Oljekontroll, R134a

The NUNCHI CLIMATE OIL CHECKER R134a is a professional diagnostic tool designed to give technicians a visual indication of the oil and contamination condition inside an R134a automotive A/C system.

Instead of relying only on pressure and temperature measurements, the Oil Checker allows the technician to visually inspect material passing through the transparent inspection chamber.

This provides valuable additional information when diagnosing A/C problems, evaluating compressor-oil condition and deciding whether further service, repair or A/C system flushing may be required.

SPECIFICALLY FOR R134a A/C SYSTEMS

The NUNCHI CLIMATE OIL CHECKER R134a is configured for use with automotive A/C systems using R134a refrigerant.

This makes it an ideal diagnostic companion for workshops servicing the large number of R134a vehicles still operating worldwide.

R134a SYSTEM? CHECK WHAT IS HAPPENING INSIDE.

The Oil Checker adds a visual diagnostic step to the normal A/C service process:

• Connect → Inspect → Evaluate → Diagnose → Service

SEE THE CONDITION – DON'T JUST GUESS

Pressure and temperature readings provide important information about how an A/C system is operating.

But they do not necessarily show the technician what is circulating inside the refrigerant circuit.

The NUNCHI CLIMATE OIL CHECKER R134a provides a visual window into the system.

The transparent inspection chamber can help the technician look for indications of:

• Compressor-oil condition
• Oil discoloration
• Excessive oil
• Contaminated oil
• Suspended contamination
• Visible particles
• Abnormal residues
• Possible internal compressor wear

MAKE THE INVISIBLE VISIBLE.

The Oil Checker gives the technician additional diagnostic information before important service and repair decisions are made.

CHECK THE COMPRESSOR-OIL CONDITION

Compressor oil is critical to the reliability of an R134a A/C system.

The oil lubricates and protects the compressor while circulating through the refrigerant circuit.

• Over time, the oil can be affected by:
• Heat
• Moisture
• Wear
• Contamination
• Incorrect Oil
• Compressor Damage

The Oil Checker R134a allows the technician to visually evaluate the condition of material circulating through the system.

CLEAN OIL

Can support an assessment that the system has good internal cleanliness.

DARK OR DISCOLORED OIL

May indicate ageing, overheating or contamination that should be investigated further.

VISIBLE PARTICLES

Can indicate internal wear or component damage and should trigger additional diagnosis.

EXCESSIVE OIL

May indicate incorrect previous servicing and can contribute to reduced A/C performance.

AN IMPORTANT TOOL BEFORE FLUSHING

One of the most valuable applications for the NUNCHI CLIMATE OIL CHECKER R134a is helping determine whether further system investigation or flushing may be required.

Instead of automatically flushing every vehicle, the technician can inspect the condition of the system and make a more informed service decision.

CHECK → INSPECT → DECIDE → FLUSH IF REQUIRED

If abnormal oil or contamination is identified, the technician can determine whether:

• The A/C system requires flushing
• Compressor oil should be replaced
• A component requires replacement
• Additional diagnosis is necessary
• The system should be cleaned before installing a new component

IDEAL BEFORE COMPRESSOR REPLACEMENT

Compressor replacement is one of the most important situations where internal system condition should be evaluated.

If an R134a compressor has suffered internal mechanical damage, contamination can potentially circulate through other parts of the A/C system.

Installing a new compressor without investigating the remaining system can expose the replacement component to existing contamination.

DON'T JUST REPLACE THE COMPRESSOR – CHECK THE SYSTEM.

• Before replacement, consider:
• Why did the compressor fail?
• What condition is the compressor oil in?
• Is visible contamination present?
• Does the system require flushing?
• Could other components be contaminated?

The Oil Checker R134a provides an additional visual diagnostic tool to help answer these questions.

USE BEFORE & AFTER FLUSHING

The Oil Checker can also be used as part of a professional A/C flushing procedure.

BEFORE FLUSHING

Inspect the oil and look for visible contamination.

• ↓

FLUSH THE SYSTEM

Perform the appropriate flushing procedure.

• ↓

CHECK AGAIN

Use the Oil Checker as part of evaluating system cleanliness following the flushing procedure.

• This creates a professional approach:

INSPECT → FLUSH → VERIFY

Instead of assuming that completion of a flushing cycle automatically means the system is clean, the technician has an additional way to evaluate the result.

THE PERFECT PARTNER FOR AN A/C MACHINE WITH FLUSHING

The NUNCHI CLIMATE OIL CHECKER R134a is particularly valuable when combined with an A/C service machine equipped with an integrated flushing function.

• Evaluate the result

Together, these tools create a more comprehensive A/C service process:

• CHECK
• FLUSH
• VERIFY

HELP IDENTIFY CONTAMINATION EARLY

Identifying contamination before a major component failure can help technicians make better repair decisions.

The Oil Checker R134a provides another method of identifying warning signs inside the refrigerant circuit.

• Early detection can help reduce the risk of:
• Repeat compressor failure
• Installing new components into a contaminated system
• Incomplete repairs
• Incorrect oil diagnosis
• Unnecessary component replacement
• Customer comebacks

SIMPLE VISUAL DIAGNOSIS

One of the biggest advantages of the NUNCHI CLIMATE OIL CHECKER R134a is its simplicity.

The transparent inspection chamber gives the technician an immediate visual reference.

SEE IT. EVALUATE IT. MAKE THE SERVICE DECISION.

• This makes the Oil Checker useful for:
• Professional A/C Technicians
• Independent Workshops
• Dealerships
• A/C Specialists
• Training Centers

It can also be an excellent training tool for demonstrating the importance of compressor oil and internal system cleanliness.

SHOW THE CUSTOMER

Visual diagnosis can also help technicians explain A/C problems to customers.

• Instead of simply telling the customer:
• "We found contamination in your A/C system."

the technician can use visible findings from the inspection process to help explain why additional work may be recommended.

• This can make it easier to explain services such as:
• A/C system flushing
• Compressor-oil replacement
• Compressor replacement
• Receiver drier replacement
• Additional system cleaning
• Further diagnosis

SEEING THE PROBLEM MAKES THE REPAIR EASIER TO EXPLAIN.
