December 15, 2006 -
With BTU inputs from 1.5-2 million, Power-Fin 1500, 1700, and 2000 models feature internal cascading sequencer for creating lead/lag system in which lead boiler or water heater controls rotating operation and firing rate of up to 7 additional units. They include 2-line, 16-character LCD, 0-10 Vdc BMS input, and 3-pump control capability. With 5:1 turndown modulating performance, systems can fire from 100% down to 20% of rated input to match demand.

Lochinvar Continues to Raise the Bar with Internal 8-Unit Cascading Sequencer
Lochinvar Introduces New Enhancements to the Power-Fin®
LEBANON, TN - December 2006 - 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:
o 2-line, 16-character LCD readout of set-up, status and diagnostic information displayed in easy-to-understand words instead of potentially confusing codes.
o 0 - 10VDC BMS input, for easy integration into Building Management Systems.
o 3-pump control capability for systems requiring a boiler pump, system pump and DHWP pump.
o Optional software for PC or Pocket PC, offers expanded capability for recording, tracking and analyzing system data to fine-tune operation for maximum performance and troubleshooting.
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.
Other Built-In Advantages
All Lochinvar Power-Fin boilers and water heaters incorporate the features and intelligent designs that have set the standard for quality for over 20 years. These include a gasketless copper-fin tube heat exchanger that delivers money-saving 87 percent thermal efficiency, compact "filing cabinet" configuration for a small footprint, and the flexibility of six different venting options including two-pipe direct vent.
