Compressors for Refrigerators and Freezers

The compressor in a refrigeration unit performs the main function — it compresses the refrigerant, increasing its pressure and temperature so that the cooling cycle can once again absorb heat from the interior of the unit. A faulty or worn compressor does not provide sufficient pressure, causes increased energy consumption and cannot maintain the required temperature. Replacing the compressor is a cheaper alternative to replacing the entire refrigeration unit. BHS offers compressors for professional refrigeration equipment for HoReCa businesses across Europe.

Types of compressors and their applications

Hermetic compressors — the most common type for lighter commercial refrigeration equipment, refrigerators and beverage coolers. Hermetically sealed compressors are low-maintenance and highly reliable models with an integrated motor. Semi-hermetic compressors — for high-power equipment, freezer chambers and industrial systems where the motor and compressor parts can be replaced separately. Open-type compressors — for industrial and high-power systems with an external motor, suitable for high-capacity storage chambers. Each of these types has an important parameter — the refrigerant type (R134a, R290, R404A etc.), which must be taken into account when choosing a replacement compressor. BHS helps identify the right compressor.

Equipment that requires compressors

In professional refrigerators — under-counter, freestanding, built-in — the compressor is the main component of the cooling system, determining the operation of the entire unit. In freezer chests and freezer chambers, compressors must be replaced in a timely manner, as lower temperatures mean more intensive load. In refrigerated display cases in patisseries and restaurant bars, the compressor ensures that products are displayed at the ideal temperature. In beverage coolers and ice machines, the compressor is critical for ensuring product quality. In refrigerated display cases with strong sunlight exposure or in a hot kitchen environment, the compressor operates under increased load and wears out faster. BHS offers compressors for all these types of equipment.

HACCP and temperature control

In a refrigeration unit with a faulty compressor, the temperature may rise above +4°C, which is the food storage safety limit and a serious HACCP violation. In a freezer, a temperature rise above -12°C creates a risk of partial thawing and refreezing of products, which is both a safety and quality issue. Regular inspection of refrigeration equipment — temperature monitoring, analysis of compressor operating sounds and energy consumption control — is recommended as part of the HACCP maintenance schedule. Documenting the temperature log and timely replacement of the compressor are mandatory elements of food safety management. BHS helps choose the right compressor and ensures fast delivery.

HoReCa usage scenarios

A compressor failure in a restaurant’s main refrigerator overnight can mean the loss of all fresh products by the next morning — the losses far exceed the cost of replacing the compressor. In a patisserie, a compressor failure in a refrigerated display case during summer heat can spoil all finished products within a few hours. In a bar, a compressor failure in an ice machine will halt ice production, affecting beverage service. In a hotel’s large freezer chambers, compressor malfunctions require immediate action to avoid major product losses.

Frequently asked questions

How to determine if a compressor is faulty? Main signs: the unit does not maintain the required temperature, the compressor runs continuously without switching off, unusual noise or knocking from the compressor area, increased energy consumption. Diagnosis with manometers allows checking the system pressure — too low pressure indicates compressor wear or refrigerant leakage.

Can a compressor be replaced with a compatible model? Yes, compatible compressors with matching parameters — power (HP/kW), refrigerant type, connection dimensions and voltage — fully replace the originals. It is important to ensure that the refrigerant type matches the one used in the existing system. BHS helps choose the right compatible compressor.
