Check Current PricingAcquire the qualification required for legal and safe operation of filling portable pressure vessels with a capacity over 350 cm³ with fluorinated greenhouse gases.
Filling portable pressure vessels (such as refrigerant cylinders) with liquefied gases requires a qualification certificate issued by the Office of Technical Supervision (UDT). Statutory regulations impose this obligation on all technicians performing recovery and cylinder filling in the HVAC/R industry. Our one-day preparatory course at COCH Kraków provides comprehensive theoretical and practical preparation and coordination of the state examination.
This training is designed for individuals filling portable pressure vessels with a capacity exceeding 350 cm³ and operating temperatures from -20°C to +50°C with liquefied and compressed gases (fluorinated greenhouse gases and controlled substances). Participants learn how to safely operate cylinders and filling stations to avoid risks to life, health, and the environment.
The curriculum combines theoretical lectures with intensive practical workshops at professionally prepared COCH training stations. Participants learn, among other things, how to interpret markings on cylinders, verify their technical condition, connect installations, monitor filling parameters, and perform safe transport and storage procedures.
This training is aimed primarily at installers, mechanics, and service technicians of refrigeration, air conditioning, and heat pump systems who, as part of their daily professional duties, recover refrigerants into cylinders or fill pressure vessels. It is also an essential step for service companies seeking full compliance with UDT regulations and environmental protection laws.
An intensive 1-day program combining theoretical lectures with practical workshops led by experienced COCH engineers.
Standards, legal requirements, and executive acts concerning the filling, storage, and supervision of portable pressure cylinders.
Characteristics of fluorinated greenhouse gases, saturation pressure, density, filling ratios, and hazards associated with cylinder overfilling.
Design of double-valve and single-valve cylinders, design of safety valves, shut-off valves, seals, and siphons.
Interpretation of stamps and engravings on the cylinder, cylinder color-coding according to gas type, nameplates.
Personal protective equipment, procedures in case of leakage or fire, first aid for frostbite.
Identifying mechanical damage, corrosion, verifying the validity of periodic inspection tests (UDT certification), and valve operations.
Connecting cylinders to recovery/filling stations, operating electronic scales, monitoring pressure and temperature.
Practical calculations of refrigerant weight based on water capacity of the cylinder and the filling factor for the given gas.
Selection and correct placement of warning labels containing information on gas type and mass in accordance with the F-gas regulation.
We are a leading training and certification center in Poland with decades of experience in the HVAC/R industry. Choose quality and expertise.
Thanks to our excellently prepared curriculum and highly qualified instructors, our trainees achieve exceptional results in UDT examinations.
Practical exercises take place on real workshop stations and filling setups using modern equipment and gauges.
We handle all the paperwork - from verifying exam applications to registering and coordinating dates with the UDT commission.
We provide participants with a hot, two-course restaurant lunch and a continuous coffee buffet with snacks throughout the training day.
Trainings take place at our Kraków facility, with access to free, secure parking for all participants.
Quick and convenient prepayment transfer to the COCH account at least 3 days before the training.
Payments for the training should be made to the following COCH bank account in Kraków:
To sit the exam, it is mandatory to submit a complete set of application forms and a power of attorney beforehand.

A two-stage assessment of qualifications before inspectors of the Office of Technical Supervision.
The state exam takes place immediately after the training at the COCH headquarters in Kraków. It consists of two independent parts, both of which must be passed:
UDT Pressure Vessel Filler Permit - legal base
A qualification certificate for the filling of portable pressure equipment is issued by the Office of Technical Supervision (UDT) in Poland. It confirms competence under technical safety standards and authorizes safe handling and filling of portable gas cylinders. Highly essential in the HVAC sector for any refrigerant recovery operations.
A discussion with the examination commission. The candidate draws a question set: 2 general questions (minimum 1 pass required) and 3 specialized questions on the gas group (minimum 2 passes required).
Performing portable cylinder filling. The inspector assesses: cylinder condition evaluation, connection correctness, filling weight monitoring, compliance with H&S rules, and proper tagging of the filled cylinder.
Upon passing the exam, the Office of Technical Supervision issues an official, plastic qualification certificate authorizing the filling of portable pressure vessels. Credentials are valid indefinitely.
