In 1986, Lochinvar® introduced the Power-Fin® boiler to a market looking for a more efficient hydronic heating solution. Almost four decades later, the market is looking again. LECTRUS™ commercial electric boilers bring yet another solution to Lochinvar’s already diverse product portfolio. Whether your goal is decarbonization or creating a dual fuel heating system, LECTRUS can help accomplish those goals. Designed, engineered and assembled at Lochinvar’s Lebanon, Tennessee headquarters; LECTRUS is not just another electric boiler. LECTRUS is an electric boiler built with the same expertise and quality that continues to recognize Lochinvar as an industry leader in commercial hydronic heating.
NO ONE BRINGS IT ALL TOGETHER
LIKE LOCHINVAR
The LECTRUS’ modulation control board rotates the operation of each element bank based on the average runtime of the bank, helping to ensure equal cycles across contactors but also equal runtime for all heating elements.
LECTRUS FEATURES
- MAIN CONTROL BOARD
- MODULATION CONTROL BOARD
- LOW WATER CUT-OFF PROBE
- ROBUST INCOLOY SHEATHED 15kW HEATING ELEMENTS
- 3” NPT ASME INSPECTION OPENING
- CONTACTORS
- FUSE BLOCKS
LECTRUS features Lochinvar’s popular SMART SYSTEM™ control platform. The same interface that Lochinvar boilers have used for years brings a familiar experience to customers; simplifying product set up and troubleshooting. Cascade up to eight LECTRUS boilers or use Front End Loading functionality with LECTRUS and other condensing or non-condensing Lochinvar boilers.
THE OPTION YOU NEED – IS STANDARD
Triac Board(s)
While other electric boilers require expensive upgrades or a different series
altogether, LECTRUS features a fully modulating control as standard
construction. Every LECTRUS boiler is built with a modulating element bank,
which allows for precise temperature control, reduces contactor cycles and
helps extend component life.
VESSEL ENGINEERING AND MANUFACTURING EXPERTISE
To date, Lochinvar has built over 410,000 ASME rated vessels and heat exchangers including:
- Custom Hi-Power electric water heaters from 120-2,500 gallons
- Custom storage tanks up to 5,000 gallons
- Power-Fin’s copper heat exchanger
- CREST fire tube heat exchanger
Leveraging engineering and manufacturing expertise makes Lochinvar uniquely qualified to construct the heart of LECTRUS boilers.
ASME CONSTRUCTION ON EVERY MODEL
The LECTRUS boiler features two vessel sizes; 17 gallon vessel for 15-90kw
and 32 gallon vessel for 105-150kw models.
