  • High impact composite jacket cannot rust or corrode and eliminates damage
High Efficiency
  • 2" thick polyurethane foam insulation reduces standby heat loss providing the industry's highest efficiency heater
Advanced Heating Coil
  • Heating coil can be easily removed for simple maintenance
  • Heavy gauge copper fin tube coil provides maximum heat transfer

Standard Equipment
  • 1/2" thick Hydrastone cement lined steel tank
  • All copper-silicon non-ferrous tank openings
  • Removable heating coil
  • High efficiency copper fin tube heating coil
  • Immersion adjustable electronic thermostat to control the flow of boiler water through the heating coil
  • ASME rated temperature and pressure relief valve set at 150 psi, 210°F, 200,000 BTU max
  • 2" thick polyurethane foam insulation meets or exceeds the requirements of ANSI, ASHRAE, IESNA 90.1-2007
  • High impact colorized composite protective jacket

Optional Equipment
  • 1 1/2" Male NPT inlet and outlet water connections
  • Double wall copper heating coil with a leak detection port
  • Integrally welded seismic attachment points
  • Electric back-up heating element in various wattages in single or three phase voltages
  • Bulb and capillary mechanical thermostat (100-240°F) to accept 24-600 VAC operation voltage; SPST switch 120 Volt (16 Amp), 208 Volt (9 Amp), 240 Volt (8 Amp)

Please note: optional equipment may impact overall dimensions and weight. Please request submittal drawing from factory.
