7HP Copeland Compressor R134a 3 Phase | Wisdo Merchants

Description

7HP Copeland Compressor for Cold Rooms and Commercial Chillers

When a cold room compressor fails, every hour of downtime puts stock at risk. Replacing it with a reliable, correctly sized unit gets the system back to temperature fast and keeps it there. At Wisdo Merchants, we supply the 7HP Copeland compressor for R134a systems to refrigeration contractors, technicians and plant owners across Nairobi and Kenya.

Copeland is one of the world’s best-known compressor brands, trusted in commercial refrigeration and air conditioning for decades. This model is built for R134a refrigerant and runs on a three-phase power supply. As a result, it suits medium-temperature commercial systems where steady, efficient cooling matters most.

Features and Benefits of the 7HP Copeland Compressor

• Matched to R134a. It is designed for R134a, a reliable gas for medium- and high-temperature refrigeration.
• Three-phase power. Three-phase electric power gives smoother running and lower current per line than single-phase motors of the same size.
• Commercial-duty capacity. A 7HP rating suits mid-sized cold rooms, chillers and process cooling systems.
• Proven brand reliability. Copeland compressors have a long track record in commercial refrigeration worldwide.
• Easy servicing. Because Copeland is widely used, technicians are familiar with its installation, wiring and maintenance.

For plant owners, this means dependable cooling and less downtime. Likewise, contractors get a compressor they can install and service with confidence.

Technical Specifications

Applications of the 7HP Copeland Compressor and How to Use It

• Chiller cold rooms for fruit, vegetables, dairy and drinks (above-freezing storage)
• Supermarket multi-deck chillers and display cabinets
• Water and process chillers in factories and hotels
• Milk cooling and beverage cooling systems
• Replacing a failed R134a compressor of the same capacity

Replacing a Failed Compressor

Picture a dairy cold room whose old compressor has burnt out. First, the technician recovers the refrigerant and finds the cause of the failure, such as phase loss, overheating or poor oil return. Next, they remove the old unit and flush or clean the system if the oil shows signs of burnout. After that, they install the new Copeland compressor, fit a new filter drier and connect the three-phase supply through the correct contactor and overload protection. Finally, they pull a deep vacuum, charge our HFC-134a by weight and check running current and pressures.

Protect Your Investment

Unstable power is a common cause of compressor failure in Kenya. Therefore, fit a phase-failure relay to stop the compressor if one phase drops or the voltage falls too low. In addition, check the phase sequence during installation, because some compressor types are damaged if they run backwards. Learn more about how these systems work in this guide to vapour-compression refrigeration.

Safety and Handling

• Use qualified installers. A trained refrigeration technician and a licensed electrician should install and wire the compressor.
• Match the power supply. Confirm that the voltage and frequency on the nameplate match your three-phase supply before connecting.
• Isolate power before work. Always switch off and lock out the supply before touching terminals or wiring.
• Keep the oil dry. POE oil absorbs moisture quickly, so keep the compressor sealed until installation.
• Handle with care. Lift the compressor using proper equipment, and keep it upright during transport and storage.
• Never run without refrigerant. Running a compressor in a vacuum can damage the motor windings.

Frequently Asked Questions

Can I use this compressor with R404A or R22?

No. This model is designed for R134a. Using a different refrigerant can overload the motor or reduce cooling capacity, so always match the compressor to the system’s gas.

What size cold room does a 7HP compressor suit?

That depends on the room’s size, insulation, door use, product load and target temperature. A refrigeration engineer should calculate the cooling load before you choose a compressor.

Does it come with oil?

Yes. Copeland compressors are supplied with a factory oil charge. Check the level after installation and top up only with the oil type shown on the nameplate.

Why did my last compressor fail?

Common causes include phase loss, low voltage, refrigerant leaks, moisture in the system and poor oil return. Fixing the root cause protects your new compressor.
