Designed for American-made cars from 1928 through the mid-1970s and also compatible with some foreign and later-model vehicles, the HURRICANE system offers a balance of performance, efficiency, and ease of installation. The system’s compact design allows for straightforward under-dash installation, comparable in footprint to many factory-installed units of the era. This guide provides an in-depth overview of the key components, installation considerations, and system options for the HURRICANE system based on the information provided in the source material.
Understanding the HURRICANE System Components
The HURRICANE system is engineered to deliver both heating and air conditioning capabilities in a single, space-efficient unit. The system includes an evaporator/heater assembly that is installed under the dashboard. This unit is responsible for regulating cabin temperature by either heating or cooling the air, depending on the season and user preference.
Custom installation kits are available for a variety of vehicles, including popular models such as 1947–1972 Chevrolet and 1967–1972 Ford pickups. These kits typically include mounting plates, condenser assemblies, and switching packages. The inclusion of these components ensures that the system can be adapted to fit different vehicle layouts and mechanical configurations.
The HURRICANE system also supports multiple control options, allowing users to select the most appropriate interface based on their preferences and the vehicle’s existing infrastructure. Traditional mechanical controls, such as pull cables for defrost and heater functions and rotary knobs for blower speed and thermostat settings, are available. Additionally, electronic control options with servomotors for defrost and heater functions are also offered. These electronic versions typically come with a standard switching package that includes rotary controls for the blower switch, heater valve, defrost, and A/C thermostat. A slide control option is also available as an optional upgrade.
Installation Considerations and Vehicle Preparation
Installing the HURRICANE system requires careful preparation to ensure that the system operates efficiently and safely. One of the primary installation steps involves modifying the vehicle’s firewall to accommodate the necessary hoses. This may involve cutting small holes in the firewall to allow for the routing of refrigerant and heating lines. Similarly, the glovebox may need to be trimmed or repositioned to fit the under-dash evaporator/heater unit. These modifications should be carried out with precision to maintain the integrity of the vehicle’s interior and ensure proper sealing.
Another important aspect of the installation process is the condition of the vehicle’s insulation. For the HURRICANE system to operate at maximum efficiency, the vehicle must be well-insulated. This includes insulating the roof, firewall, and floorboards to prevent heat transfer and maintain consistent cabin temperatures. Any gaps or holes that connect the interior to the outside environment should be sealed to reduce energy loss and improve system performance.
Weatherstripping is another critical factor that affects the system’s efficiency. All weatherstrips should be in good condition to ensure that the cabin remains airtight and that conditioned air is not lost through gaps in doors, windows, or other openings. Additionally, attention should be paid to seals around the pedals and wiring harnesses, as these can also contribute to air leaks if not properly secured.
Cooling System Integration and Fan Recommendations
The HURRICANE system is not only about climate control within the cabin but also about ensuring that the vehicle’s engine remains at an optimal operating temperature. To support this, Old Air Products recommends the use of a clutch-style or six-blade fan with a shroud. These types of fans are designed to provide efficient airflow over the radiator, helping to dissipate heat and maintain stable engine temperatures.
Alternatively, an electric condenser fan can also be used. This type of fan is particularly useful in vehicles where space is limited or where traditional mechanical fans may not be feasible. If an electric engine cooling fan is selected, it is important to wire the fan to engage only when the A/C system is active. This helps to reduce unnecessary power consumption and ensures that the cooling system operates in conjunction with the climate control system.
Old Air Products offers a range of fan options, including steel fans, electric condenser fans, and electric engine cooling fans. These components can be sourced separately or included in custom installation kits, depending on the specific needs of the vehicle and the installer.
Control System Options and User Experience
The HURRICANE system offers multiple control options to accommodate different user preferences and vehicle setups. Traditional mechanical controls, such as pull cables and rotary knobs, provide a hands-on approach to temperature regulation. These controls are ideal for vehicles that retain their original mechanical features and offer a classic aesthetic.
For users who prefer a more modern and automated experience, electronic control systems are available. These systems use servomotors to control defrost and heater functions, providing a smoother and more precise user experience. The standard electronic switching package includes rotary controls for the blower switch, heater valve, defrost, and A/C thermostat. A slide control option is also available as an optional upgrade, offering a more streamlined and user-friendly interface.
The choice of control system should be based on the vehicle’s existing infrastructure and the user’s personal preferences. Vehicles that already have a modern electrical system may benefit more from electronic controls, while classic cars with traditional mechanical setups may be better suited for mechanical controls.
Compatibility and Vehicle-Specific Installation
One of the key strengths of the HURRICANE system is its broad compatibility with a wide range of vehicles. The system is designed to work with American-built vehicles from 1928 through the mid-1970s, as well as some foreign and later-model vehicles. This versatility makes the HURRICANE system a popular choice for both restoration projects and custom builds.
Installation kits are available for specific models, such as 1947–1972 Chevrolet and 1967–1972 Ford pickups. These kits are tailored to the unique dimensions and mechanical configurations of each model, ensuring a more straightforward installation process. The kits typically include mounting plates, condenser assemblies, and switching packages, all of which are necessary for a complete and functional installation.
For vehicles that are not listed in the standard compatibility range, custom installation kits can be requested or ordered. These kits allow for greater flexibility in adapting the HURRICANE system to fit the specific needs of the vehicle. Custom kits may include additional components or specialized mounting solutions to accommodate unique vehicle layouts or mechanical configurations.
Performance and Efficiency
The HURRICANE system is designed to deliver both heating and cooling performance in a compact and efficient package. Despite its small size, the system is capable of maintaining comfortable cabin temperatures in both winter and summer conditions. This makes it an ideal solution for vehicles that lack factory-installed climate control or where space is limited.
The system’s efficiency is further enhanced by its compatibility with a range of control options and cooling system components. By integrating the HURRICANE system with the appropriate fan and insulation setup, users can maximize the system’s performance and ensure that the vehicle remains comfortable in all weather conditions.
The HURRICANE system also benefits from its modular design, which allows for easy maintenance and upgrades. Components such as the evaporator/heater assembly, control system, and fan can be replaced or upgraded independently, reducing the need for a complete system overhaul.
