Alpine Racing
Design
This large external unit was designed to utilise the latest technology for optimum energy savings across its components:
- A thermal wheel with 74.9% efficiency (ErP)
- Duplex supply & extract fans with
- EC motors with 90 & 89% efficiency respectively
- Backward curved impellors with 78 & 77% efficiency respectively
- Controls to customise the running time
Our flexible design approach meant the unit configuration could be arranged as uniquely specified by the client: fresh air intake louvres on the front and back of the unit; exhaust louvre on the right; and supply and return connections on the top.
Additional heating and cooling components were added: an LPHW frost heater and a DX reverse cycle heat pump with both summer and winter modes.
Filtration grades were selected to meet the specified standards: supply filters classified ISO16890-Coarse 80% EN779 G4 & ISO16890 ePM1 >55% EN779 F7, and extract filters classified EN16890 ePM10 >65% EN779 M5.
Unit Construction
The robust structure of the unit has an aluminium pentapost frame on a channel base, with coated steel panels. Portholes were included for easy inspection of fan and filter sections, and panels are hinged for maintenance access.
A weatherproof construction will help to ensure a long service life:
- A double-pitched lid
- Powder coating
- Louvres on the fresh air intake and exhaust outlet including birdmesh guard
Manufacturing and Flatpacking
The unit was first constructed at our in-house facility in Andover, in a number of sections to break down its large structure. At the client’s request, the unit was supplied in flatpack form for easier manoeuvre and placement on site and reconstructed in place.
