Industrial Refrigeration Chillers

The industrial chillers we offer are built in closed stainless steel tanks. The rigid steel frame construction has a power coating finish and hence is weather resistant. It is designed to maximise exchanger efficiency. The heat exchanger is of coaxial type and uses copper tubes in a coiled tube in tube arrangement. This arrangement maximises heat transfer rate with minimum pressure drop. To further increase heat transfer efficiency, a counter flow pattern is used that achieves maximum temperature difference.

SALIENT FEATURES:

  • Compact - occupies minimum space
  • Built in closed stainless steel tank
  • Stainless steel high pressure pump for reliable operation
  • Microprocessor control (Optional)
  • Reduced Maintenance » More heat transfer area
  • Temperatures -5o to +30oC
  • Capacity: 0.75 to 100 TR

INDUSTRIAL CHILLER

SPECIFICATIONS

UNIQUE CO-EX HEAT EXCHANGERS:

(Mini series) The Heat Exchanger is of COAXIAL type, the design maximizes exchanger efficiency by using Copper tubes in a coiled TUBE-IN-TUBE arrangement. Tube sizes are carefully chosen so that fluid velocities are maintained through the tubes. This promotes turbulence break up boundary and maximizes the heat transfer rate with minimum pressure drop. To further increase heat transfer efficiency, a Counter Flow pattern is used that achieves the maximum temperature difference.

SPECIAL FEATURE OF CO-EX:

Full copper corrosion free heat exchanger Non-fouling exchanger Co-Axial arrangement, tends to minimize space requirement Minimises power consumption No leakage Low pressure drop High efficiency

BRAZED PLATE TYPE HEAT EXCHANGER (Max series):

The brazed plate heat exchanger is variation of the traditional gasketed plate type heat exchanger. It is designed to have lower pressure drop. It consists of stainless steel (AISI 316) plates and two end plates. The plates are brazed (99% copper) together in a vacuum oven to form a compact pressure-resistant unit. This compact design can easily be mounted directly in piping without brackets and foundations.

PUMP:

High pressure, high volume stainless steel impeller housing pump. It is with mechanical seal for long life and no leakage. The pump is capable of working 24 hours a day throughout the year. No need of stand-by pump. Pump motor has an overload protection.

TANK:

Stainless steel well insulated tank to save power due to no heat transfer from closed tank. FRAME: Rigid steel frame construction covered with easy removable steel covering, free accessible maintenance of all internal components, weather resistant power coating finish.

CONTROL PANEL:

Power and control panel is totally enclosed, dust proof, complete with all necessary switching, control and safety devices in accordance with applicable codes. Compressors are protected with overloads and safety trips.

GAUGES & SWITCHES:

Standard high pressure and low pressure refrigeration gauges. Adjustable low pressure and fan pressure switches for flexibility in operation. Unit is self contained of environmental and energy saving design. All equipment are factory tested prior to delivery.

OPERATION:

Adjacent plates form flow channels carrying alternately hot and cold media throughout the plate pack. All port connections are located in the fixed frame plate proving a low maintenance installation. Provided the number of passes is the same for both media nearly 100% counter-flow will be achieved

EASE OF INSTALLATION:

All chillers are shipped pre-piped and wired, ready to install and operate, installation is made easy with conveniently located Water and Drain connections.

ADVANTAGES:

  • Efficient heat transfer between refrigerant and water.
  • Low weight
  • Flexibility & easy by adding or removing plates

SERVICE:

GEM CHILLERS are designed to require minimum maintenance. Should service be necessary, a team of trained technicians is available to answer your questions about installation, operation and maintenance or repair. A complete inventory of spare parts is maintained at the factory and channel partners & local service providers located all over India.
