, smoke or toxic fumes. Suffering from the effects of gas or smoke also accounted for one-fifth of all non-fatal casualties in 2013-14. (Source: This reinforces the importance of properly specified, installed and maintained fire doors with intumescent seals that keep smoke from leaking around the edges of a fire door.

Here’s our checklist to help you specify the correct fire doors and keep them in tip top condition:

  • Always use a reputable and competent supplier – many people claim to make fire doors, but only a handful have a properly tested product which is proven to work in a fire.
  • Ask whether the product has been fire tested and demand to see the documentation that proves it (e.g. fire certificate or label).
  • Make sure test evidence is from a UKAS-accredited test centre
  • Specifying fire doors with intumescent seals is crucial to prevent smoke inhalation in the event of a fire.
  • It’s not just the door itself that matters. The frame and ironmongery is just as important – they all work together. Only buy exact compatible hardware and components from the same reputable supplier, also making sure that the ironmongery also meets the relevant fire test standard as well
  • Correct installation is as important as buying the correct product – fire doors are a carefully engineered fire safety device which must be fitted correctly so make sure you use experienced installers from a reputable company.
  • Ask for the fire door to be installed and then certified using a 3rd-party approved certification programme, such as BM Trada
  • Fire doors should be checked and maintained regularly, to ensure that they still work and perform as intended
  • Make sure you use an experienced door company to manage the servicing and maintenance of your fire doors, using a 3rd-party approved certification programme, such as BM Trada
  • Only ever replace damaged components with like-for-like. A suitably trained individual should be responsible for this maintenance work.

Butzbach Spacelite Stacking Doors

Innovative and space saving

SPACELITE stacking doors are space-saving and low wear. When the doors are opened, the individual translucent door elements line up vertically and compactly one behind the other. A wide range of equipment options make SPACELITE stacking doors a flexible industrial door that is also suitable for large-format doors.

Due to the wall mounting without ceiling suspension, the door is suitable for almost all installation situations – in new buildings and renovations.

For conventional industrial doors of the same size (5.5 x 3.5m), the entire door area is required as additional open space in the ceiling area. With the SPACELITE stacking door, this additional free space is reduced to approx. 17.7% of the comparable area.

In addition to properties such as stability, durability, thermal insulation and resilience, fiberglass also offers light transmission.

The direct drive of the Butzbach door works without wearing parts such as tension or torsion springs. Due to the door sealing and the high light transmission, heating and energy costs can be saved.

The wall mounting of the lifting gates also allows installation on the ceiling of crane runways, extraction systems, lighting, lifting platforms and other installations.

The guide rails are closed on three sides and can thus avoid crushing and injury risks. Thanks to their high corrosion resistance, the doors can also be used in environments with extreme conditions.

Spacelite door benefits:

  • low dead weight
  • heat-insulating, flexible and stable thanks to fiberglass
  • Corrosion resistant
  • High light transmission due to fiberglass door filling (up to 78%)
  • Dimensions up to 15 m wide and 24 m height possible
  • Outdoor installation possible
  • Door leaves with thermally insulated fiberglass web double panels with 40 mm installation thickness
  • Thermal insulation up to Up = 1.4 W/m²K
  • Optional panoramic door leaves made of acrylic or real glass

Product Showcase – Novosprint High Speed Doors

Lateral Thinking for Superior Speed and Safety

Novosprint high speed doors are ideal for all industrial, supermarket and pharmaceutical environments. With its lateral opening technology, its opening speed of up to 5 m/s and its closing speed of up to 2.5 m/s, the NOVOSPRINT door is the most reliable solution for speed and safety in the workplace.

the novosprint principle









Faster Opening

Instead of the traditional vertical opening, the Novosprint door opens horizontally for twice the speed and significantly improved safety. The two halves of the door open sideways in less than a second. This makes the entire height of the door immediately accessible and drastically cuts the risk of collisions or accidents.

Increased Safety

An opening speed of up to 5 m/s and closing speed up to 2.5 m/s enables faster and safer transport of goods. This trouble-free flow of traffic and goods avoids collisions, long interruptions and costly door repairs. The transparent vision panels at eye-level also maintain visibility between one area and the next, even when the door is closed.

More Economical

Low purchase price, low operation costs and low maintenance costs. Short opening and closing cycles reduce draught and heat exchange, thus reducing energy costs and the possibility of illness.

Better Hygiene & Contamination Control

The Novosprint principle of side opening ensures that no dirt spreads from the ground onto workers or any goods being transported. That’s because unlike vertical doors, the door does not come into contact with the floor and pick up dust or dirt which is then left to drip or fall onto passing objects below. The Novosprint hygiene door is an alternative solution which has been developed to meet the requirements of the food and pharmaceutical industries. In compliance with regulations, all tangible parts of the door are made of non porous and corrosion resistant material, such as Stainless Steel and plastics.
