LQ Water Cooled Screw Chiller 

Water cooled screw chiller imported semi enclosed twin-screw compressor is selected. Water cooled screw chiller compared with the traditional reciprocating compressor, water cooled screw chiller has the characteristics of high efficiency, quiet operation, simple operation and long service life. Termsof Payment 30% deposit by T/T when confirming the order, 70% balance by T/T before shipping.Or irrevocable L/C at sight. Installation and Training The price includes the fee of installation, Training and interpreter, However, the relative cost such as international return air tickets between China and Buyer's country, local transportation, accommodation (3 star hotel), and the pocket money per person for engineers and interpreter will be born by buyer. Or, the customer can find capable interpreter in local. If during Covid19, will do online or video support by whatsapp or wechat software. Warranty: 12 months after B/L date. It is ideal equipment of plastic industry. More convenient and easy to do adjustment, save labours and cost to support our customers do more effierency.

Products Details

Characteristics of machine unit  ● The imported semi enclosed twin-screw compressor is selected. Compared with the traditional reciprocating compressor, it has the characteristics of high efficiency, quiet operation, simple operation and long service life. ● World famous refrigeration components are adopted to ensure the quality and stable operation of the unit. ●The evaporator and condenser adopt high-efficiency thread heat exchange copper tube, which has high heat transfer coefficient. At the same time, the evaporation inside the tube and the condensation outside the tube have high heat exchange efficiency, which ensures the good refrigeration performance of the unit. ●Independent refrigeration circuit can be maintained and overhauled independently without affecting the use of the whole machine. ●The unit is controlled by Siemens micro-computer programmable controller, which can timely and accurately control the matching of cooling capacity and cooling load with the compressor subsection energy regulation system, so as to ensure the highest operation efficiency and the lowest energy consumption of the unit, and realize reliable energy-saving operation.
