MegaTherm

High Performance Gas Fired

Commercial Pool Heater

Powerful, efficient, and reliable, MegaTherm® pool 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.

Indoor

Sizes 2000 – 5000

For Indoor Pools Model I

1. Calculate the surface area of the pool in square feet.

2. Refer to the selection chart for either an indoor or outdoor heater.

3. Find the closest square footage in the 10° F (6° C) Temperature Difference column, and the heater models which correspond to it. For normal conditions, Pentair recommends using the 10° F Temperature Difference columns; this will provide a temperature increase of approximately 6° F per 24 hour period.

NOTES: 1. For high altitude pools, reduce the surface area figures shown in the charts by 4% for each 1000 ft. above sea level. (No derating is necessary up to 2000 ft. above sea level.)

2. Pentair maintains a policy of continuous improvements and therefore reserves the right to change specifications without notice.

3. Sizing for outdoor pools is based on 3

⁄2 mph average wind.

MegaTherm

High Performance Gas Fired Commercial Pool Heaters

The Perfect Combination of Accurate Control, Efficiency, and Long Life

MegaTherm® is packed with performance features designed specifically for the commercial, institutional, and large residential pool market. The primary/secondary pump and control (Models 500–1825) feature an electronic controller with a solid state sensor and adjustable differential for accurate temperature control. Inlet water is preheated to eliminate condensation, and a constant velocity in the heat exchanger increases tube life. The diverter valve has been eliminated in the pool circulation line, resulting in lower installation and operating costs. And, inlet and outlet thermometers with ±1% accuracy allow precise set-up and temperature rise monitoring.

Additional Design Advantages Include:

• Control system includes automatic temperature control, temperature

limit, gas pressure regulator, redundant electric gas valve, water flow sensing, electronic flame safety supervision and manual gas shut-off valve. The standard control system operates on 24 VAC with a 120 VAC power supply. Standard units are intermittent (spark) ignition.

•Working pressure of 160 psi complies with Section IV of the ASME

Boiler and Pressure Vessel Code. Units are registered with the National Board of Boiler and Pressure Vessel Inspectors.

Pressure relief valve is ASME® rated and is selected to provide

•

discharge capacity in excess of unit heating input.

•

Combustion chamber is cast refractory with a 2000° F (1093° C)

working temperature.

• Burners are atmospheric type constructed of AISI alloy 430 (models

500–1825) or AISI 439 (models 2000–5000) stainless steel.

• Chassis and jacket parts are of galvanized steel meeting ASTM

Standard for G90 coating. Exterior is finished with acrylic paint, thermoset at 325° F (163° C).
