A/C Kit Universal Under-Dash Evaporator 432-100
Model: E-432-100 with 12V operation and integrated harness. This kit features a 12V dual-shaft blower, a 4-way aluminum coil, and an all-in-one cooling approach with a 12V compressor arrangement. The system delivers about 12,700 BTU with a compact 14½” L × 12½” D × 6″ H footprint, making it suitable for under-dash installation in a wide range of vehicles. It includes mounting brackets, drain hose, and an electrical harness for plug-and-play installation. Consider vehicle electrical capacity when sizing for long races or extreme heat.
Key considerations: installation space, compatibility with existing condensers, and electrical draw. This kit is designed for regular car and truck applications, with special lengths available upon request. The condenser and fan units are built to support reliable cooling under demanding conditions.
Under Dash Electric A/C Heating & Cooling 12V 10000 BTU
This 12-volt kit combines a compact evaporator, condenser, and a professional-grade electric scroll compressor for 10,000 BTU of cooling capacity. It also provides heating capability, enabling a versatile climate-control solution for variable weather. The unit is designed for energy efficiency, adjusting frequency to reduce power draw and maintain operation even when the engine is idle or off. It is suitable for cars, RVs, vans, trucks, and select hot-rod builds where space and power management are critical.
Highlights include low-noise evaporator operation (below 50 dB) and smart temperature control. Prospective buyers should evaluate battery capacity and accessory availability, as well as whether external power sources are feasible for extended events or off-grid use.
TURBRO Inverter 13.5K BTU RV A/C
Designed for RVs and larger vehicles, this TURBRO rooftop unit delivers up to 13,500 BTU of cooling with heating support. It uses an energy-saving inverter compressor to optimize efficiency and minimize noise. The unit adopts a slim 10″ profile, reducing roof drag and improving fuel economy while maintaining robust climate control. It includes WiFi and remote control for convenient adjustments and can operate across a wide temperature range from 19.4℉ to 109.4℉.
Positioning considerations: rooftop mounting requires a stable mounting surface, proper sealant, and clearance for venting. The inverter approach helps maintain performance in fluctuating loads and can be paired with a power management strategy for racing environments where electrical generation is limited.
Universal A/C Kit for Cars With Louvers 404-000
This kit features a rectangular louver arrangement with four black star louvers and a parallel-flow condenser system using micro-tube technology. Evaporator under-dash design supports 12,700 BTU with a 359 CFM airflow, and includes a 12V coil with 4 black star louvers and 10′ flex duct for flexible routing. The condenser measures 14″H x 20″L with a 0.70″ core depth. This setup is suitable for classic cars, hot rods, and custom builds where authentic styling and solid performance are desired.
Considerations include duct routing, aesthetic matching with classic interiors, and ensuring compatibility with the condenser size in tight engine bays. The kit aims to balance classic looks with modern cooling efficiency.
A/C Evaporator Assembly Under-Dash 12V Kit
This under-dash A/C evaporator kit is designed to add climate control to vehicles without factory air conditioning. It features a 12V power supply with a rated cooling and heating capacity, including a heater integration. The unit is intended for car and truck installations, offering a compact evaporator core suitable for retrofits and restoration projects. The kit emphasizes durability and straightforward wiring, enabling reliable operation in a range of environments.
Buying considerations include power availability, space for evaporator housing, compatibility with existing dash layouts, and the availability of a matching condenser and compressor for a complete system. This option is particularly relevant for retrofits and hobby builds where modernization is a priority.
Buying Guide
Key purchase considerations for race car air conditioning systems include:
- Vehicle type and space: Under-dash kits fit smaller interiors, while rooftop or slim-line units suit limited roof or cargo spaces. Measure mounting areas and ensure clearance for ducts and fans.
- Cooling capacity: Match BTU ratings to the cabin volume and climate. Higher BTU is useful for hot climates and endurance events but draws more power.
- Electrical compatibility: 12V systems draw current; confirm alternator or battery capacity to support prolonged use, especially in race environments where engine idle may occur.
- Install complexity: Plug-and-play harnesses simplify wiring, but some kits require custom brackets, plumbing, and sealing. Consider professional installation if wiring diagrams aren’t clear.
- Condenser and evaporator compatibility: Ensure components align with the compressor type and condenser design (parallel-flow or micro-tube) to maximize efficiency and reliability.
- Noise and vibration: Look for low-noise evaporators and fan assemblies, particularly for long races where cabin comfort reduces driver fatigue.
- Maintenance and serviceability: Easy-access components and readily available replacement parts help minimize downtime between events.
- Power management for off-grid use: If power is limited on-site, prioritize energy-efficient inverter-driven units and consider auxiliary power sources.
- Aesthetics and integration: For classic cars or hot rods, choosing units with compatible styling helps preserve the vehicle’s appearance while delivering modern comfort.
