CFW Series Copper-Fin Water Heaters
|
CFW series Water Heaters feature a fan-assisted sealed
combustion chamber designed to control the optimum gas/air ratio for
consistently high operating efficiency. This range is available in 3 models
giving hot water outputs of 2376, 3105 and 3564 litres per hour. Thermal
efficiencies of 94% net are offered together with ultra low NOx emissions of
9.9ppm.
Copper-Fin Heat Exchanger
The Heat Exchanger is constructed from finned copper tube, where the fins are
extruded and give a 9:1 heat transfer ratio over plain tube. This ensures rapid
response to demand enabling the unit to achieve fast recovery of hot water. The
tubes operate in a two-pass arrangement and are expanded into a gasketless
header which is built from lined cast-iron. The Copper-Fin heat exchanger
carries a 5-year warranty.

Direct Hot Water
When linked to a Direct Storage vessel the CFW series gives a reliable,
efficient supply of direct hot water, on the principle of system separation.
'On-site' storage cylinder(s) can be used and Lochinvar also offer the
LST range of energy saving storage vessels, which are designed for use
with Lochinvar Copper-Fin products.
Scale-free Operation
Each CFW unit comes complete with Bronze Glanded pump and Flow switch. The pump
gives an even distribution of heat across the heat exchanger and also ensures
than any scale is kept in suspension. Lochinvar guarantee a 'scale-free' heat
exchanger even in hard water areas. Any scale present will usually settle in
the Storage vessel, which is not harmful and can be easily cleaned. This
results in high operating efficiency for the life of the Water Heater.
All Copper System
When Copper-fin Water Heaters are installed with the
CST range of storage tanks customers benefit from having an 'all copper
system'. Copper has a better natural resistance to corrosion caused by
electrolytic action without the need for cathodic protection (magnesium
anodes). In addition to lower costs on maintenance, a longer life expectancy on
equipment can be achieved.
Diagnostic Controls
The CFW is complete with fully automatic electronic ignition and diagnostic
lights which continually monitor the major functions of the unit making it
fully compatible with Building Energy Management Systems
