Glycol Chiller & Brine Chiller Manufacturer in India

Airtech Cooling Process Pvt. Ltd. manufactures advanced glycol chillers and brine chillers engineered specifically for low-temperature industrial applications. These systems are designed for industries that require cooling below the freezing point of water, making them ideal for food processing, breweries, dairies, pharmaceuticals, chemicals, cold storage facilities, and industrial process cooling operations. Airtech's low-temperature chillers are available in both air-cooled and water-cooled configurations and utilize glycol or brine as a secondary refrigerant for safe, efficient, and reliable cooling.

Unlike conventional water chillers, glycol and brine chillers allow process temperatures to operate below 0°C without freezing the circulating fluid. This makes them the preferred solution for sub-zero cooling applications where precise temperature control and continuous operation are critical. Industry-wide, glycol and brine systems are widely used for applications ranging from food processing and breweries to pharmaceutical manufacturing and chemical reactor cooling.

Glycol Chiller & Brine Chiller

What is a Glycol Chiller?

A glycol chiller is a refrigeration system that uses a mixture of glycol and water as a secondary heat transfer fluid. Glycol lowers the freezing point of water, allowing the cooling medium to operate at temperatures well below 0°C without freezing. Glycol solutions are particularly common in food processing, breweries, dairy plants, and pharmaceutical applications where contamination concerns require safe cooling fluids.

Common Glycol Types

  • Ethylene Glycol (MEG)
  • Propylene Glycol (PG)
  • Food Grade Glycol Solutions
  • Industrial Glycol Mixtures

What is a Brine Chiller?

A brine chiller uses a salt-water solution (brine) as the secondary refrigerant. Salts such as calcium chloride or sodium chloride are mixed with water to achieve low freezing points and enable sub-zero cooling performance. Brine chillers are commonly used in chemical processing, industrial refrigeration, ice plants, seafood processing, and low-temperature manufacturing operations.

Why Choose Glycol or Brine Chillers?

Many industrial processes require temperatures below freezing, where standard chilled water systems become ineffective. Glycol and brine chillers provide reliable sub-zero cooling for the most demanding industrial environments.

How Glycol & Brine Chillers Work

Glycol and brine chillers operate using the vapor-compression refrigeration cycle combined with a secondary heat transfer fluid to achieve reliable sub-zero process cooling.

01

Refrigeration Cycle

The refrigeration system cools the glycol or brine solution inside the evaporator using vapor-compression refrigeration technology.

02

Heat Transfer Fluid Circulation

The chilled glycol or brine is circulated through process equipment, tanks, and reactors using circulation pumps.

03

Process Heat Absorption

The fluid absorbs heat from production processes, storage systems, fermentation tanks, or chemical reactors.

04

Return Flow

The warmed glycol or brine fluid returns from the process equipment back to the chiller unit.

05

Re-Cooling

The refrigeration system removes absorbed heat and restores the fluid to the desired low temperature setpoint.

06

Continuous Operation

The cycle repeats continuously, maintaining stable low-temperature conditions for uninterrupted production performance.

Glycol solutions are especially effective because they lower the freezing point of water and provide reliable heat transfer while protecting systems from freezing damage.
