Seawater is highly corrosive, so the pipeline components used in seawater are required to have strong corrosion resistance, and the all-plastic flow switch solves the problem of corrosion resistance and stability well.

Current situation

▶ At present, the sea water source heat pump and pool heat pump will consider the problem of corrosion, equipment manufacturers will be in the design of the water pipe suitable material selection, usually use UPVC or PPR pipeline, but the traditional target water flow switch is not corrosion resistant can not be used, some equipment manufacturers because they can not find the right water flow switch can only use plastic pressure switch instead. As everyone knows, the pressure switch cannot sense the change of water flow, and the problem is still their own. There are also some manufacturers because they can not find the right flow switch in the unit does not install the flow switch, the problem is left to the user, the user often buy the traditional target flow switch installed on the above, the result is not much time the target flow switch bellows will corroded and lead to water leakage, which is the irresponsible performance of the manufacturer.

Advantages of using WFS22/27 series plastic flow switches for sea water/pool heat pumps

▶ The water flow switch uses high-strength PPO material to solve the problems of corrosion resistance, pipe pressure and water temperature of the plastic flow switch.

▶ Flow switch with a scale baffle, users can easily get their desired size.

▶ The flow switch is designed with a low pressure drop baffle, which increases the effective lift provided to the customer.

▶ The flow switch is equipped with a UPVC bonding connector for easy connection to UPVC pipes.

▶ The flow switch is designed with magnetic switch or micro switch and can be used for small and large currents.

▶ The flow setting value of the flow switch can be adjusted by itself, and the flow control is accurate.

Application of anti-corrosion water flow protection solutions for sea water source/pool heat pump

▶ At present, our solution is launched in 2006, the successful application of more than 100,000 sea water/pool heat pump units, and most of the units are exported abroad, the stability of the flow switch is high, the current program has been successfully adopted by foreign equipment manufacturers, completely solve the problem of corrosion resistance of the water switch.
