Pro ENY-SHP-170 Version - Construction features of the main components
1 Pro ENY-SHP-170 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.
2 EPDM fan access closure
3 Polyethylene EPE filter access closure
4 Electric defrosting pre-heater
Electric heater hot filament 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 extracted air.
6 ABS shanks for inlet/outlet flow connection
7/11 Extract air (7) and air supply (11) electric fan
consisting of:
• Permanent single-phase
synchronous EC motor
.
•
High efficiency PA fans
with backward-curved blades.
•
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 By-pass damper with 2 louvers driven by the same motor
10 Main power board
