System Reliability<\/small>Robust and Built to Last<\/h2>\n
\n
<\/div>\n

OJ compressor drive is built on proven OJ technology used in the existing DV series. The drives come in two compact housing sizes and have a power range span from 4kW to 15kW, depending on your needs and system requirements.<\/p>\n

Durability has been an essential keyword throughout the R&D phases, rendering OJ compressor drive ideal for central and decentralised locations where environments get rough. The new drives have high ingress protection and NEMA rating of IP54\/IP65 and NEMA 4X, respectively.<\/p>\n

The OJ compressor drive series continuously operates in almost any environment from -40\u00b0C to +50\u00b0C \/ -40\u00b0F to +122\u00b0F.\u00a0<\/p>\n<\/div><\/div>\n<\/p><\/div>\n

Propane Ready<\/small>Ignition Protected<\/h2>\n
\n

To ensure safety and future-proof your systems, all OJ compressor drives are certified ignition protected in accordance with applicable UL and IEC standards.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

Safe Torque Off (STO)<\/small>Integrated Safety<\/h2>\n
\n

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.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n
