Transit Van Conversion HVAC

12V evaporator and condenser packages for transit van conversions and Type II ambulances. Space-efficient systems designed for van-based specialty vehicles, with free engineering support and same-day shipping on in-stock units.

Danhard provides 12V evaporator and condenser packages for transit van conversions, including Type II ambulances. Our systems are designed for the space constraints and budget requirements of van-based specialty vehicles. ASV and AMR NextFleet — two of the largest ambulance remounters in the country — both use Danhard HVAC systems in their transit van programs.

12V Evaporator and Auxiliary Condenser Packages

Transit van conversions require HVAC systems that fit tight compartments and integrate with existing OEM infrastructure. Our approach centers on 12V evaporator units paired with auxiliary condenser packages that tie into the OEM compressor. This configuration works with the factory compressor and refrigerant system, avoiding complex modifications to the powertrain.

We stock multiple evaporator capacities and condenser sizes to match the cooling load of your specific patient compartment, cargo area, or crew cabin.

Danhard Engineering Consultation

Before we recommend a system, our team evaluates available mounting space, OEM alternator capacity, and cooling load requirements specific to your vehicle platform. This consultation is provided at no charge to all prospective OEM customers.

What Makes Transit Van Installations Different

Fewer Mounting Options

Transit vans offer fewer installation positions than a Type I or Type III box ambulance. Roof mounting, side wall mounting, and under-seat configurations are all possible, but each requires careful planning around door clearance, structural members, and passenger access. We review your specific van layout before making a recommendation.

Tighter Electrical Headroom

Many van platforms carry alternators rated at 100–120 amps. Adding a secondary cooling system reduces headroom for other electrical loads. We assess the full electrical demand before specifying a system, and in some cases recommend a higher-output alternator or a reduced-capacity evaporator to stay within the vehicle's limits.

Cost-per-Unit Pressure

Van-based conversions typically run on tighter program margins than large commercial chassis builds. A 12V evaporator paired with an auxiliary condenser costs meaningfully less to purchase and install than a full combination unit, which is why it's the standard choice for high-volume Type II ambulance programs.

Replacement Parts and Accessories

Danhard maintains a full catalog of replacement parts for all systems. Whether you need hoses, fittings, controls, blower motors, or complete evaporator assemblies, we stock the parts you need and ship most orders the same day.

This inventory strategy helps keep your van conversions in service and your warranty costs under control.

Frequently Asked Questions

What is the difference between a 12V evaporator and a 12V combination heat/cool unit?
A 12V evaporator provides cooling only and requires tying into the OEM compressor for refrigerant circulation. A combination heat/cool unit includes heating capability. For transit van conversions, we typically recommend 12V evaporators paired with auxiliary condensers because they are more space-efficient and work well with the existing OEM system.
Can you help me determine if a 12V system will work for my van platform?
Yes. We evaluate available mounting space, OEM alternator amperage, and cooling load requirements for your specific vehicle. This engineering consultation is provided at no charge.
What alternator amperage is required for a 12V HVAC system?
Most of our 12V evaporator systems draw 30-50 amps during compressor engagement, depending on the specific configuration. Some van platforms have lower alternator output, which can be a limiting factor. We will work with you to assess whether your platform can support the load or if we need to reconfigure the system.
Do you supply replacement parts for transit van systems?
Yes. We stock a full catalog of replacement parts for evaporators, condensers, hoses, fittings, and controls. Most orders ship the same day.
