Performance improvement: wear reduces over time – whereas in other compressor technologies wear increases as the compressor is used.
REVS is a pneumatic system that measures the internal pressure of the compressor and is automatically activated as soon as the compressor goes off-load. REVS uses solenoids to internally vent the compressed air down in the Air Ends RSU (Rotor, Stator Unit) to 2.0 bar (30 psi). There is an internal count down timer, dependent on model that can be adjusted:
Internally venting the compressed air means the compressor does not try to compress air already compressed, which results in energy consumption reducing to as low as 20%. Air is instantly available at anytime during this venting period (instant restart at any reducing pressure).
REVS also delivers low starting current by having the intake valve closed during start sequence. As the compressor starts with no internal pressure this means reduced motor power.
REVS only takes place when the compressor runs-on in an off-load condition.
The HV55 and HV75 horizontal enclosed compressor models have an earlier version of REVS known as Auto-idle. The Auto-idle system is a hydraulic system based on oil pressure and was also incorporated within our legacy horizontal models 18 kW to 45 kW (PSAS/PUAS).
The Hydrovane Advance 10 warranty is valid for up to 10 years or 48,000 operating hours* and is free to the compressor owner.
The compressors covered within the scope of the programme are between 4 kW to 75 kW (excluding gas compressors, HV04RM, HV05RM**, HV07RM** and non-standard products (NSPs), this includes a lifetime guarantee on the cast iron blades contained in the compression element, providing specified conditions are met.
