CASCADE

Cascade boiler systems

The Upsilon cascade system is quick and easy to install thanks to the Plug & Play – principle. The diversity in configuration options enables the installation to be placed almost anywhere, whether it is an existing location or a new built. Features A.O. Smith delivers the entire package; it just needs to be put together. The quick fit hydraulic pipe work header fixes the boiler support frames with all the interconnecting pipework. Dependent on the installation a DN 65 or DN 100 low velocity header will be supplied. Insulation sets are available for the flow and return pipes. The Upsilon cascade system can be wall or frame mounted. In the frame mounted option it is possible to place the boilers in line or back to back. A.O. Smith will provide you with the required mounting set together with all the other parts used in the cascade installation. The hydraulic systems are available in modules for 2 or 3 boilers fitted with double connections for back-to-back assemblies. The connection sets between the boiler and pipe work headers are fitted with gas insulation valves and service valves. The Upsilon cascade system is designed to fit into multiple layout options. This allows the designer to maximize the use of the available plant room space for other installations.
