Scroll Chillers:

Air-cooled Scroll Chillers are known for high energy efficiency. These are specially designed to work well within extreme tropical weather conditions. The chillers are tested in compliance with the international standards of the industry. These are operation-friendly and easy to install. The chillers come with numerous compressor configurations. Every compressor is backed by an individual refrigeration circuit. This separate refrigeration circuit makes its maintenance easy. The equipment contains a fluid pump and storage tank on the skid.

• Air-cooled scroll chillers boast a number of features which include :

1) Reliable and energy-efficient compressors 2) Environment-friendly refrigerant 3) Separate refrigeration circuits with every compressor 4) Electronic expansion valves for accurate temperature control 5) Tested tube evaporators 6) Automatic system and easy to operate

• Water-cooled Scroll Chillers and Features :

1) Water-cooled scroll chillers boast of being environment-friendly. 2) These are easy to install and can work well.

Centrifugal Chillers:

• EVAPORATOR-

An evaporator in a centrifugal water-cooled chiller is the heat exchanger that removes heat from the entering chilled water. A shell and tube heat exchanger is the most common configuration. The heat changes the refrigerant from a liquid to a gas. A flooded evaporator is an energy-efficient choice. Chilled water circulates in the tubes and refrigerant completely submerges the tubes in the shell.

• COMPRESSOR-

A centrifugal compressor converts rotational kinetic energy to the dynamic energy of fluid flow. Refrigerant enters the pump impeller and is accelerated, flowing radially outward, then exits. A frictionless centrifugal compressor uses magnetic bearing technology and a DC (direct current) motor drive. The process raises the pressure of the refrigerant by converting kinetic energy into pressure and heat.

• CONDENSER-

Similar to an evaporator, a condenser is also typically a shell and tube heat exchanger. The condenser removes heat from the refrigerant gas. The pressurized refrigerant.
