LDX 2101 Stainless Steel Construction
The cylinder body is manufactured from LDX 2101 stainless steel, providing the main storage vessel construction for the Joule Cyclone Platinum 125L. The cylinder is finished with a coated mild steel outer casing for a clean and durable external finish.
The combination of the stainless steel cylinder body and coated outer casing provides a robust construction for domestic and light-commercial hot water storage applications.
20kW 316L Stainless Steel Heat Exchanger
The indirect heating system uses a single 316L stainless steel heat exchanger coil designed to transfer heat into the stored domestic hot water.
- Coil rating: 20 kW
- Coil surface area: 0.58 m²
- Maximum primary pressure: 3.5 bar
- Coil resistance: 0.05 bar
- Number of heat exchangers: 1
The 20kW coil provides the primary indirect heating capability, making this cylinder suitable for systems where stored domestic hot water is heated through an indirect primary circuit.
3kW Immersion Heater Backup
The cylinder includes one 3kW immersion heater rated at 230V, providing an additional electric heating option alongside the indirect coil. This gives installers and users greater flexibility when heating the stored hot water.
Single immersion configuration.
Specified immersion heater rating.
Provides heating flexibility through coil and immersion.
Dense PU Foam Insulation
The Joule Cyclone Platinum 125L is specified with dense PU foam thermal insulation to help reduce standby heat loss. The supplied specification gives a heat loss value of 1.25 kWh/24h.
The foam thickness field is supplied as 0 in the product specification and has been retained as provided without interpretation.
