Dependable, Tank Type Water Heaters for
Commercial and Industrial Applications

Charger Low NOX

The Low NOx Charger gas fired, tank type water heaters are designed to

provide ease of installation, low stand-by loss and years of trouble free service.

Chargers are ideally suited for apartments, schools, food service and many other

commercial and industrial applications with requirements for hot water. They are

built to ensure easy installation and maintenance.

Induced Draft Operation

The Low NOx Chargers features a low NOx burner that is specially designed to

deliver less than 30 ppm of NOx emissions. In addition to the low NOx burner,

the Charger uses a specially designed blower to precisely and efficiently control

the flue products in the exhaust piping.

Outstanding Features / Quality Design

The Low NOx Charger features a multi-flue design for increased efficiency and

fast heat transfer. The tank is glass lined for prolonged life and protection from

rust and corrosion. The tank is certified for 150 psi working pressure and is

available in standard construction or ASME construction over 200,000 Btu/hr

input. Multiple anode rods are installed for additional protection from corrosion.

Water Heaters

Ease of Installation

Low NOx Charger installations are fast and easy. The water heaters are fully

assembled and ready to drop into the any applications. The Charger has a small

footprint and is often shorter than competitor models. The Charger is designed

with three sets of water circulation tappings. Water connections on the top, the

front and the back provide ultimate flexibility, especially on retrofit applications.

Even More to Offer

All Low NOx Chargers feature spark ignition which is much more efficient than

traditional standing pilots. Hand hole cleanouts and slide out burner trays offer

superior serviceability. And all models are combustible floor approved.
