RENDAMAX R3400, R3600

Small dimensions and weight of boilers at high efficiency values is achieved through the use of two flow heat exchangers. The first heat exchanger is made of smooth tubes made of stainless steel. The second heat exchanger consists of ribbed stainless steel pipes with laser welding of the base of the fin. The special design the supercharged gas torch with a tilted distributed torch built into the boiler's design ensures stable combustion conditions in the entire power control range from 20 to 100% while maintaining the technical characteristics:
- Efficiency - not less than 95%
- extremely low emission of carbon monoxide (CO) from 2 to 11 ppm and nitrogen oxides (NOx) from 10 to 30 ppm (in terms of dry undiluted combustion products)
- Low equivalent noise level (up to 40 dBA) at rated power.
The flow rate is controlled by a 3-mode circulation pump. The running of flow-through boilers with a high velocity of the coolant motion ensures an operation without scale of heating surfaces on water with moderate hardness (up to 4.5 mmol/l). The rational design of atmospheric flow-through hot water boilers of the R 3400 series from Rendamax allows to quickly perform the assembly and disassembly of the boiler, which ensures the simplicity and convenience of repair and maintenance. Atmospheric flow-through hot water boilers of R 3400 series by "Rendamax" are equipped with digital blocks of automatic control and safety automatics, as well as fault indicators.
