The Problem Every Truck Driver Faces

Truck drivers spend long hours on the road. During breaks, they need to rest in their cabins. But resting in a hot truck cabin is not easy. Many drivers keep the engine running to power the air conditioner. This causes three big problems:

1. High Fuel Costs: A truck idling for 6 hours daily burns 3.5 liters of fuel per hour. At $1.50perliter,thiswastes$1.50perliter,thiswastes3,150 every year.

2. Engine Damage: Idling for hours wears out engine parts faster. Repair costs can reach $5,000-$5,000−10,000 over 5 years.

3. Legal Issues: Many cities ban unnecessary idling. Fines range from $100to$100to1,500 per violation.

A Vethy parking air conditioner solves all these problems. It cools the cabin using battery power, not the engine.

How Vethy Parking ACs Work: Simple but Effective

Most parking coolers only lower the temperature. But Vethy systems do two things better:

1. Cool the Air: Removes heat using compressor technology.

2. Remove Humidity: Pulls moisture from the air so sweat can evaporate.

Why This Matters:

• At 90°F (32°C), dry air feels like 84°F (29°C) if humidity is below 50%.

• At the same temperature but 70% humidity, it feels like 100°F (38°C).

Vethy units keep humidity under 60%, making 80°F (27°C) feel comfortable.

Vethy Parking AC Models: Detailed Comparison

We offer four models for different needs. Below are full technical specs:

1. Vethy VBPSO3  (Best for Small Trucks)

Key Benefits:

• Fits trucks with roof heights under 10 feet.

• Uses standard R134a refrigerant (easy to find).

2. Vethy V4000 (Heavy-Duty Cooling)

Key Benefits:

• Cools large sleeper cabins up to 300 sq.ft.

• Built-in overload protection for hot climates.

3. Vethy VSO1 & VSO2 Pro (Quiet Operation)

Key Benefits:

• R32 refrigerant reduces global warming impact by 70% vs R134a.

• "Eco Mode" cuts power use by 30% during nighttime.

Step-by-Step Installation Guide (With Pictures)

Tools You Need

1. Basic Tools:

• Drill ($30-$30−50 models from DeWalt or Makita)

• Screwdriver set (Phillips and flathead)

• Wire strippers (10-18 AWG capacity)

• Multimeter ($20-$20−40 models from AstroAI)

2. Special Tools:

• Vacuum pump ($150-$150−300 models like Robinair 15500)

• Flaring tool kit ($50-$50−80 for copper pipes)

• Manifold gauge set ($80-$80−120 for refrigerant checks)

3. Materials:

• Insulation foam tape (1/2” thickness)

• 6mm² or 10mm² copper wire (length depends on truck size)

• Drain hose (1/2” diameter PVC)

Installation Process

Step 1: Mount the Indoor Unit

1. Choose Location:

• For roof-mounted units (VBPSOB/VSO1), measure 16” from the front edge.

• For wall-mounted units (V4000), center it on the rear cabin wall.

2. Cut the Hole:

• Use a hole saw bit matching the unit’s size (e.g., 14” for VSO1).

• Sand edges to prevent metal cracks.

3. Secure the Unit:

• Apply butyl tape around the hole for waterproofing.

• Bolt the unit down with M8 stainless steel screws.

Step 2: Connect Refrigerant Pipes

1. Bend Copper Pipes:

• Use a pipe bender tool. Never bend by hand—it causes kinks.

• Minimum bend radius: 4x pipe diameter (e.g., 1/4” pipe needs 1” radius).

2. Flare Pipe Ends:

• Cut pipes to length with a tube cutter.

• Make 45-degree flares using the flaring tool.

3. Vacuum the System:

• Connect gauges to service ports.

• Run the vacuum pump for 20 minutes to remove moisture.

Step 3: Wire the Electrical System

1. Connect to Batteries:

• For 12V systems: Use 6mm² wire if the cable run is under 10 feet.

• For 24V systems: 4mm² wire works for runs up to 15 feet.

2. Add a Fuse:

• Install a 50A fuse within 12” of the battery.

• Use waterproof fuse holders in humid areas.

3. Test the System:

• Turn on the AC and check voltage drop with a multimeter.

• If voltage drops over 0.5V, upgrade to thicker wires.

Real-World Test Results

We tested Vethy ACs in Arizona summer heat (115°F/46°C):

Key Findings:

• V4000 cools fastest but uses more power.

• VSO2 Pro is best for drivers who prioritize quiet operation.

Maintenance Checklist

Follow this schedule to keep your AC running 10+ years:

Daily:

• Wipe dust off vents with a microfiber cloth.

Monthly:

• Wash air filters in soapy water. Let dry 24 hours before reusing.

Every 6 Months:

• Check drain hoses for clogs. Use a wet/dry vacuum to clear debris.

Every 2 Years:

• Recharge refrigerant if cooling slows down.

• Tighten all electrical connections.

Troubleshooting Common Issues

Problem: AC blows warm air.
Solution:

1. Check refrigerant pressure (should be 60-80 PSI on low side).

2. Look for oil stains around pipes—this indicates leaks.

Problem: Water leaks inside cabin.
Solution:

1. Ensure drain hose slopes downward 1/4” per foot.

2. Pour 1 cup of vinegar through the drain to clear algae.

Problem: Fuse keeps blowing.
Solution:

1. Replace 50A fuse with a 60A fuse if using long wire runs.

2. Clean battery terminals to reduce resistance.
