Product Details
250 Ton 900 Kw Air Cooled Screw Compressor Water Chiller Description
1. Adopt low-rotational radiating fan, which discharge the heat smoothly, so the noise level is obviously reduced. The unit control system adopts small vibration, easy to install. It is favorable for where is water shortage, and water -cooled tower is not installed.
2. According to load requirements, unit can realize automatic programmer control and saved the energy consumption. The human machine interface configures a full touch screen, which is accurate monitoring. Applies step and stepless capacity control to reach the maximum energy efficient ratio.
3. Imported special air-cooled (semi-hermetic) screw compressor with a famous brand, which is reliable operation, high efficiency, easy maintenance, exact volume control, and has a wide range of application. The system adopts the latest asymmetric rotor profile, build-in pressure drop lubricant to system with low vibration, low in noise, high performance.
4. Complete protection device: to prevent compressor starting frequently, over-current protection, overheat of motor protection, prevent freezing, sight glass in liquid, oil heating protection, phase protection. HV/LV protection, discharge high-temperature protection, safety value, soluble chock, water shut-off protection.
5. Field of application: Laser, Chemical, Plating and oxidation, Precision Instruments, Printing, Ink, Paper, Metal, Casting, Blowing, Injection Plastic Industry, Food Processing, Pharmaceutical Industry, Electronic Circuit Board, Wave Soldering Reflow, Interlayer Cooling, Space Purification Treatment, Ultrasonic Cleaning, Bath temperature control, Cutting and Welding, Surface Treatment, Aluminum, Glass Crafts, Jewelry Processing, Leather and Aquaculture .
6. Unit design has a full intelligent control system and non-stop running within 24 hours.
