The Eagle Sun™Closed (Indirect) “I” System is designed to accommodate climates where freezing weather occurs more frequently. Instead of water flowing through the collector, an antifreeze solution is circulated. A heat exchanger is located within the storage tank. This maximizes the heat transfer from the antifreeze solution to the coldest water in the storage tank.

The “I” System is known as an indirect pumped system because the heat transfer solution, i.e. antifreeze, is pumped through the collector in a closed loop. It never comes in direct contact with the potable water in the storage tank. The closed loop includes the collector, connecting piping, pump, expansion tank, and heat exchanger. In this design, the large heat exchanger coil wraps around the perimeter of the storage tank.

The differential control determines when the pump should be activated and deactivated.

Storage Tank Features

Model– 80 gallon capacity

R-Foam Insulation— R-17.30 Rigid Polyurethane foam insulation for optimized operation. Electric control is covered by fiberglass insulation for easy accessibility.

Tank—Eagle Sun water heater tanks are made with exacting care. The tank surface is coated with an exclusive porcelain formula and fused to the solid steel shell at 1600O. The result is a smooth, tough, glass like lining. Tank is designed and tested to withstand 300 PSI hydrostatic test pressure of 150 PSI U.L. Standard.

Collector Feed and Return are located for easy access and simple connections. 3⁄4” NPT female connections at inlet and outlet.

Cold Water Inlet brings cold water to tank bottom to prevent mixing with already heated water.

Anode Rod protects inner tank. Additional opening in top pan for easy access to anode rod.

Cold Water Inlet, Hot Water Outlet, Relief Valve and Anode Rod are at top of tank for easy access and fast, economical installation.

Thermostat Opening—1⁄2“ NPT opening for accurate sensing of water temperature.

Heat Exchanger—Copper tubing wrapped around and secured to the tank. Double-wall, vented design for positive leak detection and foamed in place with R-Foam for efficiency.

NOTE: To prevent corrosion, proper pH levels in transfer fluid must be maintained. Refer to operation and maintenance manual.

Improved Electrical Junction Box (for 1⁄2” and 3⁄4 “ conduit) placed above heating element for easy installation. No spot welds used.

Direct Immersion Heating Element is completely immersed – all the heat goes into the water. Nickel Chromium heating coil imbedded in magnesium oxide and sealed in a tinned-copper tube. Although in direct contact with water, the ends are sealed to prevent entrance of moisture., Elements are changed, should the need arise, by screwing into special tank flanges.

Automatic Temperature Control Thermostat keeps stored water at desired temperature.

High Temperature Limit automatically and safely cuts off power to the element should excessive temperature occur.

Every system comes complete with the following:

n Solar Collectors
n Storage Tank with Heat Exchanger
n Water Reservoir
n Differential Termperature Controller
n Fluid Circulating Components
n Circulation Pump
n Installation Manual
n Mounting Hardware
