Closed expansion vessels
Compensates for water volume changes due to temperature fluctuations, ensuring stable pressure and protecting equipment.
TIPO Kotlogradnja manufactures high-quality pressure vessels for safe operation with pressurized fluids in industrial and energy systems.
All vessels are produced according to applicable standards and customer requirements, ensuring durability, safety and long service life.

We manufacture pressure vessels in our own workshop, from seamless steel tubes and certified plates, in accordance with the PED 2014/68/EU directive and pressure equipment standards. Every vessel is delivered with a strength calculation, pressure test and certificate, with radiographic or ultrasonic testing of welds where the vessel class requires it.
The range covers steam and water headers and collectors for district heating and industrial plants, including large diameters for power plants, closed expansion vessels for hot and warm water systems, hydrophore vessels for stable pressure in water networks, shell-and-tube heat exchangers, condensate expanders and economizers with finned and smooth tubes.
Vessels are engineered to order, with inspection openings, connections for pressure gauges and thermometers, drainage systems and anti-corrosion protection, both for new boiler plants and as replacements for worn vessels in existing systems.

Compensates for water volume changes due to temperature fluctuations, ensuring stable pressure and protecting equipment.

Optimizes the distribution and collection of steam and water, ensuring balanced operation and simplified piping layouts.

Maintains constant pressure in water supply systems, ensuring stable distribution and protecting pumps from overload.

Highly efficient heat transfer between two media in a compact design, for diverse industrial applications.

Recovers waste heat from flue gases to significantly boost boiler efficiency and lower fuel costs.

Recovers valuable energy during pressure reduction, minimizing thermal losses and enhancing system efficiency.
