Closed Loop Solar Water Heating System

Detailed Product Description

Closed Loop Solar Water Heating System

Model:
GM100S GM150S GM200S GM300S GM400S GM500S
GM100D GM150D GM200D GM300D GM400D GM500D

Descriptions:
The system pump heat-transfer fluids (usually a glycol-water antifreeze mixture) through the solar water heater. Heat exchangers transfer the heat from the fluid to the water that is stored in tanks. Heat exchangers or twin coil solar tanks prevent contamination of the household water. Closed-loop glycol system are popular in areas subject to extended subzero temperatures because they offer good freeze protection. It is the preferred option for extremely cold areas.

Feature:
1. Simple Installation, No Maintenance, Effective operation
2. Easy Retrofitting To Existing systems
3. Suitable for single and multiple solar heating Application systems,
4. Preferred option for extremely cold areas and questionable water quality.
5. Incoming potable water is routed to the solar storage tank
6. Double-walled Copper Coil heat exchangers in storage tank prevent contamination of household water.
Closed Loop System Running Principle:
1. The controller will switch on the pump when the temperature at the collector sensor is higher than the return temperature by at least the pre-selected(delta T) amount.
2. The pump circulates a heat-transfer liquid around the loop.
3. Heat from the collector is transferred to the domestic wat
4. Er through the heat exchange coil in the tank.
5. With the pump running, if delta T is not met, the pump will switch off.
6. When a preset tank temperature is reached at maximum setting temperature, the controller switches off the pump
7. The check valve(non-return valve) prevents heat from the tank rising towards the collector if the tank is warmer(e. G. At night).
