Evaporator is the unit that mounts inside the vehicle on the firewall.
This component contains a tube and fin coil similar to a radiator
liquid refrigerant and engine coolant travel through.
blower forces air across the coil, through duct hose and out vents.
An important aspect of evaporators is the coil size.
Since a coil can only process a specific amount of air at any
it is important that the coil size be adequate for the interior
size of the vehicle.
(i.e. larger vehicles require larger coils/evaporators)
Our Elite Series Evaporators should be mounted
where the hose adapters point upward.
This is important as mounting the unit in any other orientation
will Not Allow the condensation
to properly drain form the unit.
When installing the Thermostat Capillary Tube into the unit it
Should Not be pushed to
the bottom of the Evaporator core.
If the Capillary tube is installed this way the thermostat will
sense the condensation water temperature
rather than the Evaporator Coil temperature causing the Evaporator
to freeze up.
Hot Rod Air uses the largest A/C and Heater Pass Coils available
on the market today for maximum performance.
Evaporator size should Not
be decided by the amount of area available behind the dash.
The size of the unit used Should
be based upon the amount of capacity needed
to keep your Car or Truck comfortable on the hottest days.
The performance of the evaporator can be enhanced by the following:
Insulating the vehicle completely from outside heat.
Including upper cowl section, firewall, headliner, door panels,
inner kick panels, etc..
Seal all window and door openings as well as cowl vents with quality
Slightly Tinting the glass of the vehicle to reduce ultraviolet
rays from entering the vehicle.
(This will also preserve your interior for longer life as well).
If you are running a smooth firewall,install the Evaporator prior
to painting by welding the mounting brackets to the inner firewall
to maintain the smooth appearance in the engine compartment.
For fiberglass cars,the brackets can be attached to the firewall
by simply fiberglassing the brackets in.
