Sales - Chiller

Need for Chiller

Heat produced during any process is cooled by coolant. The coolant temperature has to be maintained so that it can be re-circulated back to the process continuously. Either ambient air or refrigeration system is used to cool the coolant.

Types of Coolant Cooling

Cooling system transfers the heat generated during process from one medium to another.

Cooling by Heat Exchanger - Air Cooled

The process coolant is cooled by forced ambient air using
fined tube heat exchanger.

Cooling by Heat Exchanger - Cooling Tower Water

Process coolant is cooled by cooling tower water using
shell & tube / Plate type heat exchanger.

Cooling by Refrigeration System - Chiller

When the required coolant temperature is below
ambient, process coolant is cooled by refrigeration system.

How to select chiller


Calculation of Chiller Heat Load

Selecting proper recirculation chiller based on following factors,

  The heat load generate by the process being cooled (Q in Kcal/hr)

  Maximum temperature of the process coolant exiting the process (Tout in °C)

  Required temperature of the process (Tin in °C)

  Density of the coolant (d in Kg/m3)

  Specific heat of the coolant (Cp in Kcal/Kg °C)

  Available process coolant flow rate (F in Kg/hr)


Heat Load (Q) = F*d*Cp*(Tout - Tin)
