Here's another FAN-tastic example of the variety we carry.

A couple of weeks ago, we featured a compact defrost fan.

Today, we're stepping things up with something designed to move a whole lot more air.

The BT3-0155 16-inch Reversible 12V Fan is built for applications where airflow is critical. Its reversible design gives you the flexibility to either push or pull air, making it a great fit for a wide range of cooling and ventilation needs across heavy-duty equipment.

Because every machine is different, the right fan for the job is too.

Why choose the BT3-0155?

✅ Large 16-inch diameter for increased airflow
✅ 12V operation
✅ Reversible to push or pull air as needed
✅ Durable construction for demanding environments
✅ Ideal for cooling, ventilation, and custom applications

💡 Did You Know?

Not every fan serves the same purpose. Some are designed for defrosting a windshield, others circulate cab air, while larger reversible fans like this one are built to move significant volumes of air for cooling and ventilation. Choosing the right fan can make a noticeable difference in HVAC performance and equipment reliability.

At BTRAC, we stock everything from compact defrost fans to large reversible fans, blower motors, blower assemblies, and plenty of other COOL parts to keep your equipment working comfortably.

A couple of weeks ago, we talked about the condenser.

Today, let's talk about its equally important partner: the evaporator.

The easiest way to remember the difference?

The condenser gets rid of heat.

The evaporator absorbs heat.

The Red Dot 76R4920 Evaporator Coil is the component inside your HVAC system that actually removes heat from the cab air. As warm air passes across the cold evaporator fins, the refrigerant inside absorbs that heat, leaving you with the cool air coming through your vents.

Meanwhile, the condenser (which we featured a couple of weeks ago) takes that heat outside the cab and releases it into the atmosphere.

It's a continuous cycle:

❄️ Evaporator = Absorbs heat from the cab

☀️ Condenser = Releases that heat outside

Neither one can do its job without the other.

Why choose the 76R4920?

✅ Genuine Red Dot replacement evaporator coil
✅ Efficient heat absorption for dependable cooling
✅ Built for demanding heavy-duty HVAC systems
✅ Restores cooling performance when replacement is needed
✅ Designed for long-lasting service

💡 Did You Know?

The evaporator also removes humidity from the air. That's why you'll often see water dripping underneath a machine after the A/C has been running. It's simply moisture that condensed out of the cab air, just like a cold drink "sweats" on a hot summer day.

At BTRAC, we stock both evaporators and condensers because both are essential to keeping your HVAC system performing its best.

Not every repair needs the whole assembly.

Sometimes... you get lucky.

When a blower quits working, it doesn't always mean the entire assembly has reached the end of its life. If the housing, wheels, and mounting components are still in good shape, replacing just the blower motor can get your HVAC system back in business while saving both time and money.

That's exactly why we stock components like the Red Dot 73R0454 Blower Motor.

Whether you're repairing a failed blower or rebuilding an existing assembly, we carry the individual parts needed to keep your equipment moving air- not just complete assemblies.

Why choose the 73R0454?

✅ Genuine Red Dot replacement blower motor
✅ Restore airflow without replacing the entire assembly
✅ Ideal for repairing worn or failed blower motors
✅ Built for heavy-duty mobile HVAC applications
✅ Backed by BTRAC's extensive inventory of HVAC replacement parts

💡 Did You Know?

Many blower assemblies are made up of several serviceable components. If only the motor has failed, replacing just that component can often be a practical and cost-effective repair while allowing you to reuse the rest of the assembly.

At BTRAC, we don't just stock complete blower assemblies. We also carry blower motors, blower wheels, housings, and many other replacement components so you can repair what actually failed, not replace what didn't.

Why choose the 71R4010?

✅ Genuine Red Dot replacement quality
✅ Restores a clean, factory appearance
✅ Easy installation
✅ Built for years of daily use
✅ One of many k**b styles available from BTRAC

💡 Did You Know?

Control k***s may look similar, but they come in several different shaft styles and diameters. Choosing the correct k**b ensures a secure fit and smooth operation while keeping your controls looking like they should.

If you're not sure which one fits your application, our team is happy to help.

Remember that 10-terminal blower switch we featured a couple of weeks ago?

Well... this is its complete opposite.

The Red Dot 71R0010 is about as simple as a switch can get.

Just two terminals.
Single Pole.
Single Throw.

No complicated wiring diagrams. No ten-wire harnesses. No wondering which terminal is number seven.

Sometimes simple really is better.

The BTRAC 71R0010 is a genuine Red Dot SPST toggle switch built for applications where reliability matters more than complexity. When all you need is a dependable on/off switch, this little workhorse gets the job done without any unnecessary extras.

Why choose the 71R0010?

✅ Genuine Red Dot quality
✅ Simple two-terminal design
✅ Single Pole, Single Throw (SPST) operation
✅ Easy installation and dependable performance
✅ Perfect for countless heavy-duty electrical applications

💡 Did You Know?

Many electrical issues aren't caused by complicated components; they're caused by simple ones that have worn out over years of vibration, dust, moisture, and thousands of operating cycles. Sometimes replacing a basic switch is all it takes to bring a system back to life.

Not every repair needs ten terminals.

Sometimes two are all you need.

BTRAC is looking for a part-time / contract web developer, but I’m really looking for a partner.

Over the last couple of years, we’ve been steadily transforming BTRAC.com from a traditional industrial website into a much larger e-commerce, marketing, and customer-resource platform.

And we’re not done. Not even close.

I’m looking for a developer who knows their way around:

🔹 WordPress
🔹 WooCommerce
🔹 Elementor
🔹 PHP / CSS / JavaScript
🔹 APIs and third-party integrations
🔹 Payment, shipping, ERP, and e-commerce integrations
🔹 Technical SEO, site speed and performance

This would be part-time / contract work as needed, with the opportunity to grow alongside what we’re building.

Remote work is absolutely fine, but ideally, I’m looking for someone based in Wisconsin or Minnesota. I want the flexibility to collaborate remotely most of the time while still being able to get together in person when a project, integration, or larger initiative benefits from working side by side.

But technical ability is only part of what I’m looking for.

I want someone who is passionate about this stuff.

Someone who sees a website problem and wants to understand why it is happening. Someone who gets excited about making something faster, cleaner, easier to use, and more scalable. Someone who will challenge my ideas when there’s a better way to accomplish something.

Basically, I’m looking for a technical partner who can match my level of obsession with making BTRAC.com better.

We’re an established company in the heavy-duty mobile HVAC industry, but digitally, we’re building something much bigger than where we started.

If that sounds like the kind of project you’d enjoy, send me a message or reach out to BTRAC.

And if you know someone who fits that description, please tag them or send this their way.

Listen... I know you probably think I'm crazy.

Who talks about cab heaters twice in the middle of August?

Hear me out.

We've been operating in the Midwest for 50 years, and if there's one thing we've learned, it's that our weather changes fast. Before you know it, those hot August afternoons will be replaced by frosty mornings, and the last place you want to discover your heater isn't working is on the first big freeze.

A couple of weeks ago, we featured one of our compact 20,000 BTU cab heaters. Today, we're stepping things up.

The BTRAC BU-1000-0-12 delivers 35,000 BTUs of dependable heat while maintaining a compact, single-blower design. It's an excellent choice when you need more heating capacity for larger cabs or colder climates without moving to a more complex heater configuration.

Why choose the BU-1000-0-12?

✅ 35,000 BTUs of dependable heat
✅ Compact single-blower design
✅ 12V operation for a wide variety of equipment
✅ Ideal for agriculture, construction, forestry, utility, and specialty vehicles
✅ Built to keep operators comfortable when temperatures drop

💡 Did You Know?

Cold operators aren't just uncomfortable; they're less productive. A properly heated cab helps improve comfort, reduces fatigue, and can help keep windows clear for better visibility throughout the workday.

After 50 Midwest winters, trust us on this one. The best time to replace a heater isn't after it quits; it's before winter ever gets the chance.

Think all A/C compressors are basically the same? Think again.

Just because two compressors move refrigerant doesn't mean they're built for the same job.

The BTRAC BT5-2521214 is a Valeo TM-31 24V compressor designed for heavy-duty mobile HVAC systems that demand high cooling capacity and long-term reliability. Built around the proven TM-31 platform, it's engineered to handle continuous operation in vocational trucks, buses, construction equipment, and other demanding applications.

Unlike smaller compressors, the TM-31 offers increased displacement and cooling capacity, making it an excellent choice when operators depend on consistent cab comfort during long hours in extreme heat.

Key features include:

✅ Heavy-duty Valeo TM-31 compressor platform
✅ 24-volt operation for commercial equipment
✅ High-capacity design for demanding HVAC systems
✅ PV8 serpentine clutch with 152 mm diameter
✅ Direct-mount configuration for OE-style fitment
✅ Horizontal O-ring fittings for clean hose routing and dependable sealing

💡 Did You Know?

A compressor that's too small for the application can struggle to maintain cooling during high ambient temperatures or extended idle time. Heavy-duty systems often require larger displacement compressors like the TM-31 to keep operators comfortable throughout the workday, not just when the machine is moving.

At BTRAC, we help customers match the right compressor to the application, because choosing the correct replacement is just as important as replacing the failed part.

Remember the FEFF208 filter we featured a couple of weeks ago?

Today, let's take a look at the system it was designed to protect.

The BTRAC BT8-2004-4 (Sy-Klone RCF2038) is much more than a filter housing. It's a complete RESPA® CF2 Fresh Air Pressurization System engineered to provide operators with cleaner air in some of the harshest working environments.

Here's how it works:

The RCF2038 continuously draws in outside air, removes fine airborne contaminants through its RadialSHIELD® filter, and delivers clean, filtered air into the cab while maintaining positive cab pressure. That positive pressure helps keep dust, smoke, pollen, and other contaminants from entering through door seals, windows, and other small openings.

The benefits include:

✅ Cleaner air for operators
✅ Positive cab pressure that helps keep contaminants outside
✅ Longer HVAC maintenance intervals and extended filter life
✅ Built for demanding applications including forestry, construction, mining, agriculture, and waste handling

💡 Did You Know?

The RCF2038 uses Sy-Klone's powered precleaning technology to eject debris before it reaches the filter. That means less contamination reaching the filter element, helping extend filter life while maintaining consistent airflow.

Whether you're outfitting a single machine or an entire fleet, investing in clean cab air is investing in your operators.

Yesterday we talked about the receiver drier... today let's talk about what comes next.

A receiver drier and an expansion valve are teammates.

The receiver drier cleans and stores the refrigerant.

The expansion valve decides how much refrigerant gets into the evaporator.

The Red Dot 71R8300 Expansion Valve is essentially the traffic cop of your A/C system. It meters the flow of high-pressure liquid refrigerant entering the evaporator, ensuring just the right amount enters to provide maximum cooling.

Too much refrigerant, and the evaporator can't do its job efficiently.

Too little, and you won't get the cooling performance you're looking for.

The expansion valve constantly adjusts to keep the system operating at peak performance.

Why choose the Red Dot 71R8300?

✅ Genuine Red Dot quality
✅ Precisely meters refrigerant flow
✅ Helps maximize cooling efficiency
✅ Built for demanding heavy-duty HVAC systems
✅ Direct replacement for the correct application

💡 Did You Know?

The receiver drier and expansion valve work hand in hand.

The receiver drier removes moisture and filters contaminants before the refrigerant reaches the expansion valve. That's important because even tiny amounts of debris or moisture can clog or damage the valve, affecting cooling performance.

That's also why it's recommended to replace the receiver drier whenever the system has been opened for repairs. Protecting the expansion valve starts long before the refrigerant reaches it.

At BTRAC, we stock a wide variety of expansion valves for everything from common replacements to specialized heavy-duty applications, helping ensure you get the right fit for your machine.
