SpareX Company — supplier of BITZER spare parts

German quality for refrigeration and climate systems

BITZER is the largest independent manufacturer of refrigeration compressors with over 80 years of history. Headquartered in Sindelfingen, Germany. The company produces reciprocating, screw, and scroll compressors, heat exchangers, receivers, and electronic components for commercial refrigeration, industrial cooling, air conditioning, and heat pumps.

Sanctions barriers and complicated logistics from the EU create a real risk for enterprises operating BITZER equipment. A shutdown of a refrigeration line or chiller due to a missing spare part means direct losses: production downtime, spoiled products, and failure to meet customer commitments. SpareX arranges the supply of genuine BITZER components to Russia through verified logistics channels. We handle customs clearance and preparation of supporting documentation — you don't need to deal with import procedures. Stock items: 10–18 business days, made-to-order items: 25–45 business days.

Maintenance of BITZER equipment

Timely replacement of wear components — valve plates, shaft seals, bearings, oil filters — prevents emergency compressor shutdowns. Scheduled maintenance extends equipment service life and reduces costs for unscheduled repairs. SpareX ensures availability of consumables and repair kits for the entire BITZER product line.
