2 The Heaters uniquely accommodate applications with low line pressure, while still accommodating ANSI standard flow rates. The durable components withstand higher pressures which result in a longer service life, while ensuring the delivery of precise output temperature. Keltech s durable components withstand power abnormalities found in industrial environments and ensure tepid water standards are never exceeded (100F), with its three-tier anti-scald protection and hot water tankless systems do not require the installation of an emergency thermostatic mixing valve. The door cut-off switch disables the unit and minimizes live components should unit internals be accessed without terminating electrical service. The NEMA 4 Enclosure (General Area) is durable and waterproof. NEMA 4X Enclosure offers the same features as a NEMA 4 enclosure, with corrosion Delivery TemperatureFactory set at 80 F, not field (kW)VoltageAmperage364804336600355448065 5460052634807663600617248087726006910848 0132108600104126480152126600121144480174 144600139 Electrical Specifications for the Heater 2013 Keltech Incorporated729 South Grove Street, Delton, Michigan 49046 Phone: 800-999-4320 Fax: 2 of 4 This information is subject to change without notice.
