We take a medical facility from the first sketch to the point where the equipment runs lawfully and someone maintains it.
Equipping a medical room that houses an ionising radiation source is a procedure, not a purchase. Between the decision to buy and the first patient sit the design, the approvals, the construction, the installation, the measurements and the acceptance committee. A missed step in that chain usually surfaces at the worst moment — when the facility cannot be commissioned.
ERGIN Ltd. covers the whole chain. That is not merely convenient: it keeps the risk in one place. When design, supply and installation run through different contractors, responsibility for the gaps between them tends to land on the client.
01
Design of medical facilities
We prepare the two parts of the investment design that make a room fit for medical equipment: the technology part and the radiation protection part. They go together — where the unit stands determines the shielding, and the shielding in turn constrains where it can stand.
The technology part sets the functional layout of the rooms with the medical equipment drawn in, the flows of patients, staff and materials, and the equipment specification. From it follow the requirements for the architectural, electrical, plumbing and HVAC parts: where power is needed and at what rating, where water and drainage go, what ventilation is required, what floor loading, how wide the doors must be and where the routes run.
The radiation protection part calculates the shielding required for every barrier — walls, floor, ceiling, door and observation window — starting from the type and parameters of the equipment, the expected workload, the distances and the use of adjacent rooms.

Flows of patients, staff, clean and waste materials
Specification of the medical equipment and fittings
Requirements towards the other design parts — electrical, plumbing, HVAC, structural
Explanatory note for the approval procedures
Radiation protection part
Shielding calculation for walls, floor, ceiling, doors and observation windows
Specific lead equivalence requirements for each element
Definition of controlled and supervised areas
Documentation for approval by the competent authority
Facilities we design
X-ray rooms — radiographic and fluoroscopic units
Computed tomography (CT)
Mammography
C-arm and angiography suites
Dental rooms — intraoral, panoramic and CBCT
CR and DR systems
Nuclear medicine and radiotherapy rooms
The design is assessed by the competent authority, which also issues the design permit for the site, approves the operating documents and takes part in the acceptance committee with its health opinion.
02
Service, installation and commissioning
We install, remove, commission and decommission radiological and specialised medical equipment. Planned maintenance extends equipment life and reduces unplanned downtime — for a department with a single CT, every day of downtime is a day of deferred patients.
Installation and commissioning of new equipment
Removal and decommissioning of old equipment
Scheduled preventive maintenance and corrective service
Support for dosimetric measurements and barrier verification
Preparing the documentation for commissioning the facility
We work nationwide. For equipment outside our own partnerships we assist with coordination towards the relevant manufacturer.
03
Consulting and technical support
The most expensive mistakes in medical technology are made before the order is placed. A unit that does not fit the room, a configuration missing the required software module, or a choice whose consumables turn out to be unavailable on the Bulgarian market — each of these is settled at the table, not after delivery.
Assessment of the technical environment and of what the room allows
Comparing configurations against the real clinical workload
Drafting technical specifications
Planning timelines and the sequence of works
Training the team to operate the equipment
04
Supply of medical devices
ERGIN Ltd. is a registered wholesale distributor of medical devices. We supply equipment, devices, consumables and radiation protection — both for equipment we delivered and for systems already in service.
Immobilisation systems and thermoplastics for radiotherapy
Medical scales and measuring systems
Dental radiology and digital imaging
Bone densitometers
Patient positioning markers
Radiation protection equipment and lead glass
How a project runs
The sequence below is typical for a new room with an ionising radiation source. When equipment is replaced in an existing room, some steps fall away.
Enquiry and site visit
We establish the intended use of the room, the type of equipment and the expected workload. Where needed, we come on site.
Technical proposal and quotation
We propose a configuration matched to the room and the clinical task, with timelines and scope of works.
Design
We prepare the technology and radiation protection parts with the accompanying documentation, and obtain approval from the competent authority.
Construction and shielding
Barriers, doors and windows are built to the design; the rooms are prepared to the technological layout.
Delivery and installation
The equipment is delivered, installed and commissioned.
Measurement and acceptance
Dosimetric measurements are performed, the facility is checked for readiness and commissioned.
Training and maintenance
The team is trained on the equipment; planned maintenance is agreed.
Questions and answers
Frequently asked questions
Which parts of the investment design do you prepare?
The technology part and the radiation protection part. The technology part sets the room layout with the equipment drawn in, the flows and the equipment specification, and states the requirements for the electrical, plumbing, HVAC and structural parts. The radiation protection part calculates the shielding of the barriers. The remaining parts are prepared by the respective designers, working from the brief that comes out of our technology part.
What does the radiation protection part of the design include?
A calculation of the shielding required for every barrier — walls, floor, ceiling, door and observation window — derived from the type and parameters of the equipment, the expected workload, the distances and the use of adjacent rooms. The result is a specific lead equivalence requirement for each element, which then goes into construction.
Why must the technology part come before the others?
Because it states what goes into the room and where. The power rating, the water points, the ventilation, the floor loading and the door widths all follow from the specific unit and its position. If the electrical or plumbing part is designed first, it usually has to be reworked.
Is approval needed before construction starts?
Yes. Sites with ionising radiation sources require a design permit, and the investment design is assessed by the competent authority. Starting construction beforehand risks barriers that turn out to be inadequate and have to be rebuilt.
What lead equivalence does my room need?
There is no universal answer — the value comes out of the calculation for that specific room. The same unit in two different rooms may require different shielding if the adjacent rooms serve different purposes or the workload differs.
How long does it take to commission a room?
Mainly it depends on the approval procedures and the construction, not on equipment delivery. On enquiry we give a realistic timeline for the specific case — more useful for planning than general figures.
Do you remove old equipment?
Yes. Decommissioning and removal of radiological equipment are part of our services and often run together with the installation of the new system.
Do you supply consumables for equipment you did not sell?
Yes. As a registered wholesale distributor of medical devices we supply consumables, accessories and radiation protection regardless of who delivered the main equipment.
Do you work across the country?
Yes. We have delivered projects at healthcare providers in various cities — Plovdiv, Sofia, Blagoevgrad and others.
How do I request a quotation?
Describe the room, the type of equipment and what you are planning — with as much information as you have. If something is missing we will ask. We reply with a technical proposal or with clarifying questions.
