Sun Frozen Oil Packaging Upgrade

In the precision‑driven world of the refrigeration industry, refrigeration oil is often referred to as the “lifeblood” of compressors. As a long‑standing industry leader, Sun Oil Company’s SUNIiS0 GS series has, over the years, become synonymous with reliability in the eyes of refrigeration engineers, thanks to its exceptional stability and broad compatibility. Now, this iconic series is undergoing a significant brand refresh: SUNISOGS has officially been rebranded as SUNICEGS, with packaging updated to match.

It is worth noting that this change applies exclusively to the GS product line, while all other product lines under Sun Oil remain unchanged. This is a precisely targeted upgrade—both a tribute to the brand’s legacy and a strategic move for the future.

From ISO to iCE: A Single-Character Shift, an Upgrade in Connotation

For technicians familiar with Sun products, the “SUNISO” brand has been a trusted name for decades. While the change from SUNISO to SUNICE may seem like a simple one-word shift, it actually reflects the brand’s rethinking of its product positioning.
“SO” signifies that the product meets the specification standards of the International Organization for Standardization, while “CE” ingeniously embodies a dual meaning: on the one hand, it directly echoes the core application scenario of “refrigeration” (ice), and on the other, it also suggests the product’s optimized performance in areas such as low‑temperature fluidity and refrigerant compatibility.

Visual Refresh: Clearer, More Professional
Along with the brand name change, the SUNICEGS series has also undergone a comprehensive packaging upgrade. The new packaging adopts a more modern and professional design language:

Core recognition is more prominent. The product name “SUNICEGs” is displayed in a larger font, complemented by bold color‑coded sections, enabling technicians to quickly identify and retrieve it from tool cabinets or on the repair site.

The brand’s legacy endures. Although the name has changed, the new packaging retains Sun Oil’s classic brand colors and core visual elements, ensuring that longtime customers can instantly recognize the familiar promise of quality.

Unchanged quality: The Gs series’ core strengths remain intact.
It is particularly important to emphasize that this change… Limited to the brand name and packaging visuals. , The product formulation, performance specifications, and manufacturing process of SUNICE GS are entirely identical to those of the original SUNISO GS. This means:
Excellent chemical stability It does not react with refrigerants or compressor materials upon prolonged contact and does not generate harmful deposits.

Excellent low-temperature fluidity 1. Ensure smooth oil return to the compressor even under low-temperature conditions in the evaporator.
Reliable lubrication protection It forms a durable oil film under high-temperature, high-pressure operating conditions, effectively extending the compressor’s service life.
Wide refrigerant compatibility It is applicable to a variety of commonly used refrigerants, including R22, R744, R290, and R1233zd. For equipment manufacturers that have already incorporated SUNISo Gs into their product certification systems, no formulation adjustments or retesting are required; they can switch directly to using SUNICE GS.

Smooth Transition: Simply for a Clearer Product Positioning
Sun Oil’s decision to refresh the brand identity of only the GS series reflects a well‑thought‑out product strategy. As the “classic” and best‑selling line within Sun’s refrigeration oil portfolio, the GS series serves the broadest range of applications. By rebranding from the generic “SO” to the more industry‑specific “CE,” Sun Oil aims to send a clear message: the GS series remains the most professional and trusted choice in the refrigeration sector.
Meanwhile, the other product lines remain unchanged, ensuring the stability of the overall product portfolio. For customers who have long relied on Sun products, this “partial refresh” approach strikes a balance: it injects a sense of novelty while minimizing potential confusion that could arise from a full‑scale overhaul.

User Notice: Existing inventory may continue to be used.
In response to this change, Sunoco has also issued clear guidance to distributors and end users:
Both the new and old packaging are equally valid. On the market, both SUNISOGs products in the old packaging and SUNICEGS products in the new packaging will coexist, but they are equally effective.

Performance is completely identical. No need to adjust usage habits or system parameters due to packaging changes.

Simply transition naturally. We recommend that channel partners gradually sell off their existing packaging inventory to ensure a smooth transition to the new packaging.

From SUNISO GS to sUNICE GS, only the name and packaging have changed—what remains unchanged is the time-tested commitment to quality. For end users, when you pick up that can of sUNICE GS refrigeration oil, with its more modern design and clearer labeling, rest assured: you’re still holding the same trusted, classic formulation—the reliable “heart” that keeps your refrigeration system running smoothly.
This refresh is both a tribute to the past and an expression of hope for the future. The classic endures, simply donned in a new guise better suited to our times.
