Worcester supplies cascade systems in TL and TR
configurations:
TL: INLINE INSTALLATION
All boiler assemblies are in a line enabling an easy-to-
monitor installation in a narrow room.
TR: BACK-TO-BACK INSTALLATION
The boiler assemblies are located on both sides of the
frame and are installed back-to-back to create a compact
installation which ideally suits rectangular rooms and
which ensures the best possible access to all boilers.
Depending on the desired output, a choice can be made
between different types.
BOILER ASSEMBLY CONNECTION KIT
The connection kit can be used for the 65-kW, 80-kW and
100-kW version. The connection kit includes a pressure
relief valve, a non-return valve, a pump and isolating
valves.
