Power-Fin Continues to Raise the Bar with Internal Cascading Sequencer
by Lochinvar | 06/24/2008
|In 1986, the introduction of the innovative Power-Fin® boiler and water heater line helped establish Lochinvar Corporation as the leader in advanced hydronic and water heating technology. Now, Lochinvar is raising the bar and giving cause to celebrate 20 years of reliable Power-Fin performance, with several enhancements to the time-proven design. Advances to the Power-Fin include higher turndown ratio, a standard internal cascading sequencer, and control upgrades for easy installation, system set-up and troubleshooting. |
No More Separate Sequencer
Now standard on Power-Fin "1500", "1700" and "2000" models (Btu inputs from 1.5 million to 2 million), the new internal cascading sequencer eliminates the cost and set-up requirements of a separate third-party sequencer for installations of up to eight units. The internal sequencer simplifies creation of a cascading "lead/lag" system, in which the lead boiler or water heater controls the rotating operation and firing rate of up to seven additional units. This technology ensures optimum performance and efficiency in applications that experience broad fluctuations in demand.
Electronic Control Enhancements
In addition to the internal cascading sequencer, new control technology for enhanced reliability, installation flexibility, system control and diagnostics have been added to these Power-Fin units, including the following:
The list of Power-Fin enhancements continues with 5:1 turndown modulating performance, an improvement over the previous 4:1 turndown capability. These "5:1" units are now capable of firing from 100 percent down to 20 percent of rated input to match demand. Modulating operation helps save energy and prolongs the life of the appliance, by eliminating over-firing and excessive cycling. Additional features on Power-Fin "1500", "1700" and "2000" units include replaceable air filtration, outdoor reset on boiler models, and a built-in tank sensor on water heater models.
