Sikelan QD35HG Compressor R134a Nairobi | Wisdo Merchants

Sikelan QD35HG Compressor for R134a Fridges and Small Coolers

When a fridge stops cooling and the compressor will not start, the quickest fix is often a direct replacement. The Sikelan QD35HG compressor gives repair shops a compact, affordable unit for small R134a appliances. At Wisdo Merchants, we supply it to appliance technicians, refrigeration repairers and service workshops across Nairobi and Kenya.

Sikelan makes hermetic compressors for household and light commercial refrigeration. The QD35HG is a small sealed unit built for R134a refrigerant and a standard 220–240 V household supply. As a result, it suits many fridges, small freezers, bottle coolers and water dispensers that originally ran on R134a.

Features and Benefits of the Sikelan QD35HG Compressor

• Built for R134a. It matches the many refrigerators and small coolers designed for R134a gas.
• Runs on household power. It works on a standard 220–240 V single-phase supply, so no special wiring is needed.
• Hermetically sealed. The motor and pump sit inside a welded shell, which keeps refrigerant in and moisture out.
• Compact size. It fits the tight compressor compartments of household fridges and small cabinets.
• Cost-effective repair. Replacing the compressor is often far cheaper than buying a new appliance.

For your customers, this means getting their fridge working again at a fair price. Meanwhile, your workshop gains a dependable replacement unit to keep in stock.

Technical Specifications

Applications of the Sikelan QD35HG Compressor and How to Use It

• Household refrigerators and fridge-freezers built for R134a
• Small chest and upright freezers
• Bottle coolers and small display chillers
• Water dispensers with cooling functions
• Like-for-like replacement of a failed small R134a compressor

Replacing a Fridge Compressor

Picture a household fridge whose compressor hums but will not start, even with a new relay. First, the technician confirms the compressor has failed and recovers any remaining gas. Next, they cut out the old compressor and fit the Sikelan QD35HG, together with a new start relay, overload protector and filter drier. After that, they braze the joints, pressure-test with nitrogen and pull a deep vacuum. Finally, they charge our HFC-134a by weight, matching the figure on the fridge’s rating plate.

Match the Gas and the Size

Always check the rating plate before choosing a replacement. The QD35HG is for R134a appliances only. Many newer fridges use R600a instead, and those need a compressor built for that gas along with our isobutane for modern fridges. In addition, match the compressor’s cooling capacity to the original. A unit that is too small will run constantly, while one that is too large can short-cycle.

Safety and Handling

• Use trained technicians. Only qualified refrigeration or appliance technicians should replace compressors.
• Isolate power before work. Unplug the appliance before touching any wiring.
• Keep the oil dry. POE oil absorbs moisture quickly, so keep the compressor ports sealed until fitting.
• Keep it upright. Store and transport the compressor upright so the oil stays in the sump.
• Purge with nitrogen while brazing. This prevents scale forming inside the pipes.
• Never run without refrigerant. Running a compressor in a vacuum can damage the motor.

Frequently Asked Questions

Can I use the QD35HG in an R600a fridge?

No. It is built for R134a. R600a appliances need a compressor designed for that gas.

Should I replace the relay and overload too?

Yes. Fitting a new start relay and overload protector with the compressor helps prevent repeat failures.

Why did my old compressor fail?

Common causes include voltage surges, refrigerant leaks, moisture in the system and blocked capillary tubes. Fixing the root cause protects the new compressor.

Do I need to change the filter drier?

Yes. Always fit a new filter drier whenever you open the system or replace the compressor.
