Hot Water Generators Home / Hot Water Generators Hot Water Generators Niles Steel Tank Hot Water Generators are equipped with 2 or 4 pass, single or double wall construction, U-bend heat exchangers. It can be operated by passing either steam or hot water through the coil to heat the tank contents. Large heating capacity in small spaces makes this heater particularly suitable for boiler rooms with low head room. Hot Water Generators come in vertical and horizontal configurations, bare, topcoated or jacketed and insulated. Select from our standard design or customize as needed. All tank fittings can be NPT, flanged or grooved end. Most generators are porcelain enamel (glass) or epoxy lined for potable water applications up to 180°F & 160 PSI max. For higher temperatures or special applications NST offers 316L stainless steel tank construction. These systems are designed primarily for natural convection in the tank. Heat exchangers are built with your choice of copper, stainless or copper nickel tubes. All tubesheets are 304 stainless steel unless requested otherwise.
