Pain Point 1: Poor Oil Return Due to Oil-Refrigerant Incompatibility
The Problem:
Retrofitting R22 to R404A while using mineral oil causes poor miscibility with HFC refrigerants
Lubricant fails to return to compressor, leading to oil starvation
Results in dry friction, bearing failure, or cylinder scoring
The Solution:
160PZ features POE base oil that matches HFC refrigerant polarity
Forms uniform mixtures with R404A, R407C, and R134a
Ensures efficient oil circulation throughout the system
Eliminates oil return problems completely
Pain Point 2: Start-up Wear Under Low-Temperature Conditions
The Problem:
In cold storage applications, oil viscosity rises sharply after system shutdown
Conventional oil cannot reach friction surfaces quickly during restart
Creates "dry running periods" that accumulate over time
Leads to bushing wear, increased noise, and efficiency loss
The Solution:
160PZ features ultra-low pour point: -51°C to -54°C
Maintains excellent fluidity even at -40°C evaporation temperature
Establishes immediate oil film protection at start-up
Minimizes start-up wear significantly
Pain Point 3: Carbon Deposits from High-Temperature Oil Degradation
The Problem:
Compressor discharge temperatures often exceed 100°C
Conventional oils undergo thermal decomposition under high heat
Generates gum and carbon deposits
Blocks oil filters, capillaries, or expansion valves
Causes oil supply interruption or throttling failure
The Solution:
160PZ flash point exceeds 244°C
Exceptional thermal stability prevents molecular breakdown
Inhibits carbon formation effectively
Maintains clean oil circuits
Extends compressor maintenance cycles
Conclusion
✓ Solves poor oil return through POE-HFC compatibility
✓ Prevents low-temperature start-up wear with ultra-low pour point
✓ Eliminates high-temperature carbon deposits via superior thermal stability
