Intelli-Fin Gas Fired Condensing Boilers

The Intelli-Fin range of gas fired, wet recuperative, condensing, high efficiency boilers is another recent addition to Lochinvar’s highly successful Copper-Fin series. There are three models in the range with outputs of 427,483 and 568kW each with a footprint of just 0.65m² making them ideal for both retrofit and new installations.

Dual Copper-Fin Heat Exchanger

Copper is one of the most efficient materials to use as a heat exchanger and at the heart of Lochinvar boilers and water heaters lies a copper heat exchanger with a substantial difference – extruded copper fin tubes that offer nine times the heat absorption of plain tubes. This means a rapid response to heat demand, a major factor in the higher net thermal efficiencies provided.

Intelli-Fin’s dual heat exchanger arrangement creates a heat trap to capture convective heat flow. Trapping this latent heat reduces heat losses, increases efficiency and saves energy.

All Intelli-Fin models carry a 10 year heat exchanger warranty.

Variable Frequency Drive

Intelli-Fin boiler’s Variable Frequency Drive increases thermal efficiencies by supplying precisely the correct amount of gas and air to the burner, minimising 'cycling' and limiting excessive heat. This results in complete combustion, increasing kW output, whilst at the same time it also adjusts to meet demand.

The Variable Frequency Drive allows Intelli-Fin to modulate down to 25% of output, responding instantly to any change in system requirements.

High Thermal Efficiencies – Low NOx Emissions

Intelli-Fin operates with net thermal efficiencies of up to 108%. As a fully recuperative boiler, high efficiencies are achieved even if system return temperature is higher than optimum.

With Ultra low NOx emissions of 31mg/kWhr Intelli-Fin is environmentally friendly too.

Alcromesh Burner With 5 Year Warranty

The aluminium/chromium alloy burner dispenses the flame through 360º improving heat transfer. Quiet operation is assured and its durability results in a 5 year warranty.

Operating Flexibility

Intelli-Fin can operate with a broad range of gas pressure and water temperature situations thanks to its intelligent controls and unique heat exchanger arrangement. This prevents nuisance 'lockout' problems in applications with varying gas pressures as Intelli-Fin can operate under low pressure supply conditions.

The dual heat exchanger preheats return water to control condensate formation.

Advanced Controls

Intelli-Fin features advanced controls which can be interfaced with Building Management Systems providing a remarkable amount of information and the ability to adapt for specific applications.

Up to 21 diagnostic points and 6 operational characteristics can be locally or remotely monitored.

Flueing Options

Intelli-Fin boilers offer a choice of three flueing options (Conventional, Vertical Balanced Flue and Balanced Flue with Horizontal Air Intake) and have extremely small flue diameters. The IFB2000CE (586kW) model, for example, has a flue diameter of just 200mm – half that of a similar output conventional unit. This makes for real savings in installation costs.
