Heavy shielding doors

Heavy shielding doors are a highly specialized product that must meet a number of requirements from the radiation absorption point of view, aesthetics, functionality and safety in everyday use. We design, manufacture, supply, install and service (maintain) heavy protective doors for bunkers of accelerators, cyclotrons, brachytherapy and other rooms with devices that are a source of high energy radiation. Our product is a guarantee of radiation shielding effectiveness, safety of use and modern design. Doors are covered by a standard warranty from 2 to 5 years.

All-purpose solutions

We design, manufacture, supply, install and maintain heavy protective doors for rooms with low and high energy radiation sources. Our solutions have been used in oncological centres, scientific-research centres as well as in companies specializing in non-destructive testing (NDT). This proves that the solution we use is versatile and meets the requirements for these special rooms. Our doors are characterized by solidity and durability, and are extremely important features in such important branches of the economy as medicine or development-research centres. As a few, we made the door to the machine room of the cyclotron bunker with EI30.

Safety above all

Safety above all

When designing our doors, we put safety first in their use. On the one hand, it is to ensure radiation shielding effectiveness so as not to expose unauthorized persons to harmful radiation. On the other hand, we try to ensure maximum safety for people working in the bunker, that is, medical physicists, scientists, engineers and other qualified people to work in these specialized places. Based on many years of experience, we are able to provide it all. We guarantee radiation tightness, and the occupants’ safety is ensured by systems of presence in the door light (presence detectors, security curtain) and overload systems (protection against jamming).

Proven construction

Proven construction

The heavy shielding door we offer is a steel construction, high quality and very versatile. It does not matter what type of shielding materials you should use and what is the thickness of each coating. We have solutions for all protective materials available on the market – liquid and solids. We have knowledge and experience in heavy door installations up to 11 tons. We have successfully completed over 20 heavy shielding door installations that fulfil our function and individual requirements of our clients.

Availability and flexibility

Availability and flexibility

We value the time of our clients, so we understand the situation where it is very little and we need quick decisions and immediate start of activities related to the supply of shielding products. We are enabled by efficient production, several assembly teams and extensive experience in this specialized industry. Thanks to this, we are able to provide heavy shielding doors in the manual version in 2-3 weeks, and the automatic version in 4-5 weeks. We have our own fleet adapted to transport this type of non-standard products and a set of logistic devices such as mobile cranes, winches or unloading ramps to meet this task.

0 2 Heavy door types

DNR doors have a welded construction made of high quality steel. The shielding materials are inside the door, solidly fixed and tightly closed with the outer shell. The weight of the door is transferred each time by two bearing hinges – the lower (retaining) one by the upper (positioning).

DOORS DNS have a welded construction made of high quality steel. The shielding materials are inside the door, solidly fixed and tightly closed with the outer shell. The weight of the door rests on ball bearings placed in a precise guide rail (guide). The positioning element is a wall or floor roller.

Hinged and sliding doors

Hinged and sliding doors

Just like traditional doors, heavy shielding doors can be divided into hinged (DNR) and sliding doors (DNP). The type of door is always specified by the ordering party.

Manual doors with automatic

Manual doors with automatic

Our heavy shielding doors can be made in manual or automatic version – with an electromechanical power operator.

We divide the door by weight. We can prepare door with the weight up to 500-600kg in the manual version. A heavier door requires the use of too much force to give them opening speed, but above all to stop them when they acquire momentum. Manual operation of doors with a weight of over 500kg may be dangerous for the user and serious injury has occurred.

0 3 Power operators

Advanced security systems, durable and solid construction are the features that distinguish our product. Power operators can be installed inside or outside the bunkers. As standard, automation has the ability to control its functions from the panel with dedicated, backlit buttons to: open total, half open, close and stop the door. The control panel also has a safety button that cuts the power supply. The standard peripherals supplied with the door are: two door switches, two control panels and two handles for manual work during automation failures.

Regardless of the type of door – sliding or hinged, our power operators are chosen for the weight of the leaf:

  • up to 2000kg,
  • up to 5000kg,
  • up to 11000kg.

Automation as standard are equipped with a programmable PLC controller with the possibility of fast personalization of the system operation. In an easy way, at the customer’s request, we can program (adjust):

  • The speed of opening and closing the door,
  • The angle of opening the door,
  • Half-open angle of the door (or any other),
  • The so-called soft close and soft open, e.g. smoothness and “gentleness” of moving,
  • The strength of the door clamp to the frame.

The door can be equipped with optional peripherals such as:

  • Mechanical locking system of closed doors,
  • Access control adapted to the procedures prevailing in the given institution,
  • Additional control panels located in accordance with the client’s request,
  • Light signal for the door position – closed / open.

Door finishing

In addition to technical parameters, customers more and more often pay attention to the aesthetics of the door. Even for specialist heavy bunker doors.

The standard finish for our heavy doors is that of painted aluminum. Standard colors are RAL 7047 but the final decision depends on the ordering party and includes any colour from the RAL palette. Optionally, the door can be covered with brushed stainless steel. Regardless of the chosen type of finishing, the corners are aesthetically rounded and the whole looks very modern. The door leaf is equipped with two handles. One from the inside of the bunker, the other from the outside. Both are made of stainless steel.
At the customer’s request, any door leaf personalization is available.
