OJ ElectronicsDedicated Compressor Drives

With a dedicated drive for scroll 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 DC series has a compact housing to fit your exact installation and match your compressor specifications.

FeaturesDesigned to Meet Your Requirements

As with all solutions from OJ Electronics, simplicity and efficiency are absolute keywords. The focus revolves around developing and delivering the functions and features you need and offering the best possible system to your customers.

The OJ DC series is developed according to the DV series standards, combining EC (electronic commutation) and FC (frequency converter) technologies.

System ReliabilityRobust and Built to Last

OJ DC 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.

Durability has been an essential keyword throughout the R&D phases, rendering DC 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.

The OJ DC series continuously operates in almost any environment from -40°C to +50°C / -40°F to +122°F. 

OJ Drives for Compressors

Cost-BenefitEnergy-Efficient

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

ComplianceIntegrated EMC Filter

Like the OJ DV series, the DC 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).
