Heavy Duty Stainless Steel construction
High flow rates
Three electric elements for quick recovery
Suitable applications include:
- Hotels and motels
- Apartment blocks
- Factories/process
- Shower blocks
- Wash down facilities
- Commercial laundries
- Any hot water requirement where gas is not available
We recommend the installation of a Quick Recovery electric tank system when access to gas is not a realistic proposition. Ideally suited for a commercial building or industrial application that has a predictable volume of hot water consumption, in high flow rates, that require regular peaks of water.
Available with electric element sizes in either 3.6kW, 4.8kW or 6.0kW there is a model with enough power to satisfy any demanding application. Quick Recovery Electric storage tanks (or QRE tanks) can be used on flow and return systems that distribute the water around a building.
Note: This product is not available across all regions of Australia. Please contact your local commercial hot water specialist with your application requirements and they will be happy to help.
