Centrifugal air heaters hot water or electrical supply
On the electric version, the regulations are different:
Reminder of the regulations
Fire safety regulations Article CH 37 Electrical heater coils
Electrical heater coils placed in the air stream (whatever the capacity of the coil), must be installed in accordance with the following specifications: 1. It must not be possible to power the central and terminal coils if the fan is not operating. 2. Manual reset safety thermostats (thermal short-circuit devices) must be placed on each coil, no more than 15 centimetres upstream; these are designed to cut the power supply to the coil in 3. Electric heaters must be installed in boxes or ducts made from category M0 materials. Any components made from materials which do not belong to category M0 must be protected from direct radiation from these electric heaters. Note: The insulation on our centrifugal electric air heaters is protected against radiation by the double casing on the electric heater. radiator, electric baseboard heater, electric underfloor heating system, electric heated ceiling, electric radiant panel or other process which has received technical approval by the Central Safety Committee).
procedure. §2. This equipment must not include flames or unprotected particles from it. No accessible component part of this equipment must be at a They must also comply with the specifications of title III of the order referred to in article CH 2.
Article CH 45 Electrical equipment
Unless otherwise stated elsewhere in this regulation, electrical production and emission equipment may be installed in accessible public spaces without any power limits, provided that it is fixed, in addition to complying with any particular specifications concerned.
Article CH 44 Definitions and general information
§1. A production/emission unit is a self-contained unit which produces and emits heat in the room in which it is installed. It may be a direct combustion unit (powered by solid, liquid or gaseous fuel) or a non-combustion unit (electric convector and
Our electric SILENTHERME air heater complies with the requirements of the above-mentioned regulations.

Electro-galvanised steel sheet metal coated in a dark grey paint (RAL 7024). All panels lined with glass wool to protect against erosion. Hinged access panel to the fan motor assembly and heater.
Fan motor assembly suspended on resilient mounts
Operation in ES and S zones Type G 4 or type F 5. Operation in LS and VLS Type G 1 or type G 4.
Assembled inside the casing, silent 1 speed 3-ph 230 / 400 V - 50 Hz series, equipped as standard with PTC (positive temperature coefficient) sensor. Thermal overload protection option possible. Option: 2-speed motor ratio 1:2.
Heat exchange coil for hot water SILENTHERME
Silentherme units are equipped with high efficiency coils compatible with low temperature fluids (heat pumps, condensation boilers). Easily removable without having to remove the SILENTHERME.
Electric heater for electric SILENTHERME
Composed of shielded resistors made from finned steel tubing, fitted with double insulation. 3-PH 400 V + neutral - 50 Hz supply. Power supply to the right or left of the unit, can be changed on site.
Built with copper tubes and aluminium blades for hot water with 8 bar. Supply piping Construction: hexagonal sleeves Position: - Vertical units: to the left when looking at the unit from the front. - Horizontal units: the positions can change sides on site very quickly.
There is a wide range of assembly and connection accessories available (see primary and secondary accessories section).
