Product Introduction

• Structure: A compact, flat-tube type evaporator constructed from high-efficiency aluminum tubes and fins, with integrated refrigerant lines and a service port. It features a lightweight, corrosion-resistant design optimized for maximum heat absorption in the confined cabin space.

• Performance: Converts liquid refrigerant into a low-pressure vapor, absorbing heat from the cabin air to provide cooling. The high-density fin design and aluminum construction ensure rapid heat transfer, while the integrated lines and port simplify maintenance and refrigerant recharge.

Core Function

1. Heat Absorption: Converts liquid refrigerant to vapor, removing heat from the cabin air to deliver cooling.

2. Efficient Cooling: High-density fins and flat-tube design maximize surface area for rapid heat transfer.

3. Compact Design: Optimized for installation in the limited space of the truck’s cabin HVAC housing.

4. Durability: Corrosion-resistant aluminum construction withstands vibration and temperature extremes.

Evaporator 812W61942-0047 for Sinotruk Sitrak — Factory-Direct AC Cooling Component

When your Sitrak truck’s cabin air conditioning system loses its chill, the evaporator is almost always the silent culprit. The Evaporator 812W61942-0047 is a genuine-spec replacement part engineered specifically for Sinotruk Sitrak heavy-duty trucks. Built to absorb heat efficiently and maintain consistent cooling airflow inside the cab, this evaporator keeps drivers comfortable even during the longest hauls under scorching conditions. At Mettlead, we supply this part directly from our China-based warehouse — which means you get factory-direct pricing without sacrificing quality or delivery speed.

Why This Sinotruk Sitrak Evaporator Matters for Your Fleet

An evaporator does more than just cool air. It directly affects driver comfort, cabin humidity control, and ultimately fleet uptime. Here’s what the 812W61942-0047 evaporator delivers once installed:

• Optimized Heat Absorption: The multi-layered aluminum fin design maximizes surface area, allowing refrigerant to absorb cabin heat rapidly and evenly.
• Corrosion-Resistant Construction: Made from high-grade aluminum alloy, this evaporator resists moisture-related corrosion — a common failure point in humid operating environments.
• Exact OEM Fitment: Manufactured to match the original Sinotruk Sitrak specifications, so installation is straightforward with no bracket modifications or adapter kits needed.
• Consistent Cooling Performance: Maintains stable refrigerant flow distribution across all tubes, which prevents hot spots and ensures uniform cold air output from the vents.
• Extended Service Life: Strict quality control during production means fewer premature failures, reducing replacement frequency and long-term maintenance costs for your fleet.

In other words, this isn’t just a cooling component — it’s a reliability investment that pays back through reduced downtime and happier drivers.

Application — Which Sitrak Trucks Use the 812W61942-0047 Evaporator?

This evaporator was designed to serve the HVAC systems across several Sinotruk Sitrak series cab configurations. Specifically, you’ll find it fitted in:

• Sitrak C7H — Long-haul tractor units where drivers spend extended hours in the cab and rely heavily on climate control.
• Sitrak C5H — Medium-to-long-distance logistics trucks that operate in diverse climate zones.
• Sitrak G7 — Next-generation heavy-duty models with updated cab comfort systems.

Whether your fleet operates across the deserts of the Middle East, the tropical roads of Southeast Asia, or the variable climates of Africa and South America, this evaporator is built to cope with high ambient temperatures and continuous duty cycles. Drivers running 10+ hours daily deserve consistent cooling — and fleet managers deserve parts that don’t fail prematurely.

Customer Case Study — Evaporator 812W61942-0047 Bulk Order for East African Fleet

Earlier this year, a fleet maintenance company managing over 200 Sinotruk Sitrak trucks in Kenya reached out to us. Their existing evaporator supplier had inconsistent quality — nearly 15% of units arrived with damaged fins or incorrect port alignments, causing costly installation delays.

After sourcing the Evaporator 812W61942-0047 from Mettlead, they placed an initial trial order of 50 units. Every single evaporator passed their incoming quality inspection. Fitment on their Sitrak C7H fleet was confirmed exact-match, and the lead time from order confirmation to port delivery was just 18 days.

The result? They’ve since placed three repeat orders and consolidated all their Sitrak HVAC parts sourcing with us. Their procurement manager noted that consistent part quality eliminated the rework costs that previously ate into their maintenance budget.

Frequently Asked Questions — Evaporator 812W61942-0047 Sinotruk Sitrak

Is the Evaporator 812W61942-0047 an original Sinotruk part or aftermarket?

This evaporator is manufactured to OEM-equivalent specifications, meaning it matches the original 812W61942-0047 in dimensions, material composition, and performance output. It’s a direct-fit replacement that installs identically to the factory-original unit on Sinotruk Sitrak trucks.

What causes a Sitrak evaporator to fail, and how can I tell mine needs replacing?

The most common failure mode is internal corrosion caused by moisture accumulation over time, which leads to micro-leaks in the refrigerant tubes. Symptoms include weak cooling output even after recharging refrigerant, a musty smell from the vents (indicating mold growth on a compromised evaporator surface), or visible frost buildup in uneven patterns. If your Sitrak’s AC blows warm despite having correct refrigerant levels, the 812W61942-0047 evaporator is the likely component to replace.

Can this evaporator handle high-temperature environments like the Middle East?

Absolutely. The aluminum alloy core and anti-corrosion surface treatment are specifically chosen to perform under extreme ambient temperatures. Trucks operating in 45°C+ environments place enormous thermal load on the AC system, and this evaporator’s parallel-flow fin design ensures efficient heat exchange even under those conditions.

What’s the typical lifespan of the 812W61942-0047 evaporator?

Under normal operating conditions and with proper AC system maintenance (clean cabin air filters, correct refrigerant charge, no contamination in the system), this evaporator typically lasts 3 to 5 years or more. Harsh dusty environments may shorten this slightly if cabin filters aren’t replaced on schedule.

Do you provide any warranty on this evaporator?

Yes. All Mettlead-supplied evaporators come with a quality assurance guarantee. Specific warranty terms depend on order volume and agreement type — please reach out to our sales team for exact coverage details.

Can I order just one unit, or is there a minimum order quantity?

While we primarily serve B2B buyers and distributors, we remain flexible on order quantities. Whether you need a single piece for an urgent repair or 500 units for warehouse stocking, contact us and we’ll provide a competitive quote tailored to your volume.
