NF Group X700 12/24/48/60/72 Voltage Rooftop Parking Air Conditioner

To keep drivers well-rested and contribute greater safety on the road, our powerful rooftop air-conditioning system NFX700 ensures pleasant temperatures and humidity, creating an ideal climate with the electric parking cooler system for trucks, buses and vans. Our compressor-driven system is filled with refrigerant HFC134a and is connected to the 12/24V vehicle battery.

Installation in the existing roof opening is very simple and time-saving. High-quality components set up a high quality standard for parking coolers and ensure a long life with a minimum expenditure on maintenance. The electric parking cooler reduces engine idling times and therefore saves fuel. The low-voltage cutoff ensures that the engine will start.

NFX700 Automotive Air Conditioning System – Technical Overview

The NFX700 is a compact, vehicle-integrated air conditioning system engineered for diverse mobile platforms. Its modular architecture and voltage-flexible design support seamless integration across conventional and electrified vehicle segments. Key technical features include:

1. Multi-Voltage Compatibility: Available in 12 V and 24 V configurations for light-duty commercial vehicles—including light trucks, medium-duty trucks, passenger sedans, and construction machinery with limited roof aperture dimensions; and in 48–72 V variants optimized for battery-electric platforms such as passenger EVs, low-speed elderly mobility scooters, enclosed electric sightseeing vehicles, electric tricycles, material-handling equipment (e.g., electric forklifts), and municipal service vehicles (e.g., electric sweepers).

2. Non-Invasive Roof Integration: Designed for retrofit installation on vehicles equipped with factory sunroofs—requiring no structural modification, drilling, or interior trim removal. The system maintains full OEM aesthetic integrity and enables reversible, tool-free disassembly at any time.

3. Automotive-Grade Internal Architecture: Features a standardized, modular internal layout compliant with ISO 16750 (road vehicle environmental conditions) and SAE J1455 (vibration testing). This ensures robust thermal performance, electromagnetic compatibility, and long-term operational stability under real-world driving conditions.

4. High-Performance Enclosure: Constructed from aerospace-grade aluminum alloy and reinforced polymer composites—offering exceptional strength-to-weight ratio, zero deformation under static load (tested to 150 kg distributed load), UL94 V-0 flame retardancy, UV resistance, and thermal stability up to 120°C.

5. High-Efficiency Scroll Compressor: Utilizes an oil-free, hermetically sealed rotary scroll compressor—delivering superior volumetric efficiency (>92%), low mechanical vibration (≤2.5 mm/s RMS per ISO 10816-1), acoustic performance (<58 dB(A) at 1 m), and extended service life under continuous duty cycles.

6. Aerodynamic Housing Design: Incorporates a contoured baseplate with optimized curvature matching standard vehicle roof contours—enhancing visual integration, minimizing aerodynamic drag (validated via CFD simulation), and improving rainwater runoff management.

7. Condensate Management System: Integrated condensate drainage interface enables direct connection to vehicle chassis drain lines—eliminating interior moisture accumulation and ensuring drip-free operation under all ambient humidity conditions.
