Thinking about heating when it’s hot outside? It’s smarter than you think. Summer is a great time to plan ahead for winter by upgrading or installing high-performance Unit Heaters in your building. At SPC, our CiRRUS Unit Heaters are engineered to deliver powerful and efficient warm air heating, ideal for warehouses, factories, garages, and other commercial or industrial spaces.
What Makes SPC CiRRUS Unit Heaters Different?
Designed for Demanding Spaces
CiRRUS Unit Heaters are purpose-built for large-scale environments such as distribution centres, workshops, and plant rooms. Horizontal and vertical mounting options provide flexibility to suit your layout.
High Performance, Low Fuss
Available in water-heated and electric versions, units deliver up to 50.9kW of heat (with 3-row coils) and are suitable for boiler and heat pump systems, including low-temperature operation.
Smart Airflow Control
EC fans with 0-10V control allow full adjustment of airflow and noise levels. Adjustable louvres provide precise air distribution, maximising comfort across your space.
Built to Last
Heavy-duty steel casing, corrosion-resistant powder coating, and copper/aluminium coil construction ensure long-term durability with minimal maintenance.
Flexible Mounting Options
Wall brackets, ceiling suspension rods, or unistrut systems make installation simple and adaptable.
