We replaced aging reciprocating compressors with Gardner Denver variable-speed screw units across our three cold storage distribution centers. The CompressorView diagnostics platform detected a bearing anomaly in one unit at our Memphis facility 11 days before it would have caused a shutdown — the system flagged a 0.3mm increase in vibration amplitude on the discharge side bearing. Over 14 months of operation, our metered energy data shows a 28% reduction in kWh per ton of refrigeration at matched capacity.

Technical FAQ

Common compressor selection, refrigerant compatibility, and service questions from our engineering inquiry data.

Compressor Selection

Our compressor platforms support R-290 (propane), R-744 (CO2 transcritical and subcritical), R-1234ze, R-134a, R-404A, R-410A, and R-407C. Each compressor datasheet specifies the approved refrigerant list and corresponding operating envelope. For R-290 and R-744 applications, dedicated compressor series with reinforced pressure ratings and ATEX-compliant motor housings are available.

The choice depends on capacity, evaporating temperature, and load profile. Screw compressors are preferred above 50 kW for continuous-duty applications with variable loads, as their VFD compatibility enables 30-50% part-load energy savings. Reciprocating compressors are typically specified for applications below 120 kW, especially in cascade systems or where multiple fixed-capacity stages are required. Our application engineers provide side-by-side comparison data for specific project conditions.

COP varies by compressor type, refrigerant, and operating conditions. Our screw compressors typically achieve COP of 4.0 to 5.8 at standard ARI conditions, while reciprocating units range from 3.2 to 4.5. All published COP data is AHRI-certified and verified through third-party testing. Full performance curves including IPLV data are available in each compressor series datasheet.

Service & Support

Yes. Our OEM engineering team provides system-level integration support including compressor selection matrices, vibration analysis, piping layout validation, and control interface documentation. We work with chiller, heat pump, and condensing unit manufacturers to ensure proper compressor-to-system matching. OEM partners receive dedicated engineering contacts and priority access to new product development information.

CompressorView is our integrated diagnostics platform that monitors vibration amplitude, discharge temperature, oil pressure, suction superheat, and motor current in real time. The system uses threshold-based alerts and trend analysis to predict maintenance needs before failures occur. Dashboard access is included with all new compressor units for 24 months, with extended subscriptions available.

Gardner Denver operates 22 service centers across 52 countries. For customers on our Preventive Maintenance Agreement, emergency response time is 24 hours in major metropolitan areas and 48 hours in regional locations. All service technicians carry genuine replacement parts for common wear items. Remote diagnostics through CompressorView can resolve approximately 35% of service calls without an on-site visit.
