Why Use a Charging Scale?

Accurate refrigerant charging is critical for system performance and efficiency. Overcharging or undercharging can result in poor cooling performance, increased energy consumption, and potential damage to the compressor. A charging scale ensures you add precisely the right amount of refrigerant specified by the manufacturer.

R600a and R290 Refrigerants:

R600a (Isobutane):

• Natural refrigerant with low GWP (Global Warming Potential)
• Commonly used in domestic refrigerators and freezers
• Highly efficient with excellent thermodynamic properties
• Flammable - requires careful handling
• Small charge quantities (typically 30-150g)

R290 (Propane):

• Natural refrigerant with very low GWP
• Used in commercial refrigeration and heat pumps
• Excellent energy efficiency
• Flammable - requires safety precautions
• Larger charge quantities than R600a

How to Use:

1. Place scale on a stable, level surface
2. Connect R600a or R290 bottle to scale using 7/16" UNF connection
3. Turn on scale and allow it to stabilise
4. Press tare button to zero out the bottle weight
5. Connect charging hose to the bottle
6. Monitor weight as refrigerant is added to system
7. Stop charging when the correct weight has been dispensed
8. Record final charge weight for service records

Safety Considerations for Flammable Refrigerants:

• Ventilation – Ensure adequate ventilation when working with R600a/R290
• No Ignition Sources – Keep away from sparks, flames, and hot surfaces
• Leak Detection – Use electronic leak detectors rated for flammable refrigerants
• Proper Training – Ensure technicians are trained in flammable refrigerant handling
• Charge Limits – Never exceed manufacturer's specified charge quantities

Benefits:

• Precise Charging – 1g resolution ensures accurate refrigerant quantities
• Cost Savings – Avoid overcharging and wasting expensive refrigerant
• System Performance – Correct charge ensures optimal cooling efficiency
• Professional Service – Demonstrates precision and care to customers
• Compliance – Meet manufacturer specifications and regulations

Maintenance:

• Keep scale clean and free from refrigerant oil
• Store in a protective case when not in use
• Replace batteries when low battery indicator appears
• Calibrate periodically for accuracy
• Avoid dropping or impact damage
• Keep away from moisture and extreme temperatures
