We can also supply DOL Star Delta control boxes and ABB, Danfoss, Mitsubishi and most other brands of inverters.

We are also experts in Infrared Thermography. Infrared Thermography is a technique that is used to gather thermal information from any object or area by temperature and converting it into a visual image.

A bi-product of electricity and friction is heat, which varies depending on how much current or friction is present. When an appliance malfunctions, either mechanically or electronically, the normal working parameters of the components are altered, which often causes unwanted side-effects. The most obvious is an actual breakdown, the less obvious is an increase in heat to the affected areas. On complex systems this is often hard to locate. We use an infrared camera to identify areas under stress in machinery, installations or electrical equipment due to increases in working temperatures.

Vibration Analysis - Reports suggest that shaft misalignment is responsible for almost 50% of all rotating machinery breakdowns.

Frequent machine breakdown is often the result of additional wear and tear caused by shaft misalignment. Angular or parallel shaft misalignment places additional and unequal strain on moving parts. Misalignment also increases energy consumption and increases running costs.

LERs Laser Shaft Alignment program is the perfect solution to this problem and combined with a thermographic inspection, LER can identify machinery parts that are at risk. A Preventive Maintenance Schedule save on repair costs and the associated costs of downtime and lost production.

We have the capability to meet your laser alignment and metrology needs, and provide services for a wide range of rotating equipment. We lead the field in measurement services using the latest technology available and adapting it to a wide range of applications.
