For GHH RAND oil-injected airends we developed this series of high performance coolants. For contact cooled airends this lubricant provides cooling in the compression chamber and lubrication of gears and bearings.
A mineral coolant containing highly refined base oils and additives with an approved operating life of up to 4.000 running hours.
A synthetic coolant based on polyalfaolefine, offering an extended life cycle, with an approved operationg life of up to 8.000 running hours.
An additional and valuable benefit of using the GHH RAND family of PRIMECOOL® & PRIMECOOL® PLUS lubricants is an increased warranty period from 12 months up to 24 months for PRIMECOOL® use (limited to 12.000 running hours) and to 36 months for PRIMECOOL® PLUS with unlimited operating hours.
