Hertz Screw Compressors are designed to serve you trouble free, long life time and each component is selected carefully in accordance with this purpose.
AIREND
High efficiency airends manufactured by one of the leading airend manufacturer in the world. Our airend design is based on new rotor profile and lobe combination, which is the result of long experience of screw compressor performance, new CAD Methods and utilization of modern production technology
The new rotor profile with minimized “blow hole” reduces torque requirement, which means lower power consumption.
AIR INTAKE SYSTEM
Two-stage air filtration system to provide clean for airend and cooling system and to eliminate problems in dusty environments. New range of intake regulators has been developed by using sophisticated software as well as FEM (finite element analysis) and fluid-dynamics to create low-pressure drop.
AIR/ OIL SEPARATION
Effective design provides three stage separation.
Long life separator elements reduce oil in compressed air less than 3 ppm.
THERMOSTATIC VALVE
4 ways thermostatic valve on multi-block provide trouble free operation in low ambient temperature.
COOLING SYSTEM
High performance and efficient cooling system to ensure the compressor to run at optimum temperature continuously.
Long life trouble free operation with “bar/plate” type aluminium combi-cooler. Cooler size is selected to provide trouble free operations even in high ambient temperatures.
Silent and efficient axial fans with new blade profiles.
Water-cooling option with “bar/plate” type copper heat-exchengers. New fan-housing designs to service and clean coolers easily.
DRIVING SYSTEM
Belts are selected according to 25.000 operating hours. Pulleys with taper bush can be easily disassembled and assembled. Easy belt tensioning system provide trouble free operation.
CONTROL PANEL AND CUBICLE
Electronic LCD panel indicates any type of operational and service activites in the easiest way to make everybody understand perfectly. Different type safety systems provides protection for any type of risk.
All electrical components in the cubicle are choosen from well known brand name all over the world.
VIBRATION PAD
Special rubber vibration pads eliminates vibration and problems it may cause.
