Dual-Coil Heating Technology
The Joule Cyclone 200L cylinder features two 316L stainless steel heat exchangers, providing flexibility for systems using multiple primary heat sources. Coil 1 has a 21kW rating and 0.67m² surface area, while Coil 2 is rated at 35kW with a stated 37m² surface area.
The dual-coil configuration is suited to installations where separate heat sources may be required, including systems combining a boiler with solar or heat pump technology. The cylinder is designed for an operating temperature of 60°C.
Stainless Steel Construction & Thermal Insulation
LDX 2101 Stainless Steel
The cylinder is constructed from LDX 2101 stainless steel, providing the specified corrosion-resistant construction for long-term hot water storage.
Dense PU Foam
Dense polyurethane foam insulation is specified to help reduce standby heat loss, with a stated heat loss of 1.94 kWh/24h.
Coated Mild Steel Casing
A coated mild steel outer casing provides the specified durable and serviceable external finish.
Electric Backup
One immersion heater is specified at 3kW @ 230V for electric backup boosting.
Pressure & Safety Performance
The Joule Cyclone 200L is designed for installations with higher mains pressure, with a stated maximum mains water pressure of 10 bar and an operating pressure of 7 bar. Coil pressure capabilities vary by heat exchanger, with Coil 1 specified up to 3.5 bar primary pressure and Coil 2 specified up to 40 bar.
The cylinder has an operating temperature of 60°C and a safety valve temperature of 90°C. It has been tested to BS EN 12897:2016.
Installation & Handling
With an empty weight of 41kg and a stated full weight of 241kg, handling and siting requirements should be considered during installation. The cylinder's vertical configuration makes it suitable for installations where plant room depth is limited, according to the supplied product information.
