THERM 90 KD.A
1.1 Use
The hinging condensing boiler THERM 90 KD.A is modern gal appliance suitable for heating of objects with the thermal loss
up to 90 kW in the stand-alone mode, and even for the larger object with higher thermal loss in the cascade connection.
Required power of the boiler plant can be gained by composition of boilers to cascade controlled by own regulation, incl.
equithermic. Thus by simple assembly, it is possible to obtain the heat source with high efficiency, smart operation and
high reliability. The boiler units themselves are designed as the consumers with use of the water steam condensation in the
combustion process and excels with high efficiency with minimum emissions to the atmosphere. It means the economic
operation without any adverse effects to the environment. Power of the boiler is smoothly adjustable within 27 – 100 % and
adopts itself automatically to the needs of the object. The top components from world leading manufacturers provides high
technological standard of the boiler.
!
Correct operation of the boiler requires to maintain the minimum pressure of the water in the heating system
of 0.8 bar (measured in cold state). With regard to their power and use variability, the THERM 90 KD.A boilers
are not fitted with expansion vessel. If the boiler is connected to the system with open expansion vessel, it must
be in minimum height of 8 m above the boiler.
