A chiller is a cooling system that removes heat by circulating a heat-absorbing refrigerant through a series of mechanisms through which the heat is released. The essential components of a chiller are a compressor, condenser, expansion valve, and evaporator. They work in unison to circulate a refrigerant that removes heat from a process, operation, or space.
There are several different types of chillers, each of which has a different process for removing heat. All chillers use air or water as a cooling method. For example, air cools a chiller system using fans, while a water cooled chiller circulates water with a cooling tower.

Like every other type of industrial equipment, chillers require operators to take necessary safety precautions. Ignorance of the potential hazards that chillers can pose may lead to industrial accidents such as refrigerant leakages or explosions that could cause bodily harm to workers.
To prevent these accidents, all chiller units must be operated within certain safety parameters
Dangers of a Lack of Chiller Safety
chillers use refrigerants that circulate in closed channels to achieve cooling. Maintaining the integrity of these refrigerant systems requires strict adherence to laid down safety and maintenance protocols.
1.Flow Safety Thermostat
A vital safety feature in industrial chillers is the flow safety thermostat. These devices detect adverse changes in temperature within the refrigerant circuit.
2. Freeze Safety
Freeze safety devices detect low thermal levels and switch off to prevent the refrigerant from freezing over. An automatic reset occurs when the temperature of the chiller fluid returns to normal levels.
3. Liquid Flow Switch
This mechanism detects a reduction in the volume of fluid entering the evaporator and automatically cuts off flow. The switch resets when fluid levels are restored to normal.
4. Compressor Safety Features
These compressor devices handle refrigerants circulating under a tightly regulated pressure range. Sudden increases or decreases in the pressure levels within a compressor unit can cause significant damage to the cooling unit and expose operators to toxic chemical leakages.
