Features
Features
- According to the manufacturer, screw connections must be provided for the water connection; the heater must be able to be drained and vented during installation.
- According to the S&P safety note, a frost protection device must be provided which switches off the fan and, if necessary, closes a damper in the outdoor air if the air or return temperature is too low.
- To protect against contamination and loss of output, S&P recommends installing an air filter box.
- As accessories, S&P lists the PWW-N1 and PWW-N2 pump hot water controls (hydraulic unit with circulation pump, three-way mixer with 230 V actuator, shut-off valves and LHCC supply air temperature control); the matching unit for each type is shown in the table.
- Curves for temperature rise and pressure drop and the dimension drawing are given in the data sheet.
Note on variants
Note on variants
The "Model" selection shows the S&P type: the number after IBW is the size matching the duct connection in the table; the suffix -2, -3 or -4 distinguishes the output levels within a size. For IBW-400-4, IBW-450-2 and IBW-450-4, the data sheet does not list a matching pump hot water control.
