Horizontal construction, in-line connection by circular taps fitted with a seal. Possibility of adapting the connections on site.
Access to filters, exchanger, coil, and fan from the side, bottom or top.
Ø1 / 2 '' drain for condensate evacuation.

Exchanger

Aluminum plate heat exchanger, counter current, high efficiency, low pressure drop.

Motorized bypass

Delivered assembled, installed on the fresh air network.
By-pass 100% with shutter for closing the air passage on the exchanger when the bypass is open, to take full advantage of free cooling.
230V single-phase, all-or-nothing servo-motor.

Motorization

Double inlet fans, action turbine, built-in motor, mounted IP 55 electrical box.
AC motor with integrated thermal protection:
- CAD HR FIRST 04/07: 4 speeds, single phase 230V, 50Hz, IP 20 class F,
- CAD HR FIRST : 3 speeds, single phase 230V, 50Hz, IP 20 class F,
- CAD HR FIRST 33: 3 speeds, single phase 230V, 50Hz, IP 20 class B.

Filters

M5 (ePM10 50%) during extraction.
F7 (ePM1 70%) on the introduction of fresh air.

DI post-heating electric coil

Connected to the regulation, it allows the temperature of the blown air to be regulated.
Equipped with safety thermostat with automatic reset (set point 50 ° C) and manual reset (set point 65 ° C).

DC hot water coil

2-row coil, made up of copper tubes with aluminum fins on a galvanized steel frame, copper manifold, threaded connection tube.

Electric antifreeze coil (DD)

Placed on the fresh air before the exchanger, avoids the risk of freezing on the exchanger.
Raised, wired and controlled by the regulation.
Separate power supply, connection to a specific external box fitted with a proximity switch.
Safety thermostat with automatic reset (set point 50 ° C) and manual reset (set point 65 ° C).
