High Performance VSD Screw Compressor For Dental Laboratories / Sand Blasting
Application
1. High efficiency motor:Using the latest standard motor with new national energy efficiency motors ,using imported SKF bearings.
1. Large starting torque
2. Insulation class F,IE3 protection class IP55
3. SKF bearing,low noise,long service life
4. With the installation of gas,non-stop refueling
2. Efficient air intake valve:The high quality air inlet valves can reduce energy consumption.
1. Large diameter and low pressure drop.
2.Improve system stability.
3.Ensure effective adjustment control during start-up,operation and stop traffic.
Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.
The costs of power consumption account for 70% or more of all costs during the operation. The electric charges of running air compressor account for more than 40% of all the electric charges in the factory.
The requirement of compressed air fluctuates violently in different time every day, different weeks, or different months every year. The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed drive screw compressor can meet the user’s requirement exactly. When the user needs less air delivery, Variable frequency inverter can reduce the capacity and reduce the power consumption at the same

To save the money
When buying air compressors, the traditional cost (ie, cost of purchase + maintenance costs), the proportion of only 25% of the total cost, while the energy consumption accounted for 75%.
Ordinary (frequency) air compressor than ordinary (power frequency) air compressor energy saving 22-30%;
Austrian Rendezvous permanent magnet variable frequency air compressor than ordinary (power frequency) air compressor energy saving 33-40%.
1. A 75KW ordinary air compressor, running 8000 hours a year, electricity 0.62 yuan / kWh, a year of electricity for the 75KW × 8000h × 0.62 yuan / (kw × h) = 372,000 yuan
Shanghai rotorcomp permanent magnet VSD 75KW air compressor, a year can save 35% of the electricity, a total of 372,000 yuan × 35% = 130,200 yuan;
