Heating, Air Conditioning, and Ventilation

Heating

A compact, safe, and efficient diesel fueled heater keeps the interior temperature comfortable down to temperatures well below -20 degrees F. The heater is controlled by a digital thermostat and hot air is ducted into the cabin and the bathroom. The heater aboard the LTi features multiple heat output levels ranging from 2,900 to 7,500 Btu and air flow rates of 19 – 48 cubic feet per minute. It has its own fuel pump and draws fuel from the aft 40-gallon diesel fuel tank. Both fuel consumption (.026 – .070 gallons per hour) and electrical power consumption (.67 – 2.80 amps) are minimal and plenty of fuel and battery power are available for continuous cold weather operation. Our heater draws combustion air from outside of the vehicle and exhaust gases are emitted from a muffler and exhaust pipe at the rear of the vehicle. The heater is functional at all elevations and the correct fuel to air mixture is maintained by a continuously variable altitude compensator.

Air Conditioning

A 20,000 BTU high efficiency air conditioner removes humidity and provides cool air to keep you comfortable in hot and humid weather. A digital control with integrated thermostat makes it easy to control and adjust temperature. Air is ducted to the living room and bathroom. The air conditioner can run for a period of 3-5 hours depending on conditions, before recharging is required.

Ventilation

Exhaust Fans

LTi is equipped with two built-in electric ventilation fans, located in the bunk and the bathroom, which have variable speeds, a reversible airflow switch (in or out air flow), and rain sensor. Fan speed can be controlled by manually selecting a fan speed or by setting the desired temperature and the fan will speed up at high temperature differentials and slow down as the desired temperature is achieved. The built-in rain sensor closes the dome and turns off the fan when the sensor becomes wet and the dome automatically reopens when the sensor dries. A rain sensor shut off switch and a backup manual dome open/close knob are also provided. In typical operation in low humidity environments, many owners find that the fan and open windows are more than adequate to keep the camper interior cool and comfortable.

windows

European engineered windows with integrated shades and bug screens are used throughout the LTi. Dual pane glass with inventive built-in pressure system and double glazing, these windows are suited for extreme conditions and altitudes. Integrated bug-screens and blackout roller blinds can be magnetized together and simultaneously adjusted with only one hand. The aluminum coated roller blinds block all visible light and also keep radiant energy out of the vehicle in hot weather decreasing the energy required to keep the interior cool. Top hinge mounts allow the windows to open up completely, enabling excellent ventilation and keeping the interior dry even in a light rain. A security locking handle prevents unwanted opening from the outside and provides one handed operation.

Roof Hatch

A large 36″ X 24″ roof hatch located directly over the bed opens manually to a maximum 90 degree angle to provide excellent ventilation, views of the sky, and access to the roof. The roof hatch is dual pane glass and has an integrated aluminum coated blackout shade and bug screen.
