2 NX THE ULTIMATE IN DEPENDABILITY AND PERFORMANCE The Hubbell NX is a heavy-duty, fully condensing commercial gas water heater coupled with a long lasting cement lined Hubbell storage tank. The Hubbell design achieves a thermal efficiency rating of 96% and is available with inputs ranging from MBH. The NX series integrates the best of both worlds by combining a high efficiency, high recovery gas water heater with a properly sized cement lined storage tank, reducing energy consumption, short-cycling, and stand-by heat loss. FEATURES BTU input from 200 to 800 MBH 316L stainless steel heat exchanger Up to 8:1 turndown Numerous venting options BMS integration via open communication protocol Minimal storage required Feature rich interface using touch panel controller Scale reducing design ASME stamped BENEFITS BENEFITS Low pressure drop Cascadable up to 8 NX water heaters for up to 6.4 million BTUs Typical NX Configuration High efficiency gas fired water heater coupled with a Hydrastone cement lined storage tank. Example Shown: Model NX 800,000 BTU shown plumbed to a Hubbell 160 gallon Hydrastone lined storage tank. 96 % Thermal Efficiency Sustains initial thermal efficiency over life span of heater Innovative floor or tank mount configuration provides exceptional access to all components Increased serviceability Offers the flexibility of multiple BTU inputs and unlimited storage configurations 1 Hubbell Heater Company P: F:

3 How It Works The Hubbell NX gas water heating system offers a state-of-the-art modulating combustion system with innovative floor and wall-mount configurations, providing exceptional access to all components. The NX can be integrated with Hubbell s long lasting cement lined storage tank, giving you a product built for demanding commercial/industrial applications. The NX advanced digital control system and spark ignition with dual electrodes and high-output transformer, provides unparalleled ignitions. Hubbell s 316L stainless steel, ASME certified heat exchanger with fully modulating burner is integrated into a high-quality cabinet with corrosion resistant clear coat finish, making the Hubbell NX best in class. Hot Water Outlet Hydrastone Lined Tank A seamless 1/2" thick cement lining is impervious to adverse water conditions and is proven to be the most effective method of preventing tank failure due to corrosion. Polyurethane Foam Insulation Exceeds the requirements of ANSI/ASHRAE standards for energy efficiency and heat loss.
