ENY-SP and ENY-S Versions - Construction features of the main components
1 ENY-SP version external structure
made of hot-dip galvanised steel sheet panels painted in RAL 9003 and satin finish obtained with epoxy paint dried
in oven at 180 °C; the side panels are insulated with a 25 mm thick padding, while the inspection cover is completely
removable and is insulated with a 30 mm thick padding.
ENY-S version external structure
made of hot-dip galvanised steel sheet panels painted in RAL 9003 and satin finish obtained with epoxy paint dried in
oven at 180 °C; the inspection cover is completely removable and is insulated with a 30 mm thick padding.
2 EPDM fan access closure
3 Polyethylene EPE filter access closure
4 Electric defrosting pre-heater
Hot filament electric heater with reinforced metal lining, controlled by PWM signal (only versions with integrated electric
heater).
5 High efficiency filters compliant with Standard ISO 16890;
The filters have the following features:
-ePM
1
55% - F7 class for the supply air;
-ePM
10
50% - M5 class for the extract air.
6 ABS air distribution connections for inlet/outlet air flows
7/11 Extract air (7) and air supply (11) electric fan
consisting of:
• Permanent single-phase
synchronous EC motor.
•
High efficiency ABS fans
with backward-curved blades.
• ABS
Motor/fan housing
.
8 High efficiency static heat recovery unit
with PET counterflow exchange plates. The reachable efficiency obtainable may be higher than 90% because they ensure
counterflow heat transfer between two air flows at different inlet temperatures. The static heat recovery units do not
feature moving parts and guarantee high reliability and safe operation.
In order to increase the efficiency of the heat exchanger, the plate surfaces feature special swirlers.
9 Main by-pass damper
made entirely of ABS and motorised with a Valemo actuator.
10 Secondary by-pass damper
consisting of a steel blade and motorised with a Valemo actuator.
12 T-EP control
