Eberspaecher’s coolant heaters work independently of the engine and thus offer a double plus: preheating the vehicle’s passenger compartment as well as the engine. The heaters are integrated into the cooling system of the engine. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air and this heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.
The Heaters for Commercial and Industrial Applications
Eberspaecher Air and Coolant heater kits can be customized to suit your specific needs. From units that are boxed for protection to controllers that can provide flexibility to your operation! These heaters are Bio Diesel Compatible and available in both 12 or 24 volts. 
AIRTRONIC D2, B4, D4, B5, D5, D8 and Echo8 Air Heaters
AIRTRONIC units range from 2 kW / 7,500 BTUs to 5 kW / 18,800 BTUs and are available with our Digi-controller, which has an internal ambient air temperature sensor for precise compartment heating. This makes it compact for a variety of location mounts.
HYDRONIC B, D, M & L Series Coolant Heaters
The Hydronics range from 12 kW/42,000 BTUs up to 35 kW/120,000 BTUs in a boxed configuration. These units have an automatic altitude compensation and are available in 12 or 24-volt models and come with accessories such as a spark arrestor. They are compact for a variety of location mounts. The M Series has multiple speeds that reduce amp draw in lower ranges.
Control Options
Easy to Operate
Eberspaecher heaters operate as miniature furnaces that are independent of the engine, utilizing the unit’s own diesel and batteries to produce heat.
Efficient
Hydronic units heat the coolant, then circulate it to warm the engine and heat exchangers to near operating temp and can be sized to provide auxiliary heat for other critical fluids. Eberspaecher air heaters heat air directly and circulate air to applicable compartments.
AIRTRONIC heaters can provide ample heat to the cab, mobile work stations, crew shelters, etc., all without idling the engine.
Productive
Using timer controls, heaters can be switched on to begin engine preheating at preset intervals, allowing operators to go directly to work upon arrival.

The most important advantages:
Espar Hydronic heaters are integrated into the cooling system of the engine and work independently of the engine, thus offers pre-heating of the engine and the vehicle’s passenger compartment. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air which heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.
Before the cold weather arrives, it’s recommended that your Espar HYDRONIC heaters receive a preseason check to ensure the heater is clean, free running and ready for a trouble-free season. Please use the recommended tools and follow the procedures as outlined in the heater manual while removing and reinstalling the different heater components.The heaters should be inspected and repaired by an Espar trained Technician, as follows:
1. Check all electrical connections from the heater to the batteries. Check for wear and abrasion along the length of the harnesses. Repair or replace the harness whenever the harness insulation is broken or damaged. Check the battery connections. Clean any corrosion at the terminals. Replace the battery terminals if the corrosion is severe. Check the fuse for corrosion and the correct rating.
2. Check all clamps and hoses. Replace as required.
3. Check the condition of the exhaust system. Check for holes and breaks in the exhaust piping. Replace the exhaust as necessary.
4. Check the fuel pump filter ‐ clean or replace it as necessary. For heaters with external fuel pumps, ensure that the mounting angle of the fuel pump is in between 15‐35o. An incorrectly mounted fuel pump may lead to excessive carbon issues. Check the fuel lines for possible leaks, loose clamps, etc. Once the entire fuel system has been checked and issues, if any, are corrected, it is advisable to do a fuel quantity check.
5. Check and clear clogged weep holes on the side of the heater body. Look for any indication of coolant leakages. If leakage is suspected then remove the cover with water pump assembly and inspect and replace “O” rings on the water pump housing. Closely inspect the heater waterjacket for leakages and replace the “O” ring between waterjacket and heat exchanger. If the waterjacket is cracked, replace it.
6. Remove and replace the glow pin screen. Make sure that the new screen is installed correctly as outlined in the repair manual for the heater.
7. Remove and check the glow pin. If it shows signs of dissimilar colour or if the glow pin is in any way distorted, replace it.
8. The coolant pump should be removed and the impeller checked for damage. Any dirt or metal particles on the impeller magnet should be removed and the cavity in the pump should also be cleaned. Please Note: coolant pumps are not covered by warranty if the vehicle’s coolant system is excessively contaminated. Refer to Technical Circular 250.
9. Remove the flame tube and check the condition of the flame tube end. The flame tube should be light brown in colour with no excessive carbon at the end of the flame tube. Check for carbon build up on the burner “nose” at the cold end of the flame tube. Any carbon covering the air slots should be removed. Check the inside of the heat exchanger and scrape any loose carbon out from between the fins in the heat exchanger. Re‐install the flame tube replacing all gaskets.
10. Re‐assemble the heater and test operation. The heater should be bench tested for 15‐20 minutes before returning it to the vehicle.
11. Regardless of the season, run the heater every month for a minimum period of 15 minutes. This will help the heater burn away any combustion residue in the burner chamber and prevent corrosion in the waterjacket and decay of “O” rings.

AIRTRONIC Air Heaters
Eberspaecher’s air heaters are independent of both the engine and of the vehicle’s own heat balance. They draw in cool room or outside air, heat this up and then deliver it to the interior of the vehicle. Air heaters are an excellent solution for commercial vehicles of every type.
HYDRONIC Coolant Heaters
Eberspaecher’s coolant heaters work independently of the engine and thus offer a double plus: pre-heating the vehicle’s passenger compartment and the engine. The heaters are integrated into the cooling system of the engine. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air and this heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.

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.
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.”

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:
Proper 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.
1) Overheating of the compressor occurs. 
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.

Arctic Traveler Canada offers two different Cab Pressurizers or Cab Filtration 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 vapours 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.

The air is then filtered and blown into the air conditioner intake duct with our self contained air pump. All in a very small space. 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 which 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”.
