Description
NIVTANK suction lance with level detector for pool and spa installations
The NIVTANK is specially designed for safe suction and accurate detection of the liquid level in chemical drums. Thanks to its combination with a motor pump or peristaltic pump, this system is ideal for pool and spa water treatment. This prevents unwanted air bubbles, blockages and interruptions in the dosing of chlorine or pH correcting agents.
- Suitable for jerrycans and barrels of 20-30 liters
- Equipped with check valve to prevent backflow.
- Level detection prevents air intake and blockages
Intake lance for chemicals
The sturdy suction lance is easily attached to a standard jerry can with Mü 61 thread. Thanks to the integrated ball check valve, liquid does not flow back when disconnecting the line or a faulty pump. The lance is adjustable in height and therefore usable for different canister sizes.
Smart level detector
The built-in level detector activates an "empty signal" as soon as the vessel becomes empty. This signal is activated when the float sinks, providing the user with an immediate notification. In combination with the BL122 and BL132 dosing systems, the notification can even be forwarded via the Hanna Pool app. This way you always know in time when the chlorine or acid tank needs to be replaced and prevent problems with green pool water.
Prevent clogging and crystallization
An empty vessel can cause air in the lines, leading to crystallization and clogging in injectors. Thanks to the NIVTANK, this problem is prevented, keeping dosing operations reliable and continuous.
Chemical resistance
The NIVTANK resists a wide range of pool chemicals and acids, including:
- Sodium hypochlorite (NaClO) up to 15%.
- Hydrochloric acid (HCl) up to 20%
- Sulfuric acid (H2SO4) up to 38%.
- Sodium hydroxide (NaOH) up to 27% (pH-plus)
- Polyaluminium chloride (PAC)
- Organic chlorine products up to 10%
