Roof top DC Electric Air Conditioning System
These electric rooftop units are a great solution for any peace of mobile equipment with a cabin, being completely electric DC they simplify the install and still produce a great result.
Available in both 12volt & 24volt they definitely have a place in the market.
They are a modified Red Dot unit, and completely self-contained – Evaporator – condenser & compressor in one unit
- Ease of installation
- If an off engine compressor install is not an option this is a great alternative
- Simple wiring
- Diverse application
- Environmental friendly
Minimum system requirements:
12 volt Compressor draw (amps) @12v
27A – 55A depending on speed selected and condensing pressure (psi)
Example: Condensing pressure @ 150psi on 35 day
Low speed 2000rmp = 27A
Medium speed 3350rpm = 35A
High speed 4000rpm = 55A
Compressor has a low voltage, high voltage & quick voltage fluctuation cut out function, if the voltage changes very quickly compressor will stop and not resume operation until stable voltage has been maintained.
Low voltage cut out (wont operate below) @12v = 11v
High voltage cut (cannot exceed) @12v = 14.2v
24 volt Compressor draw (amps) @24v
17A – 50A depending on speed selected and condensing pressure (psi)
Example: Condensing pressure @ 150psi on 35 day
Low speed 2000rmp = 15A
Medium speed 3350rpm = 30A
High speed 4000rpm = 50A
Compressor has a low voltage, high voltage & quick voltage fluctuation cut out function, if the voltage changes very quickly compressor will stop and not resume operation until stable voltage has been maintained.
Low voltage cut out (wont operate below) @24v = 18.5v
High voltage cut (cannot exceed) @24v = 29v
*These are the approximate draw figures, the under load figures will be specific to cabling size, condensing efficiency, alternator output & ambient temp. Units must be wired in by a licensed Auto electrician and only commissioned with R134a refrigerant from a licensed technician with a Arctik AU number*
