HERTZ Screw Compressors are designed to serve you trouble free, for long life time and each component is selected carefully in accordance with this purpose.
SIMPLE
With a simplified, easy to maintain structure and with long life components, a trouble-free operation is provided.
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 compressors performance, new CAD Methods and utilization of modern production technology
In our airends, the male rotor has four lobes and the female five lobes. This provides the shortest seal line and smallest inner leakage and provides more air volume capacity. The new rotor profile with minimized “blow hole” reduces torque requirement, which means low power consumption.
AIR INTAKE SYSTEM
Replaceable glassfibre panel type pre-filter and dry type paper filter element eleminate dusty ambient problem.
Air intake fan creates turbo effect inside of the machine. This effect provide efficient cooling and help the airend intake capacity. Piston controlled intake valve is chosen right size, which means high capacity and low power consumption.
AIR/ OIL SEPARATION
Effective design provides three stage separation.
Long life separator elements reduce oil in compressed air less than 3 ppm. Spin-on elements provides fast and easy separator element replacement.
THERMOSTATIC VALVE
4 ways thermostatic valve on multi-block provide trouble free operation in low ambient temperatures.
AIR / OIL AFTERCOOLER
Long life and trouble free operation with “bar/ plate” type aluminium combi-cooler. Coolers are selected to provide trouble free operations even in high ambient temperatures.
AIR TANK RECEIVERS
Designed according to CE regulations. Made of special P265 GH type pressure vessel steel.
Manual water drain valve.
Air discharge valve.
Powder coating paint.
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.
FLEXIBLE SYSTEM OPTIONS
Through the “modular system” that provides technically optimum solution, the opportunity to choose the system that best answers your needs. According to your requirements you can choose;
• Base compressor with sound proof canopy
• Tank mounted compressor with sound proof canopy
• Tank mounted compressor dryer and air filtration solution provided together as an exclusive problem free all in one system functioning even at 45°C ambient temperatures.
CONTROL PANEL AND CUBICLE
Electronic 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 chosen from well known brands all over the world.
VIBRATION PAD
Special rubber vibration pads eliminates vibration and problems it may cause.
