Air Filtration & Pressurization

Air filtration and pressurization are key components of HVAC systems that help maintain indoor air quality by removing airborne contaminants using filters. Pressurization helps control the direction of airflow and prevent infiltration of outdoor pollutants.

We offer two different Air Filtration & Pressurization Solutions. Both systems continually supply fresh filtered air into the cab creating a positive pressure inside a properly sealed cab. This over-pressure pushes clean air out leaks in the positive pressure side of the system, rather than allowing contaminated air to enter. The indoor air quality is critical to providing a healthy and productive work environment and whether it’s agriculture, construction, mining or waste management, operators spend a great deal of time in the cab of their equipment. 

Cab pressurizers are highly effective at removing particulate as well as vapors and fumes. The filter element can also be customized to target specific contaminates present where your equipment is working. A differential pressure gauge or electronic pressure control system are available to measure the difference in pressure between the inside and outside of the cab

Cab Filtration Solutions

The system incorporates Enginaire’s proven air pre-cleaner, with a patented in-line filter to make a highly efficient pressurizer that ensures clean filtered air. The unit combines a pre-cleaner with our proven VLR air filter system to give you a very efficient self contained filter air pump. As air is drawn into the air conditioner, the components remove large dirt particles with the built in centrifugal pre-cleaner.

The air is then filtered and blown into the air conditioner intake duct with our self contained air pump. By having a positive pressure on the incoming air chamber, the air conditioner can do it’s job easier with less power required. Even when the air conditioner is not being used, the clean air from the ECP is blown into the cab creating a positive pressure. This prevents dirt from entering the cab through leaks in it’s doors and other spaces.

Enginaire’s Cabaire™ uses it’s own high pressure air pump not a fan to deliver a high volume of dual filtered air into your enclosure which then has a positive air pressure on the inside. When the enclosure has a positive pressure, dirt is forced out of the doors, windows, and other unsealed areas instead of being drawn into the enclosure. You stay clean, your electronics and other instruments stay clean, while you “breathe easy”.

So whether you’re looking for a solution for smaller applications like Tow motors, Agriculture or gigantic machinery in Mining operations, Arctic Traveler Canada has a solution for your application. Call or visit us today for more information and see what 60 years of excellence can do for you.

Diagnosis and Troubleshooting A/C Systems

Troubleshooting A/C systems can be done easily, if the proper components and steps are followed. A/C system performance is achieved with many components working together to provide cab comfort for the driver and passengers. The item that receives the most attention is the Compressor. The compressor operates as the “pump” of the system, keeping the refrigerant circulating and increasing the refrigerant’s pressure.

All compressors have two sides: Suction and Discharge. The refrigerant is drawn into the compressor’s suction side as a cold-low pressure vapor and then is compressed, thus raising the refrigerant pressure and temperature. The high pressure-high temperature vapor refrigerant is then pumped out of the compressor’s discharge side to the condenser.
As the compressor moves the refrigerant through the system, the refrigerant oil also moves with the refrigerant.

AC System - Replacement HVAC Parts & Supplies - ATC I 1-800-295-4156


Why are compressors removed?

1) Loss of a refrigerant charge – Cold refrigerant entering the compressor on the suction side coming from the evaporator provides cooling to the compressor. With a loss of refrigerant, the compressor overheats. Also, with a loss of refrigerant, the oil is not returned back into the compressor and eventually the compressor will run dry. AC Compressors - Replacement HVAC Parts & Supplies - ATC 1-800-295-4156

2) Contamination – Particles found inside the system will cause internal damage to your system. These particles can cause blockage at the condenser, expansion valve or damage to the internal parts of your compressor. Contamination must be removed from the system by using the correct flushing procedures.

3) Misdiagnosis – Change the wrong part is a common procedure in repair A/C failures. The system must be properly diagnosed before changing parts and pieces.

What are the most common causes of compressor failures?

1) Low Refrigerant Charge AC Compressors - Replacement HVAC Parts & Supplies - ATC 1-800-295-4156
2) Leaks with the System
3) Contamination in the System
4) Lack of Lubrication
5) Clutch Failure due to System Failure
6) Blockage or Restriction within the system
7) Insufficient Condenser Cooling

What happens if a compressor continues to run under a low refrigerant charge?

1) Overheating of the compressor occurs. AC Compressor - HVAC Replacement parts & Supplies - ATC I 1-800-295-4156
2) Refrigerant oil circulation slows down and returns very little back to the compressor
3) Without proper lubricant and refrigerant charge, the compressor will “lock-up” and destroy the compressor.
4) The critical low charge point is reached when the system has 50% or less of the recommended refrigerant charge.
5) Disabled or Malfunctioning switches that allow the compressor to run in a low charge situation.

With mechanical reliability at all-time highs, heavy-duty A/C components rarely fail. In fact, components mainly fail because of the contaminated refrigerant oil and general lack of preventive maintenance. Proper maintenance increases operating time and saves money by identifying concerns before they become problems.

How to inspect an A/C Compressor

Take these steps to inspect an A/C compressor to ensure it really needs replacing before you pull it from a heavy-duty vehicle:

1. Is The Compressor Rotation Smooth?
With the vehicle off, turn the compressor shaft with a 14-mm socket. If you feel grinding or hanging as you rotate the shaft, it’s probably due to broken components within the compressor. If the rotation is smooth, move on to Step 2.

2. Is The Coil Getting More Than 11.5 Volts?
Take a reading with the engine running and the clutch engaged. If there’s insufficient voltage, get to work on that. Otherwise, move on to Step 3.

3. Is The Coil Resistance Between 2.8 And 4.4 Ohms?
Any resistance outside this range will prevent the clutch from engaging or will cause used circuits to open. If the answer is yes, continue to Step 4.

4. Is The Compressor Able To Produce 350 Psig Or More?
If not, leave the compressor where it is. The system may have a low refrigerant charge because of a leak that needs repair, or a high-side blockage that limits refrigerant flow to the compressor.

Tech Tips from Red Dot
” We see lots of compressors that are returned fully functional and therefore not warrantable.
Get the diagnosis right. Inspect an A/C compressor before you pull the component from the vehicle.”

How to troubleshoot your A/C Electrical system

Tech Tips from Red Dot

On any vehicle and virtually any A/C system, electrical problems are among the hardest to troubleshoot. If you suspect an electrical problem with the A/C system, here’s a two-stage inspection routine that virtually anyone can do with no special tools or skills:

1. Inspect Electrical Connections

As you perform a visual inspection under the hood (cab) and/or at the rooftop condenser, take a moment to check all electrical connections both visually and by feel. Make sure all leads and wires are properly supported and securely connected, and that there’s no corrosion or grime on the leads or connectors.

2. Check Electrical Current Flow and Device Functions

Perform the following steps to check the current flow and electrical device functions:

  • Turn on the ignition. 
  • Turn on the A/C system. This will power the thermostat and clutch. If it does not come on, use the A/C mode switch to check the leads to the switch. You should hear a “click” from the thermostat and hear the clutch drive plate “snap” against the clutch pulley. 
  • Check fuses. If all the connections are clean and tight and there’s still a failure, check the fuses in-cab as well as in-line.
  • Check A/C clutch engagement. Since you can’t see and may not hear the clutch engage, get out and look at the clutch. If it’s engaged, you will see that the drive plate is against the pulley and not slightly spaced from it. If you aren’t sure the clutch is engaged, look for the lead wire connector near the clutch. Break and close that connection. The clutch will disengage and engage again.
  • Test blower speed operation. Some systems have a common switch that turns on the air conditioner and powers the blower motor. Test blower speed operation by adjusting this or the separate blower control switch. Feeling the air flow from the ducts or note blower sound (speed) changes.
  • Inspect roof-mounted condensers. Don’t forget to inspect roof-mounted condensers and A/C units for dirt and debris. Be sure the condenser fan(s) are working properly and all parts and electrical connections are securely fastened. The roof-mounted condenser fans may come on when the system is turned on. Like the thermostat and most clutches, the normal on-off cycling action cannot be observed until the engine is running with the A/C system on.
Once your visual inspection is complete, talk to a qualified A/C technician about what you found. Your troubleshooting efforts will be rewarded with a speedier repair and perhaps a lower repair bill.

Quick Heater Service Tip from Reddot
  • When the status is “heater fan doesn’t work,” check the ground connection for rust, paint, grime, or some other obstruction at the terminus.
  • If the motor doesn’t have a ground wire, its mount serves as a ground connection. Make sure nothing impedes the mount’s ground path.
  • Use a multimeter to make sure you’re getting full voltage to the motor. Once you know the voltage is adequate, you can then look for worn brushes, dirty squirrel-cage fans, damaged fan blades, and other more typical motor problems.

A/C Hose repairs

Replacement A/C Hose lines don’t have to be from the Original Manufacturer!

How To Repair A/C Hose – In the past, it was difficult to find a supplier capable of doing AC hose repairs, but with today’s wide selection of high-quality fittings and hose, your replacement could be right here at ATC. The Air Conditioning System provides the desired cabin temperatures to ensure operator comfort. The AC hose is used to effectively transfer both liquid and gas between the components and should be inspected for leaks and either repaired or replaced ASAP, to ensure the system continues to perform as expected.

Today, many hose sets come with metal tube sections, some of which we offer. If no suitable fitting is available, using a hose to replicate the metal tube is the next best thing.
Our experience suggests using Aeroquip hose and E-Z Clip may hold an advantage over crimp fittings for replacing metal tubes. Aeroquip EZ Clip & Hose fitting is a simple option for making or repairing Air Conditioning hose lines on heavy-duty trucks, agricultural, construction and other industrial applications. No hydraulic equipment is needed. Rather, a simple, easy-to-use crimping plier enables quick and easy A/C Hose repairs in the field.
Each Aeroquip fitting 
comes with 2 Clips which slide over the hose and a Cage which locks into the fitting, goes through the cages and is secured with crimper pliers.

The reduced diameter hose enables tighter turns (but not right angles) without concern for “kinks” which would compromise the hose and AC system.
AC Hose Repair using Aeroquip EZ Clip Fittings and Hose is a quick solution for the quick turn around needs and mobile technicians. Providing even greater flexibility, when the E-Z Clip fitting is lubricated with a slight amount of refrigerant oil before it’s inserted into the hose, the direction/index of the fitting can be changed by rotating the fitting in the hose. Once the refrigerant oil used has dried (1-2 hours) the fitting can no longer be turned or re-indexed.

Cabin Air Filters

Cabin Air Filters – Increase A/C efficiency and Reduce dust, dirt and allergens
A relatively new feature in the heavy duty industry, the cabin air filters are often overlooked in regular vehicle maintenance. That’s unfortunate because the cabin air filter is just as important to the passengers as the engine air filter is to the vehicle and a likely cause of “A/C Not Blowing Cold“. A cabin filter processes the air that enters the passenger compartment via the vehicle’s heating and air conditioning system, increasing passenger comfort by trapping particulates, pollen, and other irritants.

For people with allergies and other sensitivities to airborne agents, the cabin filter represents a significant advance. Replacing the cabin air filter at the recommended interval or sooner, especially in areas of high particulate, allows the A/C system to run at optimal efficiency and passengers to breathe cleaner, fresher air, which makes any journey more enjoyable.

A/C Preventative Maintenance

When it comes to air conditioning, a good preventative maintenance program will increase operating time and save money by identifying concerns before they become problems. Once the hot weather arrives, implementing planned maintenance allows you to schedule repairs instead of reacting to sudden unexpected issues. A/C filters, coils, and fins require regular maintenance to ensure optimum performance and neglecting necessary maintenance results in a steady decline in performance and increased energy use. 

Filters

Clogged, dirty filters restrict airflow and reduce a system’s efficiency. When airflow is restricted, the air that bypasses the filter will carry dirt directly into the evaporator coil and reduce the coil’s heat-absorbing abilities. To ensure efficiency, routinely clean or replace filters.

Coils

The condenser and evaporator coils collect dirt over time but a clean filter helps to keep the evaporator performing well. Debris reduces air flow, insulates the coil and reduces its ability to absorb heat. Being exposed to the elements, it is easy to see the dirt collecting on the fins. Cleaning the coil fins and removing any debris around the coil will ensure optimal performance.

Coil Fins

The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into their original condition.

Remember to always use caution when performing preventative system maintenance, as ambient conditions (heat load) will increase refrigerant hose temperatures and don’t forget, having the right quality parts on hand makes all the difference.

A/C System – How a simple inspection can save

RedDot

Tech Tips From RedDot

Heavy-duty A/C system components rarely fail. In fact, the system fails the components because of contaminated refrigerant oil and general lack of preventive maintenance.

One of the best ways to improve uptime and reduce maintenance costs for the customer is to promote a basic visual check of major A/C components, hose connections, and fittings at regular intervals, like with every engine-oil change. This inspection routine has another benefit: it can generate business for your parts and service department. 

Many A/C components are consumable items. It’s more cost-effective to replace them than to repair them. So preventive maintenance is an opportunity to sell a range of OEM-quality all-makes replacement parts for the air conditioner. Here are some examples:

1. RECEIVER DRIERS

The receiver-drier’s moisture indicator provides a quick visual cue about the refrigerant’s condition: a blue dot means the refrigerant is dry; pink, white, or grey indicates acid or moisture in the system. Checking the sight glass during an oil change or any scheduled maintenance procedure means the truck can receive necessary service while it’s there in the shop, before moisture and acid damage critical A/C components and lead to a failure on the road.

2. CONDENSERS

Dust, bugs, feathers, and other debris collect on the face of fins and tubes and act as a thermal barrier, making it hard for the condenser to shed heat. Condensers also fail because of vibration, which can cause hose connections to come loose and fatigue the condenser tubing adjacent to the fittings. Every 12 months, the condenser should be cleaned (taking special care not to bend or damage the fins) and the hose connections securely clamped.

3. COMPRESSOR/CLUTCH ASSEMBLY

The compressor provides the mechanical energy to circulate refrigerant and manipulate the pressure inside the system. It’s the heart of the A/C system, and the No. 1 HVAC maintenance expense item. Excessive noise and poor cooling performance are the two most obvious symptoms that a compressor is failing. Replacing the compressor involves pulling down the system, which adds refrigerant recovery and recharge to the repair cost.

Next time you see, “A/C won’t blow cold air” on a work order, note that the repair and downtime probably could have been avoided with a simple visual inspection of the truck’s air conditioning system. Any time you change the truck’s oil, check the A/C.
