Product features
Maximum versatility
RKY/RKYII is ideal choice for powering equipment such as construction machinery. Meticulous construction and premium quality components ensure trouble-free operation in ambient temperatures ranging from -20°C to +45°C. Versatility is further enhanced by the chassis, which can be equipped with a fixed or height adjustable tow bar and with or without an overrun brake. Stationary versions can be installed either on skids or machine mounts.
Lightweight
Powerful doesn't necessarily mean heavy: the RKY/RKYII is exceptionally easy to manoeuvre and transport. Moreover, its larger diesel fuel capacity ensures that the compressor has more than enough power available to last an entire work shift.
Separate air filters for engine and compressor
The air filters are specifically tailored to suit required air demand and therefore ensure dependable system operation. Afurther important design detail is the electric fuel pump, which enables quick and simple deaeration of the diesel lines, thereby eliminating the need for labour-intensive manual pumping.
Optional diesel engine
Flexible diesel engine to meet the different operating environment and conditions of operation, general maintenance, regard less of the location of the compressor, customers can find a suitable supplier of parts.
Simple to operate
Operation is made simple via user-friendly icons and a single start switch with pre-heat function. The unit also features fully automatic monitoring and shutdown in case of malfunction, whilst a pressure gauge and airend temperature display enable all information to be viewed at a glance.
Silent Environment
Silent case design, even in the noisy city can maintain a good noise level, to avoid noise caused by environmental pollution.
