Now 30% smaller than the previous cascade configuration, it is perfect for plant rooms with lower footprints or with a small headroom, as the boiler height can be adjusted on the frame. Suitable for row, block or even corner installations, the compact cascade can be wall mounted or simply fitted with a free-standing frame for 2,3,4,5 or 6 boiler units at a time. This can deliver a maximum output of 594 kW with a 6 boiler cascade
Addition Accessories required
Adaptor flanges DN 100 to R 2
Can be used for total heating outputs of up to 200 kW in conjunction
with a cascade module adaptor
