Bock Refrigeration Compressors Buyer's Guide

Pre-Order Inquiry
Pre-Order Inquiry: The "Identity First" Guide

The Nameplate is Key: The model number alone is sometimes insufficient. We request a clear photo of the manufacturer’s metal nameplate. This confirms the specific Series, Voltage, and Bill of Material (BOM) number.

Refrigerant Verification: You must confirm the gas type (e.g., R134a, R404A, R290, or R410A). Using the wrong refrigerant in a Bock compressor designed for a different gas will lead to immediate failure and void the warranty.

Voltage & Frequency Check: Global power grids vary. Whether you need 115V/60Hz (USA), 220V/50Hz (Europe/Asia), or 3-Phase 380V, this must be explicitly confirmed during the inquiry stage to prevent electrical burnout.

Eliminate compatibility errors before the order is placed. To ensure you receive the exact compressor needed for your HVAC or refrigeration system, we adhere to a strict "Identity First" protocol.
Parameter Matching Testing Reports
Technical Validation: Parameter Matching & Testing Reports

Application Matching: We verify if your application requires LBP (Low Back Pressure for freezers), MBP (Medium), or HBP (High Back Pressure for A/C and chillers). Installing an LBP compressor in an HBP application will cause the motor to overheat.

Performance Benchmarking: Before shipment, units undergo rigorous testing for volumetric efficiency, motor amperage draw, and noise levels

The Test Report: For peace of mind, we can provide a Quality Inspection Report or a video of the Bock compressor under load test, proving it holds pressure and operates within factory specifications before it leaves our facility.

Prove performance and reliability through data. Once the model is identified, we focus on technical validation and quality control.
Supply Strategy: Inventory Matching, Batch Production
Supply Strategy: Inventory Matching & Batch Production

Spot Buy (Ready Stock): For urgent repairs, we leverage our global inventory of popular brands (Tecumseh, Copeland, Danfoss) to offer "2nd-Day Dispatch" on common Bock models.

Batch Production (OEM Orders): For distributors or appliance manufacturers requiring 50+ units, we schedule a production run. This typically requires a 2-4 week lead time but offers significant cost savings.

Condition Clarity: We clearly distinguish between "Factory New" (fresh production) and "New Surplus" (older stock). We allow you to choose based on your budget and warranty requirements.

Optimize lead times based on your urgency and volume. We offer flexible solutions depending on whether you are replacing a single unit or stocking up for manufacturing.
Global Shipping
Logistics & Distribution: Global Shipping

Robust Crating: We do not use standard cardboard for international freight. All compressors are bolted to a pallet and sealed in fumigated wooden crates compliant with ISPM 15 standards for global entry.

Upright Transport: Compressors must remain upright to prevent oil from entering the compression chamber (which causes "liquid slugging"). Our packaging includes "This Side Up" shock sensors and indicators.

Customs & Documentation: We handle the complex paperwork, including Commercial Invoices and Certificates of Origin, ensuring your goods clear customs smoothly whether shipping via DHL Air Express or Sea Freight to any port in the world.

Ensure the heavy, precision equipment arrives undamaged. Bock compressors are heavy, oil-filled components that require specialized handling for international transport.
