• Tank
The Hubbell tank is all welded heavy steel construction designed for 100 psi
working pressure and tested to 300 psi. Each tank is centrifugally lined
with 1/2" thick seamless high density Hydrastone cement with guaranteed
100% coverage of all steel surfaces. All tank openings are non-ferrous solid
copper-silicon and are resistant to the corrosive effects of hot water.
• Mounting
System
Factory constructed heavy-duty leg supports are integrally welded
to the tank to provide for securing the tank to the deck. Side-sway
bulkhead attachment points
are provided for added mounting integrity. This mounting support system provides
a stable water heater installation with improved safety.
• Plumbing
3/4" combination cold water inlet and drain, with non-corrosive strata flow
diffuser which prevents incoming cold water from mixing too rapidly with the
hot water in the tank and assures delivery of more hot water — not lukewarm
water.
A 3/4" hot
water outlet with a uniquely designed built-in heat trap prevents
heated water from radiating through the piping
during standby periods.

• Electrical
Copper sheathed immersion heating elements with low watt density for prolonged
life — up to 6 KW in 120, 208, 240, 277, 480 volt single phase (See
chart for details). An adjustable surface thermostat operates in 110-170
oF range.
Integral hi-limit with manual reset button for over-temperature protection is
factory set at 190 F.
Upper and lower element configurations are factory wired for non-simultaneous
operation.
• Insulation
Highly efficient 2" thick polyurethane foam insulation exceeds the latest
ASHRAE standards for energy efficiency and heat loss.
• Jacket
The exterior protective jacket is constructed from high impact
composite material which cannot rust or corrode and does
not require painting. |
