Armstrong International offers a range of gas-fired hot water heaters. Its Flo-Direct is designed for applications such as laundries where large amounts of water are used every day.
Flo-Direct has a top mounted gas burner that fires downward through a centrally located flame tube. The resulting heat from the flame heats the falling water, which comes in contact with the bed of packing rings where heat transfer occurs.
Because an exchanger wall does not separate hot gases and water, scale in the unit is minimised. The water heater is made totally of stainless steel to work on all types of water quality. Water temperatures from C54-85 (F130-185) are available within 15-20seconds of demand. A two-pass flow of hot gas ensures a 99.7% or greater fuel efficiency where virtually all of the fuel energy is transferred to the water.
Quick payback of equipment costs can be realised in energy savings as compared to other methods of heating water.
