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 heaters are 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 the MegaTherm
heater 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 heaters are design certified to the ANSI
®
Z21.56 Standard for 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 header covers.
STANDARD FEATURES
• Reliable operation on natural or propane gas.
• Electronic ignition.
• Built-in draft diverter (indoor models) simplifies installation.
• Flow switch standard on all models.
• Integral pump assures proper water flow (Models 500–1825).
• Automatic gas valve.
• Stainless steel burners, with slide-out burner tray for easy maintenance and long life (Models 500–1825).
• Galvanized steel jacket with acrylic finish for strength and durability.
• High temperature refractory firebox liner to 2000° F for greater efficiency.
• Easy-to-service header flanges.
• Corrosion-resistant glass- lined headers.
• Integral lined copper tube heat exchanger for higher efficiency.
• Electronic temperature control for accuracy. (Models 500–1825; model configuration varies slightly by size.)
THE PERFECT COMBINATION OF ACCURATE CONTROL, EFFICIENCY, AND LONG LIFE
The MegaTherm heater 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).
Integral flow control valve on models 2000–5000 accepts flows up to 300 GPM.
