What do I have to consider in the place of installation of the NALD250 / NALD250i? Which conditions must be met?
Principally, the light ends removal system should be installed in a well-ventilated area. The exhaust duct must safely lead into the open air and the deflagration flame arrester that comes with the system must be installed at the end. The area around this opening must be free from ignition sources.
The system is also suitable for outdoor installation. However, it should be roofed to protect it from weather, e.g. by a penthouse roof, to protect the components and the electronic circuits.
It should be connected to the flow line of the thermal oil system. The return flow in the thermal oil system can be led as desired.
With this, pay special attention to the following interface parameters:
| Connection valve – thermal oil (inlet and outlet) | Nominal diameter DN40 |
| Cooling water valves | Nominal diameter DN20 |
| Thermal oil – flow | 2 – 4 bar |
| Thermal oil – return flow | 0 – 3 bar (max. 4 bar) |
| Recommended inlet temperature | 250 °C |
| Control air | 4 – 6 bar (g) |
| Nitrogen supply | > 3 bar min. 99.0% N2 |
| Cooling water | 0,5 – 1 bar |
| Three-phase connection | appr. 5 kW |
