Detailed introduction

RWKII product line includes RWKIi-CM screw type refrigeration compressor unit, RWKIi-Cu screw type compression condensing unit, RWK II-BC/RC screw type refrigeration brine unit and RWKIi-IC& EC special brine unit for ice rink. Operating temperature :10℃ to -45℃

· Modular design, compact structure, performance and cost

· York twin screw compressor, rotor for advanced asymmetric profile design, high efficiency and energy saving; The supporting anti-friction rolling bearing has 100,000 hours service life of class L10 under design conditions

· 100%-10% stepless energy regulation for slide valve control

· Compressor is designed for operation without lubricating oil pump, all injection and lubrication are achieved by positive pressure difference

· Oil separator is a three-stage separation design with horizontal and integrated oil groove, and the replaceable accumulation separator can make the final oil and gas separation particles less than 1 micron

· The compressor oil cooling method adopts spray type oil cooling, the unit structure is compact, convenient maintenance

· Low noise open motor, connected with the compressor through the D flange, so that the installation is easier, and no need for field alignment

· Adopt advanced SmartViewII controller, can realize the compressor and refrigeration system of the main operating parameters display, automatic control and safety protection, with powerful data processing and expansion functions, with Chinese/English display, can adapt to the needs of various applications · All series of units adopt brazed plate heat exchanger as economy, compact structure, high heat exchange efficiency, can greatly improve the refrigeration capacity and refrigeration efficiency of the unit

· Shell and tube condenser adopts new efficient heat transfer tube bundle, the inner wall strengthens heat transfer, the outer wall is fin, and the expansion tube has good sealing property, each tube can be replaced separately, and the maintenance is convenient

· Dry evaporator adopts new efficient dry heat transfer tube bundle, the inner wall strengthens heat transfer, and the expansion tube has good sealing, each tube can be replaced separately, easy maintenance; The water side baffle can make the chilled water evenly distributed along the whole direction of the shell. The refrigerant side tube box is specially designed to ensure the uniform distribution of refrigerant and the heat transfer efficiency is good
