Pentair 5001825 Brochure

Powerful, efficient, and reliable, MegaTherm
heaters are designed for commercial, institutional and large
residential pools where economical performance and rapid
heat-up are required. Available in indoor and outdoor
models, with twenty-two sizes from 500,000 to 5,000,000
BTU/h to precisely match any heating requirement.
MegaTherm is designed to deliver efficiencies as high as 82%.
Integral finned copper tubes are rolled directly into the headers, and
conformal heat exchanger baffles and an eight-fins-per-inch tubing
configuration maximize combustion heat extraction. We've also
designed MegaTherm to be simple to service. Heat exchanger
header covers are field-removable for complete inspection of tubing
and header passages, and the heat exchanger is replaceable
without disassembly of the burners or combustion chamber.
MegaTherm is design certified to the ANSI
Gas-Fired Pool Heaters. (Outdoor 500–1825 units are certified for
use without the addition of a draft diverter or external vent. Indoor
units incorporate a built-in draft diverter and require only vent
piping.) Salt water models (500–1825) are available with cupronickel
alloy heat exchanger tubes and bronze headers and header covers.
