Choosing a replacement compressor for a commercial cooler can be stressful. You need to match the refrigerant, voltage, capacity, and mounting style, or you risk a failed repair and more downtime. The Secop SC15G provides a clear answer for many True and beverage-air setups, and it arrives as a complete kit with the electrical components you will likely need.
Quick Verdict
The SC15G is a 1/2 HP hermetic reciprocating compressor built for R134a, a common refrigerant in reach-in coolers and beverage machines. It is rated at 5606 BTU per hour at HBP conditions (+45°F), and it runs on 115-127V/60Hz power. For anyone replacing a True 842509 or a compatible compressor in a similar commercial unit, this Secop model offers the horsepower, BTU range, and voltage in a single box.
Who It Suits
This compressor suits technicians and shop owners who need a dependable replacement for a medium-temperature commercial refrigerator. The listed replacement references include True 842509 and 918731, Dixie Narco CR0005298, and Beverage Air 312-083D, so it targets equipment common in convenience stores, restaurants, and vending operations. If your system uses R134a and runs on standard 115V power, the SC15G is a strong candidate.
What Stands Out From the Listed Details
The SC15G is not just a bare compressor. It comes with a starting relay, overload protector, start capacitor (240 uF), grommets, cord relief, and an electrical cover. That makes the replacement process more straightforward because you are not hunting for separate components. The compressor height is listed at 8.23 inches, which gives you a useful dimension to compare against your existing unit before ordering.
Secop describes this as a compact hermetic reciprocating compressor with efficient motors and low energy consumption, building on over 50 years of manufacturing experience. That background is reassuring when you are trusting a component to run for years inside a sealed refrigeration loop.
Meaningful Trade-Offs
This is a 1/2 HP compressor with a 5606 BTU rating at high back pressure. If your cooler requires a different capacity, or if it runs on R404A or another refrigerant, this model will not be the right fit. The price is listed at USD 310.45, which reflects the included electrical components and the specific commercial-grade application. You should confirm your system's BTU requirements and refrigerant type before purchasing.
Another point to consider is that the SC15G is intended for HBP (high back pressure) systems. Low and medium temperature freezers usually demand different compressors, so this is a dedicated replacement for chillers and beverage coolers rather than a universal solution.
SC15G R134a Refrigeration Compressor 1/2 HP 5606 BTU HBP 115V for True 842509
Priced at USD 310.45, this compressor includes the relay, overload, start capacitor, grommets, cord relief, and electrical cover in the package. The listed height of 8.23 inches and the replacement cross-reference list make it easier to check compatibility. The main limitation is that it is a 1/2 HP HBP unit, so it will not serve low-temperature freezer applications.
Bottom Line
The Secop SC15G is a practical choice for a commercial cooler compressor replacement when you need R134a, 115V, and 1/2 HP. The included electrical parts, the compact design, and the clear replacement reference to True 842509 make it a straightforward option for a repair job. Just verify your existing compressor's BTU rating and refrigerant before committing to this model.
