Match Load And Capacity
With this versatile stand, you can stack Copper-Fin2 and Energyrite Pool Heaters to achieve the perfect Btu/hr capacity for each application.
For example, a facility needs a Copper-Fin2 pool heater with a total capacity of 1.6 million Btu/hr. Instead of installing an oversized CPN1801 unit or a smaller CPN1441 model, now you
can combine two units – CPN991 and CPN651 models– to exactly match the facility’s needs.
Plus, the total footprint of this combined system is just over 10 inches wider that the CPN651 unit alone, making it smaller than either the CPN1801 or CPN1441 model. All thanks to the Lochinvar Multi-Stack Frame.
No Assembly Required
Lochinvar’s Multi-Stack Frame is fully factory assembled and shipped in one piece. The frame is welded using square steel tubing by certified welders ensuring integrity for the life of the frame.
Added System Benefits
This modular design provides two other important benefits. First, it allows for system turndown for greater efficiency when demand is lower. Second, it ensures against system failure by utilizing two independent units.
For residential and light commercial needs or commercial applications of up to 4 million Btu/hr, the Multi-Stack Frame gives greater flexibility without a significant increase in stack size or overall system dimensions.
Once you’ve determined a facility’s requirements and the exact models needed, utilize the charts provided to calculate total system dimensions.
Two Lochinvar 990,000 Btu/hr Copper-Fin2 pool heaters stacked for a total capacity of almost 2 million Btu/hr.
