TJ8300 / TJ8500General Description

The cooler is located inside the collecting table.

The cooler’s function is to cool the water that flows through the UV lamp head.

The ambient temperature should be 15°C - 35°C.

The water circulates through the UV lamp head and the cooler.

The water flow pressure is 2.5 - 3.5 bar.

Within the cooler, the distilled water flows from the water container, through the radiator, which cools it, and then is pumped towards the UV lamp head.

TJ8300 / TJ8500Water Container (Cont.)

The water container contains 50 liters of distilled water with 0.5% of corrosion inhibitor and 1 unit of microtreat.

The water circulates through the cooler and the UV lamp head.

The purpose of the water (float) sensor is to alert the system if the water level is low.

If the water reaches the low (threshold) level, the system turns off the lamp power.

TJ8300 / TJ8500Radiators

The purpose of the radiators is to cool down the warm water that returns from the UV lamp head.

The fan removes the heat from the cooler unit.

Cooler

TJ8300 / TJ8500Water Pump (Cont.)

The pump circulates the water through the UV lamp head and the container, via the two radiators.

The thermal switch is set to 70°C and protects the system against high temperatures. If the temperature of the inlet water (into the radiators) reaches 70°C, the system turns off the UV lamp.

The water flow pressure is 2.5 - 3.5 bar.
