AC-powered, 12V, and split heat/cool systems for the patient compartment of Type I, Type II, and Type III ambulances. Option to include the patented Danhard Air Shield air curtain.
Danhard designs and manufactures HVAC systems for the patient compartment of Type I, Type II, and Type III ambulances. Based in Dallas, Texas, Danhard has served ambulance manufacturers since 1963. Our systems are used by AMR NextFleet across 100+ locations nationally, by ASV for their full ambulance line, and by Osage Ambulances.
Our 125V shoreline systems are the most common choice for Type I and Type III ambulances. These complete, self-contained AC-powered systems include a compressor, condenser, evaporator, control box, and all wiring. They run on AC electrical power from an onboard generator or shoreline connection.
The modular architecture allows the evaporator to be mounted in the location that best fits your ambulance design. Common mounting positions include inside the squad bench (most common, minimal impact on storage space), under the CPR seat, inside the ALS cabinet, and under the attendant chair.
Every AC-powered system includes Danhard's proprietary pre-wired control box with 15 feet of cable for each component. The installer routes the pre-terminated cables to each component and connects them. Competitor systems historically required 50+ individual terminal block connections. This dramatically reduces installation time and wiring errors.
In ambulance pull-down testing, Danhard's AC-powered systems often cool the patient compartment to the required temperature in 50-60% of the maximum allowable time.
Our 12V cooling systems tie into the ambulance's OEM engine-driven compressor for cost-effective patient compartment cooling. Every 12V system is configured specifically for the vehicle: Danhard's engineering team evaluates your available mounting space, blower motor requirements, and condenser needs to recommend the right package.
Split systems position the cooling evaporator at the top of an interior cabinet with a separate heater at baseboard level. This arrangement delivers superior temperature distribution: heat rises naturally from the floor while cool air is delivered from above.
For cold-climate ambulance operations, the split-system approach can deliver meaningfully better patient compartment comfort than a single combination unit. This configuration is preferred by ambulance manufacturers serving northern U.S. and Canadian markets where heating demand is high.
Danhard manufactures integrated heat and cooling units that handle both functions in a single compact assembly. The combination coil provides cooling via the refrigerant circuit and heating via engine coolant tie-in. These units are more compact than split systems, making them the right choice when mounting space is limited or when moderate heating and cooling performance is sufficient.
The Air Shield is Danhard's patented air curtain system designed specifically for mobile vehicle applications. It creates a wall of high-velocity air across the ambulance doorway to maintain interior climate control and keep insects out when doors open for patient loading and unloading.
Danhard has been the primary supplier to AMR NextFleet since its inception. We serve 100+ AMR locations nationally for remounts and service parts, with flexible blanket orders that match their unpredictable production schedule.
ASV has relied on Danhard as their primary HVAC supplier since 2018. The relationship started with a single blower sale and grew based on availability, performance, and personal service. ASV has grown from one shift to two full shifts during the partnership.
Tube-and-fin construction on every coil and condenser, rotary compressors for AC-powered systems, and 95%+ U.S.-sourced components. On the rare occasion a warranty claim is needed, we do whatever is required to make it right.
Our lead engineer, Mark Nation, has 30+ years of specialty vehicle HVAC experience. He guides every customer through system selection at no charge, ensuring the right system for your ambulance configuration.
