Product Description

                Marine seawater cooled Cascade screw chiller 

Features
1.World famous brand new type and high-efficient screw-rotor compressor, with efficiency 20%~30% higher than those common ones. It has obtained several patents of Europe and America countries and passed the international quality certification of ISO9001.
2.High efficiency 5-to-6 rotor profile patent.
3.Capacity control apply to four-step (100%-75%-50%-25%),three-step (100%-66%-33%) and no step control system.
4.With 11 bearings and a balance piston against axial thrust. This extends longer bearings life 2.5 to 3.5 times than traditional design.
5.Designed with efficient silicon steel and special slots , and equipped with the inside and outside all around design to cool the flow channel so to ensure maximum efficiency of the compressor motor under any load.
6.Built-in oil pressing system ensure compressor maintaining the optimal lubricity without oil pump.
7.High efficiency double filtration oil separator ensures maxinum heat exchanger.
8.Efficient, low noise and small vibration.
9.Various options of refrigerants, R22, environment-friendly R134A, R407C etc.
10.All-wave compressor volume ratio(Vi=2.2/2.6/3.0/3.5) for selection to avoid the extra energy consumption caused by over or under compression.

1.Transportation of unit
(1). The chiller is packed in standard wooden box. We suggest hoisting if conditions warrant it. The forklift can be used during ground transportation. If the hoisting is made after the removal of packaging, pay attention not to put too much pressure on the chiller box. If necessary with the supporting rod to hoist.
(2). The units with wheel can be rolled on the ground and the units must keep balance
(3). Whatever way to transport, it must be carefully not to sway over not to collide so as not to damage
the equipment or endanger the safety of people.
★Not to use the forklift to transport the units after the package removed!
2.Installation of unit
(1).How to choose the installation location
Unit suitable for installation in the ambient temperature of -10~43 degrees, relative humidity of not more than 80% of the rain-proof shelter, or with the external environment has good ventilation conditions of indoor. In the wind direction is not less than 2meters of space, in a side condenser inlet wind direction should have 1.5~2meters of space. Units to be placed in no less than 20cm level solid concrete foundation, DLP-10AS and larger units with damping device, using the anchor bolt. Around the unit should have a working space, to facilitate the operation, inspection and maintenance.
