EKDC series water-cooled falling film centrifugal chiller adhering to energy saving and environmental protection of the brand concept, can provide chilled water for central air conditioning system in hotel, hospital, pharmaceutical, theater, stadium, recreation center, commercial building, office building, industrial and mining enterprises; also can for textile, chemical, food and electronic research to provide chilled water for process usage.


Environment Friendly Refrigerant

R134a is environment friendly refrigerant, zero ozone depletion, safety & non-poison, un-burnable, green & environment friendly, comply with current development trend of international environmental protection.

High Efficiency two-stage Compression Design

Using high efficiency two-stage hermetic impeller compression increases efficiency more than 6%, lower relative speed, lower noise level, small vibration, higher reliability. Adopting three-dimensional flow high efficiency aluminum hermetic impeller design, greatly decrease air leakage; five-axis machining with higher precision, so can effective reduce impeller axis loss and separate loss, and greatly increase impeller efficiency. Than unit efficiency is better than national standards for energy conservation.

Reliable Oil Recovery Device-Induced Jet Pump

Through induced jet pump, on the condition of no energy loss make use of middle pressure steam flashing to achieve low pressure side oil recovery function.

Refrigerant Flow Control Kit-Orifice Plate

• Use orifice plate to control refrigerant flow. Each set orifice plate is designed and produced according to Centrifugal Chiller performance; so that can get the best match.

• Orifice plate without any moving part, so that it is more reliable than the other throttle valves that need mechanical transmission

Spray Type (Falling Film) Evaporator

• The refrigerant into the evaporator is a heat exchange tube array on the spray direction. The liquid refrigerant in the tube wall to form a thin film flow down, also known as the falling film evaporator. Because only in the surface of the heat exchanger tube is covered with a layer of liquid refrigerant film, so the heat transfer effect is excellent

• Using refrigerant circulation pump as the refrigerant throttling device from economizer to the evaporator, meanwhile pump out liquid refrigerant in evaporator bottom for recycling; in order to improve the refrigerant supply for evaporator upper copper pipe, so that can make sure that all copper pipes are covered by liquid refrigerant. Unit no need precise water level correction, only for general positioning, evaporator can play high normal performance.

• Only evaporator bottom has a small amount of liquid refrigerant so that refrigerant charge is less, complying with environment protection.

• After a large amount of refrigerant evaporation, lubrication oil concentrate in evaporator bottom; and then oil pump can draw out lubrication oil smoothly and then oil back to compressor oil groove.

High Efficiency Advanced Centrifugal Compressor

Centrifugal compressor has two-stage compression, internal using high strength alloy main shaft and hermetic impeller, using high precision gear, using non-flat high strength ball/roller bearing; so that emergency stop is ok. Unit start interval can be shortened to 10 minutes, and bearing life can up to 80000 hours.

High Efficiency Condenser

Condenser is divided into two parts, guide plate installed in the middle that can guide liquid refrigerant to the shell edge, can greatly improve lower copper pipe heat exchange efficiency. For large tonnage unit, this design is very effective, can reduce condensing Temp. 0.5~1℃.

Authority Certificate

We have industry’s most advanced test room for centrifugal chiller, this test room has passed China National Accreditation Committee audit qualification (CNAS L5123), strictly complying with GB/T10870-2001, GB/T18430.1-2007; testing capacity up to 3000RT. Before delivery, each unit has done strict full performance test to ensure unit performance.
