Product description:

With the development of modern science and technology, the diversification of products requires that some processes and equipment can not meet the requirements of room temperature water, such as pharmaceutical chemicals, food and beverage, special electronic materials such as the production of these high-end industry often need low temperature freezer to meet the requirements The For many large-scale low-temperature refrigeration needs, Davos production of low-temperature screw chiller with higher energy efficiency screw compressor.

 

Features:

1, the most efficient semi-closed screw compressor, the heart of the unit - imported high-quality screw compressor, its 5: 6 ultra-efficient screw rotor compressor, 20-30% higher than the average compressor efficiency. Easy, accurate capacity control, wide range of applications.

(1), the latest asymmetric rotor tooth profile;

(2), four or no stage capacity control system;

(3), built-in differential pressure oil lubrication system;

(4), low vibration, low noise.

2, the computer to accurately control the temperature, the unit microcomputer controller using large screen dot matrix LCD display, with a good all-Chinese man-machine dialogue interface to achieve full-featured automation control. LCD display real-time machine work conditions, accurate monitoring group running in the best State, the touch panel seal is good, waterproof, dustproof, corrosion-resistant, long key life. Rated and non-polar energy control, for general air conditioning systems, equipped with 100%, 75%, 50%, 25% rated energy control system.This ensures that the unit in the part of the load to maximize the energy efficiency.However, if you need precise control of water temperature, According to user requirements, all models can be equipped with stepless energy control.

3, high efficiency, heat exchanger with a high efficiency bellows, plus efficient screw compressor, to ensure the efficient operation of the unit. The most reliable protection and auxiliary components.

4, screw chillers have the following components to prevent any operational failure: compressor protection design timer, over-current relay, compressor motor temperature sensor, anti-freeze thermostat, LCD mirror, oil heater, compressor reverse Phase protection relay, high and low voltage protection, exhaust high temperature protection, safety valve, easy to plug.
