Nunchi Climate for R513A

The NUNCHI CLIMATE BUSS R513A is a professional recovery, recycling, vacuum and charging station designed for servicing larger A/C systems using R513A refrigerant.

With its focus on high-capacity refrigerant handling, the BUSS R513A is an ideal solution for workshops servicing buses, coaches and other compatible large-capacity A/C systems, where refrigerant charges can be significantly larger than those normally found in passenger cars.

Designed for professional and demanding applications, the NUNCHI CLIMATE BUSS R513A combines efficient refrigerant recovery, recycling, vacuum and controlled charging in one robust workshop solution.

• HIGH CAPACITY • PROFESSIONAL SERVICE • R513A
• DESIGNED FOR R513A

The NUNCHI CLIMATE BUSS R513A is configured specifically for systems operating with R513A refrigerant.

R513A is a lower-GWP refrigerant blend used as an alternative to R134a in suitable applications. Using dedicated R513A service equipment helps maintain refrigerant integrity and reduces the risk of cross-contamination with other refrigerants.

DEDICATED EQUIPMENT FOR PROFESSIONAL R513A SERVICE.

BUILT FOR BUS & COACH A/C SYSTEMS

Bus and coach A/C systems present a very different service challenge compared with passenger cars.

A large passenger compartment requires significantly greater cooling capacity, which can mean:

• Larger refrigerant charges
• Longer refrigerant lines
• Larger condensers
• Larger evaporators
• Multiple evaporators
• Multiple fans
• Greater internal system volume
• Longer recovery and evacuation requirements

The NUNCHI CLIMATE BUSS R513A is designed to provide the professional refrigerant-handling capability required for these demanding applications.

BIGGER SYSTEMS REQUIRE BIGGER SERVICE CAPABILITY.

COMPLETE R513A SERVICE IN ONE MACHINE

The BUSS R513A brings the essential refrigerant-service functions together in one professional platform.

RECOVERY

Remove R513A refrigerant from the system in a controlled process.

↓

RECYCLING

Process recovered refrigerant through the machine’s recycling system.

↓

VACUUM

Evacuate the refrigerant circuit after recovery or repair.

↓

OIL MANAGEMENT

Support correct handling of compressor oil during the service process.

↓

CHARGING

Introduce the specified quantity of R513A into the system.

↓

VERIFY

Check system operation and performance after service.

• RECOVER → RECYCLE → VACUUM → CHARGE → VERIFY
• HIGH-CAPACITY REFRIGERANT RECOVERY

Large bus and coach A/C systems can contain several kilograms of refrigerant.

Efficient recovery therefore becomes an important part of workshop productivity.

The NUNCHI CLIMATE BUSS R513A provides professional refrigerant recovery before:

• Routine A/C service
• System diagnosis
• Leak repair
• Compressor replacement
• Condenser replacement
• Evaporator replacement
• Refrigerant-line repair
• Major system repair

Controlled recovery helps minimize unnecessary refrigerant loss while preparing the system for professional service.

PROFESSIONAL REFRIGERANT RECYCLING

Recovered refrigerant can contain oil and material originating from the A/C system.

The BUSS R513A incorporates refrigerant recycling into the service process, allowing recovered refrigerant to be processed according to the machine’s intended operating procedure.

RECOVER IT. PROCESS IT. MANAGE IT PROFESSIONALLY.

For workshops servicing systems with large refrigerant charges, professional refrigerant management can provide significant operational benefits.

DEEP VACUUM FOR LARGE SYSTEMS

Correct evacuation is critical after refrigerant recovery or when the A/C system has been opened for repair.

Vacuum helps remove:

AIR • MOISTURE • NON-CONDENSABLE GASES

These can negatively affect:

• Cooling performance
• Operating pressures
• Compressor oil
• Component reliability
• System efficiency

This is particularly important in bus and coach systems where long refrigerant lines and large heat exchangers create a significantly greater internal volume.

LARGE SYSTEM. LONG LINES. PROFESSIONAL VACUUM.

ACCURATE R513A CHARGING

Correct refrigerant quantity is essential for optimum A/C performance.

Too little R513A can result in:

• Reduced cooling capacity
• Incorrect operating pressures
• Poor refrigerant circulation
• Reduced system performance

Too much refrigerant can contribute to:

• Excessive high-side pressure
• Increased system load
• Reduced efficiency
• Poor cooling performance

The NUNCHI CLIMATE BUSS R513A provides controlled refrigerant charging, allowing the technician to introduce the specified R513A quantity according to the system manufacturer’s requirements.

CORRECT REFRIGERANT. CORRECT QUANTITY. CORRECT SERVICE.

DESIGNED FOR HIGH REFRIGERANT QUANTITIES

A conventional passenger-car A/C service station is designed primarily around relatively small refrigerant charges.

A bus or coach may require a very different level of refrigerant handling.

The BUSS R513A is designed with these larger applications in mind.

PASSENGER CAR

Smaller Refrigerant Charge

Shorter Refrigerant Lines

Smaller Heat Exchangers

versus

BUS / COACH

Larger Refrigerant Charge

Long Refrigerant Lines

Large Condensers

Large or Multiple Evaporators

Greater System Volume

The result is a machine designed for workshops where capacity and efficiency matter.

IDEAL FOR COMPONENT REPLACEMENT

The NUNCHI CLIMATE BUSS R513A is also an important workshop tool when the refrigerant circuit must be opened for repair.

This can include replacement of:

• Compressors
• Condensers
• Evaporators
• Expansion valves
• Receiver driers
• Refrigerant hoses
• Refrigerant pipes
• Pressure switches
• Sensors
• Other refrigerant-circuit components

The professional repair workflow becomes:

• RECOVER → REPAIR → VACUUM → CHARGE → VERIFY
• REDUCE REFRIGERANT LOSS

With large A/C systems, refrigerant management becomes especially important.

A bus or coach can contain considerably more refrigerant than a passenger vehicle. Even a relatively small percentage of unnecessary refrigerant loss can therefore represent a significant quantity.

Professional recovery helps:

Reduce Refrigerant Waste

Control Workshop Costs

Improve Refrigerant Management

Support Environmentally Responsible Service

RECOVER MORE. WASTE LESS.

IMPROVE WORKSHOP PRODUCTIVITY

Large A/C systems can take considerably longer to service than passenger-car systems.

Using equipment intended for high-capacity applications helps workshops manage these services more efficiently.

The NUNCHI CLIMATE BUSS R513A is designed to support:

• Efficient refrigerant handling
• Controlled service procedures
• Reduced manual intervention
• Consistent servicing
• Better technician productivity
• Professional management of larger refrigerant quantities
• LESS TIME WAITING. MORE TIME SERVICING.

DEDICATED R513A EQUIPMENT

Refrigerant cross-contamination can create expensive workshop problems.

Using a dedicated NUNCHI CLIMATE BUSS R513A service station helps maintain separation between R513A and other refrigerants.
