Eberspaecher, the leading system developer and supplier of vehicle heaters, is expanding its product portfolio with the new Hydronic heater, the S3 Economy (5kW) pre-heater. The water heater impresses thanks to its compact dimensions and flexible installation options for simple retrofitting in a large number of vehicle models. As a ground-breaking all-in-one solution with comprehensive peripheral devices, it offers installation partners many practical advantages. With the new EasyScan, diagnostic and service tool, workshop staff can analyze the operating condition of the pre-heater easily and quickly.
• Compact, efficient water heater • Innovative peripheral devices and new diagnostic device • Simplified installation • CARB approved
Compact and robust water heater for simple installation
With the third generation of its Hydronic heaters, Eberspaecher is offering an easy-to-operate preheater with stepless heating power control. The coolant or hydronic heater works efficiently with all popular types of fuel. Due to its robust construction – with an encapsulated fan motor and the separation of cold and hot components – it is designed for longevity. A high IP protection class also secures the unit from the ingress of water during high-pressure or steam jet cleaning. The new water spigots are fully rotatable by 360 degrees and are fully replaceable, they ensure convenient and rapid fitting in a range of installation positions. Optimized brackets enable the pre-heater to be mounted anywhere in the smallest possible space and to be attached rapidly and permanently.

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.”

Cabin Air Filters – Increase A/C efficiency and Reduce dust, dirt and allergensA 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.
