How can Testo instruments help with refrigeration maintenance?

While refrigeration and air conditioning systems are essential for plenty of businesses to remain operational, they can become dangerous if not properly looked after.

Like most machinery, these units require regular maintenance in order remain running safely and effectively. The following tips provide examples of how these systems can fail, and what Testo instruments can do to help.

1. Watch for overheating

All machinery has specific operating temperatures that it must be kept running to. Failing to respect these guidelines can result in engines and other important components becoming damaged or failing altogether.

With motors of many sorts powering various refrigerator and air conditioning units, it’s important to make sure these are running at the correct temperature. If not, the system could be compromised or may cease to run if they motor is allowed to die.

Temperatures can be monitored with thermal imaging cameras. These devices allow for the supervision of systems that are dependent on specific cooling requirements to remain operational.

2. Prevent leaks

Refrigeration units and air conditioning units rely on gases to heat and cool efficiently. Some of these, such as ammonia and carbon dioxide, can be harmful to humans if encountered in the wrong conditions.

Some refrigerants are also greenhouse gases, or CFCs. Leaking these substances can harm the environment as well as people, and have been deemed partially responsible for issues surrounding global warming.

For this reason it is important to check vital systems often, ensuring any at-risk areas are still correctly sealed and not leaking any contaminants. Instruments such as the Testo 316-4 can detect the most common refrigerants, allowing easy inspection for most standard installations.

3. Maintain correct pressures

These systems rely on correct pressures to accurately and continuously maintain temperatures. Changes in pressure, either high or low can put undue strain on units, opening them up to the possibility of mechanical failure.

While most modern systems have high and low pressure switches that can detect anomalies, it is still worth performing these checks yourself to ensure everything is functioning correctly.

Tools such as the Testo 570-1 data logging gauge can measure the pressure of your units as well as temperatures, providing a comprehensive maintenance solution.

4. Perform checks regularly

Perhaps the most important point is to carry out these tests on a regular basis. These measures mean nothing if they are only performed sporadically. Having a maintenance schedule that all staff follow can ensure any issues that arise are caught promptly.

This keeps both your equipment and your employees operating effectively, saving money and time in the long run.
