Whether your end product is cream, butter, milk powder, cheese, or simply milk, temperature is critical in the dairy industry in order to minimize waste. Temperature plays an important role in creating dairy produce that is safe for human consumption. During the process, milk is passed through a range of cold and hot temperatures in order to kill off dangerous pathogens, as well as to preserve proteins and nutrients.

Using ammonia for refrigeration is effective, saves resources and is generally safe. However, because gas leaks cannot be completely prevented, ammonia monitoring is essential. An ammonia detection system reduces the risk of production downtime, protects employees, and can save seconds that make a difference in case of an alarm.

Risks involved with ammonia refrigeration

  1. Risk of explosion and fire
  2. Toxig dangers to humans


Field Applications

Personnel protection, workplace monitoring.

For protecting workers in the plant and or visitors in buildings portable and fixed instrumentation can be used.

Compressor and machinery room and ammonia tanks leak detection.

The machinery room houses, the refrigeration system, containing compressor, valves, pumps surge tanks and many joints it is prone to leaks. Small leaks might cause a constant background concentration.

Cold storage room leak detection and tainting protection.

A tiny Ammonia leak can have a damaging effect on stored goods. Small concentrations can taint food or other refrigerants or causes corrosion. Concentrations to be monitored are in the range up to TLV for getting early warnings.

Solutions from Dräger

Dräger Polytron® 8100 EC

The Polytron® 8100 EC is Dräger’s top of the line explosion proof transmitter for the detection of toxic gases or oxygen.
