A.O. Smith ITS - Dual Coil Indirect Water Heaters Series
A.O. Smith ITS - Dual Coil Indirect Water Heaters Series
The A.O. Smith ITS Series represents a comprehensive range of dual coil indirect water heaters designed to meet diverse hot water needs across residential, commercial, and light industrial applications. Offering capacities from 300 to 1007 liters, the ITS Series combines efficiency, durability, and versatility in a well-engineered package.
Series Overview
The ITS Series consists of six models: ITS 300, ITS 400, ITS 500, ITS 600, ITS 750, and ITS 1000. Each model is equipped with two single-wall spiral heat exchangers, providing flexibility in installation and operation. The bottom coil offers higher output, ranging from 46 kW in the ITS 300 to 87 kW in the ITS 1000, while the top coil provides additional heating capacity, ranging from 26 kW to 58 kW across the series.
Key Features
- PermaGlas Ultra Coat Enamel: All models feature this high-quality lining, ensuring excellent corrosion resistance and prolonging the life of the tank.
- Dual Coil Design: The presence of two heat exchangers allows for integration with multiple heat sources, such as boilers, heat pumps, or solar thermal systems.
- Insulated Construction: An insulated ring base facilitates easy installation, while the insulated clean-out door enables comprehensive maintenance. The standard removable insulation jacket enhances energy efficiency.
- Corrosion Protection: Each model comes with a replaceable anode, providing additional protection against corrosion and extending the unit's lifespan.
- Flexible Installation: Options such as a flexible anode are available for installation in confined spaces.
- Safety and Monitoring: Optional temperature and pressure valves, as well as an analogue temperature gauge, ensure safe operation and easy monitoring.
Performance and Efficiency
The ITS Series offers impressive draw-off capacities, with the largest model, ITS 1000, capable of delivering up to 2557 liters in 30 minutes at a 44°C temperature rise. Energy efficiency ratings are available for models up to ITS 500, all achieving a respectable Class C rating. Standby losses range from 92W for the smallest model to 146W for the largest, demonstrating the effectiveness of the insulation across the series.
