HVACCompressor Drives

With a dedicated drive for compressors in your chiller or AHU, you can rest assured that you will have optimal lubrication control and flawless performance regardless of variable loads or capacity. The series has a compact housing to fit your exact installation and match your compressor specifications.

To ensure safety and future-proof your systems, all OJ compressor drives are certified ignition protected in accordance with applicable UL and IEC standards.

The OJ compressor drives include Safe Torque Off (STO) to prevent unintended motor operation by disabling the drive output without requiring external contactors. Compliance with IEC 61800-5-2 and ISO 13849-1, STO enhances safety by ensuring a controlled shutdown of the compressor. This simplifies system design, reduces downtime, and ensures reliable operation in HVAC, AHUs, and chiller applications.

The OJ compressor drive series save energy while providing reliable, highly efficient power for the compressor. With OJ compressor drive, there will be an efficiency of up to 97%. Energy savings are the first step toward increasing sustainability in your business.  

Like the OJ ventilation drive series, the OJ compressor drive series comes with a fully integrated EMC filter and therefore meets the criteria for emissions and immunity in industrial and residential areas and complies with EN 61800-3 (C1 and C2).
