Energy-Saving Performance – High-density closed cell foam insulation is used to meet the demanding ASHRAE 90.1b current standard for minimizing heat loss.  This requirement, allowing a maximum 4 watts per square foot of tank surface energy loss, offers big savings and operating efficiency.

Magnetic Contactors with Immersion Thermostats – 120 volt control circuit with built in transformer.  Elements are thermostatically controlled in 54kW (max) increments.

Low Watt Density Incoloy Elements – Incoloy elements are used by Niles Steel Tank because of their many superior characteristics to copper-sheathed elements in rigorous water heating applications. This tough alloy successfully resists the effects of prolonged high operating temperatures, hard water, acids, corrosion and thermal shock. Their nominally higher initial cost is more than off-set by much longer life expediencies and reduced service and replacement costs. Incoloy elements are designed to “burn in air” to prevent failures caused by water void.

Internal Fusing – All elements and circuits are fused in 48 amp increments, providing complete electrical protection. Cartridge type fuses are rated at 200,000 ampere interrupting capacity.

Glass-Lined Tank – Ultonium glass is applied to the inside surface of the steel tank and fired to 1600 F. (All models are constructed in accordance with the ASME code and approved for 150 psi working pressure).

Magnesium Anode Protection – Provides anodic protection against corrosion of the tank due to electrolysis.

Painted Jacket – The painted steel jacket is coated on both sides and beautifully finished in durable finish. This combines attractive appearance with maximum protection.

Hinged Door with Key Lock – Quality requires full length hinged doors for ease of inspection and maintenance. Keyed door lock provides additional safety and security at no charge.

Digital Temperature Display – Easy to read digital temperature display.

Temperature and Pressure Relief Valve – Factory provided ASME rated relief valve protects against excessive temperature and/ or pressure buildup within the tank.

Terminal Block Connections – Easy and safe wiring connections are made possible by factory installed terminal blocks.
