Features and Benefits

Cooling System – The Variable Speed Drive (VSD) series has been developed and sized to work at a 100% duty cycle even in the most severe conditions. Energy savings are achieved due to an inverter controlled fan of the oil cooler. All the components are fully enclosed and protected from contamination. The air cooling system has been sized to work at up to 125° F ambient temperature.

Industry 4.0 Capable – RKHD Compressors are Industry 4.0-Ready. The compressor can be networked locally and managed remotely via the internet.

Electronic Controller – The intuitive KTronic 1000 touch screen panel permits full access to the functions, parameter control and diagnostics of the unit, increasing the efficiency of the compressor.

Improved Air/Oil Temperature Control – The air and oil coolers are separate and managed individually on the RKHD-VSD Series. The oil cooler fan is inverter controlled and dynamically manages the temperature of the oil. The perfectly controlled oil temperature is a benefit to the oil circuit and further improves energy savings. In addition, the separate air cooler management allows optimization of the air temperature at the compressor outlet, avoiding condensation and eliminating the damages caused by moisture. As a result, the dryer after the compressor also benefits from the lower operating load.

Easy Maintenance – The access panels are easily removed and permit quick access to all the components that require routine maintenance. The air-oil separator cartridge can be quickly replaced with an easy rotation of the tank lid on its pivot arm.
