DX chiller manufacturer
We are the leading manufacturers of DX- Chillers to our clients.
The DX-Chillers are mainly used to cool he secondary refrigerants. The DX-
Chiller comes in shell and tube type where the liquid or air, gas is to be
cooled in the shell itself.
Evaporator manufactures are used for concentration or
crystallization of liquids. Shell and tube chillers ( evaporators ) are
extremely efficient.. An evaporator manufactures consists of either plate type
or shell and tube type heat exchanger.
The liquid refrigerant feed is cooled through an expansion valve
in the tubes which ensures superheated gas at the suction of the chiller. In
order to get a good heat transfer efficiency, baffles are provided in the
water, air passage in the shell of the chiller which helps in maintaining
good velocity of water, liquid or air over the tubes.
Approximately 50% to 75% of the tubes are immersed in liquid
refrigerant and the space above provides an allowance for the vapour generated
through evaporation of the liquid below. This type is more often used with
screw or centrifugal type compressors.
For cooling the secondary refrigerants, chillers are used. In
working the DX chiller is similar to the dry expansion coil. The liquid
refrigerant feed is through an expansion valve which ensures superheated gas at
the suction outlet of the chiller. Mainly it is shell and tube type. The water
or liquid to be cooled in the shell, while the refrigerant is in the tubes.
Baffles are provided in the water passage in the shell of the chiller, thereby
maintaining good velocity of water/liquid over the tubes to get good heat
transfer efficiency.
The concept of the shell and tube chiller is based on a large
number of tubes formed into what is known as a tube bundle. Refrigerant flowing
from the expansion device is passed into the tubes and progressively evaporates
thereby producing a cooling effect through the latent heat of vaporization.
