We are a reputed organization engaged in offering a quality approved gamut of Coolant Chillers. These are made by our dexterous professional, who use quality raw material and other components by taking aid of modern machinery, while keeping in mind the globally followed quality norms and standards. As a result of our efforts, these have longer service life and ensure reliable performance.

Refrigerated Coolant Chilling systems:

  • These
    can work at
    high spindle speeds, high feeds depth of cuts ensuring precision of
    highest quality.
  • As
    a result of this there is a huge amount of heat generated at the
    work piece / tool interface due to friction.
  • This
    heat reduce the tool life and also affects the quality of work.
  • Hence
    it becomes imperative to reduce the heat generated at the work
    piece, tool interface. This is accomplished by means of a fluid
    known as coolant.

Function of coolant in machining & grinding operation:

  • It
    cools the tool by absorbing the heat & hence enhances tool life
  • It
    provides lubrication to the tool & work piece interface
  • It
    protects the machined surface from corrosion
  • Reduce
    the cutting forces & hence the power consumption

Importance of Coolant Chiller:

  • As
    the coolant comes in contact continuously with the tool & work
    piece it absorbs heat and hence the temperature of the coolant
    rises.
  • With
    the rise in coolant temperature its heat absorbing capability
    diminishes and hence it further cannot cool the tool.
  • Hence
    it becomes vital to cool the coolant and maintain its temperature
    and other physical & chemical properties within prescribed
    limits.
  • This
    is accomplished by means of a Coolant chiller.
  • A
    Coolant chiller performs this function by exchanging the heat gained
    by the coolant with a refrigerant which is at lower temperature in a
    suitable heat exchanger.

Brief Description

Offered chillers consists of:

  • Compressor
  • Condenser
  • Condenser
    fan
  • Evaporator
  • Evaporator
    fan
  • Expansion
    valve
  • Accumulator
  • The
    necessary refrigeration controls & accessories

In any application the Coolant Chiller works in tandem with a Filtration system to deliver clean & cool coolant at constant temperature to the machining process.

Classification:

1. Based on the type of Heat Exchanger (Evaporator)

  • Immersion
    Type
  • Shell
    & Tube Type
  • Plate
    Heat Exchanger

2. Based on the type of Refrigerant

  • R22
  • R134a(Eco
    – Friendly)
  • R407C(
    Eco – Friendly)

Working Principle:

  • The
    coolant after coming out of contact with the Tool/Work piece
    interface is generally passed to a filtration system.
  • The
    filtration system cleans the coolant by segregating the fine dust,
    chips & foreign particles from the coolant.
  • This
    filtered coolant is allowed to enter the chiller where the coolant
    exchanges heat in the evaporator with the refrigerant and hence
    becomes cool.
  • This
    cool coolant is pumped to the process & the cycle repeats.
