Refrigeration and cold chain

Refrigeration is among the most essential industries worldwide: it stands at the very foundation of our food supply due to the importance of the cold chain, it is also at the basis of the production processes for countless sensitive and vital products, such as drugs, vaccines and other pharmaceuticals. Refrigeration is also at the crossroads of major concerns: food safety on a large scale, as well as the preservation of our environment.

That’s why manufacturers and operators of refrigerators and freezers face increasing demands on operational safety and environmental protection. Pressure, temperature, superheating and subcooling of a refrigeration system must be regularly checked to ensure it functions smoothly, safely and efficiently.

The extensive international standards and regulations on the tightness of refrigerant systems are continually being revised. As the most used refrigerants are greenhouse gases with high global warming potential (commonly known as GWP), the regulations are becoming stricter. That’s why every part of the cold chain must be frequently tested: production installations, refrigeration plants, freezers, refrigerators, refrigeration units, etc.

Temperature and pressure

The two most important parameters for the maintenance of refrigeration systems are temperature and pressure, as they are the key to verifying the proper functioning of the cooling process.

The advent of digital technology means huge quality improvements when it comes to the adjustment of refrigeration systems or heat pumps. Digital manifolds provide high-precision temperature and pressure measurements, determine subcooling and superheating, but also enable reliable evacuation of the system through accurate vacuum measurement.

Thermocouple temperature

Kimo’s TK 61/62 digital thermometers are designed to accurately measure air temperature using an assortment of thermocouples.

Data logging

Data logging is an essential activity when monitoring the operation of a cooling system over an extended period of time and the temperature behavior within a cold store. Therefore, it is the main tool to ensure that the cold chain has not been broken during storage and transportation.

The recording of temperature and humidity data within a refrigeration or freezing area makes it possible to certify that the cold chain has been maintained throughout its most sensitive sections, primarily the transport of thermal sensitive goods like vaccines.

Given the massive health hazard involved in breaking the cold chain, data loggers enable the food and pharmaceutical industries to guarantee compliance with the strict quality requirements set out in international standards.

KT 50

Temperature

When straightforward temperature readings are required, look no further than to the KT 50 Mini Data Logger.

Data Loggers are widely used in agriculture, industry and clinical laboratories to monitor a variety of parameters.

Leak detection

Refrigeration systems can severely suffer from refrigerant gas leaks. Also, most refrigerants are powerful greenhouse gases and can seriously harm the environment. For this reason, it is extremely important to be able to easily locate any leak in order to quickly fix the impacted portion of the gas circuit. Searching for and finding gas leaks can be very difficult. Fast professional leak detectors are essential to precisely locate the smallest leaks in a refrigerant circuit.

Si-RD3

Refrigerant leak detector

The Si-RD3 refrigerant leak detector uncovers leaks of most common refrigerant gases to a high degree of sensitivity, including all HCFC and HFC refrigerants, R1234yf, R1234ze, R290, R600a, and 5% hydrogen–95% nitrogen mixtures (Nidron 5 and Trace-A-Gas).
