Refrigeration is based on R407C, controlled by a thermostatic expansion valve, operating at 7C evaporation and 50C condensation, and suitable for ambient temperatures up to 45C. Chilled water temperature is regulated within +10C to +20C.

Chilled water flow is 6000 LPH at a 35C temperature differential. Heat rejection is performed by an air-cooled condenser with copper tubes and aluminum fins, supported by four axial suction fans of 28-inch diameter. Each fan is rated at 0.65 kW, producing a combined airflow of 30, 720 CFM, mounted on a galvanized steel structure.

Compression duty is handled by one semi-hermetic screw compressor manufactured by Bitzer, rated at 63.9 kW with a current draw of 105.4 A at 50 Hz. Motor starting is via stardelta, while step capacity regulation from 0% to 100% ensures stable performance under varying load conditions.

Cooling exchange is achieved through a shell-and-tube evaporator featuring a powder-coated carbon steel shell, inner-grooved copper tubes, and SS-304 TIG-welded baffles and headers. The assembly is designed for 10 bar working pressure and hydrostatically tested at 15 bar, with 3-inch BSP chilled water connections. Heat ingress is limited using 40 mm closed-cell PUF insulation.

A factory-integrated circulation pump rated at 3.75 kW (5 HP) delivers 50, 000 LPH against a head of 2.33 kg/cm. Condenser-side refrigerant piping is 3/8 inch. Safety coverage includes high/low pressure protection, motor overload, phase reversal monitoring, flow interlock, anti-freeze logic, discharge temperature cut-out, internal thermostat, and low water level protection.

Control and monitoring are provided through a factory-assembled electrical panel comprising MCBs, contactors, overload relays, timers, PLC, and HMI, fully wired and tested prior to dispatch. Overall dimensions and GA drawings shall be submitted after order confirmation.

A glycol chiller is a refrigeration system that uses a glycol-water mixture (usually propylene glycol or ethylene glycol) to remove heat from a process or equipment. It's commonly used in industries like:

• Breweries and wineries (to control fermentation temperature)

• HVAC systems (as part of cooling loops)

• Food and beverage processing

• Medical and pharmaceutical manufacturing

• Plastics and laser systems

A Commercial Chiller System is a type of HVAC (Heating, Ventilation, and Air Conditioning) equipment used in large buildings and industrial facilities to provide cooling by removing heat from a liquid, typically water or a water-glycol mix. This cooled liquid is then circulated through a network of pipes to air handlers or fan coil units to cool air in the building.

A blow moulding chiller is a specialized industrial chiller used to cool molds and plastic parts in the blow moulding process—a method commonly used for making hollow plastic containers like bottles, tanks, and drums.blow moulding chiller:

• Provides precise and consistent cooling during the moulding cycle.

• Removes excess heat from:

  • Moulds (to maintain shape and dimensional stability)

  • Hydraulic oil (to prevent overheating of machines)

• Increases cycle speed, product quality, and energy efficiency.

An acid chiller is a specialized type of chiller designed to cool corrosive acids or acid-based process fluids in industrial applications. These systems must be built to withstand highly corrosive environments, making them very different from standard chillers.

Acid chillers are typically used in:

• Chemical processing plants

• Pharmaceutical manufacturing

• Metal finishing and etching (e.g., for semiconductors or PCBs)

• Battery manufacturing

• Pickling lines in steel production
