DESCRIPTION
Pre-heating solar water heater supplies warm water through a coiled copper pipe heat transfer in big water tank. Cold water go into and out of copper coil, it absorbs energy and become warm, users ger clean and constant warm water for shower and other functions.
FEATURES:
● High wind load strength and High snow load strength
CARACTERÍSTICAS:
● El agua caliente sale con alta presión.
● Funcionamiento completamente automático
● El agua se puede calentar rápidamente.
● Combinó el intercambiador de calor en el sistema sin presión
● Sin riesgo de corrosión o depósitos de sarro
● Económico en comparación con otros sistemas presurizados
● Hay disponibles opciones de refuerzo eléctrico o de gas
● Alta resistencia a la carga de viento y alta resistencia a la carga de nieve.


How it works?
Step 1:
Solar glass tubes absorb solar radiation and converts radiation to heat energy.
Step 2:
As to the thermosiphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
Step 3:
The cold water goes into the copper coil inlet, be heated by the hot water of the inner tank, and go out from the outside of copper coil
Step 4:
People do not use the hot water directly from the water tank, they use the hot water from the inside of copper coil.
Cómo funciona?
Paso 1:
Los tubos de vidrio solar absorben la radiación solar y convierten la radiación en energía térmica.
Paso 2:
En cuanto al principio del termosifón, el agua caliente de los tubos va al depósito de agua, mientras que el agua fría del depósito desciende a los tubos.
Paso 3:
El agua fría entra en la entrada del serpentín de cobre, se calienta con el agua caliente del tanque interior y sale por el exterior del serpentín de cobre.
Paso 4:
Las personas no usan el agua caliente directamente del tanque de agua, usan el agua caliente del interior del serpentín de cobre.
APPLICATIONS
homeuse use shower, washing,etc
project warm water supplyment
public buildings warm water supplyment
Advantages of pre-heating solar water heater:
1. Clean water is ensured , since water does not contact big water tank.
2. Lifespan is longer than normal solar water heater, big water tank has less possibility of rust.
3. Warm water supply at a constant flow and stable temperature
4. Big water tank is not fill with new water time to time, empty drying can not happen, it reduces the probability of maintenance.
5. Less scale may happen in big water tank, because there is not frequent change of water supply

Pre-heat solar geyser is a classification of the solar water heater system.
Categories: Pressure type, Vacuum tube type
This model has a special copper coil heat exchanger in the inner tank. The coil copper pipe can bear 6 bars pressure, water tank is non-pressuried.
The water in the tank is used as the heat transfer medium, rather than using it directly. The obvious advantage is with water supplier, which can supply cold water into the tank automatically; It can be connected to pressurized system.
Our Solar Collector (SPA-58/1800-20) Heat Pipe Solar Keymnark has been tested and improved over time, so that it can be used in a wide range of applications. Our values are to create customer value, care for employee growth and achieve win-win situation. No matter what kind of company it is, it has its responsibilities and missions, because this is the goal and direction of all employees' work.
