Entrance to museum is by middle door.
Firefighting area
It’s close to entrance of Technical Museum Nikola Tesla. In this area, are shown vehicles and equipment used by Fire Brigade Zagreb and Volunteer Fire Company. A manual fire pump with double-cylinder, used around 1900.
An educational panel explains conditions to have fire: Oxygen, fuel material and material’s ignition temperature. Each switch on left represents one of these conditions. When 3 conditions are met, central light representing fire is on.
This flag marked the control point of fire fighting operation. At night, were implemented lamps.
A water supply wagon moved by horse. Had capacity for 450 liters.
Rucksack for firefighting V-25, could carry up to 25 liters of water.
Another double cylinder manual pump, also used around 1900.
An adjustable nozzle, were installed on top of a ladder to erase fire in high buildings.
This is a Magirus K 20, used in 1924. Ladder can be extended to 30 meters. The engine had 4 cylinders and was cooled by water. In addition to 50 kW at 1100 rpm.
A centrifugal water pump from Fiat, with four cylinder petrol engine and cooled by water.
Protection equipment for firefighters. From late 19th century and 1920s.
A wagon pushed by horses which transported a manual pump.

In this section there are many types of fire extinguishers and pumps.
These vehicles transported firefighters and their equipment. A Chevrolet from 1931 and an Opel Blitz from 1939, respectively.
Energy conversion
This section has many old steam engines, combustion ones, hydro turbines and some electric machines. Not all are present in this post. This is a steam engine with a single horizontal cylinder.
This is a centrifugal suction pump, manufactured by AEG in 1911.
Francis hydro turbines of 8 kW and 110 kW, respectively.
19th century water mill.
A Pelton turbine.
A boiler, produced steam to move engines’ pistons.
Steam engine with a single vertical cylinder. Both are double acting, by that, high pressure steam acts in both sides of piston to generate motion.
Steam machine with a single cylinder double acting. Manufactured by Masch, Tanner, Laetsch & co in 1908 in Vienna, Austria. Touchscreen in red shows the machine in operation.
The steam engine is linked through a belt to a direct current generator model GM-265, whose nominal power is 30.5 kW. The latter was made by Siemens-Halske in past century.
Two steam marine engines, to propulsion of ships and boats. Both have two double acting cylinders.
