HeaterHeaterHigh-efficiency burner/blower for low carbon monoxide and nitrous oxide emissions. Able to meet stringent emission standards.

Water pressure limit switch and high temperature switch shut down the unit for safety if water pressure fails or is accidentally shut off.

Electrical programmable logic controller (PLC) for building automation system compatibility. NEMA 4 (watertight) enclosure, modular components for easy service or replacement. Status lights for easy troubleshooting.

Stainless steel construction with a five-year warranty on the structure and its internals. Indexability of the top portion to the bottom

allows for flexibility in rotating for easiest utility hookups. Allows for ease of internal inspection.

Exhaust temperatures between 40°C and 120°C allow for inexpensive CPVC or single-walled stainless for ducting materials.

Modular fuel train using slide out components for ease of maintenance or replacement. CSA, UL and FM approved.

Small footprint because the burner is installed on top of the unit and not on the side. No side clearance required.

Level controls automatically control the transfer pump (included) which delivers heated water to application.

Stainless Steel Pall Rings

• Double “Pass” Unit• Transfers heat through the heat tube and then as it

rises to exhaust through Pall rings

• Efficient Heat Transfer• Large temperature differential between the flame

and the water• Pall rings produce a large surface for heat transfer• Condenses the water formed during combustion.

Approximately 10% of the available heat is normally lost up the stack

• Scale Resistant• Virtually “immune” to scale build-up. Heat is on the

same side of the metal surface as the water

• It is not the best for “people washing”

• A good initial evaluator is: Customer must use 25,000 Gallons of HW per day to see value

• When water above 120°F is re-circulated back through the water heater the efficiency is lost because water normally condensed during combustion is now lost out the stack

• In the correct applications there is………
