8.1.1 Heat meter
Heat meters must be installed in the unit on site.
The base units are equipped with appropriate fittings (110 mm,
¾” 1.5 m³/h) for the heat meters.
Sensor retainer:
- Directly immersed
- Sensor length: 28 mm
- Diameter: Max. 5.4 mm; at the sealing point min. 5.2 mm
8.1.2 Heat exchanger operating conditions
The threaded, stainless steel soldered heat exchanger is par-
ticularly suitable for applications where water quality is critical.
